Six Engines & Fuel Storage for 538-Foot ‘Spartacus’ CSD
As Well as for the New 689-Foot ‘Orion’ Construction Ship
As Gas Operating Fleet Concept Scheme for Asia Gets AiP
Finland’s Wärtsilä is talking up its role in providing half a dozen LNG-diesel dual fuel engines, onboard LNG storage, and propellers and thrusters for both a large CSD/cutter suction dredger being built in Europe and an even larger construction vessel being built in Asia.
Spartacus, under construction at the Royal IHC yard in the Netherlands on behalf of Belgium-based Dredging International (DEME) “will be the world’s most powerful CSD and the first ever to be fueled by liquefied natural gas,” Wärtsilä says.
The 538-foot (164-meter) Spartacus will have a total installed power of 44,180 kilowatts – nearly 60,000 horsepower. Wärtsilä is supplying four 9-cylinder 46DF and two 8-cylinder 20DF dual-fuel engines, as well as an LNGPac fuel gas storage and supply system with a newly designed bi-lobe tank arrangement.
Both Vessels Are for DEME/Dredging International
Wärtsilä is supplying a similar package of four 9-cylinder 46DF and two 8-cylinder 20DF dual-fuel engines, and LNGPac fuel storage and supply and propulsion equipment for the 689-foot (210-meter) Orion, as well as commissioning, site supervision and “extended project management services.”
The Wärtsilä equipment is scheduled for delivery to the Cosco shipyard in China in the latter part of 2017. Orion is also for DEME.
Orion is expected to be delivered in 2018 “and will undertake operations involving the installation of offshore windfarms in locations around the world,” Wärtsilä says. Orion “will be the first vessel of its kind to be fueled by liquefied natural gas.”
‘Fully Integrated Propulsion Arrangement’
“Wärtsilä has worked in close cooperation with the owners starting from the early stages of this large project, Wärtsilä special vessel business development GM Arthur Boogaard said in a release. “This has enabled a well engineered and fully integrated propulsion arrangement,” he said, with “an LNG fuel system that is optimized for the needs of the vessel.”
“Wärtsilä has provided excellent support throughout the design phase, and we are confident that this results in a highly efficient CSD with lower operating costs than would have been otherwise possible,” DEME head of newbuilding and conversions Jan Gabriel says in Wärtsilä’s Spartacus announcement.
“We are very aware of our environmental responsibilities, and for this reason we have opted for Wärtsilä dual-fuel engines running on clean burning LNG fuel,” he said.
“The decision to utilize clean burning LNG fuel represents our commitment to provide environmentally sustainable solutions for our operations,” Gabriel days in Wärtsilä’s Orion announcement.
Delivery in Mid-2019
“The comprehensive package of engines and propulsion machinery” for the brawny Spartcus CSD was contracted for late last year for approximately 20 million euros, or about $21.4 million U.S. at current rates, Wärtsilä says. Contracts for Orion were signed late last year and during the first quarter of 2017.
Spartacus is expected to be delivered to the customer in mid-2019 for service “in different locations around the world.” CSDs are able to dredge nearly all kinds of soils, including sand, clay and rock.” Wärtsilä notes that CSDs are used “wherever the ground is too hard for conventional dredgers to operate.”
‘Meets Current and Anticipated Environmental Requirements’
Separately, Wärtsilä is talking up a “flexible and modular natural gas operating fleet” concept with Approval in Principle from Lloyd’s Register.
“The aim of the concept is to offer global operators a more efficient and economical fleet design that meets current and anticipated environmental requirements according to the classification rules,” Wärtsilä says. The concept fleet includes an LNG storage barge, an LNG regasification barge, and a floating natural gas liquefaction barge, with a pusher tug to move them.
Advantages include “operative flexibility” and lower fleet capital and operating costs: “the pusher tug,” Wartsila says, “makes all the units mobile and transportable.”
“This is a new and innovative fleet concept that is designed to create better efficiencies for companies involved in any part of the natural gas supply chain,” Wärtsilä business development director for Southeast Asia marine solutions said in a release.
In addition to the Lloyd’s AiP, “the project has attained the authority of China’s National Patent Office,” Wärtsilä says.
