We had the five year old Damen tug, Waimata, up on the hard last week for her first docking in New Zealand. Heron Ship Repairs carried out the five year services on her Rolls Royce drive units and the cathodic system. We undertook several small general engineering tasks, and the haul out work was completed with a full topsides coat in blue, and a complete underwater antifoul paint system applied below the waterline. The spruced up Waimata was slipped back into the tide ready to go back to her chores.
Recent Ship Repair Projects
Heron Ship Repair set 210ft barge, AMS Gladstone, up for a piling contract in December 2018 and completed in January. Containers for an office and a lunch room were installed, and crane sea-fastening for a 400T crane was fabricated and also installed. Pile gates were fixed to the side of the barge and an on-board power system was established.
The 70ft wide AMS Gladstone will be utilised as a crane barge during construction of the America’s Cup facilities for 2021.
The 23.95m multi-cat, Iona M, was brought out of the water recently for her intermediate survey. Ship Repair overhauled and serviced the generator, as well as overhauling the anchor and deck winches. The vessel was sandblasted, and hull and topsides were painted in the new owners’ colours.
While we had the Western Ranger up on the hard in mid-2018, we carried out a complete refurbishment of the purse winch, including the rebuilding and upgrade of the main winch drum, and upgrading the shaft. We rebuilt the bearing housing as well as fully sandblasting and recoating it. When the upgraded winch was sea-trialled, it netted 130 tonnes of fish between the ship and her new 8m skiff which we also constructed. The Western Ranger’s upgraded purse winch can be confidently operated for many more thousand tonnes of catch.
