Abstract: A system for supplying electric power from an AC power source to ships, each of the ships moored at a respective berth of a quay, the system including a rectifier, having an AC and DC side, for converting AC electric power from the AC power source to DC power, the AC side arranged to be connected to the AC power source, and a plurality of ship connection arrangements for supplying electric power to a respective ship, each of the ship connection arrangements placed at one of the berths and including an inverter configurable to output AC power at a first or a second frequency and a ship connector for connecting the ship. A DC distribution network connected to the DC side of the rectifier and the rectifier is placed at a distance from the quay and each of the inverters is connected to the DC distribution network is also contemplated.

Abstract: A system for supplying electric power from a main power grid to a plurality of ships moored at a respective berth of a quay. The system includes a connection point for connecting to the grid supplying electrical power at a first frequency, a frequency converter arrangement for converting electric power from the grid at the first frequency to electric power at a second frequency, a first connector, arranged to provide power from the grid at the first frequency, a second connector, arranged to provide power at the second frequency from the frequency converter arrangement, a plurality of switches, each switch being configured to supply of power from either of the two connector to a respective berth, the system further includes a plurality of ship connection arrangements connected to a respective switch, each ship connection arrangement being adapted for connection to an electric system of a ship. A corresponding arrangement and method are also presented.

Abstract: Lock for safety belts, comprising a lock housing enclosing a lock mechanism having a release member for manual operation, and a member of lock tongues which can be inserted into the lock housing for co-operation with the lock mechanism. The lock mechanism comprises a number of lock plates one for each lock tongue, which are mounted in the lock housing for rotation about a common axis and each form an abutment for the associated lock tongue and a hook for retaining locking engagement with the lock tongue and are spring-biased to be engaged with the lock tongue against the spring bias when the lock tongue is inserted into the lock housing to be engaged with the abutment, an arresting element which can be actuated manually to be engaged with each lock plate to arrest temporarily the lock plate in the engaged position, and a latch member which is spring-biased to engage the lock plates when all lock plates are arrested in the engaged position, to retain permanently the lock plates in said position.

Abstract: Lock for safety belts, comprising a lock housing and a lock tongue which can be inserted into the lock housing. The lock tongue is displaceably mounted on a support element and is spring-biased to a withdrawn position, the lock tongue being normally displaceable to a projected position against the spring bias, a latch member engaging the lock tongue in the withdrawn position thereof to prevent displacement of the lock tongue to the projected position. A fitting for a strap can be passed onto the lock tongue in the withdrawn position thereof, said fitting engaging the latch member to release the lock tongue for displacement to the projected position against the spring bias.
