DeploymentBlock 21/30 Triton field The FPSO Triton moored here since Mar 2000, takes reservoir fluids from a number of fields (including Bittern and Guillemot West). The gas is sent to St Fergus via a 10 inch spur from the Fulmar Gas Line and oil is shuttled away by tanker from the FPSO. First oil was from the Bittern Field in Apr 2000.
