Tankers are designed to transport specific types of cargo and therefore meet special requirements

Tankers vary in size from small, local coastal tankers to ULCC (ultra large crude carriers), which are among the largest ships in the oceans today. They are designed for the specific needs of their freight and transport route with draft usually limited by the depth of the harbor or straights along the preferred shipping route. These workhorses need to perform in the toughest conditions, delivering their valuable cargo safely without spills or accidents. Tankers frequently sail in environmentally sensitive areas subject to strict NOx, SOx, and particulate emission requirements. They need durable yet efficient engines and propulsion systems to keep them sailing strong while staying within these limits.
