Port and Quay Wall Infrastructure

We have extensive experience in port and quay wall infrastructure, proven by a strong project portfolio. Our multidisciplinary teams combine expertise in marine, geotechnical, structural, and mechanical engineering and they’re ready to tackle construction challenges from multiple perspectives under one roof.

Every successful project starts with developing an efficient and safe construction methodology. We provide practical solutions, such as piling gates, pile grippers, and skidding systems, while addressing challenges posed by various soil conditions and environmental constraints. One of the examples of our innovative solutions in this field is the Walking Piling Gate, which is proven to increase efficiency, helping to streamline complex projects. All our solutions are tailored to meet the specific needs of each project, ensuring they are cost-effective and timely.

Breakwaters

Breakwater construction involves numerous complexities, from managing uneven seabed to controlling buoyancy and uplift forces. Accurate placement requires precise planning for load-out, transport, and immersion while accounting for waves, tides, and currents. TWD specializes in engineering solutions for caisson installation under complex marine conditions. Our expertise covers every stage of the construction, from load-out and transport to secure placement and stability.

Jetties & Wharves

Constructing jetties and wharves means ensuring precise pile placement while accounting for waves and currents, maintaining stability, and meeting project timelines. Logistical challenges, such as lifting operations and heavy component handling often require specialized engineering solutions. TWD provides optimal solutions according to project-specific circumstances. For some projects, it’s necessary to involve innovative approaches, integrating advanced piling templates, skidding systems, and lifting methodologies to enhance efficiency and precision. In other cases, simpler solutions are enough to to streamline the construction of marine structures. Regardless of the complexity, by combining methodical planning with 3D-integrated engineering, we ensure that jetty and wharf projects are executed with accuracy, reliability, and cost-efficiency.
