Mission
POSITION SUMMARY
SEGULA Technologies is seeking an experienced Refrigerated LPG Tank Specialist to provide technical expertise in the engineering, design review, fabrication, inspection and commissioning of refrigerated LPG storage tanks and cryogenic containment systems.
The successful candidate will assess engineering documentation, verify compliance with applicable technical standards, evaluate equipment integrity and support quality assurance throughout the project lifecycle.
MAIN RESPONSIBILITIES
- Review refrigerated LPG tank concepts, design philosophies, design criteria and technical specifications.
- Assess engineering calculations, drawings, technical reports, datasheets and vendor documentation.
- Verify compliance with applicable South African regulations, project requirements and recognised international standards.
- Review tank construction arrangements, including bottom plates, shell structures, roof systems, penetrations and associated components.
- Assess cryogenic materials selection, insulation systems, thermal performance and structural integrity.
- Review boil-off gas management interfaces, pressure and vacuum protection, and associated safety provisions.
- Evaluate tank design provisions for operational safety, maintainability, inspection accessibility and long-term integrity.
- Review fabrication procedures, welding documentation, inspection and test plans, quality records and technical deviations.
- Support technical assurance during tank fabrication, installation, preservation, testing and pre-commissioning.
- Witness or support selected inspections, leak testing and other acceptance activities, as applicable.
- Review cold-commissioning readiness and cooldown procedures.
- Coordinate technical interfaces with civil and structural, process, piping, electrical, instrumentation, control and fire protection disciplines.
- Assess cryogenic foundation interfaces, including thermal protection and settlement monitoring.
- Participate in interdisciplinary design reviews, HAZID, HAZOP, SIL workshops and constructability reviews, where relevant.
- Maintain technical review registers, comment-resolution records and non-conformance documentation.
- Identify and escalate technical risks, deviations and quality issues.
- Support commissioning, start-up and operational handover activities.
TECHNICAL RESPONSIBILITIES
- Provide specialist mechanical engineering expertise for refrigerated and cryogenic storage systems.
- Review engineering deliverables and recommend acceptance, rejection or clarification within delegated authority.
- Identify technical risks, non-conformances and corrective actions.
- Coordinate with engineering, procurement, fabrication, construction and commissioning teams.
- Maintain independent technical judgement and ensure review findings are documented and resolved.
Profil
REQUIRED QUALIFICATIONS
