🔍 Key Concepts

• Cargo quality control and contamination checks during loading/discharge • Why samples from different system points (shore side, ship side, transfer line) might be important • Responsibility for proving where any contamination or off‑spec product originated

💭 Think About

• If the cargo is later found off‑spec, from where would you need samples to prove whether the problem came from shore, ship, or pipeline? • Does taking a sample from only one place let you isolate the source of contamination, or do you need comparative samples? • In real operations, where do surveyors and inspectors typically draw their ‘reference’ and ‘line’ samples during an oil transfer?

✅ Before You Answer

• Make sure you consider both ship and shore sampling points, not just one side • Think about which sampling plan gives you the best evidence trail in case of a cargo quality claim • Ask: Is there any option that clearly omits a critical point in the transfer system?
