What are the duties of a production manager in offshore platforms?

Production Manager — Offshore Platform

Senior offshore operations leader accountable for safe, compliant, and optimized hydrocarbon production from topsides process facilities and wells, coordinating people, plant, and permits to meet the daily target and protect asset integrity.

I. Core Responsibilities (Day-to-Day)

I.1 Production delivery and optimization — Balance well inflow, separation, dehydration/degasification, compression, power, water/gas injection, exports; manage chokes and network constraints to meet the daily target with minimal deferment.
I.2 Control room oversight — Direct DCS/SCADA operations, alarm management, setpoint governance, and overrides; ensure safe operating envelopes and adherence to operating procedures.
I.3 Loss management — Lead daily loss/deferment reviews, bad-actor analysis, and corrective actions; maintain loss register and production efficiency KPIs.
I.4 Hydrocarbon accounting — Validate metering, sampling, allocations/back-allocations; sign off daily production reports and shipment/export tickets.
I.5 Permit-to-work (PTW) leadership — Act as issuing/authorizing authority for SIMOPS, isolations/LOTO, process breaks, hot work, and confined space tasks; ensure barrier health and simultaneous operations risk control.
I.6 Process safety stewardship — Safeguard ESD/F&G/SIS impairment management, override logs, bypass minimization, and critical equipment testing; chair MoC reviews for process changes.
I.7 Chemistry and flow assurance — Set chemical dosing windows (scale, corrosion, paraffin, emulsion breakers, H2S scavengers); manage hydrate risk, pigging campaigns, and produced water quality compliance.
I.8 Maintenance coordination — Prioritize maintenance backlog with Maintenance Lead; plan isolations/returns, defects elimination, and spares criticality for production-critical systems.
I.9 Well/operations interface — Coordinate with well services, artificial lift, testing, and interventions; approve well start-up, shut-in, and ramp-up plans to protect facilities.
I.10 Start-up/shutdown/TAR execution — Lead process start-up and shutdown procedures; define turnaround scope, readiness, and commissioning performance tests.
I.11 Emergency response — Serve as Incident Commander or Section Lead during events; conduct drills, readiness checks, and post-incident learning deployment.
I.12 Compliance and reporting — Ensure regulatory/permitted limits (emissions, flaring, discharges) and produce required reports; manage audits and findings closure.
I.13 Budget and planning — Own production OPEX line items tied to chemicals, metering, sampling, and consumables; contribute to monthly forecasts and annual plans.
I.14 People leadership — Lead production supervisors, control room and field operators; competence assurance, shift handovers, toolbox talks, and performance feedback.
I.15 Interface management — Align with marine, lifting, subsea/pipeline, export terminal, aviation, and logistics to protect production schedule.
