摘要： Accommodation ladder having a first flight of steps of adjustable length with one end adapted for connection to a ship while its opposite end is pivotably mounted about a horizontal axis at a given level above the quayside. This flight of steps is also mounted for pivotal movement about a vertical axis passing between its opposite ends at a location substantially spaced from its horizontal pivotal axis. A second flight of steps is adapted for mounting at one end adjacent the quayside to pivot about the vertical axis and extends upwardly from this mounting to interconnect with the first flight of steps enabling joint pivoting with the latter about this axis.

摘要： An escape arrangement for use on board a rig (10), platform or similar sea-based construction includes in combination a gangway construction (15, 16) and an inflatable slide (23). The gangway construction (15, 16) is in normal use adapted to form a self-supporting gangway connection between two sea-based constructions (for example between a working rig and an accommodation rig). Further it is adapted to be axially displaced and to be readjusted about a vertical and/or a horizontal axis from the one construction relative to the other construction. The slide (23) is adapted to be able to be stowed away in an inactive condition in a manner requiring little space and in an active use condition to be able to be stretched out to a relatively large length and in an easily adjustable manner relative to a moveable base, to form a regulatable component in the escape arrangement. The slide (23) is fastened to the outer end of the gangway construction and is adapted for easy readjustment from an inactive to an active position to form a free downwardly hanging, direct extension of the outer end of the gangway construction.

摘要： A fire-extinguishing system for helicopter decks (10) comprises nozzles (24, 25) for the supply of foam or water to the helicopter deck and to a helicopter and the like placed on the helicopter deck. At the outer edge of the helicopter deck, just by a submerged gangway (13), and preferably also across the helicopter deck in or by an associated drainage duct (29), there is permanently arranged a conduit system (21, 22, 23) for foam or water, equipped with a first and a second set of nozzles. A first set of nozzles is adapted to direct a jet of foam or water of relatively low strength and relatively small range towards its respective established region of the helicopter deck in order to squirt or spray the same with foam or water. A second set of nozzles is adapted to direct a jet of foam or water of relatively high strength and relatively long range substantially in a direction towards the center of the helicopter deck.
摘要翻译： 用于直升机甲板（10）的灭火系统包括用于向直升机甲板供应泡沫或水的喷嘴（24,25）和安装在直升机甲板上的直升机等。 在直升机甲板的外缘，恰好通过一个淹没的舷梯（13），并且优选地也穿过相关排水管道（29）内的直升机甲板，或者通过相关的排水管道（29），永久地布置有一个管道系统（21,22,23） 用于泡沫或水，配备有第一组和第二组喷嘴。 第一组喷嘴适于将相对低强度和相对较小范围的泡沫或水的射流引向其直升机甲板的相应建立区域，以便用泡沫或水喷射或喷射。 第二组喷嘴适于引导基本上沿着朝向直升机甲板中心的方向的相对高强度和相对较长范围的泡沫或水的射流。
