2Installation and operational effects of a HVDC submarine cable in a continental shelf setting: Bass Strait, Australia显示文摘Despite the many submarine telecommunications and power cables laid world-wide there are fewer than ten published studies of their environmental effects in the refereed literature.This paper describes an investigation into the effects of laying and operating the Basslink High Voltage Direct Current(HVDC)cable and its associated metallic return cable across Bass Strait in South East Australia.Over more than 95%of its length the cable was directly laid into a wet jetted trench given the predominantly soft sediments encountered.Underwater remote video investigations found that within two years all visible evidence of the cable and trench was gone at over a third of the transects at six deep water sites(32-72 m deep).At other deep water transects the residual trench trapped drift material providing habitat for the generally sparsely distributed benthic community.Diver surveys at both of the near shore sites(<15 m deep)on the northern side of the Strait also found the cable route was undetectable after a year.On the southern side,where the cable traversed hard basalt rock near shore,it was encased in a protective cast iron half shell.Ecological studies by divers over 3.5 years demonstrated the colonization of the hard shell by similar species occupying hard substrates elsewhere on the basalt reef.Magnetic field strengths associated with the operating cable were found to be within 0.8%of those predicted from theory with strength dropping rapidly with distance from the cable.Beyond 20 m the field was indistinguishable from background.John Sherwood Scott Chidgey Peter Crockett David Gwyther Percival Ho Simon Stewart David Strong Bob Whitely Alan Williams 2016Journal of Ocean Engineering and Science2016,1,4:1

5金属粘结层厚度对大气等离子喷涂陶瓷涂层粘结强度的影响显示文摘应用于金矿开采业中的球阀在服役过程中由于受颗粒磨损,泥浆侵蚀,涂层粘结力/内聚力或者剪切力不高而发生破坏。修复价格昂贵耐腐蚀合金(CRA)球阀典型的工艺是:对合金基体进行钨极惰性气体保护焊(GTAW),球阀表面打磨,以及利用大气等离子喷涂(APS)技术在球阀表面制备陶瓷热喷涂涂层(TSC)。另一种修复方法是利用机加工使球尺寸减小,然后在陶瓷层下面沉积一层较厚的金属粘结层(MBC)以保证球阀的原始尺寸。本文研究了按照ASTM C633标准检测大气等离子喷涂陶瓷涂层的结合强度是否与超音速火焰喷涂的NiCrMo(哈氏合金)金属粘结层的厚度极限有关。实验所用的基体材料为三种耐腐蚀合金(CRA):钛G12,铬镍铁合金625以及2507双相不锈钢,在这三种基体表面沉积了8种不同厚度的金属粘结层。金属粘结层的厚度分别是:0.0015英寸,0.005英寸,0.015英寸,0.030英寸,0.045英寸,0.060英寸,0.075英寸以及0.090英寸。利用大气等离子喷涂工艺在上述8种不同厚度的金属粘结层表面喷涂厚度为0.015英寸的Cr_2O_3,Cr_2O_3-Al_2O_3和TiO_2这三种陶瓷涂层。对样品做了如下测试:涂层结合强度(ASTM C633)测试,金相显微组织分析(ASTM E1920),涂层孔隙率(ASTM E2109方法 B)测试。John Barr Christopher Estrada Nelson Victoria Bob White Jerome Harrison 贾芳(译) 原慷(校) 2016热喷涂技术2016,8,3:0
6随钻地层评价新进展显示文摘准确及时地进行地层评价是石油勘探开发的一个重要方面。过去,作业者不得不在随钻测井仪实时测量的优势与电缆地层评价技术更加全面的优势之间寻求平衡。一种新型综合随钻测井仪结合功能强大的解释软件,建立了新的安全高效标准,而且降低了地层评价的不确定性。Bob Adolph Chris Stoller Mike Archer Daniel Codazzi Tamir el-Halawani Patrick Perciot Geoff Weller Mike Evans Jeff Grant Roger Griffiths Don Hartman Gerald Sirkin Makoto lchikawa Graham Scott lan Tribe David White 2006国外测井技术2006,21,4:0
