Senscient’s ELDSTM cross-duct systems have been selected for Total’s Moho Nord development. The sensors are to be installed on the deepwater Alima floating production unit (FPU).
Moho Nord is the biggest oil project to date in the Republic of Congo and is expected to cost a total of $10 billion. Total E&P Congo is the operator with a 53.5 percent interest. Chevron Overseas (Congo) Limited has a 31.5 percent working interest and the National Oil Company, Société Nationale des Pétroles du Congo holds a 15 percent interest.
The Moho Nord project consists of two developments: Moho Phase 1 bis and Moho Nord. First oil is expected later this year and output is expected to reach 140,000 barrels of oil equivalent a day in 2017. Moho Nord is expected to produce for the next 30 years and Senscient’s technology has been chosen because of the safety, reliability and total cost of ownership advantage it provides.
The project will utilize Senscient ELDSTM Series 1000 Single Laser Open Path Gas Detection system, Cross-Duct & HVAC configuration to detect methane. These sensors provide a clear indication of gas concentrations across the full width of a duct with a genuine response time (T90) of less than 1 second. Unlike traditional point IR or long-nose IR devices, ELDSTM devices are methane specific and operate at a wavelength less prone to water vapour interference, giving greater reliability and performance in challenging environments, such as rain and fog.
