The pressure hull of a submarine has many penetrations to allow for the ingress and egress of sea water, fuel, lube oil and air. For the Collins Class submarines, specifically designed steel hull forgings are installed in the hull to provide reinforcement for these penetrations. This paper presents a case study of corrosion and repair of the hull forgings. The original nickel plated design of the hull forgings suffered corrosion due to sea water attack and subsequent dissimilar metal coupling. The corrosion resulted in metal loss which introduced a risk of serious impact on the function of the forgings. Short-term repair of the forgings was implemented by way of localized weld repair and selective brush plating of nickel. Simultaneously, investigations into long term solutions were carried out.

A flamesprayed thermoplastic coating was applied in 2000 to the sheet piles of the Delta Pier, located at Naval Submarine Base at Bangor, Washington. That coating system quickly failed. This paper discusses several rehabilitation strategies, the construction restraints, and how these divergent factors were resolved.
