Offshore Lifting Knowledge Hub
The physics and practice of heave compensation, shock absorption and subsea lifting — from wave basics and vessel response to the DNV rules and the engineering trade-offs behind specific offshore operations. Written to turn a lift problem into a specification.
From lift problem to specification
Start with the operating case: water depth, vessel motion, hook load, allowable landing speed, splash-zone exposure — and whether the load is being installed, recovered or held in tension. Those inputs decide whether passive, adaptive passive or active compensation — or a dedicated shock absorber — is the right direction.
Before comparing equipment, write the load case down the way a crane supplier or certification body will read it: static hook load, expected dynamic amplification, required stroke, target sea state, rigging length and crane type. The articles below give you the vocabulary and the governing equations; CONSTELLATION turns the case into an operating window.
Compensation & shock systems
How each architecture controls heave and absorbs shock — and where each one fits.
Offshore operations
The physics and procedure behind the lifts our equipment is built for.
Screening & planning
How a lift case becomes an operating window — and what that window is worth.
Fundamentals
Wave, vessel and load basics — the language every lift case is written in.
DNV standards
The rules that frame offshore lifting — what each standard covers and when it applies.
Have a lift case?
Send the structure, the vessel and the site — we’ll screen the case in CONSTELLATION and return the operating window, the governing limit and a practical product recommendation.
