Questions about LNG

Sir,

Some questions regarding Liquefied Natural Gas (Delayed Glen Sannox ferry may have two year wait for LNG fuel – Banner May 13).


For information LNG is natural gas converted to liquid at a temperature of -162℃ which reduces its volume by a factor of 600, making it easier to transport.

Firstly, what is the real green footprint, cradle to grave, given the gas is extracted, liquefied, shipped 8,000 miles from Qatar to Kent and then 460 miles by road to Ardrossan, all the while at  -162℃ ? Did anyone do the sums to check the environmental benefits outweigh the environmental costs?

I’m not an engineer, but I’ve been advised the ship’s engines run on diesel all of the time. Once under steady cruising conditions, 90 per cent of the diesel can be replaced by gas which produces 30 per cent less carbon dioxide than diesel. I understand the system is designed for LNG tankers on ocean voyages, not the 55-minute Ardrossan to Arran service, where the LNG can only be used at best midstream. So how many minutes of environmental gain (at 30 per cent of diesel equivalent) are we getting against the environmental costs?

What impact has the dual fuel design had on the cost and complexity of the build, and the (ahem) timescales?


Who insisted on dual fuel and why? Did anyone consider battery powered ferries, like those being deployed in Norway?

Given the LNG combustion risks, how far are the proposed LNG storage bunkers from the new Ardrossan ferry terminal? What is a safe distance?

To summarise, as we jokingly used to say in my industry: who sold you that then?

Yours,

Douglas Templeton,
Whiting Bay.

 

Less-abled access

Sir,

Regarding the letter from Duncan Dowie, in last week’s Arran Banner, about disabled access and less-abled access on Arran, Arran Estates gave permission to upgrade their land for the less-abled to walk longer distances.

When the road up Glen Rosa was levelled, I put a wooden bridge over the burn of the low hill. The bridges are still there and perform when needed. The bridges were not approved by those who know better.

One other path that has been repaired is the one from the Sannox Burn to the North Sannox Burn. There was a lot of hardening done. The path at the Newton Shore, to the hillock of the rock, received a compliment from a man who said that the new path meant that he could now walk along the shore.

The sad part of my less-abled path work is the refusal of able-bodied people objecting to the work done in the villages of Catacol, Sannox, Brodick, Lamlash, Whiting Bay, Kildonan, Blackwaterfoot and a path for the bottom of Imacher Brae.

These were the places I had planned to give the less-abled people a chance to enjoy our land in all seasons. There are lots of people in Arran who have done, and are still working on, helping those who are less-abled.

Yours,

Alastair Hendry,

Brodick.
