Emerson Process Management s wireless temperature transmitters have been installed at BP Exploration s Dalmeny onshore terminal. Once in place, the new wireless network confirmed that the existing tank protection system is capable of providing the necessary protection.
Dalmeny, located near Edinburgh, UK, has the capacity to store about four million barrels of stabilized crude oil from the Forties oil field. Eight interconnected storage tanks, 40-50m in diameter, are used to regulate the flow of oil between production wells and the tankers or pipeline that will transport it to the refinery.
BP was already measuring oil temperature at the side of the tanks. But, because of the size of the tanks there was a concern that there could be a significant difference between temperatures at the edge of the tank and at the center. A number of measurements were therefore required to confirm any differences in temperature. This presented a challenge because the tanks needed to remain in use, making installation of temperature probes impossible.
An out of service tank with no existing temperature measurement in place presented the perfect opportunity to install the necessary instrumentation. However, there was no cabling infrastructure in place for this specific tank so if BP had installed wired transmitters, they would have also had to install a cable recoil system to cope with the floating roof. This would have cost over 15,000.
Wireless presented a cost effective alternative, and having successfully applied Emerson s Smart Wireless technology to monitor wellhead annular pressure at its Wytch Farm site, BP was confident that it would be suitable for this application.
