Subsea Lifting

Subsea Lifting Systems Built for Precision

Subsea lifting between a vessel and the seabed requires specialised equipment with proven performance.

Safely handling sensitive and valuable modules in rough weather demands precise control, robust structures, and integrated systems that can compensate for vessel motion and dynamic sea conditions.

Active heave compensation, accurate wire guidance, and damping systems overcome the challenges of splash zone interaction and subsea positioning.

AXTech has delivered subsea lifting systems for more than 20  years, — including the Special Handling System for Equinor’s Åsgard field, handling modules up to 420 tonnes safely in sea states up to Hs 4.5.

What we deliver

We engineer and supply winches, compensators, guide systems, and towers — tailored to operational requirements and customer specifications.

Our equipment portfolio includes:

·       IMR module handling towers

·       Pallets and power packunits (PPUs)

·       Bumper frame systems

·       Smart Tower solutions

·       Downforce tools

·       RLWI LARS systems

Each system is engineered for safe, precise, and reliable subsea handling — tailored to operation, vessel, and depth profile.

Multidisciplinary Engineering for Subsea Operations

We combine hydrodynamic analysis, multidisciplinary engineering expertise, and decades of project experience. Our track record with leading operators spans the full lifecycle — from concept to installation and service.

We continuously optimise designs and methods, ensuring each solution uses the technology best suited for the operation, or developing new approaches where needed.

Our active heave compensation systems have proven performance across multiple projects. Long-standing client relationships reflect our reliability, innovation, and operational insight.
