SY Koo contacted IMG late in 2012 to carry out an extensive refit program including major works such as a full repaint, generator rebuilds, electrical and hydraulic survey. The vessel arrived early in September where a large portion of the engineering work list was undertaken including the electrical and hydraulic surveys which identified the extensive work scope to achieve during the overall refit period. A large portion of the works was carried out along side at Silo Marina before the vessel headed off on charter until February. During that time, IMG finalised plans for the reminder of the refit which included fully encapsulating the vessel under a tent alongside in the water to carry out the repaint of hull and super structure. On completion of the repaint the vessel was hauled to carry out their under water works and renew antifoul. During the repaint the generators where rebuilt and the hydraulic and electrical remedial works continued concurrently. On launch the vessel was fully operational and the remainder of the deck gear and fittings where reinstalled. The vessel finally left NZ shore for Vanuatu in early July.
