HH Angus redesigned the pump house and storage tank farm providing automotive fluids to the vehicles in the truck assembly plant.

Our project scope covered replacing ten 50,000 litre and three 25,000 litre storage tanks. The system also required seven new truck offload pumps and twelve new plant delivery pumps. Because it was not an option to shut down the plant to facilitate the work, co-ordination and timing between the construction activities and plant operations was critical to the success of the project.

A steam-heated glycol loop heating system was provided for the storage tanks containing high viscosity fluids. Glycol was pumped through a closed loop system and controlled via temperature control valves in each tank.

Due to the flammable and combustible fluids stored at this facility, a four zone Aqueous Film Forming Foam (AFFF) fire protection system was used. The total calculated flow was greater than 3,000 USGPM. The fire protection system was interlocked electrically to the process function, and connected directly to both the in-house and municipal fire brigade to assure maximum protection and safety.
