ABL Energy & Marine Consultants Brasil has been appointed as Marine Warranty Surveyor (MWS) to support Subsea7 with the transportation and installation campaign for the SURF infrastructure for the Mero 3 and 4 developments offshore Brazil.

Mero 3 and Mero 4 projects envisage the subsequent build-up of subsea pipelines and associated SURF (subsea risers and flowlines) infrastructure, at both fields in Brazil’s Santos Basin, at water depths between 1,850 and 2,100 meters.

The scope will encompass pipelines installed on Mero 3 (FPSO Marechal Duque de Caxias) and on Mero 4 (FPSO Alexandre de Gusmão) Projects.

ABL’s scope of work will include the technical document review and approval of operational and engineering documentation, suitability surveys of the fleet proposed, on-site attendance to witness and approve all critical onshore and offshore operations, approval of limiting environmental criteria, and attendance at all HAZID and HAZOP meetings.

ABL’s operation in Brazil will be responsible for delivering this scope with offshore transportation and installation (T&I) work currently underway.  

'We are pleased to support Subsea7 in this important next phase development of the Santos basin. Our track record as MWS on Mero 1 and 2 demonstrates ABL’s experience in the Mero Field and our contribution to the safe and successful installation of SURF infrastructure in Brazil’s deep waters.'

Andreas Theophanatos, ABL’s Regional Director for Brazil

The operation of the unitized Mero field is conducted by the Consortium operated by Petrobras (38.6%), in partnership with Shell Brasil (19.3%), TotalEnergies (19.3%), CNPC (9.65%), CNOOC (9.65%) and Pré-Sal Petróleo S.A (PPSA) (3.5%), as contract manager and the Brazilian Government’s representative in the non-contracted area.  

ABL’s operation in Rio de Janeiro, Brazil, is one of the founding offices of the global consultancy ABL Group. Combining the market-leading MWS expertise of London Offshore Consultants in Brazil, acquired in 2020, it has supported more than 14 FPSO T&I campaigns since 2020 alone. Its track record also includes significant experience across the Buzios Field developments, Brazil’s largest oil field. ABL Brazil has additional surveyor and consultancy presence in Santarém, Itajaí and Salvador.

ABL is part of the global consultancy ABL Group ASA, which is listed on the Oslo Stock Exchange.
