We provide solutions for all dynamic challenges

topside & subsea

In general

Safelink passive heave compensation solutions target dynamical challenges of all phases of the lift – topside to subsea. Our solutions improve the operational condition for a variety of applications. The goal is usually to lower the dynamic load on cranes and/or payloads, to increase stability and to reduce motion and landing velocities.

Operational challenges

Reduced lifting capacity due to wave motions
Slack wire when offloading
Re-entry at lift off

Safelink solutions

Increased lifting capacity
Damped off-loading
Quick liftoff function
Operational window without Safelink PHC

Operational challenges

Slack wire followed by snap load
Pendling motions
Slam forces caused by waves hitting the payload
Varying buoyancy and added mass

Safelink solutions

Shock absortion
Constant tension
Record actual dynamics (our more advanced units)
Control system (our more advanced units)

Operational challenges

Natural period of lifting system and wave period converges
Calculating the exact water depth for when resonance occur

Safelink solutions

Change the natural period of the lifting system beyond the maximum wave period, completely avoiding resonance
Always have full coverage against resonance at any water depth (our more advanced units)

Operational challenges

Landing speed requirement to protect payload
Insufficient active heave compensation
Limited weather window
Vessel with no active heave compensation
Ultra-deepwater installation

Safelink solutions

Significantly reduce payload heave velocity
Replacement or backup to active heave compensator
Extend the weather window
Heave compensation for short, medium and long wave periods

Operational challenges

Unexpected high pull out forces
Overload on crane or payloads lifting points

Safelink solutions

Overload protector
Constant tension
Safelink-Coil-Tubing reduce dynamics
