Kooiman develops LNG dual-fuel push boat

Published by
LNG Industry,

Kooiman Marine Group has announced that it has developed a push boat that features an LNG dual-fuel propulsion system. The design has been fully approved by Lloyd’s Register (LR), ADN, and the Central Commission for the Navigation of the Rhine (CCNR).

The vessel features four Wärtsilä 6L20 dual-fuel engines, plus a DF auxiliary engine. The main engines feature a double-walled gas fuel system, which ensures that the engine room arrangement is free of any hazards. In addition to this, the four propulsion lines concept with shaft generators combined with batteries to store surplus power whilst sailing upstream enable a downstream trip on only two engines using the stored power for the ship’s systems.

In the statement, the company said: “It is not only the LNG installation that will reduce emissions dramatically, the four propulsion line concept with larger overall propeller diameter, tunnel shaped hull and a complete novel design of retractable flanking wings will add another 16% to total ship’s efficiency, that also will reduce emissions on both sides of the chain (fuel production and consumption).”
