M/V HYUNDAI FORTUNE
The M/V HYUNDAI FORTUNE is the latest container ship to suffer a cargo explosion and/or fire at sea. Initial reports of this incident that occurred on March 21, 2006 in the Gulf of Aden from Hyundai Merchant Marine allege the initial cause was fireworks. There were reportedly 7 containers of fireworks stowed aft of the accommodation, but the IMDG code prescribes these should be stowed above decks; however this picture of a large hole on the port side and above the water line indicates something exploded below decks.

My review of the information that I've been able to obtain so far indicates it is highly unlikely the initial explosion involved the fireworks aboard the Hyundai Fortune. Modern fireworks formulas are very stable and only a series of packing, handling or other mistakes could possibly lead to their ignition onboard a ship.

The most likely scenario given the hole in the port side above the water line near the engine compartment is a fire and explosion below decks, which then ignited the cargo - including the fireworks - above decks.

The idea the fireworks might
have functioned because of tropical heat is also unlikely. All Class 1 goods
must pass a thermal stability test as part of the classification process. UN
Series 4 (a) requires no functioning or significant degradation of the product
when placed in an oven at 75º C for 48 hours.

I also question stowing DG above the engine compartment and
in proximity to the accommodation. The aft portion of a ship with all of the
machinery and human activity is the most likely place for fires to start, and
thus the last place DG should be stowed.

Hyundai Marine has placed a worldwide moratorium on all fireworks shipments. Containers of fireworks are piling up in China at the peak of the shipping season for the summer festivals in Europe and North America. Other carriers' schedules and capacity limit options - especially for 1.3G fireworks - so this may have a negative impact not only on the fireworks trade, but the many events that rely on fireworks to attract patrons.
