Invincible: Performing P&A – safely and efficiently

During the 1½-year-long plug and abandonment campaign undertaken by Maersk Invincible at the Valhall DP platform, the rig performed consistently and efficiently, resulting in no “Total Recordable Cases” since new build, and saving our client
more than 1 billion NOK compared to original budget.

During this operation, the rig was also used as a hotel for the Valhall complex, accommodating approximately 85 hotel guests. The rig has a maximum POB of 180,
making it a flexible solution for fixed installations and clients. In addition to completing the P&A programme with zero incidents and well ahead of budget, the rig ran on
shore power, reducing the yearly NOx emissions by 186 tons and the CO2 emissions by approximately 16,000 tons.
