Seafloor Drilling and Sampling Systems

Williamson & Associates has been developing seafloor drilling and sampling systems since 1991. Our remotely operated systems feature flexible deployment platforms that can be mobilized on a wide range of vessel profiles.

 
 

Remotely Operated Core Sampler

Our latest drill system, the Remotely Operated Core Sampler (ROCS), is designed to be mounted on a work class ROV, making this tool one of the most flexible and economic ways of obtaining deep sea core samples.

Please contact us for further specifications.
