The invention discloses a multi-bar linkage mechanism based conveyor, comprising a gantry system, a multi-bar linkage mechanism based conveyor boom, a boom support, a two-drum winch, a roller unit and an automatic control system. The gantry system, the two-drum winch and the boom support are mounted on a deck of a hull. The conveyor boom is formed of multi-bar linkage mechanisms, the movement of which can be changed. Rollers are mounted on the conveyor boom. The rear segment of the conveyor boom is articulated with the boom support. The two-drum winch is connected to the multi-bar linkage mechanism based conveyor boom via a steel wire rope and by a set of gantry pulleys. A hydraulic device and a control device are arranged between adjacent multi-bar linkage mechanisms. A tension sensor is arranged at an end of the steel wire rope. The whole conveyor is controlled by the automatic control system.

A recovery apparatus and a recovery method is disclosed for recovering a watercraft, in particular for recovering a boat on board a mother ship. A frame actuator pulls a frame of the recovery apparatus relative to a carrying structure from a recovering position into a parked position. A chain drive moves a chain relative to the frame along a closed curve. The chain comprises at least one driver. A watercraft to be recovered is connected temporarily to the chain and is pulled out of the water by the movement of the frame relative to the carrying structure and by the movement of the chain having the drivers relative to the frame.

The invention relates to a boat (1) for servicing shallow canals, lakes, and rivers configured for extracting, cutting, grinding, and casting plant waste, solid waste, or agricultural plantation harvest and sending what is harvested to shore, and comprising an extractor belt (3) configured for extracting the plant waste which is deposited on a horizontal conveyor belt (9) to a grinding mill (4); and further comprising at least one drive turbine (5) and a directional stack (6).

A lift and method for lifting equipment modules, and for providing for sideways loading equipment modules, or cargo containers, onto a mounting surface of a sea vessel, such as a ship or submarine. The lift comprises a frame for supporting the equipment modules or cargo containers, and includes a number of conveying beams for conveying the equipment module or cargo container in a sideways direction in relation to the frame, and means for lifting said conveying beams in a vertical direction. The method includes, providing a lift according to the invention; arranging an equipment module or cargo container onto the lift; maneuvering the lift on a ground surface into a position substantial parallel with the hull of said sea vessel; raising the equipment module or cargo container by the lift in a vertical direction to a specific vertical position in relation to a mission bay in said hull; conveying the equipment module or cargo container sideways into the mission bay, by said conveying beams; connecting the equipment module or cargo container to a number of anchoring points within the mission bay and retracting the conveying beams out of the mission bay.

A submersible node and a method and system for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system to provide propulsion for the node between respective landed locations by varying the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.

A lifting apparatus comprises: a base part, a lifting rope, a sheave assembly, a first rotatably mounted sheave, around which the rope passes and from which the rope extends downwardly to a load, a second rotatably mounted sheave and a drive for moving the sheave assembly. The sheave assembly is mounted for pivotal movement relative to the base part about an axis of pivoting spaced from the axis of rotation of the first sheave and coincident with the axis of rotation of the second sheave. During movement of the load relative to the base part, the first sheave is moved by the drive to compensate for that relative movement, the movement of the first sheave being such that the vertical component of the movement of the first sheave relative to the load is less than the vertical component of the movement of the base part relative to the load.
