Wärtsilä 34DF Dual Fuel Engine for 5,800-Cubic-Meter Craft
Wärtsilä will provide a six-cylinder 34DF dual-fuel main engine for Coralius, a 5,800-cubic-meter liquefied natural gas bunker and feeder vessel being built for Sweden’s Sirius Veder Gas AB by Royal Bodewes of The Netherlands.
Sirius Veder Gas is a joint venture owned by the LNG pioneer Anthony Veder and Gothenburg-based Sirius Rederi. Sirius Veder Gas is to operate the 99-meter (325-foot) Coralius for Skangas under a long-term charter agreement (HHP Insight, January 23, 2015).
In addition to the main 34DF engine capable of running on either LNG or diesel, Wärtsilä will supply a reduction gearbox with PTO/power takeoff, and a Wärtsilä controllable pitch propeller.
Wärtsilä claims “unequaled experience in providing dual-fuel propulsion solutions for the LNG shipping market, and the latest Wärtsilä 34DF engine version features high power output and reduced fuel consumption in both gas and diesel modes.” Operating on LNG, the vessel will comply with the IMO’s Tier III NOx emission regulations without no secondary exhaust cleaning systems.
“Since Wärtsilä introduced dual-fuel engine technology, more than 1,300 Wärtsilä DF engines have been ordered. Similarly, bunkering and feeder vessels such as this one are also increasingly taking advantage of our proven technology,” Wärtsilä Marine Solutions GM Göran Österdahl said in a release.
Vessel Delivery in 2017
“This extensive experience adds tremendous value as it allows us to provide expert engineering and project support to the yard, which importantly saves time and reduces risk,” Österdahl said.
“We are committed to developing energy-efficient solutions for small- to mid-size LNG shipping,” Anthony Veder CEO Jan Valkier says in the Wärtsilä engine announcement. “The use of LNG as a marine fuel is rapidly increasing and there is growing demand for efficient bunker and feeder vessels. Wärtsilä has both the technology and the experience necessary to meet the needs of this market,” he said.
The Wärtsilä equipment is scheduled for delivery in 2016 and the vessel is due to be delivered in February 2017.Contact information is only available to premium subscribers. Click here to purchase a premium subscription.
