Abstract
A vessel to recover material in the form of oil and timber from the surface or bottom of the sea comprises a conveyor, which projects down below the water level and is mounted to the vessel in an elevatable manner in order to enable variation of the level of the lower portion of the conveyor in dependence upon the level on which the material to be recovered is present. The conveyor is pivotably mounted to the vessel about an axis extending generally horizontally and transversely to the longitudinal direction of the vessel.
Claims19
A vessel for recovering material such as oil from the water, comprising a first conveyor, which is pivotably mounted on the vessel about an axis extending generally horizontally and transversely relative to the longitudinal direction of the vessel, a portion of said first conveyor being adapted to be located below the water level so as to enable the first conveyor to transfer the oil out of the water, and a lifting device connected to the first conveyor to pivot the first conveyor about said axis, the improvement comprising said lifting device being designed to adjust the lower portion of the first conveyor into different levels below the water level to locate the lower portion of the first conveyor in the vicinity of the bottom of the sea to pick up material such as timber therefrom, wherein the first conveyor is rotatably mounted to the vessel about a second axis extending generally in the longitudinal direction of the vessel, and further wherein the first conveyor is rotatable about the second axis by means of at least one operating member, the actuation of which is automatically controlled by a device sensing side heelings of the vessel and which is adapted, upon side heelings of the vessel, to rotate the first conveyor about the second axis to entirely or partially eliminate the influence of said side heelings on the position of the first conveyor and the direction of the first axis.
A vessel for recovering material such as oil from the water, comprising a first conveyor, which is pivotably mounted on the vessel about an axis extending generally horizontally and transversely relative to the longitudinal direction of the vessel, a portion of said first conveyor being adapted to be located below the water level so as to enable the first conveyor to transfer the oil out of the water, and a lifting device connected to the first conveyor to pivot the first conveyor about said axis, the improvement comprising said lifting device being designed to adjust the lower portion of the first conveyor into different levels below the water level to locate the lower portion of the first conveyor in the vicinity of the bottom of the sea to pick up material such as timber therefrom, wherein the first conveyor is rotatably mounted to the vessel about a second axis extending generally in the longitudinal direction of the vessel, and further wherein the first conveyor is displacably movable in a direction towards the stern along the second axis against the action of a buffer.
A vessel for recovering material such as oil from the water, comprising a first conveyor, which is pivotably mounted on the vessel about an axis extending generally horizontally and transversely relative to the longitudinal direction of the vessel, a portion of said first conveyor being adapted to be located below the water level so as to enable the first conveyor to transfer the oil out of the water, and a lifting device connected to the first conveyor to pivot the first conveyor about said axis, the improvement comprising said lifting device being designed to adjust the lower portion of the first conveyor into different levels below the water level to locate the lower portion of the first conveyor in the vicinity of the bottom of the sea to pick up material such as timber therefrom, wherein the first conveyor at its lower end comprises an assembly to feed material on the bottom of the sea onto the first conveyor, and wherein the feed assembly is provided with at least two feed members, which are pivotably provided at the longitudinal sides of the first conveyor and movable between a first extended position and a second position, in which the members are retracted towards the lower end of the first conveyor, said feed members being adapted to be alternately pivoted to and fro between said positions and each of the feed members being connected to means to at least partially raise the feed member when it is to be pivoted from the retracted to the extended position.
