Greenhouse gas emissions from offshore facilities are covered by regulations. As a result, offshore facilities will eventually have to restrict emissions of methane by eliminating venting and preventing fugitive emissions. In addition, many European companies participated in the Certified Emission Reduction Project. When methane gas is released into the atmosphere, it becomes a greenhouse gas 21 times more potent than carbon dioxide. Offshore, it is frequently compressed and used on pneumatically operated devices, which can leak and emit fugitive methane. Other offshore environmental hazards involve potential leaks from pipelines or storage tanks. All environmental emissions, whether they are liquid or vapor, represent a financial loss.
Global Exergy environmental solutions generally pertain to methane loss prevention or recovery, as well as monitoring for liquid spills. Fisher Controls features low-emission control valves and controllers to prevent the escape of methane gas used as a pneumatic medium. Global Exergy also use vapor recovery systems for compressors. Level monitors on storage tanks can provide overfill protection and identify systems that are leaking liquids into the water. corrosion sensors also contribute to leak prevention. CSI online vibration monitors can identify leaking seals on pumps, compressors, and other rotating equipment. Wireless monitors provide cost-effective protection on process skids, issuing warnings remotely of gas or liquid losses as necessary. The Wireless Liquid Hydrocarbon Leak Detector is a reliable monitor for use on tanks, lines, and valves in remote locations where running signal wires would be expensive or impossible. Solutions must often be tailored to a specific platform.
