Job Title: Mechanical Testing and Commissioning Engineer

Reference no: MTC-01
Location: Offshore, Delta 

Role Objective

• Lead the mechanical completion, testing, pre-commissioning, and commissioning of upgraded crude-oil storage tanks and associated piping, valves, pumps, and utility systems, ensuring safe handover and demonstrable compliance with approved design, codes, and project specifications.

Core Roles and Responsibilities

• Lead pre-commissioning and commissioning activities for repaired/upgraded crude oil storage tanks, including mechanical completion verification against P&IDs, isometrics, and vendor data books.
• Develop and execute Mechanical Completion (MC), Pre-Commissioning, and Commissioning check-sheets in line with a Systems Completion / Completions Management database (e.g., Completions software such as SPI, Cimplicity, or equivalent).
• Supervise hydrostatic and pneumatic testing of tank shells, piping tie-ins, and associated static equipment, ensuring test packs are fully documented and signed off by all relevant disciplines.
• Coordinate flushing, blowing, and cleanliness verification of process and utility piping connected to the storage tanks prior to introduction of hydrocarbons.
• Interface directly with Instrumentation, Automation, Electrical, and Piping leads to sequence commissioning activities and resolve punch-list items (Category A/B/C) to closure.
• Witness and sign off functional testing of tank mixers, heating coils, foam systems, and any rotating/mechanical auxiliary equipment tied to the storage tanks.
• Prepare Method Statements, ITPs (Inspection & Test Plans), and Commissioning Procedures for client and third-party approval prior to execution.
• Manage the Mechanical Completion punch list and drive close-out with QA/QC and construction teams within contractual timelines.
• Participate in HAZOP, SIL/LOPA close-out actions, and MOC (Management of Change) processes relevant to mechanical scope.
• Produce daily/weekly commissioning progress reports and final Mechanical Completion Dossiers/Handover packages for client acceptance.

Qualifications and Requirements

• Bachelor's Degree in Mechanical Engineering from an accredited institution; current COREN registration is mandatory.
• B.Eng./B.Sc. (Hons) in Mechanical Engineering from a NUC/COREN-accredited or internationally ABET/Washington Accord-accredited university — Second Class Upper (2:1) or higher; no exceptions for Second Class Lower.
• Ten (10) years post-NYSC cognate experience in mechanical completions/commissioning of oil & gas storage or process facilities, of which at least six (6) years must be specifically on crude oil storage tank systems (API 650/653 tanks); general plant commissioning experience alone will not satisfy this requirement.
• A minimum of four (4) years of that experience must have been served in an OFFSHORE environment (FPSO, offshore terminal, platform, or single-point mooring facility) — onshore-only candidates need not apply.
• Registered/Certified member of COREN (Council for the Regulation of Engineering in Nigeria) as a practicing engineer, IN ADDITION to a recognized international body (IMechE, ASME, or equivalent).
• Demonstrable hands-on expertise with at least two of the following commissioning/completions software platforms: SPI, Cimplicity, Completion Manager, or an auditable equivalent, with documented evidence of use (project reference letters required, not self-declared).
• Valid, current certifications in: BOSIET/HUET (with CA-EBS) not more than four (4) years old, OPITO-approved Offshore Survival, Confined Space Entry & Rescue, and Working at Height — all must be renewable within the contract mobilization window.
• Demonstrated track record of having personally led (as lead/senior engineer, not team member) the mechanical completion of a minimum of three (3) crude/hydrocarbon storage tank projects of 10,000 bbl capacity or greater, independently verifiable via client reference contacts.
• Fluent, unambiguous technical English — written and spoken — sufficient to independently author and defend commissioning procedures and punch-list justifications to client and third-party auditors without supervision.
• Must possess a valid NUPRC/DPR-recognized offshore medical fitness certificate and be able to pass a pre-mobilization medical examination without restriction.
• Must be immediately available for continuous offshore rotational deployment (28 days on / 28 days off minimum) for the full contract duration.

Mandatory Requirements:

• Qualifications and professional certifications must be issued by recognised bodies, current where applicable, and independently verifiable.
• Expired, unverifiable, or attendance-only certificates will not satisfy a mandatory requirement.
• Candidates must demonstrate recent experience on comparable oil and gas projects.
• Generic construction experience without direct tank, terminal, refinery, process-plant or offshore exposure will not be accepted.
• Candidates must be able to interpret engineering drawings, specifications, inspection and test plans, permits, risk assessments and applicable codes, and must produce clear technical reports in English.
• Candidates must demonstrate strong process-safety awareness, stop-work discipline, quality ownership and effective collaboration in a live brownfield environment.
• All offshore survival, medical and safety credentials specified for the role must be valid before mobilisation.
• Any offer remains conditional upon medical fitness, background checks and client approval.
• Applicants must be available for technical interviews, certification checks and practical or scenario-based assessment at short notice.
