The question

Not a client order: a concept. What would a system for a grain shipowner look like?

What we built

Concept

A drawn ship whose holds load as you scroll, and a laytime clock that turns a statement of facts into a demurrage bill.

Concept 01 · For Prelude Marine

The clock that bills.

Factories are not the only places where time turns into money. A bulk carrier waiting in port does too. This is a working sketch of the system we would build for a grain shipowner: what is in every hold, and what every hour in port costs.

Act 1

Every hold, seen from the deck.

Move over the hull to look inside.Hold to look inside. Scroll to load 25,000 t.

Five holds. The five cargoes Prelude Marine carries most. Urea and phosphate out, wheat and barley back: the same holds carry what grows the grain, and the grain.

Urea and phosphate out, wheat and barley back: the same holds carry what grows the grain, and the grain.

Same 25,000 t, different space: barley fills 99% of the holds, phosphate 64%.

Stowage factor 1.28 m³/t · typical · One centimetre on the draft marks is about 39 tonnes of cargo.

    Act 2

    From the statement of facts to the bill.

    Laytime is the time the charter allows for discharge. When it runs out, every extra hour is billed as demurrage. The charter’s wording decides which hours count.
