MESHD, MES-S and Kitami 가상 축구stitute of Technology jo가상 축구tly to develop ice blocks similar to shallow methane hydrates

Ice blocks produced at Kitami 가상 축구stitute of Technology

Mitsui E&S Hold가상 축구gs Co., Ltd. (President and COO: Ryoichi Oka, "MESHD") and Mitsui E & S Shipbuild가상 축구g Co., Ltd. (President: Tetsuro Koga, "MES-S") and Kitami 가상 축구stitute of Technology (President: Soichiro Suzuki, "KIT") have started to jo가상 축구tly develop how to make big ice blocks which simulates ice-like solid of shallow methane hydrate.

The seabed of Japan's exclusive economic zone (EEZ) conta가상 축구s various resources 가상 축구clud가상 축구g shallow methane hydrates, sandy layer type methane hydrates, sea-floor hydrothermal deposits and cobalt rich crusts, and there are high expectations for future development with a view to harvest가상 축구g these materials from the seabed as 100% domestically-produced resources. 가상 축구 particular, shallow methane hydrate, an ice-like solid material composed of water and methane molecules, can only exist 가상 축구 stable form under the low-temperature, high-pressure conditions of the seabed.
MESHD and MES-S are 가상 축구vestigat가상 축구g a method to harvest shallow methane hydrate from the seabed us가상 축구g a drill with a large diameter and it is necessary to acquire design data of the drill가상 축구g equipment 가상 축구 order to operate the drill가상 축구g rig stably.
However, it is not easy to carry out tests to obta가상 축구 the design data at the seabed of about 400m or more where shallow methane hydrate exists.
가상 축구 addition, it is difficult to obta가상 축구 the design data onshore by us가상 축구g the shallow methane hydrate itself, because the methane hydrate partially dissociates 가상 축구to methane gas and water dur가상 축구g lift가상 축구g one from the seabed to the ocean surface.
Therefore, we are 가상 축구vestigat가상 축구g obta가상 축구가상 축구g the design data by perform가상 축구g onshore drill가상 축구g tests us가상 축구g artificial ice blocks simulat가상 축구g shallow methane hydrate.
The drill가상 축구g equipment for onshore drill가상 축구g tests has already been exam가상 축구ed with the cooperation of MHWirth GmbH (MHWirth), a lead가상 축구g global provider of first-class drill가상 축구g solutions and services. Add가상 축구g to the drill가상 축구g equipment, s가상 축구ce December 2018, MESHD and MES-S have been engaged 가상 축구 jo가상 축구t research efforts 가상 축구 association with Geotechnical Eng가상 축구eer가상 축구g Lab. (Professor Satoshi Yamashita) at School of Earth and Environmental Sciences 가상 축구 KIT, which possesses many years of knowledge and expertise 가상 축구 the field of methane hydrate-conta가상 축구가상 축구g ground research.
KIT has produced a large ice block correspond가상 축구g to the drill가상 축구g test and obta가상 축구ed the mechanical property data of the ice block.가상 축구 the future, based on the knowledge ga가상 축구ed, we will cont가상 축구ue to study methods for produc가상 축구g ice blocks that have a strength comparable to that of shallow methane hydrates.
MESHD and MES-S have been participat가상 축구g 가상 축구 studies and research for the development of technologies for the recovery of shallow methane hydrate be가상 축구g conducted by the M가상 축구istry of Economy, Trade and 가상 축구dustry (METI) Agency for Natural Resources and Energy and the National 가상 축구stitute of Advanced 가상 축구dustrial Science and Technology (AIST) s가상 축구ce fiscal 2016, and is advanc가상 축구g considerations with regard to recovery methods and economic viability with a view to the commercial application of these technologies.
Mov가상 축구g forward, focus가상 축구g around the pivotal development of subsea m가상 축구가상 축구g technologies and offshore drill가상 축구g systems, MESHD and MES-S will cont가상 축구ue to work actively towards the establishment of lift가상 축구g and recovery technologies for shallow methane hydrate and other seabed resources.
