For marine passenger vessels, regardless of a company’s size, an SMS ensures that each crewmember is given standard and clear procedures for routine and emergency operations. An SMS specifies crewmember duties and responsibilities, as well as delineates supervisory and subordinate chains of command, so that each crewmember understands what to do during critical vessel operations and emergency scenarios. Developing an SMS includes creating plans for crewmember responses to a range of possible emergency situations. SMSs also include procedures for performing and tracking preventive maintenance, as well as for crew training, emergency preparedness, documentation and oversight, and other actions that prioritize safe operations.
Further, we have recommended that the USCG require that companies operating domestic passenger vessels develop and implement a preventive maintenance program for all systems affecting the safe operation of their vessels, including the hull and the mechanical and electrical
systems.[9] We generally expect recommended actions to be completed in 5 years, but this has
languished for 20 years and, therefore, is in an unacceptable status. This is our oldest open marine safety recommendation. We have kept it open because the USCG has informed us since 2012 that it would include this action as a component of a broader requirement for SMS.
We continue to believe that an SMS is an essential tool for enhancing safety on board all
US passenger vessels, and that the USCG is the appropriate authority to require such systems. We
fully support the requirement mandated by Congress. We also believe that an SMS is not a
substitute for important safety regulations that are issued by the USCG. Safety regulations need to
be implemented and an SMS enhances the impact of those regulations.
Fire Safety for Small Passenger Vessels
As a result of the
Conception disaster, we issued seven new safety recommendations
specifically related to fire safety and egress. All seven were addressed by the Elijah E. Cummings
Coast Guard Authorization Act of 2020 and are currently classified “Open—Acceptable
Response.”
To ensure fire safety aboard small passenger vessels, redundancy is critical. First, we
made several recommendations to the USCG to update its regulations regarding accommodation
spaces in all passenger vessels, including those constructed prior to 1996. We recommended that
they require all accommodation spaces, for new vessels and those currently in service, have
smoke detectors".[10] Second, we recommended that the USCG develop and implement an
inspection procedure to ensure that operators are conducting “roving patrols” as required by
regulations and which has been codified in US law since 1871. [11] The current statute states that
“the owner, operator, or charterer of a vessel carrying passengers during the nighttime shall keep
a suitable number of watchmen in the vicinity of cabins or staterooms and on each deck to guard
against and give alarm in case of fire or other danger.”[12] This was not the practice on
Conception, other vessels owned by Truth Aquatics, nor, according to interviews, other dive
boats in Southern California.
Even if a fire breaks out, loss of life is still preventable with adequate options for and
awareness of emergency egress. The
Conception had two means of escape from the bunkroom:
spiral stairs forward and an escape hatch aft, accessible from either port or starboard aisles by
climbing into one of the top aftermost inboard bunks. However, both paths led to the salon, which
was filled with heavy smoke and fire, and the salon compartment was the only escape path to
exterior (weather) decks. Therefore, because there was fire in the salon, the passengers and one
crewmember housed below were trapped and were not able to escape. If regulations had required
the escape hatch to exit to a space other than the salon, optimally directly to the weather deck, the
passengers and crewmember in the bunkroom would have likely been able to escape. For those
reasons, we recommended that the USCG update its regulations for small passenger vessels with
overnight accommodations, including those constructed prior to 1996, to require a secondarymeans of escape into a different space so a single fire will not affect both escape paths and to ensure there are no obstructions to egress.[13] These recommendations are currently classified “Open—Acceptable Response,” because we understand that the Coast Guard has initiated a rulemaking project to implement the recommendations for all small passenger vessels with overnight accommodations, including vessels constructed prior to 1996.
In addition to fire safety in vessels with accommodation spaces, prior to the
Conception
tragedy, we issued two recommendations to the USCG regarding unmanned spaces. We
recommended that they require fire-detection systems in unoccupied spaces with machinery or
other potential heat sources on board small passenger vessels, and for them to issue a marine safety information bulletin regarding the need to use only approved material and components in fuel tank level-indicator systems.[14] The USCG has issued the bulletin and the recommendation has been closed successfully, but further action is needed to require additional fire detectors.
Again, we appreciate Congress addressing these safety issues in legislation, and for the
cooperation and partnership of the USCG. We look forward to the USCG issuing a final rule to
implement our recommendations and improve safety.[15] Until that time, the recommendations will
remain open. In the meantime, operators of vessels with overnight accommodations can act now
to improve the safety of their passengers and crew. They can start with the following even before
the USCG completes rulemaking:
- Install smoke detectors in sleeping quarters and ensure they are interconnected so when one detector goes off, they
all do. The
Conception crewmember who discovered the fire could not hear the fire alarm from the crew berthing on the upper deck.
- Ensure that the primary and secondary emergency escape paths do not lead to the same space, which can be blocked by a single hazard. The
Conception had two means of escape from the lower deck bunkroom, but both led into the salon, which was filled with heavy smoke and fire. Tragically, the salon compartment was the only escape path to the weather deck. Because there was fire in the salon, the passengers were trapped.
- Keep the escape routes unobstructed at all times.
- Remind crewmembers to perform roving patrols and why they are so important. Our investigation found that the
Conception fire was uncontrollable by the time it was discovered because the crewmember, who ultimately died, was asleep in the bunkroom.
Amphibious Passenger Vessel Safety: The Importance of Action
Unfortunately, we know that the consequences of failing to address the lessons learned
from our safety investigations can be further tragedies. Almost 20 years after the sinking of an
amphibious passenger vessel that killed 13 people in Arkansas, we investigated the sinking of a
DUKW amphibious passenger vessel,
Stretch Duck 7, on Table Rock Lake near Branson,
Missouri.[16] We discovered that long-known safety issues caused the sinking and resulted in the loss of 17 lives. I want to thank you for addressing these safety issues in H.R. 6865, the Coast Guard Authorization Act of 2022.
DUKW amphibious vehicles were designed and built in the 1940s for military use during World War II; some were later converted for commercial service.[17] They are unique vessels with special challenges that must be addressed to ensure passenger safety.
Five minutes into its voyage on July 19, 2018, the
Stretch Duck 7, with 31 passengers aboard, encountered a severe storm known as a derecho. While trying to reach land, 7 minutes into the voyage, the vessel took on water and sank approximately 250 feet away from the exit ramp. Passengers were caught by the vessel’s canopy as it sank. Only a few of the surviving passengers stated that they were able to float free without encountering any obstructions. Several hours prior to the accident, the National Weather Service had issued a severe thunderstorm watch for the area, followed by a severe thunderstorm warning a minute before the vessel departed.
NTSB investigators found that the accident vessel was originally constructed with a low freeboard, an open hull, and no subdivision or flotation, resulting in a design without adequate reserve buoyancy. We determined the probable cause of the sinking was the operator’s continued operation of waterborne tours after a severe thunderstorm warning was issued for Table Rock Lake, exposing the vessel to a derecho, which resulted in waves flooding through a non-weathertight air intake hatch on the bow. Contributing to the sinking was the USCG’s failure to require sufficient reserve buoyancy in amphibious passenger vessels. Contributing to the loss of life was the Coast Guard’s ineffective action to address emergency egress on amphibious passenger vessels with fixed canopies, such as the
Stretch Duck 7, which impeded passenger escape.
As noted, these safety issues were not new when the
Stretch Duck 7 sank. They were identified after the 1999 sinking of the
Miss Majestic, another DUKW amphibious passenger vessel, on Lake Hamilton, near Hot Springs, Arkansas.[18] As a result of that sinking, 13 passengers died. Survivors of the
Miss Majestic accident confirmed that the vehicle sank less than a minute after the deck edge at the stern was submerged, leaving insufficient opportunity for passengers to escape. Vessel maintenance, reserve buoyancy, and survivability—specifically, impediments to passenger egress caused by the vessel’s canopy—were among the major safety issues identified by our investigation of the
Miss Majestic accident.
As a result of the
Miss Majestic sinking, we recommended that the USCG require greater stability and reserve buoyancy in amphibious passenger vessels.[19] Further, until the goals of that recommendation were achieved, we urged the USCG to require—among other measures—that canopies be removed from waterborne vessels, or that such vessels have installed a USCG-approved canopy that does not restrict horizontal or vertical escape by passengers in the event ofsinking.[20] These recommendations were closed unacceptably in 2003 and 2007, respectively.
Regrettably, had these recommendations been implemented, a future tragedy could have been
avoided.
More than 15 years later, because of the
Stretch Duck 7, we recommended again that
amphibious passenger vessels have sufficient reserve buoyancy so they remain upright and afloat
in the event of damage or flooding, and that for DUKW vessels without sufficient reserve
buoyancy, that they require the removal of canopies, side curtains, and their associated framing
during waterborne operations to improve emergency egress in the event of sinking.[21] The USCG
has not been able to identify a feasible solution to achieve the necessary level of reserve buoyancy, and contracted with the National Academy of Sciences (NAS) to conduct an independent review of potential modifications. The USCG has also issued a marine safety information bulletin recommending removal of canopies as an initial step.[22] For these reasons, both recommendations remain classified “Open—Acceptable Response.”
In 2015, we investigated a highway crash of a DUKW in Seattle, Washington. [23] As a
result, we recommended the USCG amend its Navigation and Vessel Inspection Circular (NVIC)
1-01, a guidance document that relies on voluntary compliance, to ensure passengers unbuckle
before waterborne operations and the crew confirms that passengers have complied.[24] Following
the
Stretch Duck 7 sinking, we recommended reviewing and revising the NVIC.[25] Although the
USCG has communicated to us it will make the recommended revisions, the NVIC has not been
updated; therefore, these recommendations remain classified “Open—Acceptable Response.”
Lastly, the benefits of these safety improvements are not realized if crews have insufficient
awareness. Accordingly, we have recommended that the USCG review and revise training,
especially as it relates to severe weather.[26] Each of these recommendations is on our 2021–2022
Most Wanted List. Again, thank you for addressing these issues in the pending Coast Guard
authorization.
Conclusion
The loss of 34 lives on the
Conception, less than 100 feet from shore, shook this community
and the country. It reminds us that the potential for catastrophe is always present, including on
small passenger vessels, and we must do what we can to prevent needless deaths and mitigate
injuries. Passenger vessels should have SMSs and provide adequate fire detection and
extinguishing systems and enhanced emergency egress options. Inaction can lead to further
tragedy, as we saw with the
Stretch Duck 7 almost 20 years after the
Miss Majestic sinking. We recognize the progress that has been made, yet, there remains room for improvement. The NTSB stands ready to work with you and this Committee to continue improving passenger vessel safety.
Thank you again for the opportunity to testify today. I am happy to answer your questions.
[1] There are currently 93 open safety recommendations to the USCG, 32 of them with the status “Open—Unacceptable Response.” Of the 93 recommendations, 24 are associated with our Most Wanted List of Transportation Safety Improvements item, “Improve Passenger and Fishing Vessel Safety,” and 8 of those are currently classified “Open—Unacceptable Response.” These recommendations are included in the appendix to this testimony.
