At 06h30, 20 minutes into the refueling operation, fire broke out at the fuel line hatch, likely caused by the abrupt disconnection of the jet fuel line due to rough seas and unexpected movement of both ships. The jet fuel line was slightly shorter than the two HFO lines, while also being thinner and located between the two larger HFO lines, which might have caused sailors to rely on the sagging of the more visible HFO lines under the reel-in catenary to estimate the remaining reel capacity of the fueling apparatus. The jet fuel line was forcibly pulled off before the HFO lines had no sag left, resulting in fuel being spread into the fuel lines hatch and all around the fuel pumping compartment at the rear of the isle. The resulting fire rapidly spread out of control, engulfing the aft section of deck 10 in mere minutes, and damaging the electrical instrumentation of the fuel hatch, preventing FSS Mora Tefai from decoupling the fuel lines, aggravating the fire as heat soon lit the heavier HFO fuel. |

''Perei Rokui'' ordered evacuation of the ship after 4 hours of unsuccessful efforts, due to concerns of explosion of the ship's ammo reserves and weapons, but remained on board with a team of volunteers in an ultimate effort to save the ship. Onboard fire suppression systems remained active due to Rokui's decision of maintaining engine power as long as possible. Despite not being equipped with the correct chemicals to fight hydrocarbon fires, the fire suppression systems proved being decisive in cooling the ship structure and preventing the fire from openly spreading across large open spaces like the rear dock and hangar. After 20 hours of fighting, the makeshift team of volunteers and international assistance had managed to put off the last fires without suffering losses. 67 crewmen suffered from light injuries or incommodation due to the dense toxic smokes, 12 of them requiring hospitalization. |

The Niuhiti class is a class of aircraft and helicopter carriers in service in the Feguan Navy. The official designation of the class is LHD Niuhiti (Landing Helicopter Dock), with indicatives ranging from CH-N01 to CH-N04 for the 4 sisterships in service in the Feguan Navy.
History
Origins
The Niuhiti class is the result of a 3-years designing process by VAA Naval Industries in response to the 2041 Blue Act of Defense, a governmental budget law aiming the renewal and expansion of the Feguan Navy.
In 2039, VAA Naval Industries studied and sketched the concept of a multi-purpose light aircraft carrier, code-named XVH-4. The proposed vessel would be conventionally powered, fitted with a rear dock for landing ships and barges (originally the LCT-07 and LCB-09). A wide deck would cover the top, with a command isle located to the starboard side, alike existing aircraft carriers. This deck would allow the deployment of helicopters, VTOL and STOL aircrafts, sub-orbital spacecrafts (such as the Draco- series) and conventional fighters with a short taking-off requirement. Most of Fegeland's indigenous fighters would be able to take off.
When the Blue Act of Defense was approved in 2041, VAA Naval Industries proposed the XVH-4 draft, which was approved. Four initial units were ordered for a total of 4 million FF (Feguan Franc).
Construction began at Ranga Bay Harbor drydocks 4 and 6 (2 units), Fegua (one unit), and Vaimarata (delegated to Huturoan Shipyards for one last unit), with the first unit being completed by 2044 without delays.
Launch & initial career
The first unit, CH-N01, was christened at Ranga Bay on June 2044. The name "FSS Nuihiti" was chosen after the Feguanesian east wind niuhiti. The other 3 ships were christened soon after, after other major Feguanesian winds : FSS Pafa'ite (CH-N02), FSS Toherau (CH-N03), and FSS Maoa'e (CH-N04).
Fire at sea of FSS Maoa'e
FSS Maoa'e (CH-N04) was severely damaged by a fire while at sea during offshore refueling operations near the Kolus Strait in November [YEAR]. The ship was coupled with the AOR FSS Mora Tefai tanker for refueling at the time of the incident. At 06h30, 20 minutes into the refueling operation, fire broke out at the fuel line hatch, likely caused by the abrupt disconnection of the jet fuel line due to rough seas and unexpected movement of both ships. The jet fuel line was slightly shorter than the two HFO lines, while also being thinner and located between the two larger HFO lines, which might have caused sailors to rely on the sagging of the more visible HFO lines under the reel-in catenary to estimate the remaining reel capacity of the fueling apparatus. The jet fuel line was forcibly pulled off before the HFO lines had no sag left, resulting in fuel being spread into the fuel lines hatch and all around the fuel pumping compartment at the rear of the isle. The resulting fire rapidly spread out of control, engulfing the aft section of deck 10 in mere minutes, and damaging the electrical instrumentation of the fuel hatch, preventing FSS Mora Tefai from decoupling the fuel lines, aggravating the fire as heat soon lit the heavier HFO fuel.
Firefighting efforts rapidly proved to be insufficient and the ship issued a mayday call, receiving assistance from the nearby FSS Shikaze and FSS Waimafatu frigates. Other nearby ships from the SFRK, Orion Navy and Gallante Federation also provided assistance, both in rescue and firefighting operations. Capt. Perei Rokui ordered evacuation of the ship after 4 hours of unsuccessful efforts, due to concerns of explosion of the ship's ammo reserves and weapons, but remained on board with a team of volunteers in an ultimate effort to save the ship. Onboard fire suppression systems remained active due to Rokui's decision of maintaining engine power as long as possible. Despite not being equipped with the correct chemicals to fight hydrocarbon fires, the fire suppression systems proved being decisive in cooling the ship structure and preventing the fire from openly spreading across large open spaces like the rear dock and hangar. After 20 hours of fighting, the makeshift team of volunteers and international assistance had managed to put off the last fires without suffering losses. 67 crewmen suffered from light injuries or incommodation due to the dense toxic smokes, 12 of them requiring hospitalization.
The FSS Maoa'e suffered severe damage from the fire, several decks being destroyed, including part of the island, hangar and many of the facilities located on the rear half of the ship. The forward half of the ship, the flight deck, rear dock, most of the hangar and both engine rooms were spared. The ship was discretely towed back to Ranga Bay six days after the incident and spent three years in a drydock of the Ranga Bay Shipyards for internal investigations and early repair works, before being moved to a remote area of the shipyards.
The incident was broadly publicized, and the opacity of the Feguan Navy sparkled political debate, the left wing of both Chambers pleading for decommission of the ship and reforms in the Navy. Public opinion was further influenced by revelations made by several whistleblowers on social media of lax safety standards in the Navy. Capt. Rokui's efforts to save the ship were however acclaimed as "heroic" by the public, and he later received the Feguan Distinguished Service Order (DSOF) in recognition for his efforts.
