Marine Geology No. 17 Vessel and its application in coastal geological survey

Abstract:

Coastal geological surveys play a pivotal role in understanding resource distribution and ecological conditions in China''s coastal regions， promoting urbanization development， ensuring sustainable economic growth， and addressing frequent natural disasters. The Marine Geology No. 17 Vessel， independently designed and constructed by China， is a small-displacement integrated coastal geological survey vessel. It fills a critical gap in China''s capabilities in this field and significantly enhances the nation''s coastal geological survey capacity. The vessel''s drilling system is equipped with multiple coring tools tailored to different stratigraphic layers， and emergency safety protocols have been established specifically for coastal drilling operations. The system successfully completed a 140m deep drilling task in the western waters of the North Yellow Sea， achieving a core recovery rate of 92.7%. Field applications have demonstrated that the drilling system of the Marine Geology No. 17 Vessel can effectively fulfill coastal geological survey drilling and coring missions.
