SYNOPSIS

Recent study by IHS Markit found the annual expenditure of global offshore decommissioning works will rise from $2.4 billion in 2015 to $13 billion by 2040. Therefore, it is important to ensure our engineers are ready for these increase workloads. For example, they must understand the processes involved during a decommissioning work.

One of the critical processes in an offshore decommissioning work is the lifting and lowering activities. This is where the existing topsides is lifted from its jacket and lowered down onto the seabed. The main risk is the weight of the structure, in which when combined with the environmental dynamic response (such as wind and wave), could exceed the capacity of the lifting system.

In addition, when the lifted structure is crossing the splash zone, the structure faces a transition from being fully lifted in air towards being fully submerged. This will result to the structure being subjected to environmental loads such as slamming wave and current forces. At the same time, the rigging equipment may be subjected to unexpected increase in hook load due to loss of structure’s buoyancy by the oscillating sea surface.

This talk will discuss the above and also the analysis methodology of the lifting process through the splash zone.
