A recent news article published in the Loadstar states that misdeclared Li-Ion battery shipments a rising threat to shipping.
Lithium-ion (Li-Ion) batteries issue
The increasing prevalence of lithium-ion (Li-Ion) batteries being carried on containerships amid rising misdeclarations is a major concern for marine insurers, experts say.
According to a recent Allianz Global Corporate & Specialty (AGCS) report, misdeclared cargo has been implicated in a number of near-miss incidents recently, with false declarations including labelling them as ‘computer parts’.
In one case, the US Coast Guard reported a fire produced temperatures “hot enough to create a hole through the metal container’s structure”.
Battery fires are complex enough that land-based fire crews are having to introduce new, and sometimes experimental, measures to fight them.
Unlike normal fires, they can be starved of oxygen and continue to burn, and trying to fight battery fires with water is often unsuccessful or even makes things worse, because lithium reacts with water to form lithium hydroxide and flammable hydrogen gas.
Coding down the individual cells
The best way to extinguish them is by cooling down the individual cells.
But experts say ships’ onboard firefighting capabilities, especially on large vessels, are insufficient to tackle even ordinary fires, in many cases.
“There are more fires emerging from misdeclared cargoes of batteries confirmed as the source,” a representative of marine insurers told The Loadstar. “So it is not speculation to say the problem is increasing.
“There is probably no limit to the size of ships, so long as the factors to manage risk are proportionately secure. But they are not. Firefighting systems are limited in terms of reaching high up. The number of crew on board is limited – lean manning has become the accepted model of ship operations.”
The implications are bad for car-carriers as well, with increasing numbers of electric cars being transported. It is has not been determined whether the presence of Li-Ion battery-powered cars was the cause of the fire on Felicity Ace, but authorities are agreed that it was almost certainly an exacerbating factor.
