This guideline applies to all hydrocarbon processing or production or storage facilities offshore (hereafter call Facilities). The main fixed systems dealt with in this guideline are as follows:? Deluges? Sprinklers systems? Monitors? Foam System? Hydrants? Hose reels1 REFERENCE DOCUMENTS.

Coupling Guard : Brass DriversThe fire pumps can be driven by electrical motors, electrohydraulic motors, electric motors fed by a dedicated diesel generator, or diesel engines.The diesel engines should be capable of being readily started in its cold condition down to a temperature of 00C. Consideration should be given to the provision and maintenance of heating arrangements, so that ready starting will be assured. Diesel EngineThe engine should be a medium speed design and a type selected for reliable starting and immediate acceptance of full load without warm up. Naturally aspirated engine types are required unless otherwise agreed to by COMPANY. Listed engines should be used wherever possible.10 / 32In special cases where the engine is outside the power range and/or type of Listed Engines, the additional power requirements of NFPA20 Para should be applied. Engines should be derated for site elevation and temperature. The VENDOR should advise the site rated power for:a) 4 hours continuous load (NFPA 20)b) 8 hours continuous loadTwo independent engine starting systems by starting batteries, independent hydraulic system, or independent starting air system should be provided in accordance with NFPA20, pl
