EU project develops air bag ship rescue system to prevent
sinking
In recent years we have seen a
number of tragic disasters where ships lose their stability and flips upside
down. The Costa Concordia disaster in January 2012 saw the
loss of 32 lives after deviating from its planned route and contacting the sea
floor. More recently in April 2014 we saw the sinking of the MV Sewol in South Korea with 293
deaths, mostly secondary school children. And it’s not just human lives at
stake as oil spillages can be devastating to the environment. Now, there may be
hope for future prevention with the SuSy project – Surfacing System for Ship
Recovery.

The SuSy project is an EU-funded
investigation into methods of keeping merchant ships upright on the surface in
times of buoy damage or other stability destroying issues. They have looked
into an airbag system that would deploy airbags during times of distress that
would help keep the vessel afloat and what’s more, they have turned the idea
into a proof of concept.
In order for such a system to be
effective, it needs to be large enough to support the ship in times of danger
and also must be able to be deployed rapidly, such that the ship does not
topple to a point of no return. The proof of concept was demonstrated in
2013 on a model bottom of a medium-sized tanker in the port of Chalkida,
in Greece. “Our challenge was to produce enormous amounts of gas from
small cartridges which is quickly released into inflatables,” describes
project partner Reinhard Ahlers, managing director of Balance in
Germany.
The methodology of the project was a
combination of two technologies. The first is the rescue system used in
submarines that uses liquid or solid fuel to blow water out of the ballast
tanks in a very short time to provide additional buoyancy. The second is the
use of air pressure systems with inflatable Kevlar reinforced balloons.
The project looked into and proved
two setups, the first having the balloons sandwiched between two hulls and the
second having external balloons, however one expert voiced concern at the
project’s double hull approach. “Given the location of balloons in the
double hull, not only will the construction of the ship be much more
difficult and costly. But inspection and maintenance will be almost impossible
– hence these systems will be unreliable,” says Egbert Ypma,
researcher at the Maritime Research Institute Netherlands in
Wageningen, in the Netherlands.
The balloons hold potassium
nitrate (used in gunpowder), an epoxy resin and ferric oxide commonly
known as rust. The gunpowder oxidises the epoxy resin which produces a gas that
consequently inflates the balloons; the rust acts as a catalyst. As the blast
is so rapid a lot of heat is generated and to prevent any damage to the
balloons, either ambient air can be mixed into the balloon using a secondary
cannister or a heat exchanger can be used just before the gases enter the
balloon.
The project says that although a
proof of concept has been made the project is still far from seeing fruition
and there is a lot of work to go to optimise the inflation and location of the
balloons. But with such disasters as mentioned before, we eagerly await an
additional level of marine safety
