Real Journeys Queenstown operations manager Luke Taylor (left) and TSS Earnslaw engineer Ken McAuliffe show some of the several tonnes of metal cut out of the 102-year-old vessel so far as part of a preventive maintenance project that began last month at its Kelvin Heights slipway.
Mr Taylor said the nine-week survey involved replacing steel plates on the vessel's hull with new marine steel.
The work was being done by a team of about 10 Real Journeys employees and specialists from Gough Bros, in Invercargill.
The vessel was expected to be ''back in business'' by about July 12.
