P&IDs produced right first time. HAZOP actions closed out. Flare systems sized correctly. Equipment datasheets that pass vendor review. This is what 20 years of process engineering discipline delivers - across BP, TotalEnergies, Shell, ADNOC, Saudi Aramco, ExxonMobil and Mobil assets.
P&ID deficiencies found at HAZOP are a change order. Found at commissioning, they are a delay measured in months. Found during operation, they are a regulatory incident. The quality of your front-end process engineering defines your project cost floor.
P&IDs that don't reflect the operating philosophy, miss isolation points, or carry unincorporated HAZOP actions cascade errors directly into piping, instrumentation, and ESD logic. Every discipline downstream works from your P&IDs - their quality is your project's quality.
Rework at detailed design: $500K - $5MA flare network that can't handle the blocked-outlet case or a knockout drum sized without accounting for two-phase slugs is a fundamental design error. Discovered at HAZOP it is reworked. Discovered at commissioning it is a project crisis requiring emergency re-engineering and schedule impact.
Late redesign: $1M - $8M + scheduleA separator designed for nominal conditions but not the max water cut late-life case, or a pump sized without NPSHA verification for the minimum suction pressure scenario, becomes an underperforming asset from day one. Equipment sizing done once from a validated simulation model is correct forever.
Equipment replacement: $200K - $3MHAZOP actions that are assigned but never formally closed out, incorporated into P&IDs without verification, or tracked in a spreadsheet nobody owns represent live regulatory liability. An IOC audit that exposes open HAZOP actions against operating facilities is a production suspension risk.
Regulatory exposure: production suspensionA heat and mass balance that covers only the design throughput case but omits turndown, start-up, and maximum water cut scenarios produces a process model that doesn't represent the real operating envelope. Downstream disciplines then design to wrong conditions - creating systemic errors across the project.
Re-simulation + IDC rework: $300K - $2MManual or automatic depressurisation calculations that underestimate inventory or Mach number limits, or PSVs sized without accounting for fire case and blocked outlet simultaneously, create plant that cannot safely manage emergency conditions. This is an area where simulation shortcuts have direct safety consequences.
Incident consequence: irreversibleEvery capability below has been exercised on live IOC projects - not described from a brochure. We produce and issue these deliverables to construction standard under the operator's own quality system.

Process engineering deliverables produced personally on assets across four operating environments - from unmanned wellhead platforms to major onshore gas plants.
Topsides process engineering is the most deliverable-intensive discipline on any platform project. Every P&ID, every equipment datasheet, every C&E chart has a downstream consequence. We have produced complete process deliverable suites for CSP wellhead platforms, manned accommodation platforms, and ultra-sour gas processing facilities.
Subsea process engineering demands absolute rigour in P&ID development and operating guideline documentation - because the consequences of an error in a subsea chemical injection schematic or an SSIV logic sequence are discovered at significant cost and delay. We have produced AFC P&IDs and operating guidelines for Shah Deniz 2 - among the world's most scrutinised subsea systems.
Offshore FPSO and fixed platform process engineering requires the H&M balance to cover the full production life - not just plateau. Separator sizing, compression configuration, and utility system design all need to work at maximum water cut, minimum GOR, and every start-up scenario. We model all of these cases and produce the deliverables to match.
Onshore gas plants, gathering networks, and trunkline systems require process engineering that integrates pipeline hydraulics with facility design - particularly where depressurisation safety, relief system sizing, and long-distance multiphase hydraulics all need to be resolved correctly at FEED to avoid costly re-engineering at construction.
Every scope is executed by our Lead Process Engineer - not delegated to a junior team. You get 20 years of experience applied directly to your project, with a trackable, auditable deliverable record behind it.
