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.
