Founder-led Energy & Infrastructure Advisory · UK · Middle East · Africa
Oclas is an energy and infrastructure advisory practice. We work with operators, developers, investors and public bodies to close the gap between what an asset is expected to deliver and how it actually performs. Senior attention, specialist expertise and advice grounded in operational reality.
The results shown on this site come from work Sheyi N. Lisk-Carew delivered personally over more than twenty years in energy and infrastructure. They are his career track record, not work contracted by Oclas.
A fixed-scope diagnostic of why an asset or business is not delivering what the plan assumed. Process, data, decision rights and governance, mapped against the value they are costing you. Delivered in four to six weeks with a costed improvement roadmap.
Fixed fee · defined scope
Retained senior counsel through operational change: target operating model, maintenance strategy, management of change, root cause analysis and the KPIs that make improvement stick. Including turnaround and shutdown readiness, where stakeholder alignment decides the outcome before the plant comes down.
Monthly retainer
For investors pricing an asset or a portfolio: an operator's read on whether the business case survives contact with how the asset is actually run. Maintenance backlog, data quality, organisational capability and the realistic cost of closing the gap.

Selected Principal Track Record. Career experience delivered personally by Sheyi N. Lisk-Carew over more than twenty years across energy, utilities and infrastructure.
Oil & Gas · Collaborative Working · Africa, Kazakhstan, Netherlands
Process Implementation Lead, Shell Collaborative Working Environment programme. Led the process implementation team across multiple international assets, with an estimated annual benefit of more than US$75m in production efficiency. Well restart times fell from around six days to under three, field travel reduced by 15%, and the programme contributed to an estimated 3% net production increase against prior decline.
Oil & Gas · Digital & Remote Operations · International
Business Process Workstream Lead. Led a remote-operations study for a major offshore gas facility, mapping manual interventions and designing the operating model and maintenance strategy for minimal-personnel operations. Around 80% of maintenance hours were corrective; the roadmap shifted that towards predictive and preventive.
Refining & Petrochemicals · Operational Excellence · UK
Business Process Workstream Lead. Led a transformation workstream covering management of change, root cause analysis, KPIs and loss capture, helping turn recurring operational losses into permanently addressed issues. Later supported a major shutdown and turnaround, including stakeholder and decision-rights work before the plant came down.
Water & Wastewater · Asset Management · UK
People and Process Programme Manager, client-side. Aligned operational and maintenance processes across three regions ahead of a new enterprise work and asset management system, and specified and managed the external delivery team.
Power · Government · Nigeria
Lead Strategist, Presidential Task Force on Power. Worked across seven workstreams and developed the national investor portal for Nigeria's Presidential Task Force on Power.
Oclas is a founder-led energy and infrastructure advisory practice serving clients across the United Kingdom, the Middle East and Africa. We focus on the gap between strategy and day-to-day delivery: how work is organised, how assets are maintained, how decisions are made and whether the data is good enough to support them.
Our approach is shaped by more than twenty years of experience built personally by Sheyi N. Lisk-Carew across operators, utilities, consultancies and public-sector programmes. That experience is the foundation of the practice, but the historic engagements and results remain Sheyi's personal career track record.
We keep the model senior-led. The Principal stays closely involved, and trusted senior delivery partners are brought in where the scope needs additional specialist capability. As Oclas grows, the same standards of evidence, accountability and practical delivery apply.
Most improvement programmes start with what the system says. We start with what people actually do.
Our approach is consistent whether the asset is an offshore platform, a refinery or a water network. We map the process as it is documented, then validate it alongside the people doing the work. We identify where the documented process and the real one differ, quantify what those gaps cost, and separate what can be fixed now from what genuinely needs system change.
It is simple, practical work. The value is often sitting in the gap between the documented process and what happens in practice.
