The largest gas discovery in the Southern North Sea in the last 25 years, the Cygnus gas field is expected to contribute five percent of the UK’s total gas production at peak—supplying gas to the equivalent of 1.5 million homes in Britain. In 2012, SNC-Lavalin was awarded a contract by Burntisland Fabrications Ltd. for the detailed design of four jackets for the Cygnus field development. Located at a water depth of about 20 metres, the jackets will support two wellhead platforms, as well as production and living quarters platforms.
Preventing injuries through design
SNC-Lavalin designed-out confined space working during the fabrication phase of the Cygnus jacket’s construction by using single-sided welds where possible. This addressed potential construction safety issues at the design phase, and demonstrates our commitment to safety, one of our company’s most longstanding and fundamental values.
Rising to meet a new challenge
The London offshore engineering office has a strong track record of integrating our project teams, systems and processes with those of partners to successfully deliver a number of offshore substructure EPC projects. This allows SNC-Lavalin to work effectively to deliver to demanding schedules, safely, on time and on budget.
SNC-Lavalin’s successful delivery for the first part of its mandate for Cygnus led to the award of additional scope for the structural detailed design of some of the topsides. This award was direct from the ultimate client, GDF Suez, and included detailed design for four topsides structures: the APU platform flare, BWHP vent and the two Alpha complex bridges. An aggressive schedule has been set to meet fabrication yard priorities.
