Advanced Hydrodemolition for Offshore Decommissioning
Precision Cleaning for Offshore Compliance
In the challenging world of offshore decommissioning, the Petroleum Act 1998 mandates the removal of structures at least 3 metres below the natural seabed. This process involves not only cutting but also the meticulous clearing of platform piles, which are often filled with decades-old debris and stubborn grout layers. SUBMAR‘s cutting-edge hydrodemolition technique ensures that every pile is cleaned and prepared to meet the strictest industry standards, leaving no trace behind.

The beast has arrived
Submar introduces its latest 1,300 bar pump with 212 L/min capacity, housed in a DNV 2.7-1 offshore container. Powered by VOLVO PENTA, it’s built for hydrodemolition and decommissioning.
Cutting Through Challenges: A New Approach to Multistring Conductor Cutting
Multistring conductor cutting presents a unique challenge—how do you maintain cutting power through water layers? At SUBMAR, we’ve tackled this problem head-on, working with a leading fluid dynamics expert to develop a cutting head that keeps the jet together. With real-world tests coming up soon, we’re on the verge of an exciting breakthrough. Stay tuned!
Close co-operation, it pays off!
When our machine designs were ready, a unique collaboration with VYTECH transformed our assembly process. By working directly in their workshop, we eliminated delays, improved efficiency, and gained valuable insights from their skilled technicians. This partnership not only streamlined production but also enriched future innovations.
