Ereyi Ventures Nigeria Limited is an indigenous Engineering, Procurement, Construction, and Logistics (EPCL) contractor providing integrated technical services to the Nigerian oil and gas industry. The company brings a multidisciplinary team of engineering, inspection, and construction professionals to deliver brownfield and greenfield projects across onshore and offshore facilities, with a focus on asset integrity, tank and vessel upgrades, mechanical and instrumentation works, and terminal automation. Leveraging local content expertise alongside international codes and standards (API, ASME, NACE/AMPP, and IEC), Ereyi Ventures is positioned to execute the Automated Crude Oil Storage Tanks Upgrade and Repair Services at an offshore terminal, combining indigenous capacity with the technical rigor required for safety-critical hydrocarbon storage infrastructure.

We are recruiting to fill the position below:

Job Title: API 653 Tank Inspector

Reference no: TKI-06
Location: Offshore, Delta

Role Objective

• Act as the competent tank inspection authority for condition assessment, repair acceptance and return-to-service certification of aboveground crude-oil storage tanks.

Core Roles and Responsibilities

• Plan and execute in-service and out-of-service API 653 inspections of crude oil storage tanks, including shell, floor, roof, and appurtenance assessment.
• Determine tank inspection intervals and repair/alteration requirements in accordance with API 653, API 650, and API 575.
• Review and interpret NDT results (UT thickness surveys, MFL floor scans, vacuum box testing) to assess tank fitness-for-service and remaining corrosion allowance.
• Prepare formal Tank Inspection Reports, including settlement surveys (per API 653 Annex B), corrosion rate calculations, and minimum required thickness determinations.
• Issue engineering recommendations for repair, alteration, or re-rating of tanks, coordinating directly with the Pressure Vessel Engineer/API 510 Inspector, Structural Engineer, and Metallurgist where cross-discipline input is required.
• Witness and approve repair welding, patch plate installation, and floor/roof replacement work for code compliance prior to tank return-to-service.
• Maintain the tank inspection history file and long-term integrity management/RBI (Risk-Based Inspection) data for the storage tank fleet.
• Liaise with NUPRC and other regulatory bodies on tank integrity compliance documentation as required.

Qualifications and Requirements
This is the single sign-off authority for tank fitness-for-service; the certification bar is intentionally uncompromising.

• B.Eng./B.Sc. in Mechanical, Metallurgical, or Petroleum Engineering, minimum Second Class Upper, from an accredited university.
• Current, valid API 653 (Aboveground Storage Tank Inspector) certification issued by the American Petroleum Institute — certification must not be due for renewal within twelve (12) months of the contract start date.
• Additionally mandatory: valid API 570 (Piping Inspector) OR API 510 (Pressure Vessel Inspector) certification as a secondary credential — single-certification candidates (API 653 only) will not be considered for this role given the cross-discipline nature of the terminal.
• Ten (10) years cumulative experience in storage tank inspection within the oil & gas industry, of which no fewer than five (5) years must be post-API 653 certification, hands-on, chargeable inspection work (not administrative/QA oversight only).
• Minimum three (3) documented, independently verifiable full tank out-of-service inspection projects led as lead inspector (not assistant), each on tanks of 10,000 bbl capacity or greater, with client reference letters naming the specific tanks and dates.
• Certified Welding Inspector (CWI – AWS) as an additional, mandatory qualification, given the extent of weld repair oversight required on this scope.
• Demonstrated working knowledge of API 579 (Fitness-For-Service) sufficient to independently perform Level 1 assessments — Level 2/3 FFS training/certification will be scored significantly higher.
• Minimum five (5) years offshore/marine terminal experience specifically (inland tank farm experience alone does not satisfy the offshore requirement of this role).
• Valid BOSIET/HUET, offshore medical fitness certificate, and full readiness for extended rotational offshore deployment.
• Must successfully complete a written and practical technical assessment (including live interpretation of UT/MFL scan data and settlement survey calculations) during the interview process.

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.
