Rising seas threaten Norfolk Naval Shipyard, raising fears of 'catastrophic damage'
“Every year you wait to make decisions and take actions, the risk goes up," said retired Rear Adm. Jonathan White.
"...But the shipyard now faces its greatest existential threat: R
ising Seas and extreme weather driven by Climate Change.
In the past 10 years, Norfolk Naval Shipyard has suffered nine major floods that have damaged equipment used to repair ships, and the flooding is worsening, according to the Navy. In 2016, rain from Hurricane Matthew left
2 feet of water in one building, requiring nearly $1.2 million in repairs...
And that wasn’t even a direct hit — the most immediate worry, former military leaders say, is a strong storm that blows right through the area.
“It would have the potential for serious, if not catastrophic damage, and it would certainly put the shipyard out of business for some amount of time,” said Ray Mabus, who was the Navy secretary under President Barack Obama. “That has implications not just for the shipyard, but for us, for the Navy.”
Among the shipyard’s greatest vulnerabilities are its five dry docks, which are waterside basins that can be sealed and pumped dry to expose a ship’s hull for repairs. Once inside, vessels are often cut open, leaving expensive mechanical systems vulnerable to damage from storms and flooding.
The dry docks “were not designed to accommodate the threats” of rising seas and stronger storms, according to a 2017 report by the Government Accountability Office. Navy officials warned the government watchdog agency that flooding in a dry dock could cause “catastrophic damage to the ships.”
