Subsea Buoyancy Repair and Refurbishment

Not quite ready for a new set of buoyancy modules for your ROV yet? Looking for a way to revive old, damaged or worn buoyancy modules, giving them a second life?  

Our subsea buoyancy repair and refurbishment service is designed to provide you with an alternative solution as modules get worn and damaged, extending service life to ensure you get maximum usage. 

Our service

Modules undergo a full inspection including stripping back of any coatings in damaged areas to inspect the material core; a review of all metallic inserts to check for damage, breakage or corrosion; overall inspection of the modules checked against the original specifications including weight in air and weight in water calibrated testing; and a dimensional laser scan.  

We then produce an in-depth report showing the extent of necessary works and a full scope of works detailing the required actions to bring them back to operational standard.

Modules are assessed depending on the level of damage/wear and recommendations are given for the specific repairs required for the system and the associated costs and timescales. Any modules that are deemed beyond repair are identified with details of any fundamental failures documented.

Key Features

As part of our subsea buoyancy repair and refurbishment service, all works are completed using approved materials and processes and finished to industry-recognised standards. Our complete range of materials has DNV approval of manufacture, and our 11500 depth-rated material has DNV type approval. We provide all work undertaken with a 6-month warranty, giving you peace of mind.  

Along with your ‘as new’ modules, you receive a final documentation package which includes: an overall certificate of conformity, buoyancy certificates, dimensional laser scan report, and material certifications for any syntactic foam or metallic inserts used.  

Should refurbishment not be an option, we will work with you to find a cost-effective solution for a brand-new module. 

The initial inspection is a fully chargeable service based on the size and quantity of the modules being assessed. An estimate can be given for the cost of repairs using video and photographic evidence; however, an accurate quote cannot be provided until the full inspection work is complete.  

After the inspection, you can choose whether to go ahead or not. There is no obligation to proceed with the recommended repairs.
