Abstract: The built-in system for testing the sprinkler system of a lifeboat is characterized in that it has a water tank (17) connected to a pipeline for the water from the water installation of the marine facility (14) which pipeline is equipped with a sprinkler system pump (2). The pipeline for the water from the water installation of the marine facility (14) has a valve for the water from the water installation of the marine facility (15) and is connected to an outboard water inlet pipe of the sprinkler system (4), which pipe has an outboard water valve (5). At a connection point (16), the pipeline for the water from the water installation of the marine facility (14) is connected to the outboard water inlet pipe of the sprinkler system (4).

Abstract: 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.

Abstract: A method for locking the rope winch which is characterized by the fact that the locking bolt is inserted when the rope drum of the rope winch is stopped, first, through one of two holes in the first lug, then through one of the arched cuttings on the wheel of the rope drum of the rope winch, and finally through one of two holes in the second lug, Then the locking bolt is secured in position with a nut.

Abstract: The present application provides a launching arrangement for a lifeboat from an offshore installation. The launching arrangement may include a garage for the lifeboat, a gate of the garage that can be opened by gravity, wherein the lifeboat can be launched either as a free fall lifeboat or by a fall of a lifeboat winch in case of an emergency situation and while a power supply is off, and wherein the garage is equipped with the gate with a wire rope winch, a lower hydraulic cylinder, and an upper hydraulic cylinder; and the gate of the garage opens by gravity by simultaneous operation of a wire rope winch of the gate and the lower hydraulic cylinder and the upper hydraulic cylinder, both hydraulic cylinders working as a closed hydraulic system; and the lower hydraulic cylinder and the upper hydraulic cylinder including piston rods.
