Damen Shipyards Group is to construct an ASD Tug 2312 unit for Port Marlborough New Zealand (PMNZ), which will use the newbuild to provide towage services at Picton Harbour, where approximately 3,000 vessels call annually. The tug, to be named Kaiaua, will work alongside an existing ASD Tug 2111 type, Kaiana, which Damen delivered to PMNZ in 2024.
The ASD Tug 2312 type features a length overall of 22.8m, a breadth overall of 12.03m, a depth of 4.4m and a draught of 5.6m. This model also has a bollard pull capability of 70tonnes ahead and 65tonnes astern, and can achieve a speed of 12.4knots, utilising twin Caterpillar 3512C engines (rated a combined 3,804bkW) and Kongsberg Maritime US 205S FP azimuthing thrusters.
Part of Damen’s ‘Compact Tugs’ series, the class is arranged for 360° visibility from the wheelhouse and clutter-free decks. Kaiaua will also be equipped with a single winch for both fore and aft operations, installed in the deckhouse to protect it from the elements.
Damen has outfitted the vessel with its own selective catalytic reduction (SCR) system, the Marine NOx Reduction System, which, it says, can reduce NOx emissions by up to 80%, enabling compliance with IMO Tier III requirements. Damen adds: “Although the regulations do not yet apply in New Zealand, PMNZ has committed to providing a more sustainable operation.” PMNZ CEO Rhys Welbourn comments: “This customer-led investment strengthens our ability to respond quickly, assist effectively and support shipping partners making use of the deepest berth in New Zealand. The upgrade to IMO Tier III engines also reinforces our commitment to lowering emissions and operating responsibly.”
