Cook Strait Ferry Terminal, Picton
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.
Construction of the terminal was difficult. There were severe site constraints. Existing service needed to be maintained without interruption during the construction of Number 2 berth and an overpass over highway and rail yards needed to be erected. The conversion of Number 1 berth included lengthening the longarm and replacing the linkspan and gangways and Number 2 berth was subsequently converted for larger vessels. Dominant factors were urgency, economy, the limitations of the port itself and the desirability of high standards of public amenity.
As of 1990, total reliability of operation over 37 years had been achieved.
- Lithe 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.
