With the global LNG market
forecast expected to double in size over the next decade the industry is showing particular interest in the development of offshore LNG installations, which is believed by some to be a safer way for LNG production, storage and distribution. This new breed of LNG FPSOs (FLNG) will combine gas ship containment
and marine systems with onshore type LNG processing equipment
and operate in an offshore environment.
Gael Lewis, Lloyd’s Register Director of Energy & Transportation said: “The prospect of the industry designing, building and installing such installations has prompted Lloyd’s Register of Shipping to prepare and publish draft ‘Guidance Notes for Classification of Offshore LNG Production
& Storage Installations’ and invite comments from those in the industry on the draft. When finalised the document is intended to provide comprehensive guidance to designers, operators and Lloyd’s Register surveyors regarding classification and certification for steel or concrete floating installations and gravity based structures. It will not replace requirements given in the relevant Lloyd’s Register Rules and Regulations but is intended to support and complement them.”
The draft guidance notes have focused upon certain technical aspects relating to FLNG design
including class notation, hull, mooring and topsides aspects, LNG processing and containment, safety and risk based assessments, fabrication, testing and in-service surveys.
