Our subsea drills are designed on patented Wireline technology that significantly reduces the time for any drilling evolution vs. conventional drilling methods. These systems can be deployed from ships of opportunity, making them an order of magnitude cheaper than drill ships while simultaneously providing superior recovery.
Our Wireline tools and methods provide for traditional geotechnical sampling, in situ sampling at pressure and the installation of downhole instrumentation. Our systems can support any on-site investigation of the upper seafloor layers, including methane hydrates and massive sulfide minerals.
Our systems are remotely operated with real-time sensor, video and audio feedback for automation and operator control. The subsea drills shown below represent 20 years of drilling improvements and systems that are still working in the field today. We can also custom design and build systems unique to any sampling requirement.
The A-BMS (Advanced Deepsea Boring System) is a Wireline system designed and built for the Japanese Oil, Gas and Metals National Corporation (JOGMEC). The system is designed to launch through either a 7m x 7m moon pool, or over the stern through an A-Frame. The system can land on slopes up to 30 degrees in 4,000 meters of water, and then drill to 50 meters. A-BMS was provided to JOGMEC in 2011 for installation on the new Japanese Research Vessel Hakurei.
The ACS (Automatic Coring System) was delivered to the National Institute of Ocean Technology in Chennai, India in February of 2010. The ACS is designed to recover 100 meters of HQ core. The primary mission for the ACS is research in support of the Indian national initiative to investigate methane hydrate deposits within the EEZ of India, therefore the ability to recover pressurized sample is incorporated into the system.
The BMS-3 (Benthic Multicoring System) was delivered in 2008. It uses conventional rotary hard-rock and soil sampling tools combined with computer controlled automation of making and breaking down a drill string.
The BMS-2 (Benthic Multicoring System) was delivered in 2005. This system currently holds the World Record for seafloor drilling, completing a rock coring operation in a water depth of 5813 meters. View the official press release for more details on the world record.
The BMS-1 (Benthic Multicoring System) was built in 1996 by Williamson & Associates, Inc. for the Metal Mining Agency of Japan (MMAJ). This system is still in use on JOGMEC's Research Vessel Hakurei-Maru No. 2.
The 3-Meter Rock Drill was deployed in 1990. The system has recovered samples in up to 2,400 meters water depth, and the system design is for 4,000 meters water depth.
