Weather-Independent
and Safer Subsea Lifting
Innovation Beneath the Waves
The adventure started over 30 years ago in the early 1990s. One of Norway’s biggest oil companies at the time, requested that ROVs should be able to handle variable buoyance. The driving force behind this endeavor was our Operations Manager, Jostein H. Reinsnos. Fueled by determination, he embarked on the challenge of creating a Variable Buoyancy System (VBS).

Our systems are already performing subsea operations. Browse gallery for more in-depth footage from various operations.
Operational
Efficiency
With VBS you can perform intricate tasks without surface lift wires. Wet storage of equipment, parallel activities, and tooling transport are seamlessly achieved, all under ROV operation, eliminating the need for surface recovery. This streamlined approach showcases the autonomy and versatility of ROVs.
Operational
Capability
Our VBS systems makes it possible for ROVs to handle larger tools with ease, with neutral buoyancy for precise control and enhanced visibility. It reduces the need for thrust. This extends the weather window for tasks – invaluable for diverse underwater missions.
Technical
Benefits
Our operations exhibit a positive environmental impact while maintaining low Health, Safety, and Environment (HSE) risks. With no pressure on the deck and stable lift through the water column, we prioritize both sustainability and safety, ensuring a secure and environmentally responsible approach.
How the
VBS Works
By decreasing pressure, water is pumped out.
By letting in water the pressure will equalize
Our systems offers lifting capacity between 0.5 - 8 tons

Theory
Everything started with the question;
Is it possible to create vacuum subsea?
And how can it be used?
Create Void
By decreasing pressure, water is pumped out thus create an uplift force enabling VBS to lift heavy objects.
Reduce Lift
By letting in water the pressure
will equalize, this reduces the lift force
and the load will sink.
