The challenge

Cleaning the interior and exterior of the 107 tank at CEPSA's facilities in San Roque, recovering the maximum amount of crude oil possible without putting any of Dominion’s employees at risk.

DOMINION's +

Manual cleaning of the tank could put Dominion's cleaning team at risk. Accordingly, the proposition was made to CEPSA for the project to be performed in three different stages, led by a technical team with extensive experience in each aspect involved. As a result, and using state-of-the-art technology, the process time took half as long and was performed with no safety risks.

Results

The client recovered a total of 1,300 cubic metres of crude oil and a total of 200 cubic metres of solid material was separated. This saved the client from having to resort to landfill management for most of the initial volume, therefore reducing the effect on the environment.

Cepsa San Roque

The maintenance work on tank 107 at the CEPSA facilities in San Roque were awarded to Dominion in October 2019. The project consists in the interior and exterior cleaning of the tank to recover as much crude oil as possible so it could be put into service as quickly as possible. 

The tank has a diameter or 62 metres with a total of 1,500 cubic metres of crude oil. Removing the sludge manually could put the cleaning team at risk. Accordingly, the proposition was made to CEPSA for the project to be performed in three different stages, led by a technical team with extensive experience in each aspect involved. 

Firstly, the BLABO automated tank cleaning system was used to collect the sludge from the interior. At the same time, the product being recovered was treated in the sludge centrifuge unit to recover as much of the product as possible. Finally, Dominion's specialist high-pressure water cleaning team performed the final stage of the project which consisted of hydroblasting. 

This project showed how Dominion has sufficient capacity, flexibility and adaptability to offer the best solution to suit each of its clients. Without cleaning personnel having to work in complicated conditions and being exposed to safety risks, a total of 1,300 cubic meters of crude oil was recovered without having to access the tank at first. Our client also set the tank back into operation in 3 months. The delivery time for the alternative had been estimated to take twice as long.
