Subsea Mining

HMH provides a broad portfolio of field-proven, state-of-the-art technologies for the exploration and exploitation of resources from the seabed.

We have more than 30 years’ experience in offshore diamond mining using an airlift drilling system. Additionally, we are involved in the extraction of methane hydrate from the seabed. With an in-depth understanding of equipment availability, cost optimization and our broad portfolio of offshore solutions, we can define the most efficient method for continuous harvesting of subsea solids and minerals. We are currently developing solutions for deep sea mining together with partners.
