History Leading to the 1969 Load Line Conventon

In one of the previous articles we have given some brief Introduction to the Load Lines and Conditions of the Load Line Assignment. As we all know, the assignment of the shipboard load lines and associated requirements are listed in the International Convention on Load Lines of 1969. Today, let us check what were the changes and developments that eventually led to the need for the subject governing document.

Need for a Standardized System

The need for a standardized international system of tonnage measurement of ships is evidenced by the fact that small ships of identical size and form may measure less than 200 gross tons or more than 1000 gross tons and the fact that exemptible and deductible spaces are treated differently under various national rules. The variations in tonnages cause inequities in the assessment of charges and in the application of provisions of treaties and laws.

This need for a standardized system was recognized in tin initiation of the League of Nations study and in the Oslo Convention. History Leading to the 1969 Load Line Conventon - 2However, there were many differences in national systems and in those systems evolving from tin foregoing international activities that were yet to be resolved.

Work by the Intergovernmental Maritime Consultative Organization

In the meantime, the question of tonnage measurement had often been discussed by the Transport and Communications Commission of the United Nations. After the Intergovernmental Maritime Consultative Organization (IMCO) came into being in 1958, the task of developing a universal system of tonnage measurement of ships was taken over by the Organization as the United Nations had intended.

Against this background, IMCO formed a subcommittee of its Maritime Safety Committee in 1959 to study the problem and to draw up recommendations for a system of tonnage measurement suitable for worldwide application, which would be just and equitable between the individual ships and groups of ships, and would not hamper good design or mitigate seaworthiness, and which would take account of the economics of the shipping industry generally.

Over a period of years, the Subcommittee and its working group considered a number of proposals for a universal system of tonnage measurement. Finally the International Conference on Tonnage Measurement of Ships, 19G6, was held in London during a History Leading to the 1969 Load Line Conventon - 3four-week period beginning May 27, 1969.

The Conference adopted the International Convention on Tonnage Measurement of Ships (ICTM, 1969), which the delegations felt largely met the above-listed criteria for a satisfactory system.

Tonnage Measurement - Historical Background

Tonnage measurement rules generally are spelled out in great detail in national laws. More detailed criteria for application of the laws are spelled out in regulations. The laws and regulations are interpreted by administrations established for the purpose. Since tonnages are used to determine the applicability of provisions of treaties, laws, and regulations and as bases for assessing charges, fees, and duties, any change in rules that would result in substantially different tonnage assignments for many vessels would disrupt the shipping industry. Historically, administrative decisions and rule changes have favored the ship owner, probably, because other segments of the shipping industry can protect their individual interests merely by changing rates for charges or by adopting parameters other than tonnages.

Transition from Deadweight to Volumetric Tonnage

The use of one half the breadth for the draft in the formula for approximating deadweight in the system preceding the Moorsom system led owners to acquire vessels that were poorly designed to obtain official tonnage assignments that were making the register tonnage a simple function of the volume of a vessel, the British opted for a coefficient (1/100) that would, on the average, slightly reduce the existing tonnages instead of opting for a coefficient that would more precisely approximate the deadweight.

The reasoning apparently was that if a system yielding higher, more precise deadweight tonnages were adopted, ship owners would find them burdened with higher bases for being assessed charges with no assurance that charging authorities would correspondingly reduce their rates. Other governments in amending their laws followed the example set by England. While the philosophy of avoiding radical changes in the tonnages assigned merchant vessels continues, governments can be persuaded to Tonnage Measurement - Historical Background - 2make their rules more logical.

In seeking a universal tonnage measurement system, the International Conference on Tonnage Measurement held in London in 1969 decided to do away with the system of exemptions and deductions from gross tonnage. The conference adopted a formula that would yield gross tonnages closely approximating those of vessels measured under present national rules without exemptions for shelter 'tween decks, deck spaces opened by tonnage openings, passenger spaces, and water-ballast spaces. On the other hand, the conference decided to maintain the net tonnage advantage enjoyed by shelter deck types and to extend that advantage to other types of vessels having low draft to depth ratios. That decision has already caused some charging authorities to shift their charge bases from net tonnage to gross tonnage.

Resistance to Illogical Changes

With varying degrees of success, governments have, at times, resisted illogical rule changes forced upon or willingly adopted by administrations of other governments. National rules usually provide that a space outside the double bottom adapted only to carry water ballast shall be included in the gross tonnage and deducted to arrive at net tonnage. They also provide that a space above deck shall be included in the gross tonnage if it is closed in and is available for the carriage of cargo or stores or for the berthing or accommodation of passengers or crew.

The United States adopted the Moorsom system by an Act of Congress dated May 6, 1864. That act specifically required passenger spaces to be included in the register tonnage. By an act dated February 28, 1865, however, the U.S. provided for the exemption of passenger spaces on or above the first deck which is not a deck to the hull. Only Liberia and Panama have followed that example. Pursuant to a law enacted February 6, 1909, until 1915 the U.S. included in the gross tonnage then deducted to arrive at net tonnage space adapted only for carrying water ballast out¬side the double bottom.
