Our Expertise
Port Infrastructures
Port infrastructure projects, such as the construction of jetties, piers, quays, and wharves, face various challenges during the piling process. Issues like subsurface variability, pile alignment difficulties, and environmental constraints, including waves, currents, and wind, can significantly affect installation timelines and project costs. Additionally, technical problems such as interlock failures and tolerance inconsistencies complicate the process further. Addressing these complexities requires precision, innovative tools, and expert planning.
TWD leverages its knowledge and expertise to provide tailored solutions that optimize piling operations. Through innovative designs such as piling gates, pile grippers, and skidding systems, we ensure precise alignment and efficient handling of piles. By integrating smart template tools and drive & control systems, we are able to reduce installation time, minimize manual operations, and enhance crane utilization. Notably, TWD’s “Walking Piling Gate” demonstrated a double increase in efficiency, showcasing its potential to transform challenging port infrastructure projects into streamlined successes.
Immersed Tunnels
Immersed tunnel projects can be particularly challenging due to their technical complexity and demanding site conditions. Key issues include managing geotechnical variability, maintaining structural integrity under water pressure, and ensuring stability during the temporary immersion process. Environmental factors such as water currents, tides, and precise placement of tunnel segments can complicate logistics, especially when heavy machinery is involved.
TWD applies its specialized expertise to overcome these challenges, using advanced marine and dynamic analysis tools, structural techniques, and 3D conceptualization. Our solutions include:
- Mooring and towing analyses
- Ballast optimization
- Subsea lifting tools
- Stability assessments for barges and tunnel elements
Bridges
Building suspension bridges can be very demanding, particularly during the installation of prefabricated segments. These operations demand careful evaluation of stability and lifting processes while managing environmental factors such as wind and water dynamics. Precision is essential to ensure safe and efficient construction. With a focus on operational safety and efficiency, TWD supports the seamless placement of bridge segments, facilitating the successful assembly of these impressive long-span structures. Our services include:
- Design of piling frames/templates
- Lifting analyses and design of tailored lifting frames
- Bridge-launch equipment / launching girders
- Tailored gantry cranes
Outfalls / Cofferdams
Cofferdam and outfall installations demand careful management of water pressure, soil conditions, and structural stability to create safe, dry workspaces. Challenges include maintaining stability against currents, ensuring watertight seals, and precisely positioning structures in variable conditions.
TWD delivers tailored solutions for these projects, using knowledge in marine and structural engineering. Services include stability analyses, watertight seal designs, and efficient installation procedures. With advanced tools and innovative methods, we can ensure safe, precise, and reliable cofferdam and outfall construction in even the most demanding environments.
Caissons
Caisson installation in marine environments 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 provides customized solutions to address these needs, leveraging expertise in marine and civil engineering. Our services include:
- On/Offloading analyses and design of skidding systems
- Barge mooring, ballasting and stability analyses
- Robust seafastening solutions
- Third party verifications and on-site coordination
