According to the testimony, a deluge system valve that protected the area where the fire broke out was made inaccessible because of the fire. Additionally, a deck hatch failed, allowing the fire to spread to adjacent areas.
The investigation has prompted the Coast Guard to call for an investigation into Grandeur of the Seas' sister ships, according to the testimony. Grandeur of the Seas is part of Royal Caribbean's Vision Class, along with Enchantment of the Seas, Legend of the Seas, Rhapsody of the Seas, Splendour of the Seas and Vision of the Seas.
A fire onboard Grandeur of the Seas broke out on the aft of the ship May 27. The ship sailed to Freeport, Bahamas, where passengers disembarked and were ultimately flown back to homeport Baltimore. It returned to service July 12.
