USA: Helix Sells Its Three Pipelay Vessels

Helix Energy Solutions Group, Inc. has agreed to sell its three pipelay vessels, the Caesar, Express, Intrepid and related equipment in separate transactions for total cash consideration of $252,750,000.

On October 15, 2012, Helix entered into an agreement to sell the Caesar, Express and related equipment to Coastal Trade Limited for a total of $238,250,000. The sale of these assets is expected to close in two stages as each vessel completes its existing contractual backlog. The Express closing is expected to occur in February 2013 and the Caesar closing is expected to occur in July 2013. Helix has received a $50 million deposit in connection with this transaction which is only refundable in limited circumstances. The closing of this transaction is subject to customary closing conditions.

In a separate transaction, on September 26, 2012 Helix sold its pipelay vessel, Intrepid, to Stabbert Maritime Holdings, LLC for $14,500,000.

Helix will retain its Ingleside, Texas spoolbase facility and provide pipelay spooling services to the market.

Owen Kratz, President and Chief Executive Officer of Helix, stated, “As we previously discussed, our strategy is to aggressively invest and grow our Well Intervention and Robotics businesses. We see the divestiture of our pipelay fleet as an important step in accelerating our corporate strategy.”

Spain: Metalships & Docks to Build Subsea Construction Vessel for McDermott

McDermott International, Inc. (McDermott) will build another high capacity reeled pipelay vessel with top-tier payload capacity, tentatively named Lay Vessel 108 (LV108). The vessel will be a sister ship to the recently completed subsea construction vessel the Lay Vessel North Ocean 105 (LV105), and is to be built to similar specifications at Metalships and Docks S.A.U. shipyard in Vigo, Spain.

LV108 is another milestone in our vessel renewal program focusing on the subsea construction market for flexible and rigid product installation,” said Stephen M. Johnson, Chairman, President and Chief Executive Officer of McDermott. “Market analysis indicates that the subsea and deepwater construction market is expected to continue to grow and there is demand for more tonnage in both the rigid reel lay and flexible lay markets. The LV108 is expected to meet this need.”

LV108 is designed for advanced deepwater operations with a high-capacity tower for rigid and flexible pipelay and state-of-the-art marine construction equipment that will enable installation of a variety of products to a depth of 10,000 feet, including rigid-reeled pipelines, subsea components and hardware, and deepwater moorings for floating facilities as well as flexible products – cables and umbilicals.

The principal characteristics of the vessel, such as payload, tension capacity and product size, will mirror those of the LV105, but McDermott anticipates enhanced functionality of the LV108 equipment design compared to the LV105. Delivery of LV108 is anticipated to be around third quarter 2014 for outfitting of the custom-designed lay system, built by a specialist fabricator in Europe.

The vertical reel will have a nominal payload of 2,500 tons plus, subject to vessel loading conditions, and a lay tower operational between 90 and 40 degrees. The nominal tension capacity is expected to be 400 tons, and the range of pipe the vessel can install is between 4 to 16 inches diameter. This 427-foot, dynamically positioned vessel will be equipped with a 400-ton heave compensated crane, will have a transit speed of 15 knots and will operate across a range of water depths up to more than 10,000 feet.

In May we completed building and outfitting the LV105, a vessel that aims to improve our worldwide capabilities to meet the growing needs and technical challenges of the subsea and deepwater markets. The vessel will perform its first project in Asia in up to 4,430 feet of water. We look forward to LV108 joining the LV105 and other vessels in our fleet in 2014,” said Johnson.

Taken on board Helix ESG’s pipelay vessel, Express, these photos show two Pipeline End Terminal manifolds (PLETS) as they are hoisted off an adjacent supply boat and lowered down to the seabed.

A PLET is used on one, or both ends of pipelines to provide connection point from the pipeline to existing subsea structures in place.  The existing structure may be a subsea tree, another PLET or a manifold and are connected by a jumper.  The PLETs and other subsea structures have upward looking connectors while the jumpers have downward looking connectors.  This configuration allows the jumpers to be installed using Remotely Operated Vehicles (ROVs).

Helix Subsea Construction, a business unit of Helix ESG, is installing this PLET as part of the overall scope of Subsea Umbilical, Riser and Flowline (SURF) work for Noble Energy at the Noa Field, offshore Israel. The field is in approximately 2,556ft of water (779m) and is being developed for natural gas.

French oilfield services firm Technip announced Thursday it has been awarded a contract by Exxon Mobil Corporation for subsea equipment on the Hadrian South natural gas project in the Gulf of Mexico in approximately 7,500 feet (2,300 meters) of water.

The project consists of a subsea tie-back to the planned Anadarko operated spar platform, Lucius.

The contract covers:

  • Project management, procurement and installation of two 7-mile long flowlines and associated jumpers
  • Installation of a 9-mile umbilical, associated foundation and flying leads
  • Pre-commissioning.

Technip’s operating center in Houston, Texas, will execute the contract. The flowlines will be welded at Technip’s spoolbase located in Mobile, Alabama. The Deep Blue, a deepwater pipelay vessel from the Technip fleet will install the subsea equipment in 2013.

Croatia: Viktor Lenac to Convert SHCV Sampson into Crane and Pipelay Vessel

image

Viktor Lenac Shipyard has been recently awarded a contract for the conversion of the vessel SHCV “SAMPSON” (managed by Cyprus’s „VShips“ and Great Britain’s „Zafiro Marine“) by “CARVAL INVESTORS”, a leading global alternative investment manager.

The existing vessel is an offshore gas and oil field installation vessel, built in 2010. She is 180 m long and 32 m wide, carrying a crane of 1.600 ton capacity. “SAMPSON” will be converted into a crane and pipelay vessel, one more conversion on Viktor Lenac’s respectable reference list of complex projects in conversion and offshore among which Helix Producer I, Seminole, Kommandor 3000 and others, establishing its position as one of the few specialized shipyards for ship conversions and gas platform construction in the entire region of the Mediterranean.

Six new Diesel generators (2200 kW each) will be installed in two independent engine rooms. New ship systems will be installed with more than 40 tons of piping. Two new thrusters will be installed i.w.o. existing fresh water tanks. HiPAP for dynamic positioning will be relocated in newly built structural trunks. New A&R winch room will be built and outfitted i.w.o. existing hold no.1.

Complete pipe laying equipment (tensioners, track supports, conveyors, pipe loader etc.) will be installed with hydraulic systems on main deck. A new pipe lay tunnel (300 t) and A-frame structure (276 t) will be built and installed. A new stinger structure (390 t) for laying offshore pipelines will be built.

The existing ship systems will be modified to accommodate new equipment, propulsion and power generation.

Two engine rooms, two switchboard rooms and two thruster rooms will be outfitted and HVAC system will be installed in new ship spaces.

More than 150 km of cables will be installed in total.

The superstructure will undergo considerable modification including gym, sauna, swimming pool etc.
