Wave conditions inside and outside of a new port and dry dock complex on the Arabian Sea Coast of Oman have been assessed using the 2-dimensional numerical model MIKE21 EMS. The model was used to optimise the entrance channel layout with respect to wave penetration into the port and refine design conditions for the sizing the primary armour on the breakwaters. Initially frequently occurring (operational) conditions were studied to investigate conditions within the port. The study was then extended to include more extreme events to assess wave conditions within the port and along the breakwaters. A range of offshore wave directions was considered in the study to assess the influence of the dredged approach channel on wave conditions within the port. Tests were also undertaken to determine the sensitivity of the selected port layout and approach channel to wave direction.
