Cygnus gas facility

Japan-based Yokogawa Electric said that its subsidiary Yokogawa Europe Solutions has secured a contract, from GDF SUEZ E&P UK, to deliver the integrated control and safety systems (ICSS ) for the new Cygnus Development Project in the North Sea, UK.

As part of the contract the company will deliver the entire ICSS package, including process control, process shutdown, emergency shutdown, process data historian, field device asset management and fire and gas detection, along with its associated field devices.

The system will offer integrated and flawless control and safety functions for the platforms, while it will provide operators with a single interface to start, control and monitor all facilities from a central control room.

The company will also supply an operator training system (OTS ), which will use the OmegaLand advanced operator simulation environment.

In addition, the ICSS will include the CENTUM VP process automation system, ProSafe-RS safety system, Exaquantum production management solution and PRM asset management package.

The PRM package is understood to reduce maintenance costs and facilitate proactive instrument maintenance management, while the OTS will be used for operator training, as well as an engineering tool to confirm changes in control strategy.

"The system will offer integrated and flawless control and safety functions for the platforms."

Yokogawa will install the ICSS across the Cygnus facility, which currently includes four greenfield offshore platforms – Alpha WHP, PU , UQ and Bravo WHP. Except for Bravo WHP, where a second remote drilling centre is located, all the remaining platforms are bridge linked.

Gas from the facility will be exported through the ETS pipeline system to the Perenco Bacton Gas Terminal in north Norfolk, according to Yokogawa.

Located within UK Continental Shelf blocks 44/12a and 44/11a, the Cygnus gas field is expected to contain 18 billion cubic metres in proven and probable reserves.

GDF SUEZ is the operator of the field, holding 38.75% interest, while Centrica and Bayerngas are the remaining partners, owning 48.75% and 12.5% respectively.

Once the gas field begins production by the end of 2015, it is expected to meet demand for around one and a half million homes during peak production, accounting for around five percent of the UK’s total gas production.
