Jetty
The jetty with bulkhead, which was designed to accommodate grain vessels up to 20,000 tons, is of the finger type. 725 ft. 8 in. in length and 30 ft. wide for future extension to 40 ft. It is a monolithic reinforced con- crete, cast in situ deck, 2 ft. 9 in. thick, supported by steel hexagonal box piles. with a 6 ft. 6 in. square conveyor tunnel running under the deck.
Over two hundred 16 in. piles were driven, of a maximum individual length of 160 ft. and of a total length of 26,575 ft. Some 3,200 cu. yd, of 1:1:2 concrete, 5,000 lb sq. in. at 28 days, and 300 tons of reinforcement were placed in the deck.
The fendering on the upstream side only of the jetty and around the bulk- head consists of timber rubbing pieces. steel beams and patent Andre rubber shear units. The downstream side of the jetty is to be used for berthing of small coastal vessels. The bulkhead is an isolated unit connect- ed to the jetty by patent shock ab- sorbing concertina units. Two of the piles were test loaded to 180 tons over the water.
The jetty carries a travelling pneu- matic intake plant, fitted with suction nozzles attached to flexible telescopic intake pipes carried on booms which can be swung from side to side and luffed up and down. The plant sip- hons the wheat from the ships hold at the rate of 150 tons per hour to the conveyor tunnel for transfer to the storage silos.
Power House
As all plant and equipment throughout the complex is electrical- ly operated, a power station of steel frame construction with Q-deck roof- ing, equipped with four generating sets. each having an output of 820 kw under site conditions, was con- structed 1⁄2 mile away from the mill building.
The power units consist of Ruston type 6 ATC vertical pressure charged intercooled 6-cylinder diesel engines, coupled to Lancashire Dynamo Cryp- to alternators capable of an annual output of 30 million units.

gines are cooled by means of a closed circuit fresh water system and oper- ate on heavy fuel. The raw water
cooling system is supplied with sea water, from a small pumping station and timber jetty constructed on the
May 1965. Slipform platform 90 ft, up showing central jack control shelter
