Abstract
A protective cap assembly uses a heavy corrosion inhibitor fluid in the primary chamber (the central bore of the mandrel or hub) and a lightweight corrosion inhibitor fluid in the zones outside of the mandrel or hub. The protective cap assembly uses a two port hot stab receptacle and connects the first port to the primary chamber and the second port to the secondary inlet port with a secondary inlet check valve. The primary chamber is vented directly to the subsea environment. With the secondary inlet check valve added to the secondary inlet port, the second port of the protective cap assembly is connected directly to the secondary inlet check valve.
