Remotely Operated Seafloor Drill with Extended Coring Depth Capability

该提案寻求第二阶段资金，以完成第一阶段启动的远程控制深海岩心取样工具的可行性评估。该设计利用成熟的陆地钻井工具和技术，在4000米深的硬岩和沉积海底获取50至100米深的岩心。拟议的演习可以从机会船上部署，利用大多数联索特派团船上现有的传统甲板处理设备。第二阶段的工作将是建造、测试和现场试验。该原型装置将用于获取从软粘土到硬岩石基质的多个全尺寸样品。第二阶段计划的成功完成将导致商业化（第三阶段）和海底取心工具的全面实施，该工具能够获得以前只能通过钻井船获得的样本。该提案将为研究界和海上工业提供一种经济有效的海底采样技术。

9403812 WILLIAMSON This proposal seeks Phase II funding to complete the feasibility assessment for the remote control deepsea core sampling tool initiated in Phase I. The design presented utilizes proven land drilling tools and techniques to obtain cores 50 to 100m into hard rock and sedimented seafloors at locations as deep as 4000m. The proposed drill can be deployed from ships-of-opportunity utilizing conventional deck handling equipment currently available on most UNOLS vessels. The Phase II effort will construct and test and field trials. The prototype device will be used to obtain multiple, full-scale samples from soft clays to hard rock substrate. The successful completion of the Phase II program will lead to the commercialization (Phase III) and full implementation of a seafloor coring tool capable of obtaining samples previously available only through use of a drill ship. The proposal drill will provide a cost effective seafloor sampling technology to the research community and offshore industry.
