Subsea Hoisting Equipment
The term ‘subsea’ describes fully submersible equipment, operations or applications. Subsea hoisting equipment and subsea systems are often associated with industries such as oil & gas, marine science, off-shore engineering, sea bed surveying, oil-rig maintenance, ocean exploration, shipwreck recovery, sea floor mining and many more offshore lifting operations. Subsea lifting is a specialised field where all subsea equipment has to comply with stringent regulations.
Lifting Hoists Direct can supply a range of subsea lifting equipment for offshore lifting applications which can be used under-water either manually (by a diver, for example) or remotely (using a ROV). We offer a range of sub sea lifting equipment including; lever hoists and chain blocks suitable for subsea lifting operations. Our subsea systems have lifting capacities up to 20000kg, and some models are specifically designed to be used with a ROV – a remotely operated vehicle. ROV’s are usually tethered to a vessel/ship with an umbilical tether via which communications such as signals, commands and power are sent back and forth under the instruction of the operator.
This sub sea equipment enables lifting operations and intricate tasks to be safely carried out with the range of interfaces on offer. The hydraulic hot-stab connection; the rotary torque receptacles classes 3, 2 & 1, and the ‘D’ handle, ‘T’ bar or ‘Fishtail’ direct drive manual connector.
Suitable for Subsea Conditions
These subsea lifting hoists are more than your standard industrial lifting hoists. They have to be much more, due to the fact that they are going to be used in salty sea water. These briny conditions not only greatly accelerate corrosive conditions, but being immersed in water will undoubtedly wash away the special greases and lubricants that keep the hoist functioning. There is also the possibility of debris swimming into the mechanics and adversely affecting a standard hoist.
With our range of Subsea lifting equipment these issues are removed or greatly reduced. This is due to their special corrosion protection and design features which enable the hoisting devices to cope with the extreme subsea environment. All components have been fully tested and certified and pass the necessary standards needed to deem them fit for sub sea lifting use.
