Cheviot platform firewater pumps meet class standards

Offshore staff

READING, UK – SPP Pumps has contracted Finning Cat to supply two Cat 3512C HD engines to drive firewater pumps for the Cheviot oil and gas production platform in the UK North Sea.

ATP commissioned the semisubmersible drilling, production, and storage platform, which is due for completion this year.

The Cat marine engines, rated at 1,678 kW at 1,800 rpm, are customized to meet both the client’s specification and requirements of NFPA 20, the National Fire Protection Association standard. This is to ensure that the engines deliver reliable power in the event of a fire emergency.

The engine rating is approved by ABS as required for the floating platform. It meant, however, that Finning had to design the engine package to maintain operation at a constant 22.5° tilt in the event of an emergency, i.e. the platform losing buoyancy. 

Each firewater pump engine is certified to EPA marine tier two classification and meets the E3 emissions’ test cycle for marine applications. Additionally, NFPA requirements specified the addition of a dual engine control module (ECM) – if the main ECM fails, the second module will maintain the engine systems and performance should be unaffected.

The Cheviot platform will be deployed 62 mi (100 km) east of the Shetland Islands, in 550 ft (167 m) of water. It is due to enter service in 2014.
