SOLUTION FOR THREE NEW GAS FUELLED TUGS.
Three large new escort tugs contracted by Norwegian operator AstensjA Rederi will feature WArtsilA dual-fuel (DF) engines integrated with a customized gas storage and supply system also supplied by WArtsilA.
The tugs will operate primarily on LNG (Liquefied Natural Gas) but the WArtsilA DF engines provide the flexibility to select the most suitable fuel according to availability price and local environmental restrictions. The contract for the WArtsilA solution was signed in December 2014. The design of the tugs has been carried out by the designer Robert Allan Ltd in Canada in close cooperation with AstensjA Rederi.
The overall LNG system which incorporates WArtsilA's unique LNGPac fuel system a fully integrated gas handling system and the WArtsilA Gas Valve Unit (GVU) has been specially designed by WArtsilA to accommodate the need for a compact solution. The tugs will be powered by 6-cylinder WArtsilA 34DF dual-fuel engines. The WArtsilA equipment will be delivered during the first half of 2016.
