In cooperation with many departments, a 49-day marine test in water depths of 1365 m and 1252 m was completed on the \u201cHYSY-981\u201d ocean oil drilling platform. No welding and pasting were used when the sensor was installed on risers. Therefore, the installation is convenient, reliable and harmless to risers. The continuous, reasonable, time-consistent data obtained indicates that the sensor worked normally under water. In all detailed working conditions, the test results show that the sensor can do well in reflecting stresses and bending moments both in and in magnitude. The measured maximum stress is 132.7 MPa, which is below the allowable stress. In drilling and testing conditions, the average riser stress was 86.6 MPa, which is within the range of the China National Offshore Oil Corporation (CNOOC) mechanical simulation results.<\/jats:p>","DOI":"10.3390\/s151129648","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T12:08:12Z","timestamp":1448366892000},"page":"29648-29660","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Study and Test of a New Bundle-Structure Riser Stress Monitoring Sensor Based on FBG"],"prefix":"10.3390","volume":"15","author":[{"given":"Jian","family":"Xu","sequence":"first","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Dexing","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Chuan","family":"Qin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Yajun","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Leixiang","family":"Sheng","sequence":"additional","affiliation":[{"name":"Key Lab of Deepwater Engineering CNOOC Research Institute, Room 808, CNOOC Plaza, Taiyanggong South Road 6#, Chaoyang District, Beijing 100028, China"}]},{"given":"Xiangyun","family":"Jia","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Yang","family":"Bai","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"},{"name":"The Key Laboratory of Space Applied Physics and Chemistry, School of Science, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Xiaohong","family":"Shen","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Haiyan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, 127 West Youyi Road, Xi\u2019an 710072, China"}]},{"given":"Xin","family":"Deng","sequence":"additional","affiliation":[{"name":"Zhanjiang Western South China Sea Oil Survey and Design Co., Ltd., Nanyou Engineering Building, Nandiao Road, Zhanjiang 524057, China"}]},{"given":"Liangbin","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Lab of Deepwater Engineering CNOOC Research Institute, Room 808, CNOOC Plaza, Taiyanggong South Road 6#, Chaoyang District, Beijing 100028, China"}]},{"given":"Shiquan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Lab of Deepwater Engineering CNOOC Research Institute, Room 808, CNOOC Plaza, Taiyanggong South Road 6#, Chaoyang District, Beijing 100028, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Constantinides, Y., Chen, J.-H., Tran, L., Enuganti, P., and Campbell, M.
