Breakwater for Service Harbour, Gulf of Aden
The Ash Shihr harbour, on the Gulf of Aden was built by Canadian Nexen Petroleum Yemen (CNPY) in 1992/1993 to provide service support to a Single Buoy Mooring (SBM) used for oil tanker loading. The orientation of the harbour was originally designed to minimize wave agitation at the berth. As a result, the entrance to the harbour was placed on the eastern side to provide shelter from monsoon generated waves traveling from the southwest. Immediately after construction, sediment began accreting in the harbour entrance which necessitated maintenance dredging and sand bypassing to allow continued operations in the harbour. Delft Hydraulics performed a study of sedimentation in the harbour in 1998. The results of this study indicated that the harbour is built on a coastline with substantial longshore sediment transport, with a net rate estimated at 260,000 m3 per year westward. The study also examined solutions to the problem including dredging, relocating the harbour entrance, and constructing a breakwater to the east of the harbour to trap sediment. The sand trap breakwater option was found to result in the lowest maintenance dredging requirements and the lowest total cost. CPNY authorized the detailed design of the sand trap breakwater in 1999. Construction of the breakwater was completed by Yemen based contractors in June 2000. Reports received in April 2003 indicate that the breakwater is performing as expected. Sand bypassing operations are ongoing, but at much reduced levels and acceptable water depths in the harbour entrance have been maintained using a plough dredge.
