What C&I Engineering Solutions does

C&I Engineering Solutions is an Aberdeen-headquartered engineering consultancy founded in 2013 by Grant Lunn, specialising in Electrical, Controls, Instrumentation and Automation (E,C&I) services for the energy sector. The firm delivers multi-discipline engineering across the full project lifecycle — Concept & FEED Studies, Engineering & Procurement, Construction & Commissioning Support, As-Building & Close Out, plus 24/7 Healthcare & Maintenance and Grey Market Spares & Obsolescence Management — for brownfield oil & gas, hydrogen, nuclear, and renewable energy clients.

The company's technical core is brownfield asset modernisation and legacy system sustainment. Documented capabilities include Integrated Control & Safety Systems (ICSS) upgrades covering DCS, ESD, and F&G systems; obsolescence lifecycle management for assets with forecast CoP extending to 2035; OT cyber security services aligned with OG86 and NSCS CAF; and specialist access to obsolete equipment from legacy OEMs (Honeywell TDC2000/3000, Triconex, Allen-Bradley, Siemens, GE Fanuc). Representative engagements include the ICSS upgrade of CNOOC International's Buzzard North Sea asset (800+ million BOE cumulative production), a phased NGL plant control system modernisation (Honeywell C300), and engineering support for high-pressure hydrogen electrolysers targeting industrial decarbonisation.

Revenue is generated through project-based professional services engagements under Master Service Agreements and fixed-price or time-and-materials contracts, with customers being predominantly blue-chip and international energy operators (Total E&P, BP, Enquest, Nexen/CNOOC, CNRI, Anasuria). The company is ISO 9001:2015 certified, was bootstrapped and founder-led until its October 2024 acquisition by Penspen, and now operates as a wholly owned subsidiary with the original management team intact and access to Penspen's international office network across the UK, UAE, KSA, Latin America, and the US.
