SGC provided electrical engineering and CADD services for production of fabrication drawing for a skid-based evaporative distiller to be installed at a petrochemical facility in Yemen. All of the skid-mounted instruments, controls and motors required interfacing with a remote Distributed Control System (DCS) provided by the owner. This interface was accomplished by means of two junction boxes – one for control signals and one for instrumentation signals.
This project required all electrical components to be rated for use in a Class I Division 2 environment per owner-supplied specifications. SGC specified and designed all electrical equipment in compliance with the hazardous location requirements. Additionally, all 120V motors required local motor starters which were powered via a skid-based 120V distribution system including a 460V/120V transformer, a circuit breaker distribution block, and 120V local motor starters including a Hands-Off-Auto selector switch and indicating lights.
Our engineering deliverables included an electrical bill of materials, motor and load list, control and instrument interface junction box wiring and layout diagrams, and electrical cable installation details.
