The Ulstein-designed platform supply vessel ‘CBO Pacifico’ left the Estaleiro Alianca yard last week. The newbuild went straight into contract for Petrobras. The vessel is the second of the PX106 design delivered to CBO this year.

“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,” says Ingar Kaldhol at Ulstein Design & Solutions.

He has worked closely with the yard’s project team throughout the building process of the first two of six Ulstein-designed X-BOW platform supply vessels to be constructed in Brazil.

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 will be working on eight year contracts for Petrobras.

It was in 2010 and 2011 that CBO decided to order the Ulstein designed PSV s for Petrobras’ oil rig support activities outside Brazil. Their demands were such: The ships had to adapt to more and more complex operations and bring with them 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. The contracts with Ulstein include the deliveries of design, engineering, main equipment and commissioning follow-up.

‘CBO Pacifico’ has a length of 76.3 metres, with 16 metres across her beam and a depth to main deck of 7.5 metres. The cargo deck area is 660 square metres. Three of the tanks are multitanks of the Cargomax system. She has diesel electric propulsion and azimuth propellers, and can keep a speed of approximately 15 knots. ‘CBO Pacifico’ complies with the CLEAN notation from Det Norske Veritas.

The four PSVs of the PX105 design will be delivered during 2012–2013.
