... increased with MH saturation due to particle bonding and that the bonding effect was particularly dependent on the grain size of the host sand. A high pressure and low temperature plane strain testing apparatus was also developed for visualizing the deformation of methane hydrate bearing sand due to methane...

Monitoring System for Seafloor Deformation during Methane Hydrate Production Test Tatsuya Yokoyama, Mio Shimoyama, Shinji Matsuda, Koichi Tago and Junya Takeshima OYO Corporation Saitama, Saitama, Japan ABSTRACT We have developed a monitoring system for seafloor deformation during Methane Hydrate...

... ABSTRACT: Methane Hydrate (MH) is considered to be one of the new-generation energy resources. For the development of production method to extract the methane gas from MH sediment, it is important to estimate the sediment deformation. In order to understand the geo-mechanical behavior of MH...

... of deep sea floor are the undrained shear strength and the shear stress shear displacement relation. A test stand, where shear ring, vane test, track segment tests, cone tests and plate load tests can be performed in bentonite water mixture, has been built and concepts of deformation are being developed...
