Our approach integrates advanced geotechnical, structural, and hydrodynamic expertise to ensure high-quality, cost-effective solutions.

We work closely with our clients’ technical teams, fabrication, and installation personnel to optimize designs for both performance and cost efficiency. This collaboration allows us to deliver tailor-made solutions for various subsea challenges.

Our capabilities include the design and supply of specialized subsea systems such as:

• Automatic porpoise detection devices
• Wellhead protection structures (both permanent and temporary)
• Drilling and jacket mating templates
• Systems for tensioning 1000-tonne Dyneema slings
• Wave particle velocity measurement structures
• Support systems

These solutions are designed for efficient installation, often utilizing special technical MOUs on site.

Integration Testing

We provide design and field services related to the repair and modification of subsea structures and pipeline systems. This includes preparing diver procedures and conducting onshore integration testing to ensure system functionality and safety.

Subsea Repair

Antaeus Ultralift specializes in designing subsea repair solutions for offshore installations, which are typically installed with ROV and/or diver assistance on existing platforms. Our services also include designing fiberglass-lined dump and cooling water caissons with drilling connectors for replacement due to corrosion.
