這樣的全集成解決方案能全局把握平臺(tái)的電力系統(tǒng)運(yùn)行,幫助降低平臺(tái)能耗、節(jié)約運(yùn)營成本,并減少風(fēng)險(xiǎn)。西門子專為海工領(lǐng)域設(shè)計(jì)的優(yōu)良產(chǎn)品也完全滿足挪威船級(jí)社對(duì)于防火、防潮、水密性等嚴(yán)格要求。
在傳統(tǒng)的鉆井平臺(tái)建造中,設(shè)備是自下而上如“搭積木”一般疊加起來。而“藍(lán)鯨1號(hào)”的上下船體則是并行建造,然后使用全球起重能力最大的橋式起重機(jī)“泰山吊”一次性完成平臺(tái)大合攏,生產(chǎn)工期大大縮短。半潛式平臺(tái)每遲一天投入石油鉆探,能源公司將蒙受巨大損失。
憑借20160噸的設(shè)計(jì)提升重量,“泰山吊”榮獲吉尼斯世界紀(jì)錄,也成就了當(dāng)今世界最安全、最快捷的大合攏方式。而驅(qū)動(dòng)這一巨型機(jī)械手的變頻器同樣來自于西門子。
“我們選擇和西門子合作是看重了其強(qiáng)大的技術(shù)創(chuàng)新能力以及在全球廣泛的成功經(jīng)驗(yàn)。”煙臺(tái)中集來福士海洋工程有限公司調(diào)試部經(jīng)理候立平表示,“過去幾年間,我們和西門子有非常緊密的合作,而西門子也從來沒有讓我們失望過。”
1879年,西門子在“法拉第號(hào)”海底電纜鋪設(shè)船上安裝了一臺(tái)發(fā)電機(jī)和弧光燈,使其成為世界首個(gè)安裝有電氣系統(tǒng)的船只,由此開啟西門子在海洋工程領(lǐng)域的百年歷史。1886年,西門子建造了世界上首只采用電力推進(jìn)器的船舶。自2005年雙方首次合作以來,西門子已經(jīng)為中集來福士成功交付的6座半潛式平臺(tái)提供動(dòng)力包系統(tǒng)。它們目前正分別在中國南海、挪威北海和巴西海域上作業(yè)。
“定海神針”
“藍(lán)鯨1號(hào)”平臺(tái)借助衛(wèi)星定位和高精度聲吶準(zhǔn)確地找到井口位置。即使面對(duì)颶風(fēng)和洋流,它也能保持穩(wěn)定,成為驚濤駭浪中的“定海神針”,依靠的是全球最先進(jìn)的DP3動(dòng)力定位系統(tǒng)。
與傳統(tǒng)錨泊系統(tǒng)不同,動(dòng)力定位系統(tǒng)基于采集到的推進(jìn)器當(dāng)前轉(zhuǎn)速、方向,以及風(fēng)、浪、流等環(huán)境參數(shù),進(jìn)行精密計(jì)算和分析,由此控制8個(gè)推進(jìn)器的轉(zhuǎn)速和方向,抵消風(fēng)、浪、流對(duì)船體的作用力,達(dá)到精確平衡定位的目的,不會(huì)“隨波逐流”。而“藍(lán)鯨1號(hào)”如果使用錨泊定位,整個(gè)錨鏈覆蓋面積會(huì)有北京六環(huán)內(nèi)區(qū)域那么大,并不經(jīng)濟(jì)可行。the "controlled atmosphere" (CA) fruit and vegetable preservation technology, we developed the logo for the needs of multiple cold storages! Gas analysis device. Because I already have a logo! Experience in refrigeration system, so I feel more comfortable.
Select LOGO!
Previously, PLC was used for this purpose. In terms of price and function, I compared with some products. Because it has both digital and analog inputs, it is just suitable for this kind of application research, and the price is reasonable and the work is stable. And when programming, you can apply the new development and new concepts of relevant majors in recent years without hardware restrictions at any time. So I chose LOGO! And it has been used all the time.
Apply LOGO!
Application Brief
"Controlled atmosphere" (CA) storage technology is to artificially generate an atmosphere environment, such as apples, pears and a variety of vegetables. It is required to be much lower than the oxygen in the atmosphere and higher than the carbon dioxide, so as to make the stored products in a dormant state, so as to reduce the consumption of respiration. It can not
