Human Reliability
The Human Reliability Leader
How leaders convert field intelligence into disciplined action before weak signals become operational surprises in high-hazard operations.
Owner-Side Industrial Advisory
Industrial recovery, restart and asset performance under pressure
For gas, LNG, refining, petrochemicals, power and other asset-intensive operators facing disruption, brownfield complexity, integrity risk, or stalled execution.
I help leadership teams restore clarity, prioritize what matters first, and move performance forward through disciplined owner-side support.
Recover control. Improve asset performance. Masterplan the future.

Selected situations I help with
Restart after incident, outage or disruption
Brownfield recovery with integrity uncertainty
Reliability, maintenance or CMMS performance that is not translating into fewer surprises
Aging assets, obsolete systems, spare-parts exposure or unclear renewal priorities
Executive teams needing decision-grade priorities and disciplined follow-through
Why Jenzer Advisory
Why Jenzer Advisory
Built for high-pressure operating realities
Built from real asset accountability
Experience across Iraq gas delivery, Gulf refining, reliability improvement, operations readiness, and major industrial programs.
Calm structure under pressure
A disciplined owner-side approach that helps leadership teams focus decisions, expose risk, align priorities, and close critical actions with evidence.
From intervention to stronger capability
The result is not just short-term support, but stronger local ownership, better routines, and more durable performance after the immediate pressure eases.
Owner-side advisory
Why owner-side advisory matters
Most consultants advise. Most contractors execute. Jenzer Advisory helps owners make better decisions, govern risk, align stakeholders and drive disciplined execution when asset condition, integrity risk, performance pressure and capital choices collide.
Decision clarity
Convert fragmented information into decision-ready priorities.
Owner accountability
Align leadership, technical functions and frontline teams around one operating view.
Execution discipline
Track owners, evidence, blockers and closure until the work moves.
Who this is for
For leaders who need faster clarity, stronger prioritization, and disciplined execution in complex industrial environments.
NOCs, JVs, and other asset-intensive operators facing brownfield complexity
Gas, LNG, refining, petrochemicals, power, and critical industrial infrastructure
Leaders managing damaged, disrupted, high-risk, or underperforming assets

The Human Reliability Leader
No Surprises in High-Hazard Operations
A practical executive briefing on how leaders convert field intelligence into disciplined action before weak signals become operational surprises.
Insights
Selected insights for recovery and brownfield leaders
Practical perspectives on integrity uncertainty, restart discipline, and execution under pressure.
Recovery & Restart
What damaged gas and LNG assets need in the first 10 days
When disruption hits, activity rises fast but clarity often lags behind. The first 10 days are about recovering control, not just assessing damage.
Recovery Governance
Why energy recovery fails after disruption
Most recovery efforts lose momentum not because teams are inactive, but because integrity uncertainty, blurred governance, and restart pressure collide at the same time.
Brownfield Operations
Five brownfield recovery lessons from Iraq that Gulf operators can use now
Brownfield recovery is difficult not because people lack effort, but because complexity exposes weaknesses in sequencing, interfaces, and decision discipline.
Owner-Side Quality
Decision-ready clarity built for action
Single source of truth. Clear decision asks. Evidence-based closure. The information leadership teams need to decide and move.
Typically issued within 24 hours after each forum.
"Within six weeks, our steering committee finally had the clarity to make decisions that had been stuck for months. The operating rhythm now runs itself."
GM, Major Capital Program

1
Rapid diagnostic
A focused review to understand the asset situation, surface the real constraints, and identify where leadership attention is most needed first.
2
Targeted sprint
A short, practical intervention to align priorities, frame decisions, define owners, and establish momentum.
3
Embedded support
Continued owner-side support to strengthen routines, build local capability, and help the improvements hold after the initial push.
Proof
Representative prior experience
Selected anonymised examples from prior operating, transformation and owner-side delivery roles. Client and asset names are omitted where appropriate.
Asset Performance | Reliability, maintenance and turnaround discipline at scale
Gulf refinery transformation
Supported a major refinery transformation across two operating sites, focused on reliability, maintenance discipline, turnaround performance, leadership cadence and local capability building.
- 75% reduction in production losses
- 50% reduction in incidents
- Operational availability lifted to top-quartile levels
- Performance sustained beyond the initial intervention
- One site later recognised as world-leading in its peer group
Why it matters
This experience underpins the No Surprises Asset Performance model: start with facts, follow the value, solve live reliability problems, and build the client-owned operating system that prevents recurrence.
Recover | Owner-side readiness and execution under high uncertainty
Iraq gas brownfield delivery
Represented asset-owner interests in a high-risk gas development environment involving brownfield and greenfield interfaces, operations readiness, digital completions, local workforce transition and high-pressure project delivery.
- Owner-side readiness across a multi-billion-dollar development portfolio
- Safer, more disciplined completions and start-up preparation
- 50% improvement in safety and production efficiency through digital completions
- Stronger local delivery capability and reduced dependence on expatriate teams
- Better alignment between project execution, operations readiness and asset interests
Why it matters
This experience underpins the Recover pillar: restore clarity, protect asset interests, govern readiness, and keep execution moving when complexity, risk and uncertainty collide.
Masterplan | Lifecycle, cost and risk decisions for mature assets
European mature-asset value programme
Led cross-functional value and lifecycle work across mature industrial assets, combining zero-based budgeting, operational optimisation, proactive facility risk management and end-of-life asset decision support.
- USD 300 million OPEX reduction
- Economic life of an end-of-life asset extended by five years
- Proactive facility risk management piloted and later adopted more broadly
- Stronger link between risk, cost, lifecycle exposure and asset decisions
Why it matters
This experience underpins the Masterplan pillar: make lifecycle risk visible, connect technical and economic choices, and convert asset concerns into decision-ready renewal roadmaps.
Client names and detailed references available where permitted.
