General 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 distinct from individual items of machinery 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 In addition to containing detailed information of the Machinery and related systems, the machinery manual provided by each vendor, contains safety procedures, and procedures to be observed in emergencies and after accidents Used in conjunction with the EXMAR SMS MANUAL, this information is designed to ensure the safety and efficient operation of the ships Quick reference to the relevant information is assisted by division of the manual into Parts and Sections, detailed in the general list of contents on the preceding pages Reference is made in this book to appropriate plans or instruction books For other information refer to: 1) Books and Publications contained in the SMS Directory Cargo Operating Manual 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 Never ignore any unusual or suspicious circumstances, no matter how trivial Small symptoms often appear before a major failure occurs Never underestimate the fire hazard of petroleum products, whether fuel oil or cargo vapour Never start a machine remotely from the control room without checking visually if the machine is able to operate satisfactorily 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 Cargo 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 2) SMS MANUAL In many cases the best operating practice can only be learnt by experience Where the information in this manual is found to be inadequate or incorrect, details should be sent Hull Piping Design Team of DSME so that revisions may be made to manuals of other ships of the same class Safe Operation 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 overfamiliarity and the following basic rules must be remembered at all times Never continue to operate any machine or equipment which appears to be potentially unsafe or dangerous and always report such a condition immediately 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 The overview of machinery operations, consists of a basic operating algorithm which sets out the procedure for operations from preparing the plant for operation from dead ship condition, to shutting down the plant in readiness for dry dock The relevant Illustration and operation section number is located on the right hand side of each box Each machinery 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 Details of valves which are OPEN during the different operations are provided in-text for reference The ‘valves’ and ‘fittings’ identifications used in this manual are the same as those used by EXMAR of 245 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 operation where danger to life or limb may occur ! Caution Cautions are given to draw reader’s attention to operations where danger to life or limb may occur Note ! Notes are given to draw reader’s attention to points of interest or to supply supplementary information ...LNGC EXCALIBUR Cargo Operating Manual 4.3 Cargo Pumps 83 4.3.1 Main Cargo Pumps 85 4.3.2 Stripping/Spray Pumps 87 4.3.3 Emergency Cargo. ..
