API 653 Tank Inspector

Ereyi Ventures Nigeria Limited

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.

Application Closing Date
Not Specified.

How to Apply
Interested and qualified candidates should send their CV to: [email protected]using the Job Title as the subject of the mail.

Application Package

  • A detailed curriculum vitae stating the position title and reference number.
  • Copies of academic qualifications, professional registrations and all mandatory certificates, including certificate numbers and expiry dates.
  • A project-experience schedule covering at least three relevant assignments and stating client, facility, dates, scope, exact role, achievements and a contactable referee.
  • Evidence supporting role-specific experience claims, such as redacted appointment letters, client approvals, signed reports, logbooks or completion certificates.
  • Current availability and earliest mobilisation date.

Important Note

  • Incomplete applications or applications that do not clearly demonstrate every mandatory criterion may be screened out without further correspondence.
  • Only shortlisted candidates will be contacted.

Selection standard

  • The criteria in this document are deliberately rigorous.
  • Appointment is subject to documentary verification, certification-registry checks, a technical interview or practical assessment, client acceptance and fitness to mobilise. Meeting the minimum requirements does not guarantee shortlisting.

Employment basis

  • Project-based engagement. Rotation, mobilisation date, contract duration and commercial terms will be communicated to shortlisted candidates.

Recruitment and Compliance Notice

  • All appointments are subject to verification of identity, qualifications, employment history, professional standing, medical fitness, offshore survival status, references and client-specific competence requirements.
  • The employer reserves the right to conduct written, oral, practical and scenario-based assessments and to withdraw an offer where information is inaccurate, incomplete or cannot be verified.
  • The successful candidates will be required to comply with project HSE rules, quality plans, information-security controls, anti-bribery requirements, confidentiality obligations and all lawful site instructions.
  • No candidate may perform work outside the limits of his or her verified competence or certification authority.
  • Applications will be considered on merit and role-related competence. Reasonable accommodation may be provided during the selection process where requested and practicable, without reducing the essential safety and technical requirements of the role.
  • Application instructions and the closing date will be stated in the publication notice.
  • Applicants must use the position title and reference number as the email or portal submission subject.
