SHIP EQUIPMENT<br />
Tapping in to a new way<br />
to make onboard savings<br />
UK firm helps ships to make significant reductions in their water use…<br />
0<br />
Water is something most<br />
of us take for granted —<br />
and it is particularly easy<br />
to see it as something of an infinite<br />
resource when you are at sea<br />
onboard your ship.<br />
However, Ecocamel — a UKbased<br />
‘water technology manufacturing<br />
company’ — is helping<br />
shipping companies to chalk up<br />
some substantial savings by making<br />
more efficient use of their<br />
shipboard H2O.<br />
One of the first vessels to demonstrate<br />
the benefits of improved<br />
water management is the UKflagged<br />
passenger ferry Norman<br />
Spirit, owned by the French firm<br />
LD Lines, which sails every day<br />
between Portsmouth and Le<br />
Havre.<br />
In September this year, following<br />
an energy audit and preliminary<br />
sample testing by Ecocamel,<br />
chief engineer officer Jim Bate<br />
decided to complete a retrofit of<br />
all 160 cabins, crew quarters and<br />
galleys by installing the company’s<br />
aerated shower heads and fitting<br />
flow regulators on all taps.<br />
The subsequent savings were<br />
dramatic. ‘The early results indicate<br />
that we are saving a staggering<br />
65% of the water we use — a<br />
saving of around 38.5 tonnes of<br />
water per day, or 14,000 tonnes a<br />
year,’ said Mr Bate.<br />
The saving in metric tonnes<br />
alone will enable LD Lines to carry<br />
an extra 40 tonne lorry on every<br />
run, which will give additional<br />
turnover of more than £200,000<br />
a year for the company.<br />
0<br />
Ecocamel designs and<br />
manufactures watersaving<br />
showerheads<br />
which use aerated technology<br />
— firstly restricting water flow to<br />
seven litres a minute, then inhaling<br />
air into the water stream to<br />
give an invigorating full flow<br />
shower experience.<br />
The old showerheads fitted on<br />
the Norman Spirit gave a flow rate<br />
of 15 litres a minute — Ecocamel<br />
uses just seven litres a minute,<br />
therefore more than halving<br />
usage immediately.<br />
After retrofitting the ship’s<br />
showers, attention turned to the<br />
taps. The flow rate of taps on Norman<br />
Spirit was very high, with<br />
many taps flowing at 27 litres a<br />
minute. Ecocamel makes flow<br />
regulators which when fitted to<br />
taps reduced the flow rate to five<br />
or seven litres a minute whilst<br />
still giving a good rinse and wash.<br />
The Ecocamel technology<br />
replaced the existing units which<br />
were installed when the ship was<br />
built in 1991. No other water-saving<br />
or energy-saving devices were<br />
installed or fitted.<br />
Stena Line has also retrofitted<br />
one of its Irish Sea ferries — Nordica<br />
— with Ecocamel showerheads.<br />
Chief engineer officer Bob<br />
Adams says: ‘In comparison with<br />
our existing showerheads, the<br />
Ecocamel produces a 32% saving<br />
on water usage, giving the Nordica<br />
a saving of up to £ 4,230 per annum<br />
Ecocamel tap aerators and flow regulators can reduce<br />
water consumption by more than 60%<br />
off the cost of water shipped on<br />
board, which is very impressive.<br />
‘Our crew say that the Ecocamel<br />
has a better flow and a better<br />
showering experience that the<br />
old units,’ he added. ‘We have retrofitted<br />
115 berths with Ecocamel<br />
hand-held showerheads.’<br />

The company says that<br />
one of the key benefits<br />
of installing its watersaving<br />
technology is that it gives a<br />
very quick return on investment.<br />
In the case of LD Lines, average<br />
savings made on water are running<br />
at 65%. The cost of the annual<br />
water bills before the Ecocamel<br />
installation was €25,000. The cost<br />
of a complete ship retrofit with<br />
water-saving technology was<br />
€3,000, leaving projected annual<br />
water costs of €7,500. The total<br />
annual savings of €17,500 generated<br />
a return on investment in<br />
just two months.<br />
In the case of Stena, the cost of<br />
installing 110 Ecocamel showerheads<br />
was £1,664.50 and projected<br />
annual savings are £4,237 — so<br />
payback and ROI will be five<br />
months.<br />
The Stena Nordica is one of the<br />
smallest ferries in the Stena fleet,<br />
and according to company management,<br />
bigger savings will be<br />
made on the vessel when tap aerators<br />
are fitted.<br />
Both ferry companies are now<br />
considering retrofitting their<br />
entire fleets.<br />

James McDonald, from<br />
Ecocamel, says: ‘Our<br />
technology is inexpensive<br />
and low-tech, yet offers massive<br />
savings on water and energy<br />
costs, tonnage and ultimately on<br />
carbon footprint.’<br />
Norman Spirit chief engineer<br />
Jim Bate adds: ‘Over the past three<br />
years the Norman Spirit has used<br />
on average around 55 tonnes of<br />
water per day, at a cost of €25,000<br />
a year. Retrofitting all of our cabins<br />
and facilities with Ecocamel<br />
products has cut our annual water<br />
costs to around €7,500 — and to<br />
achieve this we spent £2,700.<br />
‘Furthermore, we expect that<br />
we will also show significant savings<br />
on our fuel and energy costs,’<br />
he adds. ‘LD Lines has a strong<br />
environmental policy and we are<br />
absolutely delighted that our<br />
work with Ecocamel will have a<br />
huge positive impact to reduce<br />
our carbon footprint and help the<br />
environment.’<br />

energy-saving audit to ferry and<br />

Many seafarers we note are under the illusion that to qualify for the 100%<br />
foreign earnings deduction, all they have to do is spend 183 days out of<br />
the country on foreign going voyages.<br />
Many have found to their cost, when investigated by the Revenue that it is<br />
not that straightforward and of course it is then too late to rectify.<br />
