The final bulkhead design met all criteria. Due the requirement that the bulkhead had to be tipped up into position, MRD had to implement a design with sufficient clearance around the bulkhead while still sealing against rough concrete and into sharp, inconsistent internal corners. MRD constructed a template for the diving contractors to carry into position to take specific dimensions for guaranteed fit.
MRD provided rigorous PE stamped design drawings and feasibility studies to ensure bulkhead performance. MRD, Inc. also provided custom-designed anchor restraint channels to hold the bulkhead in place. Adjustable buoyancy tubes and internal air chambers allowed the customer to easily move the bulkhead into position.
MRD provided specialized internal plumbing circuits so that customer could undertake the additional step of proving a seal boundary existed between the mechanical and inflatable seals. A load centering plate was provided between the anchor channels and the bulkhead to distribute the load in the event of single restraint channel failures.
