Structural-geotechnical Interaction of Moorings of Floating Systems

Anchoring systems are key components of the support structure of floating platforms and their design includes many opportunities for innovation and challenges to delivering reliable performance. Mooring systems are known in the oil and gas industry to be a potential source of reduced reliability, and implementation of mooring systems for floating platforms will require deeper understanding of the interaction of structural and geotechnical behavior. Among the challenges to the design of new mooring systems, the following are prioritized for discussion in this panel: cyclic loading and soil uncertainty, optimization of mooring architecture, and mooring and anchor design for intermediate and shallow water depths.

Panelist #2: Thomas Langford (NGI)

Thomas Langford is Director for Offshore Energy at the Norwegian Geotechnical Institute in Oslo, with 20 years’ of experience within the offshore industry, with a technical focus on the characterisation of seabed soils and the design of anchor and foundation systems for offshore facilities in water depths from 10 m to over 2000 m. Mr Langford is an active member of the ISO WG10/API RG7 committee for offshore geotechnical issues and also serves on the SUT/OSIG committee in Europe. As a practicing engineer and researcher, he has worked extensively on issues related to offshore wind and anchoring systems. He was involved in the design and installation of 32 suction anchors in the Massachusetts Bay LNG import terminals, and has otherwise been responsible for offshore project deliveries on 6 continents. Mr Langford is a strong supporter of the offshore wind industry in the USA, and keen to see the acceleration of floating wind technology. He sees great potential in the optimization of mooring systems, and anticipates large cost reductions in the market segment based on developments in the supply chain and high quality research activities across academia and the industry.
