(In general, these are called as lifting gears). Load of the equipment is transferred to the crane through the lifting pad eyes, spreader beams, lifting wires, shackles etc. Let us discuss how the load of the module is transferred to the crane. The most basic requirement is the lifting crane supposed to be of a capacity higher than 1000 tonnes (As per norms, crane safe working load to be at least 1.25 times the weight of the equipment). Let’s consider the weight of the module is about 1000 Tonnes. Let’s assume the weight of the module is about 1000 Tonnes. We will address these challenges and will explain in detail, how to tackle these problems.įor example, a process module to be installed on FPSO. Offshore jacket platform installation in the offshore site.Offshore module lifting: Offshore vessels like FPSO, FLNGs have various process modules like chemical injection package, sulphate removal system, water injection system, etc.Figure 1: Offshore lifting Examples of offshore lifting
