Each service exists to answer one question with evidence: how much, what quality, and who is accountable for the difference.
WPSL assists government agencies on revenue drives by ensuring the correct methodology is adopted in assessing both quantity and quality — and reported accurately — boosting national revenue through careful classification, valuation and risk management.
We research, design and implement cutting-edge infrastructure, and help government agencies re-engineer complex operational processes with the right technology. If the constraint has a physical solution, delivering it cost-effectively is our job.
We work closely with governments to protect their interests around verification of quantity — as technical partner to Specialist Inspection Service Limited on Sierra Leone’s Export Supervision Scheme, and alongside Global Inspection Services on Nigeria’s pre-shipment inspection of crude oil and gas exports.
Bespoke inspection tailored to each client, covering dry and wet cargoes, crude oil and refined products — plus terminal audits, loss-control investigation and tank cleaning. We conduct independent qualitative and quantitative analysis on vessel and on the exporter’s storage tanks.
Our staff participated fully in Nigeria’s destination inspection era (2006–2013), building deep skill in valuation, classification, risk detection, scanner maintenance, assessment, profiling and forecasting — expertise we now apply to clients’ own computerised risk-management systems.
Strategically located to serve West African operations, our laboratories — held in association with technical partner Stewart Inter Sea Ltd (SISA) — offer a comprehensive range of chemical and petroleum analyses, continually upgraded for accuracy and speed.
