Bureau Veritas has issued new notations and guidelines for the construction and conversion of existing liquefied natural gas (LNG) carriers to floating storage regasification units (FSRUs) and floating LNG gas storage units (FSUs).
According to BV, floating gas terminals provide operational flexibility, reduce timescales from concept to operation, and improve cost effectiveness of storing and operating with LNG, compared with on-shore terminals. The new conversion guidelines advise the LNG industry on how to address issues that either will or may arise during the conversion of LNG carriers into FSRUs or FSUs.
The new notation FSU-LNG provides the specific classification requirements including structure and safety aspects for floating units dedicated to store LNG that are neither designed nor built to transport LNG
The notation Liquefied Gas Carrier – FSU provides specific classification requirements including structure and safety aspects for floating units dedicated to store LNG that are also designed and built to transport LNG.
The guidelines LNG Carrier Conversion to FSRU or FSU address the requirements for conversion of existing LNG carriers to either floating LNG gas storage units fitted with a regasification plant (FSRUs) or floating LNG gas storage units (FSUs).
According to BV there are more than 20 LNG carriers presently in laid-up condition, some of which can be converted to floating terminal applications.
Matthieu de Tugny, COO, Bureau Veritas, Marine & Offshore commented: “With growing interest in floating gas terminals, working with industry stakeholders, we are providing the rule framework and guidance necessary to develop both FSRU and FSU terminals – both for newbuildings and conversions.”
