Major modifications have been completed on the first floating production storage and offloading (FPSO) conversion in Mexico. The ECO III, classed by ABS, originally was built as a chemical carrier before being purchased by MARECSA (Maritima De Ecologia, S.A. de C.V) for conversion to a FPSO at the DEMERSESA Shipyard in Tuxpan, Mexico. The FPSO’s crew quarters, helideck and on-deck piping were installed in the Mexican shipyard before it went to the US for drydocking and installation of other modules and the dynamic positioning system. The FPSO then returned to the Tuxpan shipyard for the final phase of the modifications.
