MARITIME PROJECTS
Lewek Constellation Pipe-Lay Star E
MAS designed Lewek Constellation for the delivery of complex projects in water depths exceeding 3,000 metres. The DP3 vessel has Ice Class notation as well as multi-lay and heavy lift-capabilities. Her multi-lay tower supports both rigid and non-rigid pipelines and her Huisman mast crane can lift up to 3,000 tonnes.
Swift Mover Lewek Constellation was built at Sofel’s yard in Vung Tau, Vietnam. She is 178.27 metres in length and 46 metres wide, with a draught of 10.5 metres. She features exceptional manoeuvrability, courtesy of a series of Rolls-Royce thrusters. She is also able to transit swiftly, reaching up to 12.5 knots. Power is delivered from two MaK 5,760kW, six MaK 2,880kW and four Hyundai 2,565kW main generators and distributed via a 6.6kV 4-split switchboard. Emergency generation is provided by a Caterpillar C32 generator of 790kW capacity. She features on board accommodation for 239 persons in single cabins. Additionally, she offers client offices, meeting rooms, recreation rooms, smoking rooms and a gymnasium. Her heli-deck, at 27.5 x 27.5 metres, is designed for a Sikorsky S-92/S-61N helicopter.
Heavy-Lift Stop Off The 178.2-metre vessel has already demonstrated her heavy-lift capabilities in a project offshore Gabon, West Africa from Vaalco Gabon. The contract saw Lewek Constellation working alongside Lewek Express on
The Lewek Constellation has been in Rotterdam these past few months for outfitting. This included the installation of an 800t Huisman Multi Lay System, two Schilling work class ROVs and a 200t MacGregor crane. Before her arrival in Rotterdam, she carried out a project for Vaalco Energy off West Africa. EMAS AMC Vice President of Assets Mr Frank van Tilborg talks to Yellow & Finch about the completion of this unique pipe and cable lay vessel. the construction of two platforms for the Etame Marin Extension Project. Mr Van Tilborg: “We had a project of opportunity when we came out of the shipyard in Vietnam. On the way to Rotterdam we passed Gabon. For that scope we needed only the 3,000t crane, which Huisman had installed in April last year. “Her work included installation of two jackets and
topsides with flare booms and boat landings. All work was completed, on time and on budget.” Speaking of the project, Vaalco Energy Construction Manager Craig Devenney says, “The EMAS AMC project team worked extremely well with the Vaalco team on a very significant part of our Etame Marin project – the installation of two new production platforms on our offshore Gabon permit. The Lewek Constellation, their impressive newbuild vessel, performed the heavy lifts of the platform, jackets and decks…”
Port Tour “After we finished the Vaalco project, the vessel sailed to Schiedam in the Port of Rotterdam in October last year. First we went to Mammoet, where we loaded on board two work class ROVs from Schilling and associated equipment. Then we moved on to Huisman and loaded the pipe-lay tower,” Mr Van Tilborg states. The tower is a Huisman Multi Lay System – a combined pipe-lay tower for both reel and flex lay through a central moon pool. The system consists of four 1,200-tonne removable rigid pipe reels and two fixed 1,250-tonne carousels for flexible pipe. It boasts two 600-tonne traction winches and storage capacity for 4,000-metre steel wire rope.
