Want to Cut Emissions? SLOW DOWN
Merchant ships traditionally operate in the open sea at or near full speed. This is hard on the engine, hard on the ship and hard on the crew. Slowing down reduces wear on the engine, improves fuel efficiency, reduces harmful air emissions and improves safety by providing the bridge personnel additional time to evaluate developing situations. Some marine engines, though, are designed to operate at near full load. Thus, for these engines, slow steaming creates its own set of problems – not insurmountable…
