Rina Develops CNG rules and guidelines
International classification society RINA has used its offshore gas expertise to develop rules and guidelines for the exploitation, transport and storage of Compressed Natural Gas. Angelo Lo Nigro, Oil and Gas Manager, RINA, says, “Compressed natural gas offers an alternative way to move natural gas where volumes do not support a liquefaction plant or a pipeline. A significant amount of the world’s gas reserves fit these criteria. As environmental pressure makes it more difficult to flare gas CNG transportation is a useful alternative to expensive re-injection into the field. “There are a number of potential systems for CNG carriers, but to date no solution has been implemented. We have worked with industrial partners and drawn on our own experience with LNG offshore to set up rules and guidance for the approval in principle of pressure vessels for use in a marine environment and for the conceptual design of various CNG carriers.”
