Four new next-generation short-sea cargo vessels ordered by Wijnne & Barends Chartering based in the Netherlands, an affiliate of the Dutch Spliethoff Group, will feature liquefied natural gas (LNG) propulsion and storage systems provided by the technology group Wärtsilä.
The ships, which are currently being built at the WuHu Shipyard in China, will be among the first of their type to be powered by LNG fuel. Wärtsilä, in collaboration with the naval architect and the owners, developed a customised solution due to space restrictions on the short-sea cargo ships. The Wärtsilä LNGPac storage and supply system is to be installed below deck without compromising the cargo hold space.
The propulsion efficiency of the vessels will be optimised as a result of Wärtsilä’s Opti Design capabilities that tailors the propeller and HP nozzle to specifically align with the vessel’s hull. These integrated technologies will be supported via Wärtsilä’s Data Collection Unit (WDCU) with iCloud based services and remote monitoring to optimise operability, fuel economy, and periodic maintenance.
The four ships will each have a Wärtsilä 34DF dual-fuel main engine, a Wärtsilä gearbox, a Wärtsilä controlled pitch propeller (CPP) with HP nozzle, and a Wärtsilä LNGPac system. The equipment will be delivered to the yard during Q4 2020, and the first vessel is expected to be delivered during autumn 2021.
The 5800 DWT Lo-Lo (lift-on, lift-off) vessels will operate in the Baltic and North Seas and will be Finnish/Swedish Ice Class 1A classified. Six previously ordered vessels for Wijnne & Barends, which are already under construction, are also being fitted with Wärtsilä main engines and CPP propellers.
“We are very pleased to have these next-generation sustainable vessels. Minimising our environmental footprint has long been a focal point for us, and the reduction of emissions is a fundamental part of this. The new vessels running on LNG fit well into our continuous drive for greener operations,” said Ad Toonen, technical director, Wijnne & Barends.
The order with Wärtsilä was placed in December.
