10 triAlity vlcc A ballast-free design A conventional vlcc carries sea water as ballast in transit in unloaded condition and during loading and discharging in port. ballast water is used by all vlccs today for two purposes: • to achieve sufficient draft and suitable trim • to control hull stress levels the ballast operations have two main unwanted effects: • ballast water may contain organisms that can cause damage when released into foreign ecosystems. this is why the imo has established the international convention for the control and management of ships’ ballast water and sediments. expensive ballast treatment systems will also increase fuel consumption. • Additional fuel is needed to transport 80–100 000 tons of ballast water. triality has a ballast-free design with the following characteristics: i. new transverse cargo tank divisions enable cargo tanks to be loaded without the need for ballast for strength or trim/heel compensation ii. the new v-shaped hull form provides sufficient draft without cargo or ballast iii. the new hull shape has a mean average of 16% less wet surface on a roundtrip, a lower block coefficient and is 11% more energy efficient
the new hull shape is designed for sufficient draft, even in an empty condition. new cargo tank divisions eliminate the need for ballast, including during cargo operations.
