Robert Allan Ltd. is pleased to announce that Maki and Ika Nui, two RAmparts 2100-CL harbour tugs were successfully delivered to Eastland Group. The newly delivered tugs were constructed at Cheoy Lee Shipyards and are the first Robert Allan Ltd. designed tugs to operate in Tairāwhiti (Gisborne), New Zealand.
The Maki (orca) and Ika Nui (big fish) names were announced in the summer of 2021 after suggestions from the public. Eastland Group operates in Gisborne on the North Island, the easternmost commercial port in New Zealand. Nearly 3 million tonnes of logs pass through the port each year.
Key particulars of the RAmparts 2100-CL are:
- Length, overall (excluding fenders): 21.4 m
- Beam, moulded: 11.0 m
- Depth, least moulded: 4.4 m
- Maximum draft (navigational): 4.5 m
- Gross Tonnage: 273 GT (international)
Main tank capacities at 100% are:
- Fuel oil: 41 m3
- Potable water: 5 m3
The tug was designed and constructed to the following LR notation:
✠100A1 Tug, *IWS New Zealand Coastal Service, ✠LMC, UMS Notation
Propulsion machinery consists of:
- 2 x Caterpillar 3512C main diesels 1500 kW at 1600 rpm
- 2 x Schottel SRP 360 FP Z-drives
The harbour tug is equipped with deck machinery including a bow winch from MacGregor.
Ship-handling fenders at the bow consist of an upper row of cylindrical fenders and a lower course of W-fender. Sheer fendering consists of “D” rubbers and “W” block type fendering at the stern.
The accommodations have been outfitted to a high standard for an operating crew of five. The deckhouse contains an entrance lobby, the galley, mess, two officer cabins and a public WC. There is also a provision store and laundry in the lower deck. The wheelhouse is designed with a single split control station which provides maximum all-round visibility with exceptional visibility to the bow and side fendering, as well as operation on the aft deck. The engine room features an acoustically isolated switchboard room.
Records taken during sea trial show none of the crew cabins have noise level higher than 65 dB(A). This means the extremely quiet boat will provide comfortable working and living environment for its crew.
Trial results were as follows:
- Bollard pull, ahead: 50.5 tonnes
- Free running speed, ahead: 12.4 knots
We wish fair winds and calm seas to the Maki and Ika Nui.
