Safelink Shock Absorbers and Passive Heave Compensation Solutions

We increase safety and extend operational windows

Efforts to reduce costs and increase productivity are underway across the entire spectrum of the offshore industry. Compensating all heave motion directly at the crane hook enables the offshore industry to significantly reduce costs, gain efficiency, increase lifting and subsea lowering capability, increase productivity through minimizing downtime, and reduce carbon footprint.

Safelink is your complete supplier of passive heave- and dynamic load compensation solutions. Our range of products target dynamic challenges throughout the entire lift – from topside to subsea installation. We remove dynamics and specialize in delivering state of the art shock absorbers and passive heave compensation solutions.

“Our PHC solutions applies to all marine lifting operations – from oil & gas, salvage, offshore wind and wave industries”

Applications for PHC

Whether your challenges require a standard unit or a complex solution – our range will cover it. We like to say that our limit within passive heave compensation is only a subject to one’s imagination. Our team of highly skilled engineers enjoy new challenges, and take pride in delivering nothing but excellent performance.

Compensating motions at the crane hook

Topside benefits

  • Unique ability to compensate the movement where the actual loads are applied
  • Instant respons
  • Absorbing peak loads before they get transferred to the crane construction
  • Protecting the crane and payload
  • Increasing the offshore lifting capacity

Subsea benefits

  • Avoid resonance
  • Overload protection in case AHC shuts down unexpectedly
  • Reduce landing velocity; as primary heave compensation, in combination with AHC or backup for AHC
  • Avoid re-entry after landing
  • Overload protection during subsea retrieval

Specialized Engineering

Our team is committed to continuously improve our mathematical models and simulators to achieve excellent performance.

Plenty of Features

Our passive heave compensation solutions have an increasing amount of optional features to meet all dynamic challenges for a variety of applications.

Research, testing and verification

We carefully design every detail of all components in our products according to advanced mathematical models and simulators. Our team is not settled before our estimations are close to 100% accurate.

Therefore we have equipped our state of the art PHC units  with a monitoring system to verify and evaluate the performance. This way we continue to reach for our goal of 100%

World Wide Support

Safelink offer technical support to clients all over the world from our offices in Norway and Finland, or through one of our partners in Australia, Brazil, Canada, China, India and the US.

We know exactly how it works

The graph shows actual recorded values during an offshore installation. The information has great value for the verification of our own technology.

Hook Velocity

Stroke Velocity

Payload Velocity

Excellent efficiency throughout the entire lift. Max recorded DAF through the splash zone of 1,02. Max landing speed at about 0.05 m/s – reducing the hook velocity (landing velocity without Safelink Kraken) significantly.
