Technology group, Wärtsilä, is to supply a unique, patent-pending LNG fuel storage and supply system for two new trailing suction hopper dredgers being built by Keppel Offshore & Marine for Dutch marine contractor, Van Oord.

The Wärtsilä system comprises two 640m3 single-shell polyurethane insulated storage tanks, featuring a new ‘In Line Tank Connection Space (ILTCS)’ that contains the process equipment.

“Our experience in the marine industry’s LNG fuel gas market is unmatched, and this latest development of the famous Wärtsilä LNGPac fuel storage, supply and control system reflects this knowledge and experience,” said Antti Kuokkanen, vice president, electronics of entertainment and processing at Wärtsilä Marine.

This LNGPac-ILTCS has the process equipment mounted in front of the tanks, instead of the usual on-top installation. For on-deck applications this is said to benefit the vessel’s view lines for better navigational safety, while also reducing the risk of damage to equipment. Furthermore, the ILTCS is said to improve fuel storage volume efficiency, thanks to its more straightforward installation.

“We are very pleased to collaborate with Wärtsilä, a globally recognised leader in LNG fuel systems, for this project,” said Jaap de Jong, director, ship management department, Van Oord. “Thanks to this unique technology we’ll be gaining more experience using LNG as an alternative fuel in our dredging fleet,” he added.

The Wärtsilä equipment is scheduled for delivery to the yard in mid-2020 for the first vessel, and in autumn 2020 for the second.
