Fewer lost days waiting on weather.
Norwegian Dynamics builds DNV-certified heave compensators and crane shock absorbers that extend the operating window and de-risk offshore lifts — across subsea, oil & gas, and offshore wind.
Product family
A complete toolkit for motion compensation and load control.
Six product solutions cover passive and active heave compensation, crane shock absorption and tensioning. Start with SWL, stroke, installation type and operation sequence; the simplest suitable product is usually the right starting point.
Adaptive passive heave compensation for demanding subsea lifts and changing buoyancy.
View product
Compact passive heave compensation for predictable splash-zone crossings and standard subsea lifts.
View product
High-capacity passive heave compensation for heavy subsea lifts above the standard RIGEL range.
View product
Topside motion compensation and subsea active heave compensation where active feedback is required.
View product
Lightweight crane shock absorber for peak-load protection with fast setup.
View product
Backup riser tensioning for drilling and workover compensation duties.

Design basis
Wider weather windows, lower crane loads, faster turnaround.
Norwegian Dynamics equipment is selected from the lift data: sea state, wave period, payload, water depth, buoyancy and operation sequence. The result is a practical product choice to reduce dynamic loads and keep offshore work moving.
Designed around DNV ST-0378, DNV marine-operation practice and ISO 9001 manufacturing control.
Full lifecycle
From the first drawing to the last decommission.
We support the equipment we build for the entire life of the asset, in-house, with the same engineers who designed it.
Why Norwegian Dynamics
Built and supported by engineers.
We design, manufacture, commission and support heave compensation and shock absorption equipment under one roof. That keeps the feedback loop short: the same team reviews the lift data, equipment, controls and offshore realities.
