Ulstein to Build Its Largest Offshore Construction Vessel Ever

Edison Chouest Offshore and Island Offshore are ordering two new OCV vessels through the company Island Ventures II LLC. One vessel will be built at Ulstein Verft, Norway, one in USA.

Ulstein Verft has been contracted to build a new offshore construction vessel of the ULSTEIN SX165 design. This will be the largest vessel built at the yard so far, as well as its largest single shipbuilding contract. The vessel is scheduled for delivery Q3 2015.
“We are very pleased to develop the next generation of offshore vessels together with Edison Chouest Offshore and Island Offshore. They are companies with solid and extensive experience. We have worked very well together on other innovative projects, and look forward to delivering a high-quality product that will serve the ship owners well for years to come,” says CEO Gunvor Ulstein, Ulstein Group.
“This is a demanding and challenging construction project, which suits us in every respect. We have a solid organisation that will carry out all the engineering work. Our group can offer world-class yard facilities and designs which attract attention from both crews and ship owners. We are ready, and looking forward to the assignment,” says Kristian Sætre, managing director, Ulstein Verft.

First ULSTEIN design in USA

Island Ventures II LLC has also ordered design and engineering packages for the construction of an ULSTEIN SX165 design vessel at Edison Chouest’s own yard in the United States. In addition, this agreement includes options. This will be the first ULSTEIN designed vessel to be constructed in the U.S.
“We look forward to adding these vessels to our fleet. The cooperation between our companies is excellent and we look forward to working with ULSTEIN on the construction of these multifunctional vessels,” says CEO Gary Chouest, Edison Chouest Offshore.
Island Offshore’s current fleet includes four vessels from ULSTEIN. In addition, a construction vessel for Island Ventures II LLC is currently under construction at Ulstein Verft for delivery in June 2014.

Facts about the vessels
The newly developed SX165 design has many qualities. The vessel is 28 metres wide and 145.7 metres long and can accommodate 200 people. She is equipped with two cranes that can lift 400 tons and 140 tons, respectively. She has a large moon pool measuring 11.2 by 12 metres plus two smaller moon pools with ROVs installed in a centrally located hangar. The vessel has a total of three separate engine rooms to provide extreme operational reliability: if a major error occurs and one of the engine rooms goes out of service, the ship will still have two-thirds of her operational capacity.
Health, safety and the environment have been fully considered in the development of this design. For example, the vessel will be delivered in accordance with the international regulation MLC2006 that sets out the comfort and safety requirements for the crew. The ship has four lifeboats, two on each side. In addition, the vessel is equipped with SCR catalyst system for NOx emission reduction.

MacGregor Provides Subsea Crane for ‘Island Intervention’

MacGregor, part of Cargotec, has won a contract to deliver a 250-tonne SWL active heave-compensated (AHC) subsea crane for the 120m construction vessel, Island Intervention. The crane was ordered by Marine Procurement Ltd, part of the US company Edison Chouest Offshore.

An existing vessel operated by the US/Norwegian partnership between Edison Chouest Offshore and Island Offshore requires greater lifting capability; a MacGregor 250-tonne SWL AHC subsea crane fulfils the upgrade requirements. Island Intervention is currently operating in the North Sea for the US/Norwegian partnership between Edison Chouest Offshore and Island Offshore. The vessel works in the offshore construction market and was delivered by Norwegian yard Ulstein Verft in 2011; its current lifting capacity is 140 tonnes.

“The vessel simply needs a bigger crane for the jobs that it undertakes,” says Frode Grøvan, Director, Sales and Marketing for Advanced Load Handling. “The order confirms the trend that we see of subsea modules getting larger and heavier, therefore requiring operators to equip their vessels with ever more capable cranes.”

“At MacGregor, we have the expertise necessary to ensure that retrofit projects like this run smoothly and successfully, with downtime kept to a minimum.”

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”.
