Hikitia

Hikitia is a working self-propelled floating steam crane in Wellington, New Zealand. She is thought to be the only working steam crane of her type in the world. She is also the sister ship to the Rapaki, formerly of the Port of Lyttelton, which is now at the New Zealand Maritime Museum.

Engines

Twin screws are driven by surface-condensing direct-drive compound engines which were supplied with steam by a coal-fired Scotch boiler with two furnaces. A similar but oil-fired boiler replaced the original boiler in 1963. In 1980 this was also removed and the present two locally made small modern package boilers were installed.[2] These new boilers produce less steam than the original ones.

Crane

The hull of the vessel was built by Fleming & Ferguson and the crane was built by Sir William Arrol & Co. of Glasgow. The crane alone weighs 310 tonnes, and was built to lift 80 tonnes. However, while dismantling the wreck of TEV Wahine it is thought that she lifted 140 tonnes.[3] In 2004 she lifted 100 tonnes to maintain her lifting licence of 80 tonnes. Her most recent lift was a 20 tonne ice plant in Lyttelton.

Refurbishment

Hikitia travelled to Lyttelton in June 2009 for hull, tail shaft and various other underwater repairs.[4] While in Lyttelton, she moved an ice plant between wharves to repay part of her refurbishment at the port's dry dock. The venture south was the ship's first time out of Wellington since 1926.
