The principal maritime nations have the following classification societies: Great Britain ------Lloyd’s Register of shipping France----------Bureau Veritas Germany------Germanischher Lloyd Norway-------Det Norske Veritas Italy------Registro Italiano Navale United States of Amerrica--------American Bureau of Shipping Russia-----Register of Shipping of the USSR Japan----Nippon Kaizi Ngokai These classification societies publish rules and regulations which are principally concerned with the strength of the ship, the provision of adequate equipment, and the reliability of the machinery.Ships may be built in any country to a particular classification society’s rules,and they are not restricted to classification by relevant society of the country where they are built.Classification is not compulsory but the shipowner with an unclassed ship will be required to satisfy governmental regulating bodies that it has sufficient structural strength for assignment of a load line and issue of a safety construction certificate. Only the requirements of Lloyd’s Register of Shipping which is the oldest of the classification societies are dealt with in detail. Founded in 1760 and reconstituded in 1834.Lloyd’s Register was amalgamated with the British Corporation, the only other British classification society in existence at that time, in 1949.Steel ships built in accordance with Lloyd’s Register rules or equivalent standards, are assigned a class in the Register Book, and continue to be classed so long as they are maintained in accordance with the Rules. Lloyd’s register classification symbols Class 100A1 is assigned to sea-going ships built in accordance with the society’s rules and regulations for the desired draft. It is also assigned to ships designed for specific purposes, the specific purpose being noted, e.g.100A1 oil tanker,100A1 liquefied gas carrier,100A1 ore carrier,100A1 trawler,100A1 tug, etc. There is also a class 100A1 for restricted service or for special purposes, this class being assigned to sea-going ships intended to operate with specific geographical limits or for special purposes which will be indicated in the Register Book. Additionally there is a class. Al for registered office; this class is intended for ships trading only within specially sheltered waters such as harbours, rivers, etc., which will be indicated in the Register Book. Other class notations noted in the Register Book include :special cargoes, where the vessel has been approved for carrying cargoes, where a special nature; special features, where a special feature in design or construction or machinery, has been approved; corrosion control, where an approved method of corrosion control has been fitted, and a reduction in scantlings has been permitted. Four classes of ice strengthening are detailed in the Rules, and it is the
esponsibility of the shipowner to determine which notation is most suitable for his requirements Ice Class I intended for ships navigating in extreme ice conditions Ice Class 2 intended for ships navigating in severe ice conditions Ice Class 2 intended for ships navigating in intermediate ice conditions Ice Class 3 intended for ships navigating in light ice conditions The figure I in the character of classification assigned to a ship indicates that her equipment of anchors, chain cables, and hawsers are in good and efficient condition and in accordance with the equirements of the Rules. When the equipment is not in accordance with the requirements of the Rules, but is considered by the society to be acceptable for the particular service, they may agree to the figure I being omitted and a line inserted after the character, thus 100A---Special consideration is also given to ships which by reason of their particular service or purpose do not require normal equipment: in this case the figure I may be omitted from the character of lassification. thus 100A Where the machinery in constructed and installed on board the ship in accordance with the Societys Rules and regulations, on satisfactory completion of trials the machinery is assigned the notation LMC(Lloyds Machinery Certificate)in the Register Book New vessels built for classification with Lloyd's Register are to have all constructional plans and particulars of the hull, equipment, and machinery submitted to the Society for approval before the work is commenced. These vessels are built under the Society's Special Survey which entails the presence of the local surveyor, from work commencement to ship completion, to examine the material and workmanship. When classed the vessel will be entitled to the distinguishing sed the vessel will be entitled to the distinguishing mark t indicating it is built under Special Survey inserted before the character in the Register Book, thus t 100AL. New machinery constructed under the Society's Special Survey is given the class notation in the Register Book + LMC.The date of completion of the special survey during construction will normally be taken as the date of build entered in the Register Book Periodical surveys To maintain the assigned class the vessel has to be examined by the Societys surveyors at regular periods nnual suney All steel ship are required to be surveyed at intervals of approximately one year. These annual surveys are where practicable held concurrently with statutory annual o other load line surveys. At the survey the survey is to examine the condition of all closing appliances covered by the conditions of assignment of minimum freeboard, the freeboard marks, and auxiliary steering gear particularly rod and chain gear. At the second annual survey on cargo ships or the third and subsequent special surveys on oil tankers an after and a forward hold or tank are to be examined internally Docking surveys A ship is required to be examined in dry clock at intervals of about 12 months, the maximum interval allowed being two years. At the clocking survey particular attention is paid to the shell plating, stern frame and rudder, and all parts of the structure particularly liable to corrosion and chafing, and any unfairness of bottom The general condition of the vessel is assessed, and anchors and cables are inspected where possible at these annual and docking surveys sun Special surveys All steel ships classed with Lloyds Register are subjected to special veys.

When the equipment is not in accordance with the requirements of the Rules, but is considered by the society to be acceptable for the particular service, they may agree to the figure 1 being omitted and a line inserted after the character, thus 100A----Special consideration is also given to ships which by reason of their particular service or purpose do not require normal equipment: in this case the figure I may be omitted from the character of classification, thus 100A. Where the machinery in constructed and installed on board the ship in accordance with the Society’s Rules and Regulations, on satisfactory completion of trials the machinery is assigned the notation LMC (Lloyd’s Machinery Certificate) in the Register Book. New vessels built for classification with Lloyd’s Register are to have all constructional plans and particulars of the hull, equipment, and machinery submitted to the Society for approval before the work is commenced. These vessels are built under the Society’s Special Survey which entails the presence of the local surveyor, from work commencement to ship completion, to examine the material and workmanship. When classed the vessel will be entitled to the distinguishing sed the vessel will be entitled to the distinguishing mark ╋ indicating it is built under Special Survey inserted before the character in the Register Book, thus ╋ 100AL.New machinery constructed under the Society’s Special Survey is given the class notation in the Register Book ╋ LMC. The date of completion of the special survey during construction will normally be taken as the date of build entered in the Register Book. Periodical surveys To maintain the assigned class the vessel has to be examined by the Society’s surveyors at regular periods. Annual surveys All steel ship are required to be surveyed at intervals of approximately one year. These annual surveys are where practicable held concurrently with statutory annual or other load line surveys. At the survey the survey is to examine the condition of all closing appliances covered by the conditions of assignment of minimum freeboard, the freeboard marks, and auxiliary steering gear particularly rod and chain gear. At the second annual survey on cargo ships or the third and subsequent special surveys on oil tankers an after and a forward hold or tank are to be examined internally. Docking surveys A ship is required to be examined in dry clock at intervals of about 12 months, the maximum interval allowed being two years. At the clocking survey particular attention is paid to the shell plating, stern frame and rudder, and all parts of the structure particularly liable to corrosion and chafing, and any unfairness of bottom. The general condition of the vessel is assessed, and anchors and cables are inspected where possible at these annual and docking surveys. Special surveys All steel ships classed with Lloyd’s Register are subjected to special surveys. These surveys become due at four –yearly intervals, the first four years from the date of
build or date of special survey for classification and thereafter four years from the date of the ial survey. Where it is inconvenient for the owner to fulfil this requirement Lioyds will allow a period of grace not exceeding twelve months from the due date providing the surveyor is able to asses the general condition of the vessel about the time of the due date. Special surveys may, where the vessel is on a regular schedule, be carried out over an extended period and be commenced prior to the due date, but should not extend over a period greater than twelve months At the request of an owner, Lloyds Register may agree to the survey of a hull being carried out on a continuous survey basis, all compartments of the hull being opened up for survey and testing in rotation, with an interval of five years between consecutive examinations of each part The hull requirements at a special survey, the details of the compartments to be opened up, and the material to be inspected at any special survey are listed in detail in the rule book( Chapter C. Section 2--cargo Ships, Section 3-Oil Tankers ) Special survey hull requirements are divided into four ship age groups as follows A-Special survey of ships under five years old B--Special survey of ships between five and ten years old C-Special survey of ships over ten years old D-First special survey held after ship is twenty years old and at every special survey thereafter In each case the amount of inspection required increases and more material is removed so that the condition of the bare steel may be assessed. It should be noted that where the surveyor is allowed to ascertain by drilling or other approval means the thickness of material, non-destructive methods such as ultrasonics are available in contemporary practice for this purpose When classification is required for a ship not built under the supervision of the Society's surveyors, plans showing the main scantlings and arrangements of the actual ship are submitted to the Society for approval. Also supplied are particulars of the manufacture and testing of the materials of construction, together with full details of the equipment. Where plans etc, are not available, the Society's surveyors are to be allowed to lift the relevant for classification all the hull quirements for special surveys(A), (B), and (c)are to be carried out. Ships over twenty years old are to comply with the hull requirements of special survey(D), and oil tankers must comply with the additional requirements stipulated in the rules and regulations. During this survey the surveyor assesses the standard of the workmanship, and varies the scantlings and arrangements submitted for approval. It should be noted that the special survey for classification will receive special consideration from Lloyd's Register in the case of a vessel of reasonably new construction Periodical surveys where the vessel is classed are subsequently held as in the case of ships built under survey, being dated from the date of special survey for classification When a vessel requires repairs to damaged equipment or to the hull it is necessary for the work to be carried out to the satisfaction of Lloyds Register surveyors. In order that ship maintains its class, approval of the repairs undertaken must be obtained from the surveyors either at the time of the repair or at the earliest opportunity hip Construction"by D J Eyres, 1972)

Where it is inconvenient for the owner to fulfil this requirement Lioyd’s will allow a period of grace not exceeding twelve months from the due date providing the surveyor is able to asses the general condition of the vessel about the time of the due date. Special surveys may, where the vessel is on a regular schedule, be carried out over an extended period, and be commenced prior to the due date, but should not extend over a period greater than twelve months. At the request of an owner, Lloyd’s Register may agree to the survey of a hull being carried out on a continuous survey basis, all compartments of the hull being opened up for survey and testing in rotation, with an interval of five years between consecutive examinations of each part. The hull requirements at a special survey, the details of the compartments to be opened up, and the material to be inspected at any special survey are listed in detail in the Rule Book (Chapter C. Section 2---cargo Ships, Section 3—Oil Tankers ). Special survey hull requirements are divided into four ship age groups as follows: A— Special survey of ships under five years old B—Special survey of ships between five and ten years old C—Special survey of ships over ten years old D— First special survey held after ship is twenty years old and at every special survey thereafter. In each case the amount of inspection required increases and more material is removed so that the condition of the bare steel may be assessed. It should be noted that where the surveyor is allowed to ascertain by drilling or other approval means the thickness of material, non-destructive methods such as ultrasonics are available in contemporary practice for this purpose.

Where plans etc., are not available, the Society’s surveyors are to be allowed to lift the relevant for classification all the hull requirements for special surveys (A), (B), and (C) are to be carried out. Ships over twenty years old are to comply with the hull requirements of special survey (D), and oil tankers must comply with the additional requirements stipulated in the Rules and Regulations. During this survey the surveyor assesses the standard of the workmanship, and varies the scantlings and arrangements submitted for approval. It should be noted that the special survey for classification will recelve special consideration from Lloyd’s Register in the case of a vessel of reasonably new construction. Periodical surveys where the vessel is classed are subsequently held as in the case of ships built under survey, being dated from the date of special survey for classification. Damage repairs When a vessel requires repairs to damaged equipment or to the hull it is necessary for the work to be carried out to the satisfaction of Lloyd’s Register surveyors. In order that ship maintains its class, approval of the repairs undertaken must be obtained from the surveyors either at the time of the repair or at the earliest opportunity.
