![]() 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.Equipment exceeding the capacity of the shore crane is usually lifted using floating craneįigure 1: Offshore lifting Examples of offshore lifting Shore crane with limited lifting capacity: Generally shore crane lifting capacity is only up to 200 tonnes.Sometimes, when a vessel is berthed port side, but it’s required to lift up or install equipment in starboard side, which cannot be reached by the shore crane When shore crane cannot perform the lifting.During offshore installation, i.e., Installing any process module, structure at the operation site.In this article, we will discuss offshore lifting operations and associated engineering analysis, safety precautionary measures, contingency plans, and challenges involved in lifting. Offshore lifting is a common operation in offshore construction or installation projects at sea.
