Resonance Avoidance
Prevent resonance in deep-water operations. In deep-water lifting, resonance can occur when the wave period aligns with the system frequency of the load and wire, leading to uncontrolled dynamic forces. Incorporating a Cranemaster® unit into the rigging increases the system's resonance period, effectively avoiding these destructive movements.
Operational challenges
Deep-water lifting operations are susceptible to resonance, which occurs when wave periods match the natural frequency of the load and wire system. This can cause severe, uncontrollable dynamic forces that jeopardize equipment, safety, and operational efficiency. Mitigating these forces requires precise adjustments to the system's dynamic response to prevent resonance and ensure stable, controlled lifting in challenging offshore environments.
Cranemaster Benefits
Avoid uncontrolled dynamic forces and escalating movements of load during deep water operations.
System resonance period will be increased with Cranemaster included in the rigging.
(This Orcaflex simulation shows how resonance for deep water lowering can be avoided by use of Cranemaster.)
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.
