Island Lady fire partly caused by use of wrong materials, US Coast Guard report reveals

On January 14, 2018, Island Lady, a US Coast Guard-inspected vessel operating as a shuttle to transport passengers to and from an offshore casino vessel in Florida’s Pithlachascotee River suffered a devastating fire not long after getting underway from the dock.

Within minutes of observing that one of the vessel’s engines was overheating and a significant amount of smoke was emanating from the vessel, the master altered course and quickly grounded the vessel in shallow water. Passengers were then able to evacuate the vessel and wade ashore.

Several people were injured and there was one resultant fatality.

The fire was intense, fast moving, and ultimately burned the vessel to the waterline.

Investigators determined a number of causal factors that contributed to ignite and intensify the fire on Island Lady. This included a lack of company guidance regarding engine high-temperature alarms, lack of fire detection in unmanned spaces with exhaust tubing, insufficient preventive maintenance, insufficient crew training and documentation, and inappropriate material and design of the fuel tank level-indicator system.

The vessel’s fuel tank level indicating equipment consisted of clear plastic tubing connected to a stanchion that was graduated to read the tank volume in gallons.

Although this equipment did not initiate the fire, investigators determined that, once the fire spread to the fuel tank compartment, plastic materials in the level-indicating system melted and the resultant leak of diesel fuel fed and exacerbated the fire.

Island Lady was certificated and inspected as a small passenger vessel, subject to the regulations of Title 46 CFR Parts 175-185 (Subchapter T). Applicable regulations regarding the fuel tank level indicating equipment are contained in Section 182.440 (a)(7), and read: “…Tubular gauge glasses, if fitted to diesel fuel tanks, must be of heat resistant materials, adequately protected from mechanical damage, and provided at the tank connections with devices that will automatically close in the event of rupture of the gauge or gauge lines.”

In general, the CFR requirements for fuel systems, from the smallest recreational boats to the largest passenger ships, require heat resistant materials be used in the design and construction of all components.

In addition to the level indicating tubing not being constructed of heat resistant material as required, the connection of the tubing to the fuel tank was not fitted with automatic closing devices as required by 46 CFR 182.440(a)(7). Instead, a ball valve was used.

Furthermore, nearly all vessels subject to the Code of Federal Regulations are required to be fitted with main fuel supply shutoff valves at the fuel tank. These shutoff valves will stop the main fuel supply flow from the tank to the engine in the event of a fire or leak, and must be operable remotely from outside the fuel tank compartment. Fuel shutoff valve requirements for Subchapter T vessels are described in 46 CFR Section 182.455 (b)(4).

There is no compelling evidence to suggest that US-inspected vessels are not compliant with the CFR standards. However, given the volatile properties of diesel and gasoline fuels and the potential for fuel leaks to either cause or accelerate shipboard fires, the coast guard strongly recommends that vessel owners and operators verify that their vessel’s fuel systems, including tank level indicating equipment, are constructed with the appropriate heat resistant materials and automatic shutoff devices in accordance with all applicable regulations.

Investigation and inspection personnel are encouraged to maintain an acute awareness to these issues and initiate corrective actions as needed.
