SHIPBUILDING


to in afregister boolc of the date 178-1, but there are evidences that in 1768 repairs. were superintended by officers of the society. In 1799 surveyors were stationed at twenty-four ports in the United Kingdom. ln' 1822 the register for the first time recorded a steamship., In 1824 appeared 'the first “ Instructions to Surveyors ” as to the carrying out the rules for classification; and in 1834, on the establishment of the present. society, precise regulations were issued regarding the survey of Steamers. An iron ship was 'built under survey and received a class in 1837, while the first rules for the construction of iron ships were issued in 1855. In 1851 a composite vessel was classed, but it was not until 11867 that rules -for the construction of such vessels were issued. Steel was accepted in 1867, experimentally, steel bein then made by the Bessemer process. Steel by the Siemens-liartin process wasfirst used for two small steamers in 1877. Engineer' -surveyors were first appointed in 1874. The society is voluntarily maintained by the shipping community. Its affairs are managed by a committee of sixt -one members-composed of, merchants, shipowners and unchrrwriters-elected to represent the important shipping centres of the country, and there are branch committees at Liverpool and Glasgow. In technical matters affecting the rules for the construction of ships and machinery the committee has the advantage of the co-operation of a body of representatives of prominent s ipbuilders, engineers, steelmakers and forge masters, who are specially elected by the leading technical institutions of Great Britain. The society's rules for steel ships were entirely revised so recently as 1909. The society has a total stafi, at home and abroad, of 310 surveyors, of whom 232 are its exclusive servants., ;

In the case of a new vessel intended for classification, the plans for its construction are in the first place submitted to and approved by the committee; the building proceeds u-nder the supervision of the local surveyor, and when completed, a character is assigned to the vessel, by the committee upon that surveyor°s report., The society issues annually to its subscribers a register book containing particulars of classification of vessels to which classes have been assigned, together with man other details. All merchant vessels in the world of 100 tons and, upwards, excluding those trading on the Caspian Sea, and wooden vessels on the Great Lakes of North America, are included in the workL This register contains particulars of theiage, build, tonnage, dimensions, ownership, &c., of some 30,000 vessels. The society also publishes yearly a register of yachts, containing full particulars of the yachts of the world and other interesting information, and a register of American yachts, which gives similar particulars of all American and Canadian yachts. All the public proving establishments in the United Kingdom for the testing of anchors and chain cables are licensed by the Board of Trade to carry out these tests under the control of the committee of Lloyd's Register; The assignment of free boards' of vessels, the survey. of refrigerating machinery, electric light installation, &c., all come within the scopeof the societ 's operations. The Bureau Veritas was foundedlin Antwerp in 1828, one of its princi al aims being to make known to underwriters the qualities and tihfects of ships frequenting Dutch and Belgian ports. In 18 2 the headquarters were moved to Paris, and in due time its influence spread to all countries where ship owning or shipbuilding existed; it is now represented in over 250 districts comprising about 1500 ports. In 1851 rules were drawn up for the construction of wood ships, and about.1867 for iron. Rules for steel came later, and also rules for the construction of machinery, and, as circumstances arose, provision was made for special types, such as oil-tank vessels, turret vessels, dredgers, &c., as well as for the testing -of materials. These rules have been revised from time to time and recently have been refnodelled and extended, so as to apply to vessels up to about 900 ft. in length. Special rules have been issued for.vessels intended for navigation in inland waters, for achts and for motor boats. A staff of Surveyors formed part' of the organization- from the 'beginning; and in the earlier days the professional experience of the surveyors was the o'nly guide as to what was necessary and sufficient. With the lapse of time, and with increased variety of construction and complication of interests, something ' more than individual udgment and experience became necessary, and with the Bureau Veritas, as with Lloyd's>and other similar societies, definite rules were introduced, and by their means a greater uniformity of practice was attempted and secured. <-The

British Corporation was founded in 1890, and obtained its charter under the Merchant Shipping Acts for the assignment of free boards; its first rules-were issued in 1893. Its inception was due to the enterprise and inhuence of a number of leading shipowners, shipbuilders and engineers throughout the country, and more particularly in Glasgow and the West of, Scotland, the first aim of the founders being to provide an independent society, thoroughly capable of dealing with the complicated questions which were likely to arise under the Load. Line Act then coming into operation. The Liverpool Registry, which had once been independent, had been absorbed into Lloyd's Register some years before, and it was thought that the, enormous shipbuilding interests of the country demanded the existence of a society whose friendly rivalry with the great society of Lloyd's Register 'would have a beneficial influence on the shipbuilding of the country, Owing to-the comparative absence of small vessels the relatively small number of the vessels on the register represents 2,331,000 tons. The society is controlled by a committee of forty members-shipowners, shipbuilders and underwriters-and, in addition, there is a branch committee in Italy. There is a staff of 135 surveyors distributed over the principal home and foreign ports.-The

Norske Veritas was established in 1864 by the various marine insurance clubs of Norway. Previously each club had its own separate staff of surveyors, on whose report to their club depended the class of the vessel and the premium to be paid. As ships rose in value and reinsurance became the rule, something had to be done for mutual protection. By the establishment of the Norske Veritas one uniform system of classing and valuing was substituted for the older methods. In the matter of rules this society kept pace with the changes of the mercantile marine; it provided, as the occasion required, for the introduction of iron and steel in place of wood, and of steam in place of sails. V

The Gerrnanischer»Lloyd was established in 1867, and reorganized as a joint-stock company in 1889. Its functions are carried out by, officers at the central office in Berlin, assisted by astaff of 50 ship and engine surveyors in Germany and 120 at the principal foreign ports, the latter under control of agents, who are mostly consuls, “ In all foreign parts in which the Gerrnanischer Lloyd has no representative, the German consuls are required by order of their goveénrnent to exercise the functions of an agent of the Germanischer oy . V

The Registro Nazionale Italiano was formed in: 1910 to take over the Registro Italiano, which was founded in 1861. The society has adopted the rules of the British Corporation Registr, has a staff of surveyors in Italy, and has an arrangement with the Biiitish Corporation which enables them to utilize the services of the surveyors to that society in British and foreign ports. i V

The Record of American and, Foreign Shipping, was established in 1867 by the American Shipmasters' Association (now called the American Bureau of Shipping), and is the standard American authority. Its rules for the construction and classification' of vessels, as published in 1889 and amended in 1900, received the approval of the U.S. Navy Department and of the several boards of American underwriters. It has agents and surveyors in many' of the rincipal ports of the world.

The present rules and tables' of most of the above societies apply to construction in steel. Lf iron is to be used in the construction of vessels, the material must be increased in thickness from 10% to 25 %, dependent upon the part for which it is to be used and the quality of the iron. In some cases separate tables for steel and iron accompany the rules, and ina few cases the societies provide rules for construction in wood. Thelatest rules of Lloyd's Register provide only for steel ships, but vessels of wood and iron are still classed, The highest class assigned, upon Completion of a ship by the societies referred to, is as follows:—
