ZPMC has reached a major construction milestone in its deepwater jack-up crane vessel program. The vessel is being built for offshore operations in challenging marine environments and is equipped with 142 m legs and a 1,600 t revolving jib crane.

According to the provided source, the unit will be able to work in water depths of up to 90 m and deliver a lifting height of 210 m above deck. It is intended for a range of offshore duties, including emergency response, salvage work and platform maintenance under demanding sea conditions.

A key part of the vessel’s structural system is the spud can, which serves as a primary load-bearing component. The spud can measure 9.5 m in height, 17 m in length, and 16 m in width. About 60% of its structure is made from specialized steel plates.

The source said this design is intended to provide stable support during deep-sea operations while also improving resistance to wind and wave forces
