Although the modern DFDEs have lower sulphur dioxide and finer particulate matter emissions compared to conventional diesel engines, vessels that use shore power at berth produce no localised emissions. However, a few LNG terminals, such as the Dahej LNG berth on the west coast of India, operate with an open berth without a breakwater, making mooring and berthing difficult as the vessel is constantly moving.
The igus shore power energy chain for LNG terminals provides flexible tidal compensation, even for horizontal and rotational movements. For additional safety, this system has a 3-step release mechanism: step 1 – alarm; step 2 – power shut down; and step 3 – emergency disconnection.
