ISO 18770:2005 船舶および海洋技術—機械空間の可燃性オイルシステム—可燃性オイルの漏れの防止 | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 18770 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery.

Introduction

Fuel oil, lubricating oil and other flammable oil system failures are a major source of shipboard fires. This International Standard specifies the measures that shall be taken to reduce fires originating from machinery-space flammable oil systems, and is intended for designers, shipyard personnel, engine-room personnel, owners, operators and maintenance personnel. Requirements contained herein address the design, construction, testing, installation, maintenance and inspection of systems containing flammable oils.

It is the intent of this International Standard to supplement and provide guidance in support of the following International Maritime Organization circulars, with the eventual goal of replacing these circulars.

• MSC/Circular 647 (1994), “Guidelines to Minimize Leakages from Flammable Liquid Systems”, a supplement for SOLAS Regulation II/2-15 (“Arrangements for Flammable Oils”). It addresses several aspects of the fuel oil, lubricating oil and other flammable oil systems, such as hoses, spray shields, insulation, connectors, joints and supports.
• MSC/Circular 851 (1998), “Guidelines on Engine-Room Oil Fuel Systems”, a supplement to MSC/Circular 647. This circular addresses causes of oil fuel leakage, which sometimes result in machinery space fires. It discusses design, installation, maintenance and inspection issues, and explains some contributing factors such as frequent dismantling, short-duration pressure pulses, and vibration.

1 Scope

This International Standard specifies the measures to be taken to reduce fires originating from machinery-space flammable oil systems and to prevent leakage of flammable oil. It is intended for designers, shipyard personnel, engine-room personnel, owners, operators and maintenance personnel. Requirements contained herein address the design, construction, testing, installation, maintenance and inspection of systems containing flammable oil.

This International Standard is applicable to new and existing vessels, and is intended to be used as a supplement to the regulations for fuel oil, lubricating oil and other flammable oils contained in the International Convention for the Safety of Life At Sea (SOLAS 74), as amended, issued by the International Maritime Organization (IMO).
