# Vessel Vetting: What It Means for Suppliers > Vessel vetting explained for suppliers: how SIRE and CDI inspections work, and how to use vetting outcomes to choose which tankers to target before arrival. URL: https://vesselreach.si/blog/vessel-vetting-what-it-means-for-suppliers | Published: 2026-10-23 | Guide | Topic: Reaching decision-makers at ship managers Vessel vetting is the process by which oil majors, charterers and terminal operators check a tanker's inspection history before fixing it or accepting it at a berth. For suppliers, vetting results are a free targeting signal: they show which tankers are actively trading with the majors and which ship managers are investing in inspection performance. ## What does vetting mean in shipping? Vetting is a commercial fitness check, separate from flag and port state control. It relies on inspection reports such as SIRE (Ship Inspection Report programme) and CDI (Chemical Distribution Institute) that charterers and terminals review before approving a vessel. A 2023 study in the International Journal of Environment and Geoinformatics describes SIRE VIQ inspections as one of the additional inspection mechanisms that complement regular flag state and port state inspections on oil and chemical tankers ([IJEGEO](https://doi.org/10.30897/ijegeo.1291867)). Vetting is not a single certificate. It is a continuous record. A ship manager's ability to keep that record clean determines which cargoes its tankers can carry and which charterers will use them. ## Why the inspection burden keeps growing Tanker inspections have multiplied because more stakeholders now demand their own assurance. A 2019 study in the Journal of Computer and Communications notes that major oil companies, port states, classification societies and flag states have all increased the number of tanker inspections due to safety concerns ([Journal of Computer and Communications](https://doi.org/10.4236/jcc.2019.71003)). The overlap is significant. A 2017 study in PROMET found that more than 60% of surveys overlap each other and proposed a unified regime that would cut annual inspection duration by up to 30% ([PROMET](https://doi.org/10.7307/ptt.v29i4.2362)). For a ship manager, every inspection is a cost and a risk. For a supplier, that pressure is a buying signal. Managers who are actively managing inspection performance are also managing the supply chain that supports it: spares, provisions, chemicals, technical services and port attendance. ## How vetting outcomes reveal a target list You do not need to read a SIRE report to use vetting as a filter. You need to know which tankers are trading in vetting-sensitive trades and which managers are investing in compliance. - **Trade pattern:** tankers on oil major business face regular SIRE inspections. Their managers buy technical and port services to keep those inspections clean. - **Inspection age:** a vessel due for its next inspection window is a vessel whose manager is preparing. That preparation includes spares, documentation and often additional port attendance. - **Fleet changes:** managers adding tanker tonnage inherit inspection obligations. A 2026 Splash247 report describes a Chinese investor seeking control of Hong Kong-listed asphalt tanker operator Xin Yuan Enterprises through a cash offer of up to HK$771m ([Splash247](https://splash247.com/chinese-shipping-investor-makes-play-for-asphalt-tanker-owner-xin-yuan/)). Ownership changes often bring procurement reviews. - **Newbuild programmes:** new tankers enter service with fresh inspection schedules. Transpetro, the logistics arm of Petrobras, has begun construction on a 13-vessel order in Brazil ([The Maritime Executive](https://maritime-executive.com/article/tanker-operator-transpetro-s-fleet-expansion-creates-local-jobs-in-brazil)). ## Where the supplier fits in the vetting chain Vetting creates demand for documented, traceable supply. A tanker preparing for a SIRE inspection needs its engine room, deck and safety equipment in order. That means spares with certificates, chemicals with safety data sheets and service attendance that can be evidenced. Procurement pressure is moving toward centralised visibility. AVS Global Ship Supply has launched a digital platform that brings ordering, expenditure, inventory and operational records into a single system for ship managers ([Hellenic Shipping News](https://www.hellenicshippingnews.com/avs-targets-fragmented-vessel-procurement-with-centralised-fleet-management-platform/)). Suppliers who can present clear documentation and consistent pricing fit that model better than those who cannot. The cost conversation is also shifting. As The Maritime Executive notes, when a vessel needs a spare part, someone ashore owns the problem of finding a supplier, comparing quotes and checking lead time ([The Maritime Executive](https://maritime-executive.com/article/maritime-procurement-where-the-cost-is-really-set)). That person is your real buyer, and vetting performance is part of what they are judged on. ## Which tankers to target first Use vetting as one filter among several. A practical order of priority for a chandler, bunker supplier or repair yard: 1. Tankers on oil major or chemical trades with an inspection window approaching. 2. Vessels whose managers have recently added tonnage or changed ownership. 3. Newbuilds entering service, where inspection schedules are starting fresh. 4. Tankers trading in regions where port state control attention is high. Then check who buys. The technical superintendent or purchasing superintendent usually owns supplier selection for inspection-related work. The operations team controls port attendance. Reaching both before the vessel arrives is the difference between being on the approved list and being a last-minute call. ## How VesselReach helps VesselReach turns vessel movements into a vetting-aware target list. You select your ports, and the platform shows tankers near or expected at those ports, so you can approach the right manager before the inspection window or port call arrives. - **AI company targeting** identifies the ship manager, owner or operator behind each tanker, which means you spend time on fleets that actually buy your services. - **Decision-maker discovery** finds technical, purchasing and operations contacts by role, which means your message reaches the person who owns inspection-related supply. - **Staged email, WhatsApp and phone outreach** with automated follow-ups keeps your approach consistent, which means fewer missed opportunities when a manager is preparing for an inspection. Book a VesselReach demo to see how vessel intelligence and decision-maker discovery work together for your ports. ## Frequently asked questions ### What is ship vetting? Ship vetting is the process by which oil majors, charterers and terminal operators check a tanker's inspection history before fixing it or accepting it at a berth. It is a commercial fitness check, separate from flag and port state control, and relies on inspection reports such as SIRE and CDI. ([International Journal of Environment and Geoinformatics (IJEGEO)](https://doi.org/10.30897/ijegeo.1291867)) ### What is SIRE inspection in shipping? SIRE is the Ship Inspection Report programme: tanker inspections whose reports charterers and terminals review before approving a vessel. A 2023 study in the International Journal of Environment and Geoinformatics describes SIRE VIQ inspections as one of the additional inspection mechanisms that complement regular flag state and port state inspections on oil and chemical tankers. ([International Journal of Environment and Geoinformatics (IJEGEO)](https://doi.org/10.30897/ijegeo.1291867)) ### What does vessel vetting mean for a ship chandler? Vessel vetting tells a ship chandler which tankers are trading on inspection-sensitive business and which ship managers are investing in inspection performance. Managers preparing for a SIRE inspection buy spares with certificates, chemicals with safety data sheets and evidenced service attendance, so vetting outcomes work as a free targeting signal. ### Why are tanker inspections increasing? Major oil companies, port states, classification societies and flag states have all increased the number of tanker inspections due to safety concerns, according to a 2019 study in the Journal of Computer and Communications. The result is more inspection events per vessel and more preparation work for ship managers. ([Journal of Computer and Communications (Scientific Research Publishing)](https://doi.org/10.4236/jcc.2019.71003)) ### Which tankers should a supplier target first? Start with tankers on oil major or chemical trades whose inspection window is approaching, then vessels whose managers have recently added tonnage or changed ownership. Newbuilds entering service are also worth tracking because their inspection schedules start fresh. The technical or purchasing superintendent usually owns supplier selection for inspection-related work. ### How does VesselReach help suppliers use vetting as a targeting signal? VesselReach shows tankers near or expected at your chosen ports, uses AI to identify the ship manager, owner or operator behind each tanker, and finds technical, purchasing and operations decision-makers by role. Staged email, WhatsApp and phone outreach with automated follow-ups keeps your approach consistent before the inspection window or port call arrives. ## Sources 1.

For suppliers, the vetting process meaning goes beyond compliance: it shows which tankers are trading on inspection-sensitive business and which ship managers are likely to buy documented, traceable supply. SIRE and CDI inspections create demand for spares, chemicals and port services. Managers preparing for an inspection window are active buyers. Use vessel arrival data to reach the technical or purchasing superintendent before the vessel berths, and track fleet changes and newbuilds as additional signals. What is ship vetting inspection? It is the report-based check oil majors and charterers run on a tanker's inspection history before fixing it, using SIRE and CDI reports. What is a SIRE inspector looking at? The condition of engine room, deck and safety equipment, which is why managers preparing for an inspection buy certified spares, chemicals with safety data sheets and evidenced service attendance. Which tankers should a chandler approach first? Those on oil major or chemical trades with an inspection window approaching, plus vessels whose managers recently added tonnage or changed ownership. The technical or purchasing superintendent usually owns supplier selection, so reach that person before the vessel berths. --- VesselReach, built by CatalystIQ.
