Panel Discussion 8:30am – 10:00am in Red Oak Ballroom A/B
Adapting Mooring Design and Standards for the Next Generation of Offshore Platforms
Existing standards in the design and maintenance of offshore mooring is lacking compared to the challenges they face today.
Standards either include insufficient information or direct you to standards that are too broad and open to interpretation. This is
only compounded by the wide variety of mooring materials available. Issues such as Life extension, chain corrosion, inspection and
fatigue are issues that should be addressed more directly as they lead to costly downtime or potential safety issues. What work is
currently being done from an industry standpoint? Are codes such as API, ISO and IOGP intending to make changes to anticipate
future mooring needs?

Lunch Keynote 11:50am – 1:20pm in Magnolia
Blue Oceans: Offshore and Ship Research for Future Maritime Challenges
Dr. Bas Buchner, President, MARIN
As Chairmen of the study ‘Blueprint 2050: The Maritime World Beyond the Horizon’, in his keynote Dr.
Bas Buchner will discuss questions such as: What trends do we foresee in offshore energy and transport
over sea? What are the challenges for offshore oil and gas? Does renewable energy provide new
business opportunities for the offshore industry and its naval architects? Can we use our FPSO
knowledge to develop floating energy hubs for zero emission shipping with Hydrogen, liquid Methane
or Ammonia? Can we develop floating ports and cities to cope with sea level rise and overpopulation?
What is the role of autonomous ship and systems? What is the role of future Naval Architect and Marine
Engineer? What are their tools?
Dr. Bas Buchner studied at Delft University of Technology and graduated in 1991. He joined MARIN and was responsible for many
offshore model test and simulation projects related to mooring, platform response, offloading analysis and wave impact loading. He
specialised in the topics of extreme waves, green water loading and wave impacts. He completed his PhD on the subject of ‘Green
Water Loading on Ship Type Offshore Structures’ (2002). He was Manager of the MARIN Offshore Department from 2000 to 2010 and
was the leader of many Joint Industry Projects (JIP’s) in the Offshore sector. He act as Visiting Professor at the University of Newcastle
upon Tyne and has authored more than 50 papers in the field of Offshore hydrodynamics. Since 2011, he is President of MARIN.

SNAME T&R Panel Session 1:30pm – 3:00pm in Red Oak Ballroom A
Overview of progress for SNAME T&R panels:
OC-8: Wind Technologies – Arjan Voogt
OC-10: Ocean Renewables – Puneet Agarwal
OC-9: Robustness panel
Robustness is not a new concept and many codes already have robustness measures implicit in them. This means that even for standardized designs based on minimal functional requirements and which are code based, there is significant robustness inherited from the codes used. But technology changes, applications differ and no code is perfect, so regardless of any existing measure, care and effort should be expended to identify risks and failure modes that may exist outside the scope or range of any existing code and additional robustness measures introduced if they are found necessary.
Also, simply designing components to meet ever higher performance levels is not an adequate guarantee or measure of robustness because floating production systems are complex with sub-system interactions and co-dependencies that are not always understood or in some cases even identified. Fixing a local component problem can lead to unexpected consequences elsewhere. Instead, robustness must be addressed on both a component and systems level in a balanced approach that results in the highest possible level of overall system robustness.
