Which development? Fires during repair work are nothing new, and seem to be common in US as well:
Back in 2012, America lost a far more valuable asset, the multi-billion dollar attack submarine USS Miami (SSN 755), because a shipyard worker, eager to leave work early, set the sub on fire.
...
Avoidable shipyard accidents are sidelining far too many modern American ships.
Outside of the USS Miami, 11 U.S. sailors were injured last month in a fire on the USS Iwo Jima (LHD 7), a critical Marine-toting mini-carrier. USS Oscar Austin (DDG 79) also suffered a fire in November 2018, and repairs will keep the ship out of the fleet for almost two years. According to USNI News, the USS Fitzgerald (DDG 62) suffered a shipyard fire as well, and the ship’s Captain noted more than fifteen other fire safety incidents in the yard, including “poorly staffed fire watches, a smoldering deck, combustible material catching on fire, the discovery of previously unreported burnt-cable spot fires and fires that melted equipment.” In 2011, a fire torched the stacks of the USS Spruance (DDG 111). Other recent shipyard mishaps have included over thirty million dollars of damage to the future destroyer Delbert D. Black (DDG 119) after a collision in April 2019.
Sad, but fact of life, and when it happens appropriate commissions generally take note and rectify things (at least temporarily).
