Responsibilities of an offshore safety engineer in drilling projects?

Offshore Safety Engineer — Drilling Projects

Ensures process and personal safety on offshore drilling assets by leading risk management, control of work, emergency readiness, and regulatory compliance across all well construction phases.

I. Core Responsibilities

I.1 Plan and govern HSE: develop campaign HSE Plan, risk register, ALARP demonstrations, and Safety-Critical Elements (SCE) performance standards for the drilling scope.
I.2 Hazard identification and analysis: facilitate HAZID/HAZOP, Bow-Tie analyses, LOPA for high-risk tasks, SIMOPS risk matrices, and barrier verification plans.
I.3 Control of Work: administer ePTW, verify isolations/LOTO, authorize hot/cold work, confined space entry, and oversee gas testing requirements.
I.4 Drilling safety assurance: verify well control barriers, witness BOP function/pressure tests, review kill plans, confirm ESD/F&G cause-and-effect testing, and track barrier impairments.
I.5 Mechanical handling/DROPS: lead dropped-object (DROPS) inspections, review lifting plans and pre-lift risk assessments, and verify lifting gear certification and color coding.
I.6 Emergency preparedness: maintain the Emergency Response Plan; plan and run drills (well control, fire, H2S, abandon ship, man overboard, medevac); assure EER (escape, evacuation, rescue) readiness.
I.7 Incident management: lead/coach root cause investigations (ICAM/TapRooT), classify actual/potential severity (including HiPo), and drive corrective/preventive action closeout.
I.8 Occupational health: manage exposure controls for H2S, noise, vibration, heat/cold stress, ergonomics; coordinate respiratory protection and fit-testing.
I.9 Environmental controls: oversee spill prevention/response, waste management, bunkering safety, and compliance with discharge and emissions limits.
I.10 Contractor HSE interface: ensure HSE Bridging Document is implemented across operator, drilling contractor, and service companies; verify competencies and safety-critical training currency.
I.11 Assurance and audits: execute rig readiness and SEMS/HSE-MS audits, MOC reviews, SIMOPS readiness reviews; track HSE actions to closure.
I.12 Data, KPIs, and reporting: maintain HSE dashboards (TRIF, LTIF, barrier KPIs), issue weekly/monthly HSE reports, and communicate lessons learned offshore and onshore.
I.13 Coaching and culture: drive stop-work authority, deliver toolbox talk quality checks, and mentor supervisors on risk visualization and decision making under uncertainty.
