FSI/SMMI/LR Sloshing Assessment of Membrane LNGS

Mr. Nigel White, Technical Manager for hydrodynamics in Lloyd’s Register’s Structural Analysis and Hydrodynamics team
nwhite21st November Boldrewood Innovation campus B175 Seminar Room 1025 (entrance through b176) Time: 11:00-12:30 
We are limited to 120 spaces for both University of Southampton and LR attendees so prompt attendance is recommended.

Abstract:
Lloyd’s Register is responsible for the development, implementation and maintenance of standards for the design, construction and operation of ships and offshore units. These standards, or ‘Rules’ are supplemented by additional verification procedures which are often assessed using advanced structural analysis techniques or similar direct calculation programs.
One example of this is the assessment of the strength of the LNG cargo containment system to resist sloshing actions, the assessment of the design sloshing loads and the assessment of the structural response and capacities are very complex and a simple definitive procedure is no longer applicable. .
Lloyd’s Register “Sloshing Acceptance Guidance Document for Membrane Tank LNG Operations” gave recommended design methods for the assessment of the cargo containment system.  This talk reviews some of the issues associated with the development of this document, related research tasks and also the processes followed by Lloyd’s Register in the design appraisal of LNG cargo containment systems and the recent application to FLNGs.
Biography
Technical Manager for hydrodynamics in Lloyd’s Register’s Structural Analysis and Hydrodynamics team which looks after research and development issues. My role is to look after the research programme for the development of hydrodynamic expertise and capabilities of Lloyd’s Register covering ship motions, hydroelasticity, sloshing, dynamic load application, etc. for all ship types. As such I support Lloyd’s Register’s Classification and Plan Approval offices worldwide on hydrodynamic related issues.
I joined Lloyd’s Register 16 years ago and have been one of the principal engineers on many projects including LR’s Naval Ship Rules, IACS Common Structural Rules for Tankers, IACS Harmonised Common Structural Rules for Oil Tankers and Bulk Carriers. I was the lead author of LR’s Sloshing Assessment Guidance Document and have been involved in many sloshing related studies and approval of all recent membrane tank LNG ships with respect to sloshing issues including the QFlex and the first QMax ships. I was also the lead author on the 2014 released whipping and springing assessment procedure for container ships.
Prior to Lloyd’s Register, I worked for Burness, Corlett and Partners in charge of their computational analysis group for 11 years. I graduated from the University of Southampton in 1978 with a Ship Science degree.
