Abstract
System for transport of untreated drill cuttings, comprising a tank (2). The tank (2) is arranged below the deck of a ship (1) and has an output unit (10) at the bottom (6), to feed the drill cuttings towards an output opening (8). A pump (21) is provided below the bottom of the tank (2) to feed the drill cuttings through an unloading line (13). The unloading line (13) has a substantially uniform cross section and is shaped so that the velocity of the flow close to the inner wall is substantially equal in the same cross section. The tank (2) has an upper circular cylindrical part (3) and a lower frustuconical part (4) and a substantially flat bottom (6). In the flat bottom (6) is an output opening (8), which extends from the side wall (5) of the frustuconical part (4) to an inner dome or cone (11).
