摘要

Barge arrangement comprising a barge unit (2) provided with a load carrying facility and a tug unit (4) provided with a propulsion system (5). In order to provide for a flexible and effective LNG transportation system, the barge unit (2) is provided with a LNG-receptacle (21) and a first power generating means (3) at least partly run by means of LNG boil-off gas. The tug unit (4) is provided with a propulsion system (5) and a second power generating means (6) for providing power to the propulsion system. In a first mode of the barge arrangement (1), in which the barge unit (2) and tug unit (4) are connected to each other, the propulsion system (5) of the tug unit (4) is arranged to be powered at least partly by the first power generating means (3) of the barge unit (2). This is advantageously done by providing the barge unit (2) with a first power connection element (34) which is connectable to a second power connection element (58) on the tug unit (4). The invention also relates to a barge unit (2) and a tug unit (4).
