🔍 Key Concepts

• Transverse stability (tendency to list port or starboard) when removing weight high and to the sides • Effect of discharge sequence from wing tanks vs. centerline tanks on ship’s stability and list • Importance of keeping the vessel upright and safe throughout cargo discharge

💭 Think About

• If you remove cargo from the sides first, what happens to the ship’s list and GM (metacentric height)? • Which group of tanks, when discharged first, is more likely to help keep the vessel upright rather than develop a list? • Before thinking about bow or stern trim, what is the very first stability concern when starting cargo discharge?

✅ Before You Answer

• Compare how emptying wing tanks first versus centerline tanks first affects list and transverse stability • Consider which option best helps maintain an even keel and upright condition at the start of discharge • Verify which practice is emphasized in tanker stability and cargo-handling procedures as the initial stability consideration
