Mott MacDonald collaborates closely with our clients to deliver cost-effective and sustainable port solutions, selecting the best location, layout, and configuration of breakwaters to create ideal harbor conditions.

Our coastal engineers employ traditional approaches to breakwater design, supplemented by numerical modeling and (where necessary) physical modeling to plan and optimize breakwater layout and configuration. We maintain an up-to-date knowledge of design developments in the use of rubble mound, berm-type and reef breakwater techniques and in the use of concrete armor units.

Some of our recent breakwater projects include these:

  • Hartlepool, UK. Concept, detailed design, and supervision of construction of a new south breakwater using Accropode concrete armor and the rehabilitation of the existing north breakwater for the new marina
  • Ennore Port, India. Technical and supervision assistance for the construction of the new Accropode armored breakwater
  • Hassyan, UAE. Outline design of rubble mound breakwaters for the intake and outfall to the new power station
  • Ruwais, UAE. Detailed design of rock armored breakwaters to the outfall for the expansion of the Ruwais Refinery
  • Isle of Man, UK. New airport runway extension including a rubble mound revetment seawall and a slope protected with very large rock armor weighing up to 45 metric tons
  • Marine Terminal, Turkey. Pre-FEED study for a harbor formed with rubble mound breakwater to accommodate vessels for exporting sulfur in bulk form, general cargo vessels, and service crafts
  • Pulau Laut, Indonesia. Detailed design and preparation of contract documents for a new marine facility for the loading of gas oil to small coastal barges, including approximately 656 feet (200 meters) of rubble mound breakwater

Many of our projects include the numerical modeling of waves and the study of harbor disturbance to determine the optimum orientation and the design parameters for the breakwater and to assess downtime for operations of the terminals due to the sea conditions within the harbor.

Our application of the latest modeling techniques, using our in-house MIKE 21 technology, guides our recommendations on breakwater and quay alignment and design, and dredging and reclamation needs.
