Dredging and Reclamation

WSP has an extensive, proven track record of providing advanced solutions for dredging and reclamation projects, including consultation, design and supervision services. Over the past few decades, the dredging industry has faced numerous challenges and is constantly transforming as it adapts to various  economic realities across the continents. Dredging is technologically demanding and often requires a high capital investment early in the project life cycle. It is therefore critical to ensure the most efficient, technically sound and cost-effective solution for the project under consideration.

Traditional dredging activities center on the construction and maintenance of ports and harbors, as well as on the dredging of rivers and navigation channels. Other applications have also become popular in recent years, such as land reclamation, coastal defenses, mineral mining and bespoke structures built for environmental enhancement. Airports, container terminals, industrial developments and residential areas are typical examples where dredging can play a pivotal role in the realization of the project. At WSP, we are proud to offer our clients industry-leading solutions and assistance, as well as design and supervision services across all aspects of dredging throughout the project life cycle.

Breakwaters

At WSP, we have long-standing expertise with the key parameters that affect breakwater performance and a proven track record of delivering breakwater projects across the globe. We know that vessel downtime is a serious issue for a busy modern commercial port, so we employ state-of- the-art optimization techniques to ensure that breakwaters create calm and quiet water for marine traffic. In construction, methodology and materials should be considered to devise a truly optimal solution.

Factors that affect the overall design of a breakwater include the choice of materials, site conditions, construction techniques and the future maintenance regime for the structure. WSP has experience in the design of all sizes of breakwaters, from shore-based groynes or fishtails of several yards in length  to shore-based or offshore breakwaters stretching over several miles. We have developed a robust portfolio of design techniques, including basic design, physical model testing, detailed design and preparation of technical specifications – all tailored to the specific requirements of each new breakwater.

Our in-house geotechnical capability is tailored to individual projects to mitigate the settlement issues that are sometimes encountered during the construction and post-construction stages. We also have relationships with industry-recognized physical modeling laboratories that construct physical models to allow design testing in simulated environments, eliminating guesswork and providing insight into the future performance of a given design in a real scenario. Our team also has a wide range of site supervision experience, from condition surveys and repair design to site supervision – both for new constructions and as part of a remediation or maintenance project.

Intake and Outfall Pipelines

WSP has a proven track record of accomplishment with intake and outfall projects spanning decades, across the full spectrum of projects from cooling water and desalination plants to industrial and domestic effluent outfalls. We also perform conceptualization and design of intake structures and pipelines, including the prediction of effluent dilution, engineering surf zone crossings and the specification of site-appropriate materials. Our expertise enables us to assess hydrodynamic and water quality around intakes and outfalls using oceanographic studies and modeling, assessing the impact on vulnerable habitats and coastal zones, including beach water quality, where applicable.

Water intake from, or discharge to, the marine environment are important engineering considerations. Both are subject to strict environmental legislation to ensure the impact on oceans and inland water bodies are minimized. Traditionally, seawater intake has been primarily used as cooling water for power generation plants, especially in the nuclear sector, and the cooling of buildings in hot and dry climates has also gained popularity in recent years. In addition, the scarcity of drinking water in many arid regions has given rise to desalination and therefore a new use for abstracted seawater.
