A technique for sub-sea intervention operations involves the use of a compliant guide that extends between a surface location and a sub-sea installation. A dynamic seal is locked into place to provide a sub-sea dynamic seal that can be used to facilitate the intervention operations. The dynamic seal may include two dynamic seal members. The two dynamic seal members each have their own hydraulic activation systems or they use the same hydraulic activation system. No specific details of the seals are evident.
