Coasts and Marine Structures- Industry Experts Key Topic Discussion


Published on

In this Key topic discussion, we’ve collated the responses from three industry leaders who have provided their opinions and thoughts on the current state of the coasts and marine structures field. Here, they share what they believe are the future and progressive technologies and what they feel are the best practices to their work.

Coasts and Marine Structures- Industry Experts Key Topic Discussion

  1. 1. Key Topic Responses from Industry experts Coasts and Marine Structures 2011 02 9229 1000 @ Construction_IQ
  2. 2. <ul><li>For Coasts and Marine Structures 2011, Construction IQ interviewed </li></ul><ul><li>three prominent speakers to discuss key areas in the coasts and </li></ul><ul><li>maritime construction industry. </li></ul><ul><li>The three speakers we interviewed were: </li></ul><ul><li>Phil Davies - Principal Engineer at Golder Associates </li></ul><ul><li>Alan Betts New South Wales Regional Manager and Australia Maritime Manager at URS/Scott Wilson </li></ul><ul><li>Gregory Riordan, Technical Director and Design Manager - Port Botany Expansion, Hyder Consulting </li></ul><ul><li>We’ve collected a selection of their responses. For their full interviews, </li></ul><ul><li>please click here . </li></ul>
  3. 3. <ul><li>Construction IQ asks: </li></ul><ul><li>What do you foresee to be the </li></ul><ul><li>progressive and future technologies </li></ul><ul><li>involved in the design of marine </li></ul><ul><li>structure facilities in the near future? </li></ul><ul><li>And why is this so? </li></ul>
  4. 4. <ul><li>Phil Davies - Principal Engineer at Golder </li></ul><ul><li>Associates </li></ul><ul><li>In the Port Botany expansion, we used the following technologies: </li></ul><ul><li>2D and 3D with PLAXIS software, </li></ul><ul><li>We also trialled reclamation ground improvement techniques such as vibrocompaction and dynamic compaction. </li></ul>
  5. 5. <ul><li>Alan Betts New South Wales Regional Manager and Australia Maritime Manager at </li></ul><ul><li>URS/Scott Wilson </li></ul><ul><li>Most of this rests upon efficient facilities. Right now we’re looking at automation – ranging from automation within containers and stevedoring terminals. For example, Patrick’s at Port Botany, there is an automated terminal there. </li></ul><ul><li>We can also expect more of automate rail operations , as well as the use of shore power to more effectively use resources. </li></ul><ul><li>In Porthedland, they use suction pads instead of ropes, which equates to increased efficiency. </li></ul><ul><li>There’ll also be greater use of keel clearance systems . This increases the time slot for vessel oepratiosn to navigate channels and they minimise the amount of dredging you do when you’re planning a port operation. We are probably going to see more cathodic or impressed current technologies for concrete too, as well as more plastics. </li></ul><ul><li>The LNG terminal at Costa Azul in Mexica, whereby the structure can be removed at the end of the project life also demonstrates a trend towards greater implementation of the infrastructure removal . </li></ul>
  6. 6. <ul><li>Gregory Riordan, Technical Director and Design Manager </li></ul><ul><li>– Port Botany Expansion, Hyder Consulting: </li></ul><ul><li>Refinement of quay structure design through more advanced structural and loading analysis (e.g. PLAXIS, Strand and advanced mooring analysis), </li></ul><ul><li>Design to accommodate larger vessels and associated quay cranes, </li></ul><ul><li>Increased automation </li></ul><ul><li>Supply of shore power to vessels as they have started doing at ports internationally including the Port of LA. </li></ul>
  7. 7. <ul><li>Construction IQ asks: </li></ul><ul><li>What are the best practices when it </li></ul><ul><li>comes to the planning and construction </li></ul><ul><li>of marine structures? </li></ul>
  8. 8. <ul><li>Phil Davies - Principal Engineer at Golder </li></ul><ul><li>Associates </li></ul><ul><li>Needless to say, innovation should always be encouraged , and sometimes, the best results we’ve had were when we worked closely with the clients. It’s when clients and contractor engaged closely in working through solutions do we witness innovative ideas. </li></ul><ul><li>It is also important to not over specifying certain issues , which is a trap that can be common in such projects – this stifles innovation and may result in requirement conflicts. To combat this, it is a good idea to have a dispute resolution board , as what we have in Port Botany. I think this really helps the system and helps prevent any sort of adversarial conditions. </li></ul>
  9. 9. <ul><li>Alan Betts New South Wales Regional Manager and Australia Maritime </li></ul><ul><li>Manager at URS/Scott Wilson </li></ul><ul><li>Ensuring clever designs are one of the key parts, and this can be done by side testing, which has proven useful in our design in Costa Azul, Mexico </li></ul><ul><li>We are also going to see more precasting and fabrications of elements on shore. For example, the Port Botany expansion project uses a significant amount of precast and concrete elements </li></ul><ul><li>I also expect to see more modular construction too, such as the ones used in South Hook in Wales and some other jobs for LNG terminal. </li></ul><ul><li>Finally, we’re going to see more processing and materials for recycling and that happened in Port Botany and South Hook. In regards to South Hook, there were modifications of construction techniques, and since there were extensive areas of coral, the construction program needed to be modified and varied to accommodate this. And it’s actually a very clever technique. </li></ul>
  10. 10. <ul><li>Gregory Riordan, Technical Director and Design Manager </li></ul><ul><li>– Port Botany Expansion, Hyder Consulting: </li></ul><ul><li>It is critical to determine realistic load cases and to understand soil/structure interaction when refining structural design. </li></ul><ul><li>You should also keep it simple and make sure structures are more or less uniform – the modular precast construction method worked well as Port Botany Expansion. </li></ul><ul><li>Companies should also try to complete as much work on land as possible (it’s safter, and cheaper) and carefully plan interaction with shipping and recreational vessels </li></ul><ul><li>You must also have the flexibility to work on a number of work fronts to reduce potential for delays etc </li></ul>
