Abstract:

The design and construction of the wharf for 250,000 DWT bulk carriers is discussed in this paper. The terminal project was carried out on fast-track, 23 month schedule, with construction commencing before design was complete. Construction of the shiploader foundations was commenced before contracts for the shiploader had been awarded, requiring the accommodation of changes to details and construction schedule and the interfacing of several contractors on the wharf before a fixed connection to shore was complete. Up to seven floating cranes were at work on site at the one time. Site conditions, including highly metamorphosed weak bedrock overlain by soft marine silts, exposure to Pacific storms, and an 8 metre tide range, resulted in innovation in several areas of the design, and required that the construction method be understood and developed in parallel with the design. The paper provides details of the geology of the site, and discusses the design concept, innovative details of the design, contractual arrangements, and the construction technique and special equipment used.
