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.

Offshore Mining

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.

Hydril Pressure Control MudLift

Our Hydril Pressure Control MudLift and SlurryLift
pump systems provide commercially viable solutions
to pump solids-laden fluid at high discharge pressures,
making them ideal for use during drilling and seabed
mining operations.
