Huisman to Deliver Well Intervention System for Helix’s Q7000

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”.

Seadrill Orders Harsh Environment Rig in South Korea

https://i2.wp.com/d3n6f555sx1wcx.cloudfront.net/wp-content/uploads/2012/05/Seadrill-Orders-Harsh-Environment-Rig-in-South-Korea.jpg

Seadrill, one of the world’s largest drilling contractors, has ordered a new harsh environment semi-submersible drilling rig from Hyundai Samho Shipyard in South Korea. The company explained the move by the current strong demand for high specification drilling units and Seadrill’s wish to benefit from such market conditions.

The new rig will be a sister rig of the harsh environment semi-submersible unit Seadrill’s subsidiary North Atlantic Drilling currently have under construction at Jurong Shipyard in Singapore.

It will be of a Moss CS60 design, N class compliant and will be able to meet the harsh and demanding weather conditions in the North Atlantic areas. In addition, the new rig will have premium ultra deepwater capabilities including water depth of up to 10,000 feet. The rig is scheduled for delivery in the fourth quarter 2014.

Total estimated project costs is less than US$650 million including a turn key yard contract with a back-end loaded payment structure. In addition, Seadrill has agreed a fixed price option for one further unit from the yard. Seadrill has already received charter interest in the firm unit. With the strong demand Seadrill feels it is likely that the option will be exercised. However, a final decision will not be taken before August 2012.

Seadrill’s construction program now totals 18 units, including 6 drillships, 2 harsh environment semi-submersibles, 5 tender rigs and 5 jack ups. In addition to the rigs under construction, Seadrill also controls several fixed price options at various yards.

Alf C Thorkildsen, Chief Executive Officer in Seadrill Management AS says in a comment: “Based on the enquiries we receive from the major oil and gas companies and the current high oil prices, we are comfortable that the aggregate demand for modern floaters will exceed the supply of available units for several years to come. We are pleased that the good relationships Seadrill and the Fredriksen group have with the top quality yards have allowed us to get access to attractive delivery slots at competitive terms. With an expected strong cash flow from our solid contract backlog we are well positioned to secure attractive financing for our new building program. As a result we remain positive to the prospects of continuing to show higher growth and deliver better operational and financial performance than our peers in an industry that looks very attractive for the years to come.”
