Southampton docks may build generator for ships to cut carbon emissions

Power generator plan for docks to reduce emissions Power generator plan for docks to reduce emissions

CRUISE liners docking in Southampton could be plugged into an onshore power supply to stop harmful emissions being blown into the city.

Port bosses ABP and cruise giants Carnival UK yesterday said they were considering introducing the low-carbon technology, known as cold ironing, in Southampton.

It would make the port one of the greenest in the country and comes after a report last year warned that chemicals within smoke from liners, tankers and cargo ships could travel into the lungs of those onshore.

The scheme is outlined in the draft Port of Southampton Masterplan 2009, which sets out ABP’s vision for the docks for the next two decades.

It’s most likely the costly technology would only be retrofitted in the short-term at the city’s cruise terminals as many modern liners are already at the cutting edge of sustainable technology.

If implemented, liners would be made to switch off their generators while berthed.

Shore-side generators would then power the vessel’s refrigeration, cooling, heating, lighting and emergency equipment as it loads or unloads.

As an added incentive, the electricity could come from the city’s Energy Centre, which has supplied more than half of the port’s power for the past six months.

ABP commercial manager Ian Palacio said the only way cold ironing could succeed would be if the major cruise liners partnered with the port to make it happen.

“We don’t want to force anyone into it, but we always want to be ready for that opportunity,”

Mr Palacio said.

The Daily Echo understands high-level discussions have been held between ABP and Carnival UK about the viability of cold ironing.

In a statement, a Carnival UK spokesman said: “Carnival UK as an environmentally aware company would be willing to work with any port in developing projects which were both commercially viable and environmentally friendly.”

Southampton City Council highlighted the potential for shore-side electricity in its Air Quality Action Plan.

The report found shipping contributes up to a quarter of nitrogen dioxide in the Town Quay area and 17 per cent in Commercial Road.

Ports in the United States, Canada and Germany have already invested millions in the technology to help improve air quality in coastal cities.

Scientists from the University of California last year estimated as many as 60,000 deaths a year worldwide were caused by emissions from ships running on cheap fuel called bunker oil.

There are no restrictions on the types of fuel vessels consume in UK ports, however the International Maritime Organisation is considering introducing new requirements to use cleaner, more expensive fuels. But they’ve been held up by disagreement between developed and developing countries about who should participate.

Shore side power supplies have difficulties with connections, voltages & frequencies. Once these are sorted out with the ships that dock, then routine maintenance can be carried out (some of it has to be done with the engine shutdown). Thus the ship owners are all for this happening. I was quite surprised to find that commercial vessels spend on average 100 days a year in dock.

only problem is when you restart engines in the first few minutes, they can cause just has much pollution has a engine running on tick over all day, what would be better if ships fitted scubber units to the stack, but it be good for the noise pollution,
lines tend to only stay for a short time.

Cold ironing is a shipping industry term that first came into use when all ships had coal fired iron clad engines. When a ship would tie up at port there was no need to continue to feed the fire and the iron engines would literally cool down eventually going completely cold, hence the term "cold ironing".

Wow - informed comment on maritime issues.

Care to tell us the story of HMS Golden Rivet?

This sounds like a good initiative. I like Southy's point about cold engine start up but I would guess the overall benefit of switching off is still very high. - I would guess that the initial black plume from a cold diesel engine is largely heavy hydrocarbon particles which will tend to fall to earth over time rather than stay in the atmosphere. I did some research years ago into engine emissions for a "New Forest Diesel piston and ring manufacturer" - the black exhaust looks polluting but it's the invisible nitrous oxides and monoxides that are the real killers.

sulphur is the cancerous one andy, what makes up most off that black smoke is semi burnt fuel, the very dark stuff is just soot from the sides off the stack, this will fall back to the ground depending on the weather, like damp weather it more than likely to drop on the decks of the ship, but very dry hot weather it will travel few 100's of miles.
when you start an engine up from cold it uses more fuel to keep it going till it reaches is working temp, has with ships only staying for a very short period will it be worth it, the only benefit i can see, it will be quieter.

What I don't understand is how this can be an environmental benefit when, like most of the rest of us, the port sources its electricity from the highly inefficient National Grid system. Surely most of the fancy cruise ships have high tech generators onboard producing both heat and electrical power not lumping great coal fired power units that were built in the 70's that guff most of the energy they produce out into the atmosphere in the form of heat!?

Thanks Southy. When I was doing the research (many years ago now!)I was given access to the technical library of Ricardo Consulting engineers down at Shoreham and Wellworthy's test cells at Ampress - a fantastic combination of diesel engine expertise which I was lucky to have. We assumed low sulphur diesel in our modelling due to improving refining techniques plus legal restrictions on pollutants after refining (including sulphur) As I said, nitrous oxides were the most dangerous post combustion product - worse in petrol than diesel too. Anyway, if you compute the fuel burnt in even one hour of running compared to the additional fuel consumed during a cold start then turning the engine off is a good thing. The real problem as you will know, is that machines like to keep running, and repeated cold starts will shorten the life of the machinery and ultimately of the ship. That is the real issue.
