HESS Triton Support


Project overview:

Triton is a floating production, storage and offloading vessel (FPSO) that services the oil & gas fields of the Bittern and Guillemot areas.

The Guillemot area consists of the Guillemot West, Guillemot North West, Clapham, Pict and Saxon fields. Dana is the operator of the fields in the Guillemot West area and the Bittern area is operated by Shell. All fields are developed on a sub-sea basis and controlled remotely from Triton.

Triton Field Layout

The fields produce oil & gas through sub-sea manifolds tied back to Triton. The Triton FPSO provides primary separation facilities through two dedicated trains (one for the Bittern area and one for the Guillemot West area) for the separation of oil, gas and water.  Following primary separation and metering, the fluids are commingled and then are subject to secondary separation, oil processing, gas processing and compression through shared facilities. Produced water handling is provided through two new water treatment trains provided to ensure OSPAR compliance, one for the Bittern area and one for the Guillemot West area. The gas is processed to meet the SEGAL entry specification (see SEGAL link below) and two gas compressors provide gas for fuel, gas lift and gas export. Water injection services are also provided.

Petrex scope:

Petrex personnel deployed to support the subsea engineering function as well as the daily operation of the asset by acting as the contractor interface/liaison to the Hess Subsea Lead and Production Group.
