DNV Lifting Frames
We recommend to use DNVGL-ST-E273 Portable Units Class R60 for as this will be conservative for most lifting frames, subsea baskets and spreader bars. When it comes to design of lifting equipment, safety must be the number 1 priority. A risk assessment will be done to evaluate all aspects with the lifting arrangement.
The lifting frame or spreader frame will be designed according to your custom requirement for weight and loads (SWL), number of slings and the location of the padeye and lifting points on the object to be lifted. The total lift height may also be limiting and driving the design og the frame.
eSubsea also design custom and standard subsea lifting baskets for handling of equipment from vessel and down to the sea floor.
