Abstract
Abstract An oil-collecting ship having two floating bodies which can be spread apart and which are hinged together at their rearward ends. Each of the floating bodies is a stable ship's body half. The two halves are provided with oil suction devices for picking up oil which has been pushed together by the floating bodies in a spread-apart condition. At least one locking device keeps the floating bodies in the unspread, closed state parallel to the longitudinal axis of the ship. A main drive is also provided. The bow of each ship's body half is provided with an auxiliary drive unit. Various arrangements of each body half are described.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
An oil-collecting ship comprising: an elongated ship body including two bouyant seaworthy body halves arranged to be separable from one another generally along the vertical longitudinal plane of symmetry of said ship body; a movable joint arranged at the stern of said ship body for directly connecting the rearward ends of said body halves so that said body halves can be separated to a stable spread apart condition relative to one another to collect oil on the water surface; means for skimming the oil from the water surface after the oil has been contained by said body halves when in said spread apart condition; a first locking device arranged at the forecastle end bulkhead of said ship body for holding said two body halves together in abutting relationship in a closed condition; at least one main drive arranged at the stern of said ship body for propelling the ship when said two body halves are in said closed condition; and two auxiliary drive units each arranged at the bow of a different one of said two body halves for separating said two body halves and for propelling the ship when said two body halves are in said spread apart condition.
