Hydrex underwater installation brings fuel savings
Belgium based Hydrex has installed Propeller Boss Cap Fins (PBCF) on several tankers during their respective stops in Rotterdam, Ghent and Antwerp.
The underwater operation means that the ships will not have to wait for their next scheduled drydock visit to start benefitting from the fuel savings the PBCF’s will bring.
Drydocking would have cost up to two years of savings and by doing it this way calculations indicate that the owners could earn back the money of the underwater installation in around eight weeks.
During the operation, the alignment of these Propeller Boss Cap Fins was monitored on an underwater video camera on the workboat to ensure that installation went smoothly.
In 2012, Hydrex replaced two PBCF’s on a 110m tanker in Singapore, which was apparently the first underwater installation of a PBCF.
