ECC has performed multiple task orders at Lajes, Portugal for the US Air Force Civil Engineer Center (AFCEC) and US Army Corps of Engineers (USACE). Funded by the Defense Logistics Agency (DLA), projects include the maintenance and upgrade of the island’s fuel systems and its facilities. ECC performed inspections, repairs, and recertification of multiple aboveground storage tanks (American Petroleum Institute (API) 653), pipelines (API 570), and filter systems (API 510). Repairs included state-of-the-art technologies such as smart in-line pipeline inspections; underwater works at a fuel off-loading pier (coat blasting, recoating, and welding); and ultra-high-pressure water blasting to recoat fuel tanks. ECC also executed structural upgrades and repairs to the pier, construction of a new tank farm pump house and filter building, and large canopies over truck fuel stands. The recertified fuel tanks ranged in size from 9.87 MGal to 420 kGal, and included their smaller auxiliary tanks, floating pans, containment areas, and other safety and monitoring equipment. ECC also replaced all pressure relief valves on all base fuel systems. ECC refurbished the Military Service Station by replacing the underground storage tanks, piping, fuel dispensers, and control system; and repaired, calibrated, and serviced two fuel hydrant systems. ECC decommissioned and demolished some of the pre-existing fuel tanks and pipelines, while performing environmental assessments in close coordination with the Base and Host Nation Representatives. Work was performed in full compliance with Unified Facilities Criteria (US), Standardization Agreement (NATO), and European Union (Host Nation) regulations and requirements.
