SPS Compact Double Hull for Petrobas


Project Type

Strengthening/Compact Double Hull


China and Brazil


2009 – 2014


Petrobras SA



SPS Compact Double Hull (CDH) was selected to provide side shell impact protection to the boat landing areas of six FPSOs operated by Petrobras SA.  This innovative use of SPS met the low-energy impact resistant requirements of IMO MARPOL Annex I Requirements for FPSOs and FSUs.  The SPS solution was approved by class society DNV, and provides protection to the adjacent cargo oil tanks.

The work was carried out at Enseada do Paraguaçu S.A. Shipyards (EEP) in Brazil and COSCO (Dalian) Shipyard, China. These projects were undertaken from 2009 to 2014 and saw a total 8,487m² [91,353 ft²] of SPS installed on six vessels.
