Fabrication & EPC

Dorman Long operates out of three (3) yards in Lagos. Our historical head office at Idi-Oro, our galvanizing plant at Agege and our waterfront facility at the Nigerian Naval Dockyard (NND), Victoria Island. All these are fully equipped fabrication yards with the capacity to deliver world class fabrication service.
