General Never continue to operate any machine or equipment which appears to be potentially unsafe or dangerous and always report such a condition immediately Although the ship is supplied with shipbuilder's plans and manufacturer’s instruction books, there is no single handbook which gives guidance on operating complete systems as installed on board, as distinct from individual items of machinery Make a point of testing all safety equipment and devices regularly Always test safety trips before starting any equipment In particular, overspeed trips on auxiliary turbines must be tested before putting the unit into operation The purpose of this manual is to fill some of the gaps and to provide the ship’s officers with additional information not otherwise available on board It is intended to be used in conjunction with the other plans and instruction books already on board and in no way replaces or supersedes them Never ignore any unusual or suspicious circumstances, no matter how trivial Small symptoms often appear before a major failure occurs INTRODUCTION Information pertinent to the operation of the vessel has been carefully collated in relation to the systems of the vessel and is presented in three on board volumes consisting of CARGO and DECK OPERATING MANUAL and MACHINERY OPERATING MANUAL and BRIDGE OPERATING MANUAL The Cargo Operating Manual and the Machinery Operating Manual are designed to complement MARPOL 73/78, ISGOTT and Company Regulations The vessel is constructed to comply with MARPOL 73/78 These regulations can be found in the Consolidated Edition, 1991 and in the Amendments dated 1992, 1994 and 1995 Officers should familiarise themselves with the contents of the International Convention for the Prevention of Pollution from Ships Never underestimate the fire hazard of petroleum products, whether fuel oil or cargo vapour In the design of equipment and machinery, devices are included to ensure that, as far as possible, in the event of a fault occurring, whether on the part of the equipment or the operator, the equipment concerned will cease to function without danger to personnel or damage to the machine If these safety devices are neglected, the operation of any machine is potentially dangerous Description The concept of this Operating Manual is based on the presentation of operating procedures in the form of one general sequential chart (algorithm) which gives a step-by-step procedure for performing operations Particular attention is drawn to Appendix IV of MARPOL 73/78, the form of Ballast Record Book It is essential that a record of relevant ballast operations are kept in the Ballast Record Book and duly signed by the officer in charge The manual consists of introductory sections which describe the systems and equipment fitted and their method of operation related to a schematic diagram where applicable This is then followed where required by detailed operating procedures for the system or equipment involved In many cases the best operating practice can only be learned by experience Where the information in this manual is found to be inadequate or incorrect, details should be sent to the British Gas Shipping Technical Operations Office so that revisions may be made to manuals of other ships of the same class Each operation consists of a detailed introductory section which describes the objectives and methods of performing the operation related to the appropriate flow sheet which shows pipelines in use and directions of flow within the pipelines Safe Operation Details of valves which are OPEN during the different operations are provided in-text for reference The safety of the ship depends on the care and attention of all on board Most safety precautions are a matter of common sense and good housekeeping and are detailed in the various manuals available onboard However, records show that even experienced operators sometimes neglect safety precautions through over-familiarity and the following basic rules must be remembered at all times Issue: Final Draft Cargo and Deck Operating Manual Illustrations All illustrations are referred to in the text and are located either in-text where sufficiently small or above the text, so that both the text and illustration are accessible when the manual is laid face up When text concerning an illustration covers several pages the illustration is duplicated above each page of text Where flows are detailed in an illustration these are shown in colour A key of all colours and line styles used in an illustration is provided on the illustration Details of colour coding used in the illustrations are given in the colour scheme Symbols given in the manual adhere to international standards and keys to the symbols used throughout the manual are given on the following pages Notices The following notices occur throughout this manual: WARNING Warnings are given to draw reader’s attention to operations where DANGER TO LIFE OR LIMB MAY OCCUR CAUTION Cautions are given to draw reader’s attention to operations where DAMAGE TO EQUIPMENT MAY OCCUR Note: Notes are given to draw the reader’s attention to points of interest or to supply supplementary information Safety Notice It has been recorded by International Accident Investigation Commissions that a disproportionate number of deaths and serious injuries that occur on ships each year during drills involve lifesaving craft It is therefore essential that all officers and crew make themselves fully conversant with the launching, retrieval and the safe operation of the lifeboats, liferafts and rescue boats The valves’ and fittings’ identifications used in this manual are the same as those used by British Gas Shipping Front Matter - Page of
