The refrigerated container ship Australian Venture was the first of five largely identical refrigerated container ships commissioned by the Australian National Line, Melbourne, Associated Container Transportation, London, Overseas Container LTD., London, and New Zealand Shipping Corp., Wellington, from Bremer Vulkan were. With their high reefer container capacity of around 1275 20-foot porthole reefer containers (Reefer-TEU = R-TEU), they were considered to be the reefer container ships with the world's largest cooling capacity. The largest reefer ships of this time had around 18,000 cbm of cooling capacity in 16 to 20 cooling decks and the Australian Venture class with around 1275 reefer containers had around 42,000 cbm of cooling capacity.
history
They were laid down from October 1976 to May 1978 and delivered from February 1977 to September 1978 and testify to the intensive construction work on the Bremer Vulkan. The special thing about these ships was the high refrigerated container capacity, which was necessary due to the refrigerated cargo consisting of meat and fruit.

Ship description
The reefer container ships Australian Venture , ACT 7 , Resolution Bay , Mairangi Bay and New Zealand Pacific had an overall length of 248.6 m, width of 32.3 m and a draft of 12 m and were measured at around 44,000 GRT. Two slow-running MAN two-stroke diesel engines each had a drive power of 26,640 hp (19,580 kW) at 122 rpm and operated without a gearbox on two propellers with five blades and 6.3 m diameter. This gave the ships a nominal speed of 24 kn at 0.85 MCR. The towing tests were carried out in Wageningen, swell and maneuvering tests at the HSVA in Hamburg.
Five diesel generators from MAN, type G8V 30/45 ATL, with a nominal output of 1650 kW were installed to generate electricity . Two exhaust gas boilers , each 3.5 t / h at 8 bar nominal pressure, and two oil-fired auxiliary boilers with a nominal output of 5 t / h at 8 bar nominal pressure for district and port operations were used to generate steam.
The containers were stowed nine next to each other on deck and eight vertically one above the other below deck. The cargo cooling system was supplied by Hall Thermotank and worked with the refrigerant R 22 and brine. Four screw compressors and a piston compressor with eight cylinders were used as refrigeration machines. The porthole refrigerated containers were supplied by the ship's own cargo refrigeration system. They were accommodated in the cooled, insulated holds 3–9 and could be cooled to −23 ° C, in the hold 8 to −29 ° C. They were supplied with cold through insulated air ducts, in which the air coolers, through which the brine flowed, and the container couplings were located.
