Breakwater at Bounty Bay, Pitcairn Island

Breakwater, Pitcairn Island


British Government Foreign and Commonwealth Office



This project required preliminary design for a breakwater at Bounty Bay, Pitcairn Island. Pitcairn Island’s coastline is rugged and faces in a north-easterly direction out to open ocean.

Bounty Bay is the primary landing point for access onto Pitcairn Island. With no off-shore islands or reefs to provide protection from waves and such, the bay is exposed to very high energy conditions.

Following our earlier work, involving constructing Pitcairn Island’s first sealed road and repairing the landing jetty, design work for a proposed breakwater was completed to enable all weather access onto the island.
