Sembcorp Marine’s subsidiary Jurong Shipyard has secured a US$346 million contract to build a second semi-submersible well intervention rig for Helix Energy Solutions Group, Inc. (Helix), a market leader in subsea well intervention services.
Scheduled for delivery in mid-2016, the semi-submersible light well intervention rig will be built based on a design jointly developed by Sembcorp Marine Technology Pte Ltd (SMTP), a fully-owned Research & Development subsidiary of Sembcorp Marine, and Helix. Featuring the latest technology, the rig – named Q7000 by Helix – is an efficient purpose-designed platform with capabilities to perform a wide variety of tasks, including conventional and extended top hole drilling, subsea construction, decommissioning well intervention, coiled tubing operations and twin ROV deployment.
The Dynamic Positioning (DP) class 3 unit has the ability to operate in deepwater operations worldwide, including the North Sea and West of Africa.
William Gu, General Manager of Offshore Division said: “We are honoured that Helix has chosen to build their second semi-submersible well intervention rig with us. This repeat order is significant as it testifies as to their trust and confidence in our design and building capabilities in rigs with well intervention and subsea capabilities that are customised to meet this new growth segment of the market. We are committed to build on our partnership with Helix and to meet their stringent standards of quality, safety and reliability.”
Owen Kratz, Helix’s President and Chief Executive Officer, said: “We are pleased to work with our trusted partner Jurong Shipyard on this second unit of the semisubmersible well intervention rig, to be named Q7000.”
The above is not expected to have any material impact on the consolidated net tangible assets per share and earnings per share of Sembcorp Marine for the year ending December 31, 2013.
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.
InterMoor successfully replaced (8) spiral-strand platform wires on a permanent production facility in May 2011 without requiring a platform shutdown or loss of production. The operation was completed using a single Construction Anchor-Handling Vessel (CAHV) at a significant cost savings from the traditional method involving a derrick barge.
Each mooring line consisted of unjacketed spiral-strand wire at the fairlead, two sections of jacketed spiral strand in the water column and studless chain at the seafloor. Syntactic-foam submersible buoys had been installed at each spiral-strand wire connection, so each mooring line had two buoys.
Only the platform wires were to be replaced, and the remaining mooring components including the buoys were to be reused. Protecting the existing components from damage during recovery and reinstallation posed several unique challenges. One of the main operational challenges was to design a way to bring the upper buoy and platform wire out of the water and secure them on deck so that the old platform wire could be disconnected. To accomplish this, InterMoor designed and installed a custom hang-off porch at the CAHV’s stern. The porch used a combination of pneumatic and hydraulic cylinders to manipulate and align the entire porch as each buoy connection was recovered and deployed. The porch also had separate stoppers for the socket connections and a removable cradle for the buoy. Another operational challenge was the unknown condition of the buoys themselves, particularly since they were to be reused on the replacement wires. There was no industry experience at the time in retrieving foam buoys that had remained submerged at depth for over a decade. This paper will explore these challenges and others in more detail as well as the steps that were taken to successfully overcome them.
STX OSV Holdings Limited (“STX OSV”), one of the major global designers and shipbuilders of offshore and specialized vessels, has received an order for the design and construction of a large, advanced Offshore Subsea Construction Vessel (OSCV) for Ocean Installer and Solstad Offshore.
The contract value amounts to approximately NOK 1.4 billion. Ocean Installer and Solstad will have joint ownership of the vessel, which is to be operated by Ocean Installer. The vessel is scheduled for delivery from STX OSV in Norway in 2Q 2014. The hull will be delivered from STX OSV in Romania. The contract is subject to board approval by the Norwegian Guarantee Institute for Export Credits (GIEK), expected to be received on or around 20 June 2012.
The vessel, of type OSCV 06L, has been designed by STX OSV and Solstad in close cooperation with Ocean Installer, and is highly advanced in terms of station keeping, efficiency and operational performance. The vessel is designed to operate efficiently under demanding conditions and is well fitted for SURF (Subsea,Umbilicals, Risers, Flowlines) operations.
The vessel is 156.7 meters long, 27 meters wide and has an aft cargo deck area of 2,100 m2. She will be equipped with a 150 t Vertical Lay System (VLS) and a 3,000 t below deck carousel, Remotely Operated Vehicles (ROVs) in hangars launched through moonpools, and two AHC offshore cranes (400 t and 100 t) which both can operate down to depths of 3,000 meters. The accommodation facilities will have a capacity of 140 persons. The vessel is designed according to the latest environmental standards with focus on low fuel consumption.
Steinar Riise, CEO of Ocean Installer said: “We are very satisfied with placing the contract for this new-build, and are looking forward to developing our operations with this vessel, which is built for heavy construction work, and is highly advanced when it comes to station keeping, efficiency and operational performance. This investment is in line with our growth strategy, as the vessel is capable of conducting the full range of subsea construction operations in the global market. Moreover, this joint venture consolidates the strategic cooperation between Solstad and Ocean Installer”
