This wasn’t
some old small junk built by some dodgy shipyard and run by some third rate
outfit. The MOL Comfort was a five year old, 90,000 tonne boxship built by one
of the best known Japanese shipyards and operated by one of the best known Japanese
companies. Her breaking up into two big pieces at sea, less than a thousand
miles from Mumbai, should be a big mystery. Or perhaps not.
I am
disregarding the rumours going around that the Comfort was carrying arms in
4000 odd containers meant for Syrian rebels; even if true, this is not material
to her breakup. I am also disregarding, for lack of any evidence whatsoever, one
or two oddballs who are saying that the Russians torpedoed the ship.
In the
absence of the other usual suspects- weather, collision or grounding, I am
willing to wager that unknown stresses caused by under declared container
weights over the Comfort’s short working life – which is a routine occurrence
in the trade that everybody knows about and winks at- has much to do with her snapping
into two.
Decades
after the realisation that under declared container weights can have disastrous
consequences on the stability or integrity of ships- causing them either to
fracture or capsize or both- the IMO has been finally ‘seized of the matter’ (as the bureaucrats say in India).
There may well be, in another few
years, amendments in the pipeline to SOLAS that call of verification of
container weights. Not that that by itself will solve the problem; IMO
regulations rarely do.
Those of us
who have sailed on container ships- feeders or larger- know the life
threatening consequences of false container weights well. I hope the trumped up
Operations Manager in a very well-known shipmanagement company is reading the
Comfort story and remembering his veiled threats to me when I shut out two
dozen containers in a port because we were fully loaded long before we thought
we would be, thanks to the unknown under declared manifested weights of the
boxes. I hope that alleged ‘logistics specialist’ in another top rung shipmanagement
setup is reading the story too- he was spouting half-baked stability theories
to push me to load beyond my margin for safety, until I politely reminded him
that the number of years of my experience at sea coincided approximately with the
number of his years of experience on mother earth.
(Pardon me
for not naming people, companies or ports involved. Just following the old
shipping tradition of not embarrassing the guilty.)
Experienced
Master’s and Chief Officers on container vessels get used to keeping a hawk’s
eye on the GM, the stability curve and the shearing forces of their ship. All
are critical. A low-ish calculated GM can capsize you if enough containers that
happen to be loaded high have their weights under declared. (So can, on feeder vessels with low displacement, picking up
two 40 tonne containers on two ship’s cranes simultaneously at the discharge
port.) Too many container ships have simply rolled over in port, either
alongside or when they are pulled off by tugs after loading; I had the
misfortune- and an invaluable learning experience- of seeing this happen to
another ship in port.
However,
although one can try to keep the calculated shearing forces and bending moments
low (with a margin of safety for misdeclaration) during each stage of each
cargo operation, this is often far tougher to do in practice, and is often given
lower priority. Because usually nothing dramatic happens.
Maybe, with
the MOL Comfort, it did. The only way we will know is if each of the containers
aboard is salvaged and weighed. And even that will not tell us much about the
cumulative effects of loading and discharging containers- many undoubtedly with
weights substantially under declared- over the preceding five years. Maybe
forensic or other tests on the steel can tell us more.
No doubt
the IMO will accelerate the formation of its committees and sub-committees
after the Comfort. Closer to the action, the CYA operation will undoubtedly
accelerate too, with classification societies, owners, operators, shippers and
insurers obfuscating facts to ‘protect their interests.’
Maybe
some of the better operators will try to push shippers and their organisations
to do something immediate to address the issue, although I don’t know how far
they will succeed in the present market conditions. Scores of emails must be
already flying to and fro between all the container ships on earth and their
managers who sometimes appear as if they are on another planet.
I hope that
prudent Masters and Chief Officers tighten up even more after the Comfort,
re-examining their loadicators and calculations for probable errors and
reassessing their earlier comfort levels of minimum GM levels, maximum stresses and such. And, tongue in cheek, maybe the industry will
realise that the under declaration of container weights can cost more than
(yawn) crew’s lives. It can also cost (gasp) big
money.
Yeah,
regardless of the real reason why the MOL Comfort broke up- underdeclared box
weights or not- maybe some good will come out of all this.

Having read about this problem, what you're saying makes total sense. What the investigation will finally reveal could be masked by lot of commercial interests.
"Declaration of Weights" will soon follow, with added responsibility for ship staff to somehow verify that the declaration is true. Just like the meaningless Decln of Security !!
