Superferry Sister Ship: Navy Finds “Agressive” Corrosion
State Legislators Beware – If you buy the Superferries, you may be getting a rust-bucket. This is the same company and virtually the same design as the “Superferry”.
The U.S. Navy has discovered “aggressive” corrosion in Austal Ltd. (ASB)’s first new combat ship designed for operating close to shore.
The corrosion is in the propulsion areas of the USS Independence, the Littoral Combat Ship built by the Mobile, Alabama-based subsidiary of Australia’s Austal and General Dynamics Corp. (GD)
“This could be a very serious setback,” said Norman Polmar, an independent naval analyst and author in Alexandria, Virginia. “If the ship develops a serious flaw, you’re not going to continue producing them.”
Permanent repair will require drydocking the ship and removing its “water jets,” a key component of the propulsion system, the Navy said in a written statement to congressional appropriations committees provided to Bloomberg News.
Aluminum-hulled ships such as Austal’s tend to rust faster than steel-hulled ships, Polmar said. “But I’m surprised it happened so early,” he said. “This ship is brand new.”
The corrosion discovery in a ship that was commissioned in January 2010 marks another blow to the Littoral Combat Ship program, planned to ultimately consist of 55 ships. In February, the Navy discovered another ship in the series, from another construction team, had a crack through the hull.
