An arrangement for evacuating people from an offshore installation having a lifeboat and an arrangement for a free-fall based lifeboat launch with a tilted ramp characterised in that the ramp of the free-fall launching arrangement is mounted on the ramp axle, has a wire rope winch and is movable. The power hydraulic mechanism of the ramp consists of an arrangement of the two lower and upper identical hydraulic cylinders, a gear bar, a gearwheel of the ramp axle and the additional gearwheel of the gear bar. Piston rods of hydraulic cylinders are arranged on two opposite sides of the gear bar and are connected to the ends of the gear bar. The gear bar engages with the additional gearwheel engaging with the gearwheel of the ramp axle.

A container for maintenance capsule as a component of a maintenance system for an offshore wind turbine maintenance program. The container transports tools, parts and maintenance personnel to and from respective wind turbine towers. The container is seaworthy, watertight and floatable, and can be loaded on a maintenance vessel which carries the container to and from a wind turbine tower.

A lifeboat hook assembly comprising a hook-shaped beak (5) and a release mechanism (6), said hook shaped beak (5) is rigidly connected to a lifeboat (2) at one end, said hook shaped beak (5) having a downwardly oriented shoulder (18) against which a loop (17) is adapted to rest so that the lifeboat is suspended in said loop (17), said release mechanism (6) is coupled to the hook-shaped beak (5) and is adapted to move relative to the hook-shaped beak (5) between a locked position (8a, 10a) wherein the loop is prevented from escaping from the shoulder (18), and a releasing position (8e, 10e) wherein the loop (17) is allowed to escape from the shoulder (18), an actuator (11) is coupled to the release mechanism (6) and is adapted to move the release mechanism (6) between the locked position (8a, 10a) and the releasing position (8e, 10e). The invention being distinctive in that said hook shaped beak (5) or said release mechanism has a first guide slot (7) and a second guide slot (9), said other of said hook shaped beak (5) or release mechanism (6) has a first guide pin (8) and a second guide pin (10), said first guide pin (7) being adapted to engage with the first guide slot (8), said second guide pin (10) being adapted to engage with the second guide slot (9).
