§ 01 — Overview

A deep-water quay extension delivered between two shipping seasons

The challenge

A deep-water quay extension that had to be built between two shipping seasons.

Engineering approach

Combi-wall piles were driven from a jack-up barge while the deck was precast on land, so marine and land works ran in parallel.

Execution

The quay was handed back to the port operator before the first vessel of the new season was due.
