Aker BP will assign the two rigs to perform multiple operations, with different rate structures applying that will take into account market developments, various operating modes, and incentive schemes.
In addition, the two parties have further committed to an investment involving hybrid, low-emission upgrades to Maersk Invincible, similar to those executed previously on the Maersk Intrepid and Maersk Integrator.
These have entailed installation of hybrid power with NOx conversion units, with energy efficiency software used to monitor and reduce energy consumption and CO2 emissions.
During the first month of operations with the equivalent full set of upgrades installed, the Maersk Intrepid’s fuel consumption and CO2 emissions fell by around 25% compared to the rig’s baseline average. In addition, its NOx emissions dropped by around 95%.
The Maersk Integrator, a CJ70 XLE design delivered in 2015, is currently warm-stacked in Åmøyfjorden outside Stavanger, Norway, after recently completing a drilling campaign for Aker BP.
The Maersk Invincible, of the same design, was delivered in 2016, and currently operates for Aker BP offshore Norway.
