Electrical & Instrumentation Engineering Services
Complete E&I design and documentation — single line diagrams, cable schedules, instrument index, loop drawings, I/O lists, cable tray and earthing layouts, and control, PLC, ESD and fire & gas system engineering support.
SLETEC provides electrical and instrumentation (E&I) engineering services for oil & gas, petrochemical and industrial projects. Our E&I engineers deliver the full package of electrical design and instrumentation deliverables required for construction and commissioning — coordinated with the piping, mechanical and structural disciplines within the same engineering team.
On the electrical side we prepare single line diagrams, electrical load lists, power distribution design, cable schedules and cable sizing, cable tray layouts, earthing and lightning protection layouts, and lighting layouts. On the instrumentation side we produce instrument index and datasheets, instrument loop drawings, I/O lists, junction box schedules, hook-up drawings and cause-and-effect matrices.
SLETEC also supports control system, PLC panel, automation, ESD and fire & gas system engineering. All E&I deliverables are prepared in line with client specifications and referenced to IEC, IEEE, NFPA, API RP 500/505, ISA and applicable Saudi Aramco standards where required — delivered under NDA and integrated with your project document control.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.
