Chapter 1.3.10

Chapter 1.3.10 reads as follows:

  Marine diesel engine means any reciprocating internal-combustion engine operating on liquid or dual fuel, to which regulations 5, 6 and 13 of Annex VI apply, including booster/compound systems if applied.

Interpretation:

 Regulation 13 does apply to dual-fuel engines. For the application of this section it should be interpreted that if the engine is intended to be operated normally in the gas mode i.e. with the main fuel gas and only a small amount of liquid pilot fuel, the requirements of regulation 13 have to be met only for this operation mode. Operation on pure liquid fuel resulting from restricted gas supply in cases of failures should be exempted for the voyage to the next appropriate port for the repair of the failure.
