General
The present edition of the rules includes additions and amendments decided by the Board as of November 2004, and supersedes the Janu-ary 2003 edition of the same chapter.
The rule changes come into force on 1 July 2005.
This chapter is valid until superseded by a revised chapter. Supple-ments will not be issued except for an updated list of minor amend-ments and corrections presented in Pt.0 Ch.1 Sec.3. Pt.0 Ch.1 is normally revised in January and July each year.
Revised chapters will be forwarded to all subscribers to the rules.Buyers of reprints are advised to check the updated list of rule chap-ters printed Pt.0 Ch.1 Sec.1 to ensure that the chapter is current.
Main changes
•General
This chapter has been amended in order to align with the following IACS requirements:
—Strength analysis shall be carried out, to confirm sufficient con-structive strength of high pressure gas piping systems.
—All valves and expansion joints used in high pressure gas systems
shall be of an approved type.
—If a duct contains high pressure gas pipes, the ventilation inlet
shall be provided with a non-return device. However, if a gas de-tector is fitted at the air intake, this requirement can be dispensed with.
—Automatic purging of the pipe between the master gas valve and
the engine, when the inner pipe contains high pressure gas.•
Sec.3 Arrangement and System Design
—The general B/5 rule requirement for gas bunker tanks is consid-ered to be too strict for some ship types. The requirements have therefore been amended so that tank location closer than B/5from the ship side may be accepted based on DNV approval on a case by case basis. Passenger vessels are not included and the B/5 requirement has been retained.•
Sec.6 Control, Monitoring and Safety Systems
—The rules for diesel engines have a lower limit (cylinder diameter
200 mm) for when crankcase monitoring is required, and this has been found relevant also for gas engines. Table B2 has been amended accordingly.
Corrections and Clarifications
In addition to the above stated rule requirements, a number of correc-tions and clarifications have been made in the existing rule text.
