I write further to the successful completion of contracts at the above mentioned sites. Works involved the dismantling of structures (compliant with CDM regulations) and site clearance. I am pleased to provide a letter of reference to Merkland Tank for future use in tendering for similar projects.
Both contracts were completed within contractual obligations in a timely and professional fashion. The full time site supervision provided by Merkland Tank was knowledgeable, competent and ameniable. Site operatives were highly skilled and cooperative.
Merkland Tank responded promptly to requests from Shanks and submitted payment requests without delay.
"I would not hesitate in working with Merkland Tank again,or in recommending them to others."
This is to certify that we have used Merkland Tank for all our cold storage tank cleaning and chlorinating
at Glasgow Airport along with pipe insulating work.
Work was carried out to BS6700 and all other relevant Health and Safety Regulations pertaining to this type of contract.
We have worked with Merkland Tank for a number of years and always find them to be most helpful and conscientious with the work and would have no hesitation in recommending them for this type of work.

PETERHEAD POWER STATION
Scottish Hydro PLC
Peterhead Power Station is home to three of the tallest oil tanks in the UK. These 70m diameter tanks are used as standby should a problem occur with the main power generating facility.
Merkland Tank was awarded the contract for cleaning of the tanks based on itís excellent safety and environmental record and itís ability to provide a comprehensive service.
The project involved the transfer of residual oil from the tank, gas clearance of the tank
, followed by removal of oil sludge and the squeegee cleaning of the remaining solid residues.
The tank was then hot water jetted using 3000 psi hot jetting units. The remaining oil/contaminated water was then removed using the vacuum tanker
and disposed of at an approved facility.
"The contract was awarded to you after evaluating competitive tenders,taking into account your policy towards safety and the environment. The work was carried out efficiently and to budget."

KINGS LINES OIL FUEL DEPOT
Balfour Beatty, MOD Gibraltar
Used for refuelling of naval warships, Kings Lines Oil Fuel Depot is one of the largest underground fuel tank cells in the world.
Merkland Tank was awarded the contract for cleaning of the tanks based on itís experience, itís outstanding safety record and flexible working practices.
Located 200m inside the Rock Of Gibraltar and extending to a depth of 600m, this contract represented a major challenge for Merkland Tankís management and workforce.
Occupying eight employees over a period of four months, the contract involved considerable risk. Employees would be working in a very dark enclosed space, cleaning and removing oil residues from this massive tank.
To undertake the task safely and efficiently, Merkland Tank had to construct a mobile staging platform above a trough which would catch the oily residues dislodged from the interior. These were then dissolved in diesel and pumped to the surface for disposal at the sullage tanks. Venturi ventilation fans were used to minimise workersí exposure to fumes.
The contract was completed on time to the complete satisfaction of the client.
ďOur recommendation of your company has been more than justified by your excellent performance in completing the cleaning of two very large cells, to the required standard within a tight scheduleĒ
Works Services Manager
The contract was awarded to Merkland Tank based on a competitive tender, the production of an excellent Safety Method statement and a solid work history.
The project involved the emptying of the tank and disposal of the residual oil, the gas freeing of the tank
, followed by the removal of the internal and external linings.
Once this was successfully completed, the tank was then cut into sections using oxygen/propane torches for removal from the island.
The contract was completed over two weeks with minimal disruption to the distillerís normal operations.

Demolition of 3 Oil tanks and associated pipelines
Construction of a new power station wasbegun in 1970, for South of Scotland Electricity Board (SSEB), laterScottish Power, at Wemyss Bay on the River Clyde. The station wasdesigned to use Heavy Fuel Oil (HFO) but the oil crisis of the early1970's ensured that it was not economically viable to run, and whilethe station was only utilised in part during the miners' strike of1984/85, it was never fully commissioned and was maintained asstrategic reserve until decommissioning in 2009. The decision wasthen taken to demolish the station.
As a prelude to demolition of thestation, Merkland Tank was contracted to remove the oil contained inthree Fuel Oil storage tanks, then clean the tanks and associatedpipework.
The cleaning project commenced inJanuary 2010, during one of the worst winters on record.
Working with Demolition Contractor KDC,all pipelines had first to be cleared and removed prior to cleaningthe storage tanks. Pipelines were systematically cleaned and removedfrom site, including transfer pipes at the jetty. This work requiredoperatives to work above water in all weather conditions with no oilspillage or risking injury.
Work on tank cleaning began when allpipelines had been successfully removed. Despite the station beingout of service for many years, nearly 2,000 tonnes of cold HFO had tobe removed. Using a number of high capacity pumps and DISAB tankerunits, the HFO was decanted and distributed to various disposal sitesaround the UK. When the oil had been completely removed the tankscould be cleaned.
The arduous task of physically cleaningthe storage tanks (76m diameter) was made more difficult due to thelack of a site water supply to use with jetting equipment.
By September 2010 the project was completed on time and within budget with no lost time injuries or incidents.
