Cargo hold section
A midship hold section with hopper and topside tanks fills from the hatch centreline, the cargo surface rising through the section against the depth scale.

15 animationsDraught survey
Six draught stations around a hull plan are read in turn and the surveyed displacement bar settles onto the cargo figure once the last one is taken.
CSSPremiumGrab discharge cycle
A clamshell grab lowers into a hold, closes on a bite, lifts clear and opens over the hopper while the cargo level in the hold steps down.
CSSPremiumGrain trimming
A heaped grain surface under a loading spout is levelled pass by pass until the crown flattens to a trimmed line and the void above it closes.
CSSPremiumHull girder stress
A bending moment curve along the ship's length swells toward its limit envelope as the holds load and is pulled back inside it when the pour order is corrected.
CSSPremiumInert gas blanket
Inert gas fills the ullage space above a cargo tank and the oxygen reading falls down its scale until it settles below the eight per cent rule.
CSSPremiumLine segregation
A spectacle blank at a manifold crossover turns from open to blind, the flow along the shared line stopping and the two grades routing to separate drops.
CSSPremiumLNG boil-off
Vapour rises from the liquid surface of a membrane tank into the dome and the tank pressure needle is drawn back into its band each time the vapour is taken away.
CSSLoading sequence
Five holds take their pours in planned order rather than left to right, the active pour marker stepping between them while the ballast column drains alongside.
CSSPremiumParcel stowage plan
A tanker tank matrix takes three cargo parcels into separate blocks, each filling in turn with the segregating tanks between them left empty.
CSSPremiumSelf-unloader boom
Cargo drops from a hold hopper onto a belt, travels up the boom conveyor and builds a shore stockpile cone that grows at a constant angle of repose.
CSSPremiumShifting cargo
A heaped bulk surface slumps to one side as the section heels and a centreline shifting board arrests it, the heel indicator falling back inside its limit.
CSSPremiumShore transfer rate
Cargo runs from a shore tank through the loading arm into the ship's tank and the flow rate steps down through two notches as the tank comes up to its topping-off mark.
CSSPremiumTank cleaning
A rotating washing machine sweeps its jet arc around a tank section and the residue band on the bulkheads clears behind the sweep.
CSSPremiumUllage gauging
A gauging tape drops from the deck datum to the liquid surface and the ullage dimension closes onto the reading as the volume bar beside it fills.
