The strategies—corporate, competitive and current—and the “effective leadership”, provided by linear management—all in all 22—were briefly presented with an application to shipping industry, like BCG matrix, and growth, as well as how to create and maintain a competitive advantage. Moreover, the essential strategies/functions of a shipping company were too presented with the prime emphasis to timing of shipping decisions. In shipping, management, as showed, is done by distance. Nonlinear management strategies showed next and the full Cartesian diagrams-phase spaces—of 3 companies— one in shipping—were used to discover the level of chaos in their business activities. A further tool has been used from nonlinear management: the “span of management” vis-à-vis the well-known “span of control”. We have showed that both top maritime countries and top shipping companies pursue the “ growth strategy in a related industry” (with same knowhow). Some countries did it better, like Greece and Germany. “Growth strategy” has been accompanied by economies of scale and a lower service cost. We showed also that a growth strategy has to be moderated by: 1) forecasting that demand will be there, when ships are delivered; 2) that liquidity is secured, even in a slump, where banks and stock exchanges turn their backs to shipping, 3) the fact that prices of ships—new or 2 nd hand—were indeed at rock bottom and that the 1 st -best or 2 nd best timing has been applied and 4) that company’s investments did not influence total supply so that to dampen markets. A mention on generic competitive strategies has been carried out and especially differentiation issue of products and services, but not pursued much as shipping has homogeneous services.
This paper provides several presentations: one is the concise analysis of what we have called “linear strategic management”, which is the mainstream management strategic theory. For this we have used the most up dated source in USA, including current strategies. We have been surprised for the extensive list of strategies that theory provides, where we have counted 22 various strategies… From this list we have singled out the ones that have been used by shipping companies like: growth strategies including economies of scale and cost leadership.
The 2nd presentation concerns the essential roles and strategies that a shipping manager has to perform, where timing of the decision-making holds the prime place. The 3rd presentation deals with the important concept of linear management like mission. The 4th presentation deals with nonlinear management strategies, which cover a more extensive analysis as we have presumed that the reader may be unaware of it.
Worth noting is that: the definition of “strategic management” is tautological, as it says that strategic management is “what managers do to develop organizations’ strategies”… applying a strategy does not also mean “making money”, and the 1970 “strategic planning model”―invented by “General Electric Co”―a 7-step process―is static.
This last model gave 43% attention to company’s mission and to the application of SWOT analysis. It gave also attention to present, which no one can change. SWOT―as it is known―is a composite concept meaning company’s external analysis for: threats, opportunities and internal analysis for: strengths and weaknesses. The other 57% of the model was: 1) to recognize 3 strategic issues (growth, risk, competition), 2) to identify strategic alternatives and 3) to decide upon them. There was no evaluation of strategies’ step.
Modern authors removed 2 of the original steps of SPM and added a 6th step (= “evaluation of the results of company’s strategies”). Evaluation was necessary no doubt. Two steps removed―wrongly: the “identification of alternatives” and “the decision-making of them”.
One aim is to introduce the tools of nonlinear management by showing its usefulness vis-à-vis linear management. This is done with a number of graphical applications (using the full “Cartesian” diagram) to 1 shipping company and 2 shore companies. Second aim is to present briefly the existing fourteen linear strategies, and review them. Emphasis all along is given to those strategies applied by, or applicable to, shipping companies like growth strategies, economies of scale, and timing of decisions.
The paper is organized as follows: next is a literature review, followed by a brief presentation of the (14) existing linear strategies. Then, the main functions performed by a shipping company are presented by order of importance. Next, a presentation of the linear management central concept of “mission” is done. This is followed by a presentation of the nonlinear management strategies. In addition 3 case―studies of companies are shown in their “phase spaces”1―in- cluding the case―study of a major shipping company in the transportation of “oil-products”. Finally, we conclude.
Research on “shipping management” is rare, and of a rather late appearance, despite its great importance. The pioneers in this endeavor belong to 4 schools:
√ The Norwegian school (1973) represented by: Lorange and Norman (editors) 1973 [
√ The American school (1973), represented by: Kendall l C (1912-1999); Buckley2, 2008 [
√ The English school (1981) represented by Packard4, 1981 [
√ The Greek school (1992) represented by Dr. Goulielmos, (2004 [
The lack of shipping management studies are due―we believe―to the fact that most maritime authors in Academe ignore shipping management and those in shipping management do not become academics―with few exceptions. There is also the secrecy of the actions of shipping industry, excluding “listed shipping companies” and/or “those that provide management” to other shipowners for a fee. Listed shipping companies are transparent and as a result Academe is informed indirectly about their actions and strategies.
Interesting is Mr. Peter Lorange, who is Professor of International Shipping at IMD (Lausanne) and former owner of a Norwegian shipping company (2007). Lorange (2009 [

In summary, we see that research on shipping strategic management has been poor and of a late appearance and as well from a limited number of authors, so it is not surprising to see almost a non-existing research also on nonlinear shipping strategic management.
According to linear management studies-LM a manager has to “identify company’s mission, goals8 and strategies9”; then carry-out external and internal analyses; the 4th step is to formulate 3 composite strategies of… 14 particular strategies, i.e. the corporate, competitive and current. The 5th step is to implement the strategy (-ies) chosen, and the 6th step is to evaluate10 their relevant results.
LM theory argues that “strategic management” helps for a good “performance”, and that there is a positive relationship between “strategic planning” and “performance”. Our personal opinion is that a flexible (
√ The corporate strategies consist of 4 particular strategies (
Interesting is BCG for shipping, which could classify company’s ships in 4 categories… and sell first the “ships-dogs”, and eventually the “ships-cash cows”… and perhaps increase―by buying or building―the “ships-stars” and “ships-question marks”… The ships-cash cows must be kept till a slump is over for liquidity purposes.
√ The dominant strategy: growth
This is to “maximize the size of the company”. This strategy means―for shipping companies―“maximization of the fleet-owned”, or more accurately the “amount of dead weight tons12-owned”13. Below (
This “growth strategy” is shown among the global top 10 maritime nations (
As shown, 10 leading shipping countries globally spent ~?76b (67% of total) in 2007 (a boom year) to order 3371 ships (~63% of total). Germany is first in
number of ships ordered with 963 units (29% among top 10); Japan―a leading shipbuilding country―is leader in the funds spent of ~?7b or 21% among top 10.
Interesting is to see economies of scale (
As shown, Greece and Germany achieved the lower prices, fact which will make them more competitive in future. The new ships―we reckon―are larger than hitherto, and this indicates not only a growth strategy, but also economies of scale. Economies of scale―as this is known―provide cost advantage (given demand).

Next, we present the fleets of 10 top Greek shipping companies in 1990 and in 2000, having exceptional (double) rates of growth in tonnage. This is shown by the different amounts marked on vertical axes of
The growth strategy we saw above means additions of identical operations with a view to gain advantages from additional economies of scale, where know how is unchanged or improved by learning (best example: Greek shipping).
There are also many examples for growth in related industries (called circular), 2 of which can be14 found in Lorange (2009, [
In shipping we have also seen many cases of mergers (e.g. “OMI shipping Co” bought by “Teekay”), i.e. effort of one listed company to buy-out competitors. Growth in unrelated industries positions a company in 2 independent markets, but there is a risk due to diversification. Shipping is a cyclical industry and an investment that provides profits during a shipping slump is desirable. Most shipping companies resort to investments in real property considered them of a stable rising value. Moreover, shipping companies diversified their fleet by entering in ships, sizes and markets unknown to company before (e.g. product carriers; VLCCs & ULCCs; LNGs; LPGs; car carriers; gas carriers; vale carriers etc.).
√ Competitive strategies
“Competitive strategies” is another composite concept, including 4 particular strategies (
A shipping company does not set off in “strategic business units”, but many times sons and daughters―after the death of their father-shipowner―set off new companies (Goulielmos, 2017 [
Most important is the strategy to create and sustain company’s competitive advantage(s), using 3 particular methods/tools: (1) quality, since 1991, (safety for
shipping since 1998); (2) social media (a contemporary tool) and (3) design thinking (a modern approach since circa 2006).
Design thinking means―for shipping―to have charterers to be able to find anything they want on line; or it means―in general―approaching management problems16 the same way one solves design problems (e.g. “Kiva systems”, a Chinese company). USA shipping company OMI (bought by Teekay) had the chartering of its ships on line. Social media can be useful for the communication of large company’s staff (say 250 - 300 persons) of shore office with ships’ crew amounting to 1500 for large companies. In addition, “big data” may appear a strategic weapon for shipping acting internationally, as all big global events influence shipping.
“Quality” of products creates a competitive advantage, but in shipping we need “quality of services”. “Quality of shipping services” is confused with “safety”. “Total safety management” is in shipping required for a shipping company to be considered “standard”, but this does not influence the level of the payments of freights; lack of safety is illegal17, however, and charterers demand it... A shipping manager will not permit charterers to consider his/her company of having “sub-standard” ships―though safety means cost. Some shipping companies try to differentiate their services―or rather show off―by obtaining ISO standard for management and/or for environment.
Theory considers the creation of a competitive advantage difficult, but to sustain it―we reckon―is more difficult... Certain shipping companies may excel in caring to satisfy their charterers, providing safety on board (and security in ports complying to ISPS18 code―2004), having a minimum of loading/unloading interruptions (black-outs), being polite and willing to respond to the demands of the charterer that do not cost anything to owner etc.
√ Secure cargoes: a unique shipping strategy
A superior shipping strategy followed by shipping entrepreneurs, was and is, to secure―somehow or anyway―cargoes, perhaps by creating best personal public relations with cargo-owners. Best example of international public relations was Onassis in his unsuccessful effort to secure part of the Saudi Arabian oil transport, using a win-win strategy.
Another example is “Gearbulk” in Brazilian pulp business concerning the companies “Aracruz”, “Suzano” and “Votarantine” (Lorange, 2009, [
√ Current strategies (6 strategies) (
As shown, strategic leadership―but not effective―is a composite task, or a shopping list, requiring: ability to anticipate, envision, maintain flexibility, think strategically, and work with others―in house―to create a viable and valuable future…In strategic flexibility, we have to recognize the major external changes, to commit fast required resources and recognize a wrong strategy19. The 1st mover has 4 advantages and equal disadvantages, and applied also to shipping. As shown, 3 current strategies are more important: e-business, innovation and be close to customers.
All shipping companies have to carry-out, and plan yearly, key-tasks, which are next presented by order of importance. Worth noting is that a shipping company is a “multi-plant” firm, where its factories = ships, are floating, and move internationally, and more important is that management is done by distance, as the manager is in the shore office―say in Piraeus―and the ship miles away―say in Arabian Gulf.
Cheap and fast communications are thus vital for the shipping industry. This means obligatory delegation to Captains. This further means the need of an increasing control (by distance). This also means increased formalization (rules and procedures), and the inability to control in advance. Errors can only be punished! This further means the importance of the selection procedure of Captains as co-managers, and not as crew.
√ 1st-best timing
This is the most important shipping managerial strategy: i.e. the proper “timing of shipping decisions” (Lorange [
As shown, the cyclicality of new building prices over the last 29 years is clear, and the period of “shipbuilding cycle” according to theory (Pearce, 1992 [
Shipping managers, with the ambition to grow their companies―following a fast growth strategy―usually, rush to premature orders and acquisitions of ships. Then, they realize a few years after that the same ships to be valued at 1/3 of what they have paid!
As all shipping variables change rapidly, the 1st-best timing concerns shipping decisions starting from this question: “Is this the right time―of all past times ―for us to…?” The 1st-best timing, however, has its own speed and is this speed managers should have, if they want to apply timing. Crucial here is how the company has organized its information flow, as the shipping international reality changes from a minute to next. Ships, anyway, work 24 hours…
Fundamental for shipping companies is also to know if they act in markets “permitting” price-taking, where the tools of marketing are of limited help (Goulielmos and Plomaritou, 2009 [
take into account similar or identical market conditions, as well as other essential factors.
An individual manager should thus control company’s cost. “Cost minimization” is the 2nd proper, and permanent, we would say, strategy, after “1st-best timing”, and especially during slumps. As shown (
The fixed price dictates also to a manager what is known as “in-and-out” policy (Lorange, 2009, p. 42, [
√ To understand economics
A manager has to deal primarily with company’s loans, and to design how to “manage”: company’s financial flows20, the budget, the currencies, the interest rates, and the new instruments and derivatives (related to FFAs = forward freight agreements). It is estimated (Lorange, 2009 [
The knowledge of economics of various markets (bulk, tanker, containerships etc.), and of their sub-markets, is essential, as shipping markets have different characteristics. Certain shipping companies hire economists for this, especially those with prior good banking public relations. Most shipping companies “keep” this function wrongly for company’s management for reasons of confidentiality. Shipping managers most of the cases lack knowledge of economics, and finance, excluding current generation, which studies “money and finance” in various masters’ degrees. When markets turn, is crucial this to be spotted beforehand by the able manager, but accurate forecasting is the weak point of this industry (Goulielmos, 2017 [
A factor, which bankrupted shipping companies many times, is the lack of liquidity, especially during a slump. To the same effect works also a prior ambitious newbuilding program coincided with a subsequent fall in rates upon ships’ delivery. After a slump, banks21 and stock exchanges―unfamiliar with shipping cycles―are reluctant to provide credit. To face this, shipping manager needs economic expertise. The adoption of “crisis reserves” from past profits, given the cyclicality of shipping markets, is e.g. wise. Strategic companies have to “manage” their loans so as to adapt loans to22 company’s cycle and avoid defaults.
√ To charter ships
Sales = chartering: to let ship’s space for hire, or for freight, (the failure here is “total”); chartering expertise may not be a property of all shipping managers; in that case, a large company relies heavily on a number of specialized in-house ship-brokers. As this function achieves the sales of the company, it should be placed in the 1st and prime position in a company. If a company has a top manager expert in chartering, this may become a “competitive advantage”, and the relevant particular policy for the company is to select the most profitable, in the end, charters among all other offers.
・ To operate ships
Production = operations: i.e. to implement a “charter party” as agreed by company’s chartering (a failure here damages company’s reputation in the eyes of charterers); a non-failure brings-in a number of benefits. The policy needed here is to “minimize the off-hire23 time of ships”; and satisfy charterers.
The successful operation of ships is a 2nd important task of a shipping company, occupying also most of company’s time24. In operations a manager should manage not only costs, but also company’s revenue-something neglected. This is a function connected with company’s performance and it is here where company can be close to charterers.
√ A shipping company closer to charterers
Traditionally, it is true, that shipping industry did not pay attention to its customers (Lorange, 2009 [
Eventually, a sense of safety created―under the pressure of certain marine accidents, where management had clearly failed (Goulielmos and Goulielmos, 2005 [
While any payment to owners does not depend on safety, and on all the above mentioned factors―when available cargoes are fewer than ships―safety of service counts and charterers prefer “safe ships of low age”. This may be called “no price competition”―NPC, though none of NPC characteristics applies much to shipping: advertising, marketing, and service innovation.
In addition, “management” changed its focus from the supply side (technical perfection in production) to demand side (sales; customer’s satisfaction etc.), following “total quality management”25 (TQM) (since 1991) (Priesmeyer, 1992 [
√ To maintain ships, to innovate
The policy required is related to changes that a manager (more so if he/she is a former engineer/naval architect) asks ((through his/her supervising superintendent engineer(s))―in the case of a shipbuilding contract. This is connected with “innovative management”. Also, the technical evaluation of 2nd hand ships is also of utmost importance in the acquisition process. The technical side of ships is the most difficult for managers without a prior technical expertise―a case where a manager is obliged to rely heavily on his/her technical manager. Linear and nonlinear strategies will be now presented, and distinguish ones from the others for a possible benefit to shipping managers from both28.
“Linear Management-LM”―strategies are plans, of how: a company will carry-out its businesses; it will compete (its competitors) ―successfully―and it will attract (and satisfy) its customers, by achieving company’s goals29 (Robbins and Coulter, 2012-16, p. 645 [
√ Company’s mission
Mission is central. The past status of a company―we believe―needs to be known, before a manager plans to make it strategic or more strategic. The mission (
Mission, normally, determined long ago by company’s founder. It was perhaps a novel idea at its time, which brought success to company, since conceived and implemented. It remains live as long as it serves an existing, enduring, and perhaps expanding need (e.g. in other countries like China). Mission, however, should be adaptive32―in our opinion―as time goes-by by retaining possibly its core original meaning (e.g. McDonalds), as mission needs change (given new technologies as well company’s greater size and other changing factors).
However, the way LM presents “mission” implies that we have to deal mainly with present (Robbins and Coulter, op. cit., p. 238 [
√ Generic strategies-GS
GS are due to Porter (1980 [
“cost minimization” is a way for this, especially in a slump, as the service price cannot be increased…as mentioned.
√ Differentiation strategy
In shipping, “service differentiation” is not possible (bulk sectors). One opportunity for shipping firms to differentiate their services was safety, but ISM Code legislated by IMO 20 years or so ago (1993; 1998; 2002), was compulsory. Nevertheless, shipping companies can boost their reputation by announcing company’s records for (few or zero) marine accidents and for (low) average age of ships-owned, list of (major) charterers and an improved public image. But all these do not gain a higher price.
Certain authors believe that the 3rd global revolution is “nonlinear” management (Peters, 1994, [
In nonlinear34 management, an “internal analysis” is also recommended, but based on changes in firm’s conditions. Interesting is to see whether company’s strengths and weaknesses showed an improvement. If the answer is positive, then these should be made strategic advantages. “Nonlinear management strategies” are also plans, for company’s macro future, and for strategies, which determine company’s mission35, and positioning36 (relatively to its competitors); strategies are then selected and implemented (throughout the company).
The main NLMS targets are: to “compete”, “survive” and “grow”, by realizing in depth, company’s business environment [
NLMS deal with company’s changes occurred in recent past (last 4 years, but not exclusively) using trajectories that―come from the past―and have to be followed in future, using a nonlinear tool: the full “Cartesian” diagram. This is a mathematical space, which accommodates yesterday, today and tomorrow…and where company is planning to achieve a vision.
√ The case―study of “Toro Corporation” (USA).
Toro38 Corporation’s actual changes in sales and in profits over 4 quarters (1979-1980) are presented, and connected with their trajectories (

In the horizontal axis we measured changes in company’s sales and in vertical axis changes in earnings per share, for the last 48 months of company’s businesses43; it shows also that the company found itself, at the end of the period, in quadrant Q3, where both changes in sales and changes in earnings…fell.
The pattern of this company shows 8-period trajectories―which means high- order chaos… The company indeed faced a turbulent external environment; and its management’s decisions made apparently without knowledge of the structural patterns of change bound the company. The company had to reduce company’s chaos from an 8-period cycle to a 4―one to begin with. This would be done if company’s trajectory visited one combination of visits in 1,4,2,3 quadrants, and in that order44 or in 2,4,3,1. Here the total combinations are not 2, but 16 (42).

√ Span of management and span of control
Management in shipping is done by distance―as mentioned―and a shipping
manager always wonders whether his/her “span of control―SC” is proper vis-à-vis company’s “span of management” and growth strategy. The dilemma for a shipping manager is: “how many ships should I control”? The “Span of control” is the number of captains a manager can efficiently and effectively manage. This obviously differs from manager to manager and this is the reason for different performances among shipping companies.
The concept of “span of management-SM” is simply the number of (existing) ships to a manager. A small SM means that ships/captains are more closely supervised, and thus they have less decision-making authority―perhaps to their dissatisfaction48. So a shipping manager may consider to delegate more decision- making to his/her captains. An improved SM―qualitatively―obviously can be done through M.HRM―“marine human resources management” for selecting the best available captains, doing their job with minimum supervision.
When we transfer these concepts to company’s office, the larger SM makes a shipping company flatter, and permits also a faster decision-making―important for shipping companies; the greater simplicity in shipping companies achieved also by computers.
Interesting is to present the two concepts together (
Let a shipping manager finds his/her company to have a relationship between “span of management” and “span of control” denoted by B. At B, the number of captains/ships increased, perhaps due to growth strategy by building or buying ships; but the ability of the manager to control them declined. This leads to inefficiency. Moving to D, the manager improved his/her span of control, but this might be done because the number of captains/ships reduced, as perhaps a number of ships sold. At C both controls decline. As a result A, where a shipping
company’s span of management and span of control increase proportionally, is the desirable one (at a 45˚ degrees trajectory).
As Lorange (2009 [
We have met Greek shipowners that the right span of control over their captains and engineers allowed them to be small (say 5 - 10 ships). Other, manage ships of a great number of ships (= 39 in May 2009) and tonnage… (e.g. “The namaris ship management Inc.” www.thenamaris.com).
・ Paper’s main contributions
The paper has tried to provide a concise presentation of two qualitatively different approaches to managing companies, as well as managing shipping companies. The reader who knows linear management may benefit from the nonlinear management analysis provided, who we presumed he/she ignores. Our opinion of course is to replace linear management by nonlinear one, but this would be neither wise nor acceptable. Every manager should ask we believe: “is business world nonlinear?”
Moreover, we showed the crucial issues that a shipping company faces, in order of importance, dissolving also some wrong assumptions. We considered that it is important for managers to be able to discover the level of chaos the company they manage faces and thus to rectify its situation. We showed that shipping company “Eletson” embarked wrongly on an extensive shipbuilding program without estimating future freight market―the error was revealed clearly only by nonlinear analysis.
Linear management strategies’ list is a shopping one, (we presented 22), which we believe do not help much shipping managers. Obviously research is unsettled. Moreover, linear theory is not satisfied even with leadership, but it needs now it to be effective. Moreover, a strategy is not a way to make money.
The 1970 “strategic planning model” of general Electric, surely had to change. The order of its steps had to change too: SWOT analysis should be prior to company’s mission. In addition, no company was ever unable to achieve its mission, as in most cases mission is broadly stated (= achievable). Also, internal analysis should be based on changes in organizational conditions. In addition, and more important, company’s vision is absent, and is dependable on leadership, and on a new term of leadership called “effective”, which appeared in 1999.
Nonlinear management is dynamic as it uses changes in variables overtime; it can be used also for “management by visioning”. Moreover, it may indicate the order of chaos. It also indicates where and when management has failed and how far the recent situation is away from the desirable outcome in quadrant 1. Also, it shows which variables have to be improved.
Linear Management has paid attention exclusively on “span of control”, which is more difficult to measure, including the two “confusing” concepts of efficiency and effectiveness. Nonlinear management added “span of management”.
Ten maritime countries and 10 shipping companies adopted the strategy of “maximizing their fleets” (a “growth strategy within the industry” = horizontal) by spending serious amounts to obtain new ships.
The best strategy for shipping is to have a shipping manager―having dexterity in 1st-best timing―who can buy 2 ships… at the price of one…with same money―at different times. This indirectly means to double company’s size using the same capital! Research has found also that the 1st-best timing sale of a ship provides the company with 3 yearly profits from her operations…Here is “all the wisdom about shipping strategies” in one simple strategy: “best timing”.
One condition of “perfect competition” does not hold, as an individual (large) shipping company can influence Supply, as we showed. Thus, competition is valid only in demand’s side.
A final conclusion, which can be drawn, and perhaps is repeated, is that a successful shipping manager has to apply 1st-best timing or even 2nd-best one, at all times and minimizing the costs of the company permanently. The growth strategy―followed by the great majority of shipping companies and the 10 top maritime countries―is recommended, but on the condition that demand is there, through forecasting and by using other people’s money and paying special attention to company’s liquidity. Greeks have adopted a traditional and successful shipping policy so far: buy/order at rock bottom prices, sell smaller and older ships by maintaining or increasing present fleet in the end.
Further ResearchA desirable further research is the one that will combine profits with one appropriate strategy. We repeat the questions posed by Magretta [
Moreover, the more realistic theory of management, i.e. the nonlinear one, has to expand further―since 1992―to reach up the level/volume of linear management. Further research has an extensive horizon to establish management dynamic tools beyond the few we have showed.
In addition, a better forecasting is essential for shipping that as we saw follows the traditional safe way of ordering/buying cheap larger and younger capital goods in a strategic timing together with a strict management of total cost pursuing at the same time economies of scale. This ends to a growth strategy and the creation of competitive advantages: larger size, lower cost, more efficient capital goods etc. And all this without the help of a management theory―linear or nonlinear―but making actions that follow their father’s policy, which has been tested over centuries and proved successful. Further research is called to help shipowners and not live them indifferent.
Surely, we have to start with listed companies that provide transparency and perhaps allow research on their strategies. Secrecy in shipping industry no doubt prevents research and thus management theorists cannot create models and strategies for them.
