DOF Subsea USA has entered into a long-term charter agreement with Harvey Gulf International Marine for the new build DP II Multipurpose Construction Vessel, the Harvey Deep-Sea. The four year charter agreement will commence upon delivery of the vessel from Easter Shipyard, Florida in June 2013.
The vessel is the only new build Jones Act compliant construction vessel available to the market until the latter part of 2015.
Since 2010, DOF Subsea North America has experienced strong growth in capability and market recognition, delivering to the DOF Subsea Group important and challenging projects using the existing Atlantic fleet. This charter is an integral part of DOF Subsea’s planned expansion strategy as a global service provider for the deep-water offshore Survey, IMR and Construction market.
Aberdeen-based Helix Well Ops UK (Well Ops), a business unit of international offshore energy company Helix Energy Solutions Group (Helix ESG), is expanding its Europe and Africa well intervention fleet with an investment that will create 60 jobs.
A leading global provider of subsea well intervention, Well Ops will take control of the mono-hull well intervention vessel Skandi Constructor in spring 2013, after agreeing a three-year charter with DOF Subsea.
The move to strengthen Well Ops’ regional fleet, which currently includes the 132-metre (433ft) long Well Enhancer and the 114-metre (374ft) long MSV Seawell, will lead to the creation of approximately 50 jobs offshore and a further 10 onshore over the next nine months. At the moment the firm employs 70 staff in Aberdeen and a further 300 offshore.
Launched in 2009, Skandi Constructor is a 120-metre (393ft) long Ulstein SX121 DP3 mono-hull well intervention vessel that features the new X-bow design. The 8,500-tonne vessel accommodates up to 100 personnel and is capable of working in depths of up to 3,000 metres (9,842ft). It has a deck capacity of 1,470 square metres (15,822 sq ft) and features an 8m x 8m (27ft x 27ft) moon-pool, a 150-tonne crane, a multi-purpose tower with 140-tonne lift capability and two work class ROVs.
Well Ops will build and test, ready for use, a specially designed version of its 7⅜” subsea intervention lubricator (SIL) to enable subsea well interventions to be undertaken from Skandi Constructor. The SIL is a single trip well intervention system that provides well access, while managing containment when the well is ‘live’ and under pressure. The SIL is configured to undertake work through all types of subsea xmas trees. The vessel and SIL will allow Well Ops to provide its regional clients with a solution for deeper water wells and well interventions, which to date has been limited within the mono-hull vessel market.
Steve Nairn, Well Ops’ regional vice president of Europe and Africa, said: “Well Ops is extremely proud to announce the addition of a third vessel to our fleet and it underlines our commitment to providing well intervention services. Skandi Constructor strengthens our offering internationally and expands our well intervention service capability.”
The need for a third vessel in Well Ops’ fleet has been driven by demand from operators in the North Sea and in other oil and gas producing provinces. The firm recently secured contracts from a number of the North Sea’s major operators to provide light well intervention and associated subsea services from its existing vessels between 2013 and 2015.
Internationally, it has also received strong interest from operators, particularly in West Africa. This follows Well Enhancer’s deployment to the region earlier this year, where it completed what was believed to have been the region’s first well intervention project from a mono-hull vessel.
Mr Nairn added: “This is an exciting time for the company and the demand that we are witnessing is illustrative of the level of service and expertise that we can offer clients. As operators continually seek to make their operations more time and cost efficient, it is encouraging that more are turning to mono-hull vessels to conduct well intervention work.
“Our experience of providing an alternative to rig-based intervention systems has been built up over 25 years. MSV Seawell helped to pioneer light well intervention in the North Sea and we have built on this over recent years with Well Enhancer, which was the first mono-hull vessel capable of delivering coiled tubing intervention.”
