Huisman and Jan De Nul work together on safer offshore installations

Huisman and Jan De Nul Group have jointly developed a tool that will make offshore lifting and installation more workable and safe. The new tool, the Universal Quick Connector (UQC), will be used on board Jan De Nul’s offshore installation vessels Les Alizés and Voltaire.

Jan De Nul awarded Huisman the contract for the engineering, construction and delivery of two highly innovative cranes for its vessels in 2019. They will be the largest in their class.

Improved safety and workability
The UQC is a smart, modular and robust clamp which is mounted inside the crane’s lower block. It attaches and detaches loads and tools directly to the crane’s lower block without rigging, entirely hands-free and fully automatic which results in a safer working environment. The complex task of – typically manual assisted – (de)rigging can be prepared outside of the critical path of the lifting operation. Because rigging is no longer needed, the crane can optimise available lifting heights and work subsea.

The UQC is fitted with an active rotation device which enables the accurate positioning of heavy components as well as wind turbine components with strict bolt pattern tolerances. It connects to the lifting tool with a specific pin. Any lifting tool fitted with this pin can be used. Existing lifting tools can also be used by means of an intermediate lifting eye and pin connection. In case conventional rigging is needed, a traditional hook fitted with the pin can be mounted in the UQC.
