Integral tankage is forward and aft and along keelson area in the engine room.

All steel surfaces have been prepared and finished with appropriate marine coatings.

LAYOUT

The forepeak on the main deck is accessed from the foredeck only and is utilised as a ballast tank. Aft of the forepeak is the rope locker and general stowage and twin chain lockers.

The next area aft is the engine room which has the twin “Voith” units and its associated machinery. Access to this area is from the cat walk that runs above the engine room.

The engine room is on two levels with access to this area from doors fore and aft at deck level to a cat walk then stairs down to the lower deck.

The twin main engines are centrally mounted with the two power generating plants at the forward outboard end. A workshop with bench and work shop equipment is located aft to port of the main engines. The main electrical control board is situated in the control room at the forward end of the cat walk above engine room.

At the aft end of the lower deck to starboard is the crew cabin with 4 berths and adjacent to port is the drying room, these are accessed down stairs from the main accommodation deck.

The main accommodation deck has the master’s cabin forward to starboard, with the Chief engineer’s cabin and mate’s cabin opposite to port with the mess area and galley directly aft of the master’s cabin, just aft of the mess area is the engine control room.

The two main engines are English Electric 6 CSRKM turbo diesel engines which develop 920 B.H.P each at 620 rpm. These drive forward to a pair of Voith Schnedier 24E/150 six bladed units. The units are mechanically controlled.

These engines had logged approx. 16 766 hours at the time of my inspection.

The main engines are air start and are monitored from the control room.

There are two 95 B.H.P Caterpillar D330 auxiliary engines, coupled to Stamford “C” 75 KvA alternators that supply ships electrical power.

The Merryweather fire pumps are driven off a PTO on the port main engine and delivers 2000 G.P.M @1800 rpm to the 2 Merryweather dual purpose marine monitors.

The engine room also houses the Ruston-Hamworthy air start compressor and receivers, and all the ships electric pumps.

SUMMARY

Tamaki appears to have a good reputation as a capable harbour tug.

This vessel is now over 40 years old and some parts may start to become difficult to obtain.

The Tamaki had some major overhaul back in 2013 and reputedly had bottom plating replaced and her starboard Voith unit serviced at a cost of over NZD 400,000. From the reports she appears to be a reasonably sound vessel.

The vessel is lying at the Port of Auckland, New Zealand.  To receive arreange inspection please contact:
