Petrobras has launched a new tender for subsea decommissioning services involving the retrieval of flexible pipes, risers, and flowlines from three production platforms in the Campos basin. The work is part of the company's accelerated program to decommission aging assets and, in some cases, replace them with new floating production, storage and offloading vessels to extend the life of mature fields.

Tender Structure and Lots

The tender was issued on 16 December and is divided into two primary packages, with an optional third. Lot A involves the retrieval of 47 kilometers of flexible pipes and 17 flowlines extending 11 kilometers. Lot B covers the pull-out of 45 kilometers of flexible risers and 24 flowlines measuring 22 kilometers. An optional Lot C is a "virtual package" encompassing all the equipment from both lots, offered in an attempt to attract more competitive pricing from contractors.

Platforms and Scope of Work

The equipment to be retrieved is linked to three semi-submersible platforms scheduled for decommissioning: P-09 in the Corvina field, P-18 in the Marlim field, and P-25 in the Albacora field. The contract workscope includes the pull-out of various subsea systems located in water depths of up to 1400 meters, such as:

• Electrical cables and fibre optics
• Gas-lift, water injection, and chemical injection umbilicals
• Electro-hydraulic umbilicals
• Gas production and oil production pipes

Contract Terms and Conditions

Petrobras is offering a 550-day contract for Lot A and a 590-day contract for Lot B, with specific milestones to be achieved by 210 days and 330 days in each package. The bidding rules stipulate a local content requirement of at least 15%. Although all systems are in the Campos basin, services can be extended to the Santos basin at no additional cost to Petrobras if an agreement is reached with the winning contractor.
