Rule Changes By

Lloyd's Register

The Technical Committee of

Lloyd's Register of Shipping has approved new Rules for Inwater

Surveys and a number of additions and amendments to the Rules for the Construction and Classification of Steel Ships, subject to confirma- tion by the General Committee.

Rules for Inwater Surveys—

These new Rules are intended to permit owners of large vessels to obtain exemption from certain docking surveys on ships in good condition. The Rules are applicable to ships of a suitable design which are properly marked with some sort of reference grid to enable under- water surveys to be effectively un- dertaken. The Rules also provide for the approval by Lloyd's Regis- ter of appropriately qualified firms capable of carrying out underwater surveys under the supervision of

Lloyd's Register surveyors.

Longitudinal Strength of Ships—

A reduction in the hull modulus re- quirements for oil tankers and for ships intended for the carriage of ore or other heavy cargoes has been agreed. The strength standards as applied to ordinary cargoships may be used, provided that specific care is exercised to ensure that panel stability against buckling is main- tained at a satisfactory level.

Movable Decks on Ferries and

Car Carriers—Owners are now per- mitted to apply for the class nota- tion "Movable Decks" to be grant- ed for ships on which all movable decks, including vehicle ramps and their stowage arrangements, com- ply with Lloyd's Register's pub- lished Rules. Such a notation will be of particular benefit to owners of ships who are required to com- ply with the recently enacted Nor- wegian regulations for movable decks.

The Diameter of Certain Ma- chinery Shafts—Amendments have been made to the diameters at present required for certain items of line shafting which are based on the diameter required for the inter- mediate shaft, with a view to achieving a unified approach by all the major classification societies.

Inert Gas Systems on Tankers—

The requirements have been amend- ed taking into account comments which have been received from in- dustry regarding the construction and,operation of these plants. The amendments also take into account the acceptance of the gas turbine as a source of inert gas supply, the draft IMCO regulations for inert gas systems and the proposed amendments to the IACS unified requirements for inert gas systems.

Requirements for Hull Structural

Steels—Some amendments have been made, principally to achieve alignment with the proposed IACS revisions to the unified require- ments for mild steels and to the agreed IACS requirements for high- er tensile steels.
