Helix's Q7000 purpose-built DP3 semi-submersible vessel will undergo hull clearance among other maintenance activities at Namibia’s Port of Walvis Bay before it is all set to start for delivering a decommissioning contract off the coast of Brazil as agreed with Shell in 2022
The year-long contract also mandates plug and abandonment services at the Bijupira and Salema fields in Brazil’s Campos Basin.
It will take an estimated 10 days – that will also involve the removal of maring growth from the pontoons – to have the vessel prepared for operations offshore Brazil.
Q7000 vessel features
Helix's Q7000 vessel that was built in 2019 is equipped for riser-based subsea well intervention and decommissioning operations. With a capacity to withstand harsh environmental conditions, the unit supports production enhancement operations, well-cleanup, and field development. With a variable deck load capacity of about 3,000 metric tons besides well intervention and service fluids, Q7000 can support a crew of as many as 140 people.
The upper deck has a 600-metric-ton well intervention tower with active and passive heave compensation, and a skidding system for well intervention support equipment and tubular storage make up the large flush deck. The below deck comprises twin work-class ROV systems, bulk fluid storage, and pumping systems.
