Project Description

Shortly before the oil production at the USAN field about 100km off the cost of Nigeria started end of February 2012, the subsea network consisting of 16 umbilical cables and risers had to be connected to the floating production vessel (FPSO - Floating Production Storage and Offloading Vessel). Using 16 SLU-70, the risers and umbilical cables were lifted about 100m and maneuvered through preinstalled tubes on the FPSO. From mid October until mid December 2011 the Heavy Lifting Team conducted the lift successfully.
