Huisman, a Dutch specialist in lifting, drilling and subsea solutions, has secured a new contract from Helix Energy Solutions Group, Inc. for the delivery of a Well Intervention System onboard Helix’s new build Semi submersible “Q7000”.
The system, which is based on Huisman’s proven Multi Purpose Tower (MPT) design, will be built by the Huisman production facility in China.
The fully integrated 800mt Well Intervention System will be capable of handling the Intervention stack, the high pressure riser and other components. The Huisman Multi Purpose Tower has the same functionality as a normal derrick but offers improved accessibility to the well center, which allows for new improved handling procedures that increase efficiency and safety. The superior accessibility to the well center and the small footprint of the MPT are ideally suited for well intervention and subsea installation services. Subsea equipment can be skidded into the well center from three sides, offering enhanced flexibility.
The active heave compensation hoist system of the MPT provides excellent means for safe landing of equipment at the seabed while the passive heave compensation system provides a safe and redundant means to supply top tension to the risers. A guide trolley, travelling the entire length of the tower, guides the subsea modules during lifting operations. The system also features multiple transfer hatches that can be used to move equipment into the well center, and a skiddable work floor covering the moonpool flush with main deck.
The skiddable work floor allows large subsea modules to be deployed, without the need for a raised work floor. When large objects need to pass the moonpool the work floor can be skidded aside. In closed position, the work floor is flush with the main deck, which significantly reduces HSE risks and improves equipment handling on deck.
In addition to the Well Intervention System Huisman will also supply a 150mt Knuckle Boom Crane and a 160mt Pedestal Mounted Crane. Previous orders from Helix, amongst others, the Multi Purpose Tower onboard the “Q4000”, “Well Enhancer” as well as the cranes for the “Q4000” and “Q5000”.

Rowan Companies plc announced today that one of its subsidiaries has entered into a three-year contract with Cobalt International Energy, L.P. for the Rowan Reliance, one of Rowan’s new ultra-deepwater drillships currently under construction at the Hyundai Heavy Industries Co. Ltd. (“HHI”) shipyard in Ulsan, South Korea. The drillship is expected to operate in the U.S. Gulf of Mexico.
The Rowan Reliance is expected to be delivered from HHI at the end of October 2014. The contract is expected to commence late January 2015 following mobilization. The effective day rate for the work will be $602,000, including mobilization revenues, and adds $660 million in revenue backlog.
Matt Ralls, Rowan’s Chief Executive Officer, stated, “We are very pleased to enter into this relationship with Cobalt. They have a very exciting growth story with a strong track record in ultra-deepwater exploration. We will complement their growth potential through our expansion into the ultra-deepwater drilling segment with the most advanced drillships in the industry. We are proud to have this opportunity to be part of the future success of this exciting company.”
The Rowan Reliance is one of four ultra-deepwater drillships being constructed for Rowan by HHI. All four drillships are based on a GustoMSC P10,000 hull design, capable of drilling wells to depths of 40,000 feet in water depths up to 12,000 feet. The DP-3 compliant, dynamically positioned drillship will be equipped with retractable thrusters, two readily deployable seven-ram BOP systems, five mud pumps, dual mud systems and a maximum hookload capacity of 1,250 tons.
With the award of this contract for the Rowan Reliance, three of the Company’s four ultra-deepwater drillships under construction at HHI are now under contract. The fourth remaining uncontracted drillship, the Rowan Relentless, is scheduled to be delivered from the shipyard at the end of March 2015.

Edison Chouest Offshore said today it will build more than 40 new vessels to meet growing demand for offshore oil and gas support in the Gulf of Mexico, the Arctic and Brazil.
The new vessels continue an aggressive build campaign the Galliano-based company launched in 2011. The privately held company, which has vessels under construction at shipyards through the U.S. and in Brazil and Poland, did not disclose the cost of the newest round of builds.
Most of the construction work will be spread among Chouest’s four U.S.-affiliate shipyards — North American Shipbuilding in Larose, LaShip in Houma, Gulf Ship in Gulfport, Miss., and Tampa Ship in Tampa, Fla. — as well as its Brazilian shipyard, Navship.
The largest portion of the new build program will be the construction of 17 diesel-electric platform supply vessels. Chouest intends to market the new vessels, which feature a new hull form designed to carry more weight while lowering hydrodynamic resistance, as a more fuel-efficient option to oil and gas operators in the Gulf of Mexico.
Chouest’s plans also include two new ice class vessels designed for service work in the Arctic and four new subsea construction vessels slated for service in the Gulf of Mexico. The company’s fleet of icebreaking vessels, which will total six when the new builds are delivered, has supported Royal Dutch Shell’s drilling activity in Alaska.
Chouest also provided an update about its affiliated port facilities at Port Fourchon. The C-Port 3 facility currently under construction will open in March and feature six covered slips to transfer cargo and provide support for deepwater support vessels. Design has begun on an additional section, C-Port 4, which could have as many as nine covered slips.
The company is also planning to expand its C-Terminal worksite at Fourchon to include outside storage areas, warehouses, cement and barite plants, and fuel, water, mud and drilling fluid sales stations. Chouest purchased the facility earlier this year.
Chouest, founded as Edison Chouest Boat Rental in 1960, operates a fleet of nearly 250 offshore service and support vessels worldwide.
In the following video, National Oilwell Varco (NOV) and ULSTEIN present what they describe as the “next generation of modern offshore vessels.”
According to the caption of the video published on Ulstein’s YouTube channel “this is the standard for future offshore construction.”
The vessel platform used is the ULSTEIN designed Deepwater Enabler.
The 160.0 m long Deepwater enabler is a Multi-purpose Offshore construction vessel of a highly flexible design that can, according to Ulstein, be customized to meet client’s specifications and requirements.
The construction vessel is designed for various offshore operations. With a simplistic customization process it can be used to install and maintain offshore wind turbines, as well as for flex-lay, well intervention and slim hole drilling operations for the offshore oil and gas industry.
If February this year, Toisa placed an order for a construction vessel of the Deepwater Enabler design. The vessel will be built by South Korea’s Hyundai Heavy Industries.
