This system is used for offshore diving applications, the maximum lowering capacity is 90 meters so it can be used for offshore platform diving operations as well. It consists of an A-frame with 2 approved man riding winches and a redundant electrical driven hydraulic power unit. All fits a 20" standard size container; even 2 off DLR-1250 will fit in one 20" container. One winch is used to lift and lower the dive bell, the other for the clump weight; a third optional winch can be used as a utility/tool winch. The function of the clump weight is to keep the dive bell straight and steady under water. In case of an emergency or breakdown of the wet bell winch the clump weight winch will be able to lift the dive bell and clump weight together.
Designed to fulfil with the requirements of Lloyds and meets UK HSE regulations for personnel lifting operations on offshore installations. The winches and A-frame are dedicated for personnel lifting suitable for diving operations and offered with Lloyds Register of Shipping (LRS) Design Appraisal Certificate and full material trace ability. They have passed the EC testing for these applications, i.e., both the winches and their technical files are in compliance with the requirements of the EC Machinery Directives.
