Premuda, has returned for more SPS Overlay steel reinstatement, this time on board one of its Panamax bulk carriers, the 1984-built Four Earth. The 78,000 dwt vessel, classed by Lloyd’s Register, was repaired at Cosco Guangdong Shipyard in , formerly known as Cosco Guangzhou.
The project on board the Four Earth involved tank top reinstatement and some repairs to lower areas of bulkhead stools covering a total area of 2,876m². The shipyard’s own personnel carried out the preparatory steelwork, involving the blasting and cleaning of existing tank top plate, and the welding of perimeter bars and new top plate to create cavities.
The injection process was carried out by SPS Overlay specialists, filling the cavities with fast-setting elastomer to provide a reinstated tank top, resistant to impact damage, corrosion and possible permanent deformation resulting from excess loading. The steel reinstatement took place whilst the vessel was undergoing her fifth Special Survey.
