ABERDEEN, UKApache Corp. has contracted Xodus Group to conduct studies for two subsea tiebacks in the UK central North Sea.

One involves initially a conceptual assessment of options under consideration for the 2016 Storr discovery in the Beryl area before progressing to front-end engineering design (FEED) for the selected option.

The scope includes subsea pipeline design, flow assurance, materials and corrosion engineering coatings selection, and structural and environmental support.

Xodus is also performing subsea engineering for the Seagull oil field, 50 mi (80 km) south of Apache’s Forties complex in block 22/29c, which was reportedly under review for a tieback to the BP-operated ETAP complex.

Previously Xodus completed the concept selection phase for the development. As with Storr, the scope includes pipeline engineering, materials and corrosion support, manifolds and structures engineering, and environmental impact support.

In addition, Woodside Energy has commissioned the company to investigate the topsides design for a redeployed FPSO facility at the Rufisque, Sangomar and Sangomar Deep blocks offshore Senegal.

This award followed earlier field development architecture studies performed by Xodus for Capricorn Senegal, a subsidiary of Cairn Energy, to identify and develop the field architecture for thedeepwater SNE oil field.

For the new study, Xodus says it determined the optimal topsides configuration and operating conditions for the FPSO.
