Ship-to-Ship Transfer

Term from Ship Captain Roles industry explained for recruiters

Ship-to-Ship Transfer (also known as STS transfer) is a method of moving cargo between two ships positioned alongside each other, either while stationary or underway. This is like a carefully choreographed dance at sea where vessels transfer oil, liquefied gas, or other cargo without going to port. It's an essential skill for maritime officers, particularly in the oil and gas shipping industry. Think of it as mid-air refueling for ships - it requires precise navigation, careful planning, and extensive safety measures. This operation saves time and money by avoiding port calls, but requires specialized knowledge and experience to perform safely.
