A Tramp Service or tramper, on the other hand, is a ship that has no fixed routing or itinerary or schedule and is available at short notice (or fixture) to load any cargo from any port to any port, for example : A ship that arrives at Durban from Korea to discharge cargo might carry some other cargo from Durban to the Oakland in the West Coast of USA which is in an entirely different direction. From Oakland, it could carry some cargo to Bremerhaven.
