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 many year’s experience, it is our 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 Tankâ€™s 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 workersâ€™ exposure to fumes.
The contract was completed on time to the complete satisfaction of the client.
Our 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 schedule“

PETERHEAD POWER STATION
Scottish Hydro PLC
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 it’s excellent safety and environmental record and it’s 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.”
Scottish Power plc
Location : Inverkip Power Station, Clyde Estuary
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 was designed 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.
