Wartsila announced today that they will supply a unique and patent-pending LNG fuel storage and supply system for two new trailing suction hopper dredgers (TSHDs).

The dredgers are being built by Keppel Offshore & Marine for the Dutch marine contractor Van Oord.

According to their official announcement, the Wartsila system comprises two 640m³ single-shell polyurethane insulated storage tanks, featuring a new and innovative ‘In Line Tank Connection Space (ILTCS)’ that contains the process equipment.

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 significantly benefits the vessel’s view lines for better navigational safety, while also reducing the risk of damage to equipment that is typically installed on top of a single-shell tank,” said the Finnish technology group in its release.

“Furthermore for below deck installation, the ILTCS improves fuel storage volume efficiency by avoiding the need to have the process equipment on top of the tank, which simplifies installation of the LNG system.”

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