德州奧斯汀2008年2月25日消息，艾默生過程管理公司已經(jīng)成功將其無線自組織場域網(wǎng)應用在Grane離岸平臺上，用于監(jiān)測井口環(huán)空壓力和熱交換器壓力。Grane平臺位于挪威海卑爾根海岸，由StatoilHydro運營。 艾默生的自組織無線網(wǎng)孔技術(shù)是適合于無線技術(shù)應用的理想選擇，能夠在艱苦環(huán)境中使過程搖控監(jiān)測和控制延伸到各個區(qū)域。艾默生相信其在Grane平臺上應用的網(wǎng)絡是歐洲第一個安裝離岸無線技術(shù)的提供商。 StatoilHydro Grane運營處Geir Leon Vadheim說：“應用在我們離岸平臺上的新技術(shù)是非?？煽康?。我們也會考慮由無線網(wǎng)關收集的數(shù)據(jù)如何整合到第三方系統(tǒng)中。作為其結(jié)果，一體化就顯得很容易，智能無線傳送器的性也已超過了我們的期望。” 井口地區(qū)遍布金屬管，金屬管道與其它金屬障礙物一起或在上方或是下方。盡管是在非常有挑戰(zhàn)的環(huán)境中，當傳送器被供以動力后，設備就能發(fā)現(xiàn)網(wǎng)關，網(wǎng)就能被建起來。當添加新設備后，也能很快很方便的加入網(wǎng)中。在操作時期，信號加強和連貫性會變得很通暢。 無線網(wǎng)絡可實現(xiàn)連續(xù)的壓力監(jiān)測，排除每日所需的井口參觀和每日的手動記錄。連續(xù)監(jiān)測可使特殊的指示數(shù)被輕松識別，在其變成嚴重問題之前進行調(diào)查予以更改。 智能無線網(wǎng)絡應用的平臺，包括22個替代傳統(tǒng)規(guī)格儀器的無線Rosemount®壓力傳送器，十個安裝在井口用于測量環(huán)空壓力的壓力傳送器，另外十二臺壓力傳送器監(jiān)測入口壓力和熱交換器上的壓降。在控制室中，每一個傳送器收集的數(shù)據(jù)都會傳遞給操作員。利用測量適配器進行安裝，安裝就會變得很輕松很容易，無線網(wǎng)送被安裝在了平臺一邊的過程區(qū)域，此區(qū)域正好可監(jiān)視井口狀況。 Geir Leon Vadheim說：“我們非常高興艾默生智能無線網(wǎng)絡在如此具有挑戰(zhàn)的環(huán)境中仍能具備很高的性能。接下來是一個短期培訓計劃，我們的儀器工程師對于在網(wǎng)絡中添加需要的無線設備非常自信，這些與兩天的傳統(tǒng)式接線安裝時間相比，只需要兩小時，可大幅降低安裝時間?！? 在此次成功安裝后，StatoilHydro計劃在其它離岸平臺上安裝艾默生無線智能傳送器。 [FONT=times] original text [/FONT] [font=times] Emerson’s Smart Wireless solutions improve wellhead and heat exchanger monitoring on StatoilHydro offshore platform [/font] [font=times][Color=#708090]AUSTIN, TEXAS （February 25, 2008） – Emerson Process Management has successfully applied its wireless self-organizing mesh field network to monitor wellhead annular pressure and heat exchanger pressures on the Grane offshore platform. The Grane platform is operated by StatoilHydro and is stationed in the Norwegian Sea off the coast of Bergen, Norway. Emerson‘s self-organizing wireless mesh technology is ideally suited to the application of wireless technology, enabling remote monitoring and control of the process in difficult to reach areas. Emerson believes that the network on the Grane platform is the first offshore wireless installation in Europe. "We had some concerns that this new technology would work reliably in the harsh environment of our offshore platform," said Geir Leon Vadheim, Instrument Lead, Grane Operations, StatoilHydro. "We also needed to address the issue of how we would integrate the data gathered by the wireless gateway into a third party system. As it turns out, the integration was easy and the performance of the Smart Wireless transmitters has exceeded our expectations." The wellhead area is crowded with metal pipe work, metal walkways above and below, together with other metal obstructions. Despite the challenging environment, as each transmitter was powered up, the devices found the gateway, and the mesh was established. As new devices were added, they quickly and easily joined the mesh. Signal strength and consistency during the operational period has been excellent. The wireless network enables continuous monitoring of pressures and eliminates the need for daily visits to the wellhead to manually record gauge readings. Continuous monitoring enables unusual readings to be identified earlier and action taken to investigate and rectify faults before they develop into serious problems. The Smart Wireless network on the platform includes 22 wireless Rosemount® pressure transmitters which replace traditional gauges. Ten pressure transmitters are mounted on a wellhead and used to measure annular pressure. A further twelve pressure transmitters monitor inlet pressure and pressure drop over the heat exchanger. Each transmitter relays data back to the operator consoles in the control room. Installation was quick and easy with a gauge adapter fitting used to allow a direct "screw in" replacement. A wireless gateway was mounted outside the process area on one side of the platform, at a height where it oversees the wellhead area. "We are delighted with the performance of the Emerson Smart Wireless network in these challenging conditions," said Geir Leon Vadheim. "Following a short training program, our instrument engineers are very confident about adding more wireless devices to our installation as required. These typically take around two hours to install compared with up to two days for a conventional wired unit." Following the success of this installation, StatoilHydro is planning to install Emerson Smart Wireless transmitters on other offshore platforms that it operates in the area.[/color][/font]
