Maiden monohull intervention

OE Staff
Saturday, April 28, 2012

A three-month campaign for West Africa’s first well intervention work and subsea well operations conducted from a monohull intervention vessel was completed recently by Helix Well Ops UK’s 132m-long Well Enhancer. The vessel performed a subsea tree changeout, well suspensions, well maintenance and production enhancement on seven wells in water depths of up to 471m (1545ft), the deepest operation conducted from Well Enhancer since it joined the Helix fleet in 2009.

Steve Nairn, Well Ops’ regional VP for Europe & Africa, commented: ‘Providing operators with alternatives to rig-based well intervention brings new cost and time efficiencies to West African oil and gas projects. Because Well Enhancer deploys more quickly than a rig, and is designed specifically for well intervention work, she reduces down time and helps operators return as quickly as possible to their business of oil and gas production.’
