ETAP is located 240km east of Aberdeen in the Central North Sea. It is an integrated development of nine oil and gas reservoirs.

ETAP is developed using a central processing facility (CPF) operated by BP, comprising a processing, drilling and riser (PdR) platform, bridge-linked to a quarters and utilities (QU) platform over Marnock, and a normally unmanned installation (NUI) on Mungo.

The remaining seven fields all produce through subsea manifolds tied back to the CPF.

On site operations are planned to commence between mid-April and mid-July 2015, with a firm period of 13 months. In addition, Prosafe has granted BP three additional one-month options and one fourteen-day option.

Total value of the firm period is approximately $98.2m.

Trevor Garlick, Region President, for BP’s North Sea business said, "This is a significant investment in the provision of a facility that will enable us to extend the life of this valuable North Sea asset.

"The additional accommodation space will allow BP and its partners to increase activity aimed at enhancing production efficiency, improving plant reliability and maximising the recovery of oil and gas from our reservoirs," Garlick added.
