<p>A method of applying acid-wash to a subsea connection assembly, in particular a stabplate connection, in order to remove unwanted material such as marine growth and calcareous deposits. The method consists of inserting a plug (22), containing channels (23), into a central opening (21) in a stabplate connection and injecting acid-wash through the plug (22). The plug (22) may be carried by an operating tool arm of a remotely operated underwater vehicle (ROV) (24).</p> |
