The ship owner is Belgian operator Dredging International (DEME). This will be the first vessel of its kind to be fueled by LNG and in addition to the dual-fuel engines, Wärtsilä will also provide its LNGPac fuel storage and supply system and propulsion systems. The orders with Wärtsilä were booked in the fourth quarter of 2016 and in February 2017.

"The decision to utilize clean burning LNG fuel represents our commitment to provide environmentally sustainable solutions for our operations. Wärtsilä has extensive experience and vast technological know-how in this field, which is why we have selected them as our partner in this project," said Jan Gabriel, Head of newbuilding and conversion department at DEME.

This 210-m long vessel, the Orion, will be powered by four 9-cylinder Wärtsilä 46DF dual-fuel electric propulsion engines, and two 6-cylinder Wärtsilä 20DF dual-fuel engines. Wärtsilä will also supply two custom made retractable thrusters, four underwater demountable thrusters, the Wärtsilä LNGPac storage and supply system, as well as commissioning, site supervision and extended project management services. The Wärtsilä equipment is scheduled for delivery to the yard in the latter part of 2017.

The Orion is expected to be delivered to the owners in 2018 and will undertake operations involving the installation of offshore windfarms in locations around the world.

The global LNG industry is becoming increasingly interconnected as grassroots export projects get off the ground. Another technology route for processing gas into fuels—GTL—is attracting renewed attention due to improving economics. Small-scale solutions for both LNG and GTL are at the forefront of new technological developments, while major projects using more conventional technologies continue to start up around the world.

During this webcast, we will focus on LNG, GTL, gas processing technology developments and deployments, operations, small-scale solutions, transportation, trading, distribution, safety, regulatory affairs, business analysis and more.
