Offshore Fuel Gas Boosting

Project Description

For the development of the Lancaster field on the UK Continental Shelf, Hurricane Energy plc has foreseen an Early Production System consisting of two wells tied back to a FPSO. For this project Bluewater Energy Services converted the existing FPSO Aoku Mizu to meet the new conditions.

One of the packages required was a fuel gas compressor package. This unit takes gas from the crude oil separators and compresses this to a suitable pressure and temperature to enable the gas to be used as fuel gas for the Gas Turbine generators on board the Aoka Mizu.
