How does PND address the challenges of designing in severe environmental conditions?
PND designs for high seismic loads, extreme tidal fluctuations, high-velocity winds, and low temperatures, ensuring strong, reliable structures.
What makes PND’s float design unique?
We design concrete floats, timber floats, pipe floats, and ultra-high-molecular-weight tub and pipe floats. Each design considers the end users of the facility and the long-term maintenance demands, ensuring our design services provide the longest service life possible with the lowest maintenance costs.
What are the benefits of PND’s OCSP bulkheads?
This patented solution provides strong platforms for heavy-lifting equipment in difficult seismic, ice, and current conditions, supporting designs in a multitude of waterfront soil and weather conditions.
How does PND support the cruise industry?
PND plays a crucial role in supporting the cruise industry by delivering expert engineering and design services tailored to the unique challenges of maritime infrastructure. PND develops robust port facilities, docking systems, and waterfront structures, ensuring cruise lines have safe, efficient, and aesthetically pleasing infrastructure to accommodate their ships and passengers. PND specializes in designing facilities with difficult conditions such as logistically challenging locations and/or terrain. Our comprehensive approach includes feasibility studies, structural design, project management, and construction support, all aimed at enhancing the operational efficiency and environmental sustainability of cruise operations. By leveraging our deep industry knowledge and innovative solutions, PND helps cruise lines provide memorable and smooth experiences for travelers while optimizing port and terminal functionality.
Can PND assist with the entire process from planning to construction?
Yes. PND handles everything from initial planning and securing funding to design and construction support services for your waterfront engineering project.
What types of docks and piers has PND designed?
PND has designed over 200 docks and piers in the last decade alone, from fixed and floating docks to OCSP docks, each tailored to support our clients’ needs. PND has provided design, retrofit, and/or rehabilitation on over 1,000 waterfront engineering projects worldwide in our 45-year history.
How does PND ensure the longevity and durability of their waterfront structures?
PND uses advanced materials and innovative designs, such as SPIN FIN piles, to withstand environmental stresses and provide long-lasting, low-maintenance structures. For instance, a SPIN FIN pile can absorb many times more energy than a smooth pile through its ability to increase load capacity as the pile is moved (pulled or pushed). A SPIN FIN pile acts similarly to a screw, while a traditional pile is similar to a nail.
What kind of waterfront projects has PND completed in the past?
PND has successfully completed numerous projects, from small community docks to large commercial port facilities, across both coastal and inland waterways for a variety of industries.
