DORSET, UK -- Groveley Detection has built a system to monitor methane levels within seven seabed risers on FPSO Triton in the North Sea.
Wood Group engineers approached Groveley to design the system, which they based around seven Simtronics GD10 infrared flammable gas detectors, each with 0-100% vol methane, to be fitted into pipe risers onTriton.
The sensors will connect to a Groveley-designed data logger within a flameproof cabinet. Data will then be routed to a PC where the information is downloaded and recorded.
Sensors and purpose-built mountings were manufactured in stainless steel and flanges were pressure-rated to maintain the integrity of the risers.
The GD10 infrared gas detectors use silicon-based, solid-state infrared sources. These sources are so stable that once a detector is factory calibrated, it needs no adjustment on site during commissioning or through its working life, the company says.
