Increase the Workability of Your Offshore Lifting Operations

Every offshore lift has a workability ceiling - the sea state beyond which a crane operation becomes unsafe or simply has to wait. That ceiling determines your weather windows, your project schedule, and ultimately your cost per lift. Seaqualize builds motion compensation systems that push that ceiling higher, so your vessel keeps working when others are standing by.

Which technology fits your lift?

There isn't one answer - it depends on the motion you need to control and where in the lift cycle it happens.

Compensating vertical hook movement from a floating vessel? Active heave compensation keeps your load's vertical position stable even as the crane vessel rises and falls with the swell. Our Heave Chiefs deliver in-line active heave compensation for floating installation and feeder lifting operations.

Lifting between two moving vessels, or placing large structures with precision? A single-axis fix isn't enough once surge and sway start moving your load off-target. Our Full-Motion Chiefs actively corrects heave, surge and sway together: full 3D motion compensation, including damping of pendulum swing - for floating-to-floating, floating-to-fixed lifts and offshore wind installation.

Lowering equipment through the splash zone to the seabed? Motion compensation performance is where conventional passive heave compensators struggle: resonance, gas-volume tuning, and lost precision right when it matters most. Our Reef Chiefs delivers Active Heave Compensation-level motion decoupling from a passive, fail-safe system, all the way to seabed touchdown.

Not sure yet which situation applies to your operation? Our Workability Analyses team can model your specific vessel, load and sea-state conditions and tell you exactly how much additional workability you'd gain - before you commit to any system. Combined with Lifting Decision Support, you get an operator's-eye view of what's actually achievable in your weather window.

Why workability is the metric that matters

Sea state limits, not crane capacity, are usually what stops an offshore lift. Every additional 0.5m of significant wave height (Hs) your system can handle safely translates directly into fewer waiting days, more usable weather windows, and a lower cost per completed lift. That's the number our systems are engineered to move.
