United Electric Controls introduced its WirelessHART Vanguard Gas Detector, which can monitor presence of harmful gases in offshore installations for more than 5 years without a battery replacement (Fig. 1). The detector interfaces with the existing offshore platform network to provide continuous, economical detection of hydrogen sulfide and methane gases. Continuous monitoring of the levels of these gases is vital to protect workers, but the cost of wiring new gas-measurement points on an offshore platform can easily exceed USD 50,000 per device. Wired sensing is especially prohibitive on offshore facilities. Wireless technology, however, reduces continuous monitoring costs by up to 90%. This makes it affordable to deploy sensing devices at more locations, detecting leaks that a limited number of wired units might not notice. Contributing to the value of the Vanguard detector is its use of lithium battery technology which, combined with low-power components and advanced power modules, can extend battery life well beyond 5 years. Wireless devices signal a gateway that can be connected to a fire- and gas-control system, fire station, distributed-control systems, or a programmable-logic-controller host for alarming. The wireless signals may be designed using any network protocol, but standard open protocols such as that used in WirelessHART have specific advantages.
