Ship history

CBO Atlântico is the first platform supply vessel (PSV) of the PX106 design from ULSTEIN and was named in a formal ceremony in Rio de Janeiro on 24 November 2011, and delivered in February 2012. The vessel is the first of two for shipowner CBO (Companhia Brasileira de Offshore) and was constructed at the Estaleiro Alianca shipyard. CBO Atlântico entered into an eight-year contract with the Brazilian state oil company Petrobras immediately after delivery.

The two contracts with CBO included the delivery of design, engineering, main equipment and commissioning follow-up from ULSTEIN. These were the first two, of totally six, ULSTEIN-designed X-BOW platform supply vessels to be constructed in Brazil. Before, CBO already had two PSVs of P106 design from ULSTEIN in their fleet, delivered in 2006 and 2007.

(From press release 14 May 2012): “The finish and quality of these vessels are impeccable. We are very pleased with the good cooperation we have had throughout these projects with shipowner CBO and the Estaleiro Alianca yard,” said a representative of Ulstein Design & Solutions AS upon the occasion of the delivery of vessel number two.

These first two PX106 vessels are relatively small vessels that comply with Petrobras’ PSV 3000 tender. The next four are of the larger PX105 design that complies with the PSV 4500 tender. All vessels were purposed to work on 8-year contracts for Petrobras.

It was in 2010 and 2011 that CBO decided to order the ULSTEIN-designed PSVs for Petrobras’ oil rig support activities outside Brazil. Their demands were such: The ships had to adapt to more complex operations and bring new technologies to provide quality services, ensure safety and protect sensitive marine environments. The PX106 and PX105 vessels are designed for efficient and flexible transportation of bulk and general cargo to installations offshore.

CBO Atlântico has diesel-electric propulsion and azimuth propellers. She complies with the CLEAN notation from Det Norske Veritas. Three of the tanks are multi tanks of the Cargomax system.

2022: CBO has contracted Ulstein Power & Control for deliveries of Ulstein Shore Power Systems for CBO Atlântico and CBO Pacifico, including an interface to ULSTEIN IAS. Shore power reduces the running hours on generators, and reduces fuel consumption and emissions at port all the way down to zero - An important step in the direction of zero-emission vessels.
