This disclosure describes an apparatus and a system for inspection of deepwater assets, e.g., pipes and pipelines that traverse the ocean floor. In one embodiment, the apparatus includes a housing that retains a compensation fluid therein to form a fluidic environment. A digital detector resides in the fluidic environment. The digital detector can generate digital images in response to radiation that penetrate though the deepwater asset and impinges on components of the digital detector. In one embodiment, the digital detector utilizes one or more seal members to secure the components together. The seal members may be permeable and/or impermeable to the compensation fluid thereby preventing and/or permitting migration of the compensation fluid between certain components of the digital detector.
