Subsea Landing
Enhance Subsea Landings with Cranemaster®. As subsea structures become larger and more complex, controlling landing speed is crucial. Cranemaster® units effectively reduce motion during subsea lifting operations by absorbing boom tip movements, ensuring smooth and precise landings.
Operational challenges
Subsea landing operations are increasingly demanding as structures grow larger and more complex. Precise control of landing speed is critical to avoid damage to equipment and subsea installations. Factors such as vessel movement, hydrodynamic forces, and limited visibility further complicate operations, increasing the risk of impact or misalignment during placement. Advanced solutions are required to mitigate these challenges and ensure safe and accurate landings.
Cranemaster Benefits
By using a Cranemaster unit during the subsea landing, the operation will benefit from:
Reduction of landing speed.
Possibility to maintain tension in wire during landing phase.
Reduction of peak loads in case of re-lifting.
Prevention of rapid heeling of vessel during landing of heavy loads.
Subsea Landing With and Without Cranemaster
Two 700T Cranemaster units are used in parallel. Actual observed forces and movements corresponded well to the Orcaflex simulation.
Without Cranemaster:
Maximum landing speed = -0,7 m/s
Maximum crane tension = 2000 ton
With Cranemaster:
Maximum landing speed = -0,1 m/s
Maximum crane tension = 840 ton
No slack observed in the rigging
Cranemaster® Passive Heave Compensators
Cranemaster® Passive Heave Compensators enhance offshore lifting by reducing dynamic forces, protecting equipment, and improving safety. These self-contained units expand weather windows and ensure precise load positioning, with capacities up to 1600 tons and stroke lengths up to 5 meters.
