Neptune platform co-mingled fluids are transported to a dedicated riser tower on the Cleeton installation via a 16-inch diameter pipeline. The gas is separated, dried and metered on Cleeton before transmission into the BP Cleeton/Dimlington pipeline system. A contract for the pipelines and subsea facilities, valued at around £23m, was awarded to ETPM UK. Methanol for hydrate formation inhibition is piped from Cleeton to the Neptune platform. First gas was produced in 1999.

pipeline to the
Minerva platform. Produced fluids from all three fields are co-mingled on the Minerva platform, and the combined flow exported via a 16-inch diameter pipeline to the BG-operated ECA riser tower bridge-linked to the Cleeton complex. The Wollaston and Whittle fields are developed via subsea wells and flowlines tied back via a manifold and a 12-inch diameter pipeline to the ECA riser tower, where they are co-mingled with the Minerva hub fluids. The first gas from the second phase was produced in 2003.

The
Neptune field was developed using three new wells, an existing well and a new NUI (normally unattended installation). The Mercury field was developed with a subsea installation with well fluids produced to the Neptune NUI via a 10-inch diameter pipeline. The Neptune platform consists of a 630

The
Easington Catchment Area project was developed in two phases. The £150 million first phase involved development of the Mercury (Block 47/9b) and Neptune (Blocks 47/4b and 47/5a) gas fields which had been discovered in 1983 and 1985 respectively. The ECA partners were, for the Neptune field:

The
Minerva hub facilities consist of subsea production systems on Apollo and Artemis and a normally unattended installation (NUI) at Minerva. The Apollo subsea wells are tied back via a manifold and pipeline to the Minerva platform. The Artemis appraisal well is also tied back via a separate

The £270 million second phase of the ECA project, known as Juno, included the development of the Apollo (Block 47/4a), Artemis (Block 47/3), Minerva (Block 47/3), Whittle (Block 42/28b) and
Wollaston (Block 42/28) gas fields. The majority stakeholder for the Juno fields was the
