    Constellation starts operations of jack-up ADMarine 511 for Petrobras P&A campaign

    Constellation Oil Services has started operations of the jack-up rig ADMarine 511, under contract with Petrobras for a plug & abandonment (P&A) campaign in Sergipe, Alagoas, Ceará and Potiguar basins. Announced on March 31, 2025, the US$ 170 million contract covers the rig’s mobilization from Bahrain and a firm term of 1,143 days, with extension options. The three-leg cantilever unit, model MSC CJ46-X100D, underwent inspections and upgrades in Brazil to meet local regulatory requirements before commencing operations.

    The campaign focuses on well P&A activities linked to fixed structures in shallow waters — a segment expanding in Brazil as decommissioning programs progress. ADMarine 511, capable of operating up to 375 feet (114 meters) deep, completed classification surveys and technical modifications at Estaleiro Atlântico Sul before deployment. Constellation highlighted the project’s contribution to local employment and compliance with Brazilian safety standards.

    The contract reinforces the participation of international operators in Brazil’s P&A segment and signals Petrobras’s intention to accelerate decommissioning activities in shallow-water areas. For suppliers and local yards, the campaign opens demand opportunities for mobilization, inspection, and compliance services.

  • Hybrid AHTS tender

    Hybrid AHTS tender

    Last Friday, Petrobras received offers for the AHTS tender with hybrid propulsion (battery packs). The opportunity aims the hire of up to 2 vessels for a 4-year firm contract period with mobilization expected between July and September this year or 120 days after contract signature, whichever occurs latest. There was some concern over the battery packs requirement however, even with many requests not accepted by Petrobras during the tender process and several postponements of the submission deadline, the opportunity displayed a decent number of competitors, granted this was the first ever public tender to demand a hybrid propulsion solution. Amongst a total of 9 vessels presented to Petrobras, CBO snatched the first two places at USD 39.650,00/day with their AHTSs acquired from Finarge – AH Liguria and AH Valletta. Although bidders had to comply with the battery requirement, the winning rates did not wander too far from the USD 35.000 winning day rate in the previous AHTS tender which did not require any kind of hybrid propulsion. Despite not waiving the hybrid propulsion while understanding the technical and logistics challenges involved in such adaptation, Petrobras granted the awarded vessels a 12 month-window from the start of the contract to be fully compliant with this requirement.

    Decommissioning activity (P&A)

    Helix Energy Solutions recently announced a new deepwater well decommissioning (P&A) contract with Shell Brasil. The project is expected to start in 2024 with a 1-year firm contract period for the Bijupirá&Salema fields, located in Campos Basin. Helix will employ the riser-based well intervention vessel Q7000 for this project. The DP3 equipped vessel can perform production enhancement operations such as well clean-up and field development support as well as decommissioning activities in water depths up to 3,000 meters. Shell Brasil acquired the fields and FPSO Fluminense from Enterprise Oil in the early 2000’s becoming a pioneer on the offshore production in Brazil.
