Cook Strait Ferry Terminal, Picton
Engineering Work (eg road, bridge, sawmill, dam)
An integral part of the national railway system, the Picton terminal handles 3 million tonnes of freight and 750,000 passengers annually and has been in operation since 1962.
There were severe site constraints, with the need to maintain the existing service without interruption during the construction of No 2 berth and erection of the overpass over highway and rail yards; the conversion of No 1 berth including lengthening the longarm and replacing the linkspan and gangways; and the subsequent conversion of No 2 berth for larger vessels. Dominant factors were urgency, economy, the limitations of the port itself and the desirability of high standards of public amenity.
Technical features included:
- The design of berth structures including fendering.
- The pile foundations designed for low-cost construction over water and economic variation of depth.
- The stream diversion culvert under road and railway yards which remained in service.
- The stern buffers for exceptional impact loading, rail linkspan seatings on the vessels, offset from the axis of girders, a unique linkage to allow for heeling of vessels under loading and unloading of trains.
- The road linkspan seatings on the vessels for exceptional displacements in three modes.
As of 1990, total reliability of operation over 37 years had been achieved.
