Remotely Operated Seafloor Drill with Extended Coring Depth Capability

9403812威廉姆森这项建议寻求第二阶段拨款，以完成在第一阶段启动的遥控深海岩心取样工具的可行性评估。该设计采用经过验证的陆地钻探工具和技术，以获取50至100米深至4000米的坚硬岩石和沉积海底的岩芯。拟议的演习可以在机会船上部署，使用目前大多数联索政治处船只上提供的传统甲板装卸设备。第二阶段的工作将建造、测试和实地试验。该原型装置将被用来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海底取心工具的商业化(第三阶段)和全面实施，该工具能够获得以前只能通过钻井船获得的样品。拟议中的钻探将为研究界和近海工业提供具有成本效益的海底采样技术。

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.
