日本海洋地球科学技术机构（JAMSTEC）计划使用科学钻井船“CHIKYU”在黑潮高流区进行隔水管钻井作业。在这种大电流区域，隔水管钻井作业将受到涡流诱发振动（VTV）和大电流引起的隔水管倾斜的影响。为了应对这些由大电流引起的问题，JAMSTEC已经开始考虑在CHIKYU在黑潮地区运行期间应用隔水管整流罩。为了确认和评估某些类型的整流罩的性能，已经进行了几次油箱试验。本文将详细介绍CHIKYU的隔水管整流罩和水箱试验结果。
Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has a plan to carry out riser drilling operation in the Kuroshio high current area applying a scientific drilling vessel "CHIKYU". The riser drilling operation in such high current area will be affected by vortex induced vibration (VTV) and inclination of the riser due to high current. In order to cope with these problems caused by high current, JAMSTEC has started to consider applying riser fairings during the CHIKYU's operation in the Kuroshio area. Several tank tests to confirm and evaluate performances on some kinds of fairings have been conducted. In this paper, the detail of the riser fairing for the CHIKYU and results of tank tests will be described.
