Seadrill, one of the world’s largest drilling contractors, has announced it is in advanced discussions regarding a new five-year contract for the drillship West Polaris.
This new contract will start in direct continuation of the existing assignment which is scheduled to be completed in October 2012. The potential contract revenue for the five-year period is approximately US$1.16 billion. A final agreement is expected within July 2012.
The Samsung-built ultra-deepwater drillship was delivered to Seadrill in 2008.
Helix Well Ops UK (Well Ops), a business unit of international energy services company Helix Energy Solutions Group (Helix ESG), has successfully completed a three-month campaign for West Africa’s first well intervention work and subsea well operations conducted from a mono-hull intervention vessel.
Operating the 132-metre (433ft) long Well Enhancer, Well Ops performed a subsea tree change out, well suspensions, well maintenance and production enhancement on seven wells in water depths of up to 471m (1,545ft). This project represents the deepest operation conducted from Well Enhancer since it joined the fleet in 2009.
The Well Enhancer’s arrival in the waters west of Africa marked the emergence of mono-hull-based well intervention services in a region that is experiencing rapid development. Compared to rig-based methods, intervention programs delivered from mono-hull vessels provide numerous operational and cost benefits to operators.
Steve Nairn, Well Ops’ regional vice president of Europe and Africa, said: “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.”
Well Enhancer provides remotely operated vehicle (ROV), saturation diving and riser-based and riserless well intervention services. It features a 150-tonne multipurpose tower which is capable of deploying slickline, e-line and coiled tubing tool strings for well interventions in water depths of up to 600m (1,968ft) for wireline and 200m (656ft) for coiled-tubing. The vessel’s other key features include a 7⅜” subsea intervention lubricator which is a conduit for both live well access and well containment, an 18-man saturation diving spread, work and observation class ROV’s, kill pumps, and a 100-tonne crane which is rated to operate to water depths of 600m (1,968ft).
A business unit of Helix Energy Solutions Group, Aberdeen-based Helix Well Ops UK provides a range of well operation and decommissioning services using specialist vessels and innovative equipment. Launched in 1987, MSV Seawell was a pioneer of the light well intervention market and completed its first wireline intervention project in 1988. In 2009, Well Ops expanded its fleet with the launch of Well Enhancer, a 132-metre (433ft) long well intervention and diving vessel. The company employs 70 staff in Aberdeen and a further 300 offshore.

Polarcus Limited, a pure play marine geophysical company with a pioneering environmental agenda, specializing in high-end towed streamer data acquisition from Pole to Pole announces, has signed a Letter of Intent with an undisclosed client for a 3D seismic acquisition project offshore West Africa.
The project, to be acquired by POLARCUS SAMUR, will commence in late January and is expected to run for approximately 40 days.
Delivered Q1 2011 Polarcus Samur is an ultra-modern and Arctic-ready 8 streamer 3D vessel capable of towing both conventional and wide tow spreads, including Polarcus’ First Pass™ 3D technique requiring lateral streamer separations of 200m. Built to the ULSTEIN SX133 design and incorporating the innovative ULSTEIN X-BOW® hull, this vessel combines the latest developments in maritime systems with the most advanced seismic and source technol-ogy commercially available. The vessel is also amongst the most environmentally sound seismic vessels in the market with diesel-electric propulsion, high specification catalytic convertors, a double hull and advanced ballast water treatment / bilge water cleaning systems. The vessel complies with the stringent DNV CLEAN DESIGN notation.
