Offshore decommissioning refers to the complex process of safely retiring and dismantling offshore oil and gas platforms once they have reached the end of their productive life. This crucial phase involves the removal of equipment, well plugging, and site restoration to minimize environmental impact and ensure compliance with regulatory requirements. The offshore decommissioning process plays a vital role in the energy sector as aging offshore infrastructure must be responsibly managed.

The decommissioning process begins with detailed planning and engineering assessments to evaluate the condition of the structures and to determine the best removal methods. This is followed by well abandonment, which involves safely sealing the wells to prevent leaks. Next, the topside and subsea structures are dismantled using specialized vessels and equipment. Finally, the seabed is cleared, and environmental restoration activities are conducted to return the site to its natural state or prepare it for other uses.
