SUBSEA SERVICES
Hydrodemolition
Hydrodemolition and ultra-high-pressure water jet cleaning solutions for offshore decommissioning, from sediment removal to reinforced concrete demolition.

What we do
Our capabilities
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.

Some challenges require more than standard equipment. We work alongside our clients to understand the problem, engineer a tailored solution and build custom-made tools that deliver results in the field.
We don’t just build custom tools—we engineer complete solutions. From the initial challenge to offshore execution, our multidisciplinary team works alongside clients to develop, manufacture and deploy bespoke equipment for the most demanding underwater operations.
