LNG hoists for liquefied gas trains and terminals

The LNG hoists from STAHL CraneSystems are designed specifically for maintenance work on liquefied natural gas (LNG) tanks. Due to their high-quality components, robust construction, corrosion-resistant finishes and many other features, they are ideally suited for use in coastal regions with demanding climatic conditions. The pumps, which pump the cold liquefied natural gas (–164 °C to –161 °C) in a pipe system, must be lifted out of the approximately 70 metre high tanks into the open for maintenance work up to five times a year. In view of the extreme conditions in the tank, special ropes, which are fastened permanently to the liquefied natural gas pump and therefore spend their lives in the tank, are needed for this. When maintenance work needs to be carried out, these ropes are fastened to the rope drum and hoist with quick fasteners.

The experts in our engineering department develop these special hoists according to individual requirements, specifications, quality standards and national regulations. The projects are implemented economically, effectively and in constant high quality. This includes compliance with all global regulations and standards, implementation of all international certifications and customer-specific documentation.

The LNG hoists from STAHL CraneSystems are offered in four safety levels. The LNG wire rope hoists from STAHL CraneSystems in level 3B are currently regarded as the safest explosion-proof hoists available on the market.

    Safety Level 1

    As a basic principle, LNG hoists are custom built to the individual specifications and requirements provided by systems builders and EPC contractors. Safety Level 1, the lowest level, employs explosion-protected hoists from STAHL CraneSystems’ SH wire rope hoist programme or AS wire rope hoist programme, specifically designed for routine maintenance work on LNG trains. There is only one motor, hoist gear and brake. The modular principle enables various customer requirements to be met.

    Safety Level 2

    In Safety Level 2, two rope drums from the SH wire rope hoist programme, permanently connected by a chain, are driven by one motor.
    As an option, a fast action lock can be used to exchange the standard wire rope and the rope of the liquefied gas pump. The LNG pump’s ropes can be taken up on one drum or on both drums in parallel as required. There is only one motor, hoist gear and brake. The modular principle enables various customer requirements to be met.

    Safety Level 3A

    The LNG hoist in Safety Level 3A is equipped with two separately driven motor-gear units running parallel, two rope drums and two brakes. The brakes are designed so that each one individually is able to brake or hold the load in an emergency. The brakes are synchronously controlled and act as service and holding brakes. The off-standard wire ropes permanently connected to the pump are attached to the rope drum of the LNG hoist by an optional fast action lock. Generally, lifting is performed by one load-bearing rope, the second rope runs parallel as a dead rope without load. In the unlikely event that one of the ropes should break, the second hoist can take over the load and continue lifting.

    Safety Level 3B

    LNG wire rope hoists in Safety Level 3B are masterpieces of STAHL CraneSystems’ engineering and are regarded as the safest, mosttechnically mature hoists in the world. As with the LNG hoists in Safety Level 3A, their construction is fully redundant. Increased safety is guaranteed by the additional floating and spring-loaded suspension. Only one rope acts as lifting rope when lifting the pump. The second hoist runs in parallel with a dead rope as backup. If the load rope should break during lifting, the second hoist takes over. However in Safety Level 3B, the hoist’s floating and spring-loaded suspension absorbs the impact of the abrupt load change without jolting and ensures that the load’s centre of gravity stays centred under the hoist. Lifting can continue without disruption and without damaging the valuable pump or any part of the system.
