Sound familiar?
Every desk has that one spreadsheet nobody trusts.
A workbook from 2015.
Inherited from someone who left. Hard-coded flat rates, a broken cell nobody dares touch, and no version anyone agrees on.
Re-keyed for every voyage.
Same ports, same consumption, same commission — typed in again from scratch. One transposed digit and the TCE is fiction.
Nothing is kept.
You ran the numbers last month on the same route. No history, no audit, no way back to what you actually quoted.
One set of tools. Same answer every time.
Purpose-built for petroleum tankers, kept current, and every calculation saved to your own history.
What's on the desk
Eight tools. One seat.
Everything a broker, owner or charterer needs to price a voyage, argue a demurrage claim, and get the recap wording right.
Cargo Trade
The trader's sums — what the cargo lands at after freight, insurance, financing and demurrage, the margin against the sale, the split by destination, and the freight that still leaves it.
Distance & Route
Real shipping-lane routing with canals, straits, ECA exposure and ETA. Save every voyage you plan and pull it back up later.
TC-in Period
Price a time-charter-in period — hire, commission, ballast bonus and extras — then see break-even employment and your spread.
Voyage & TCE
Freight in, costs out. Commission, port costs, bunkers and voyage days resolved into a time-charter equivalent per day.
Freight & Worldscale
Convert WS points on a flat rate into lumpsum freight, or price a time-charter voyage off a daily rate.
Laytime & Demurrage
Laytime allowed against time used — enter the hours and get demurrage owed or despatch earned at half rate.
Bunker Costs
Estimate a voyage bunker bill from consumption and stem price, with indicative regional levels you can load into the form.
Clause Library
Recap templates and CP clauses — laytime, war risk, sanctions, ETS — with the angle for each side and a rider builder.
Every calculator saves to your history and restores in one click. The clause library copies wording and builds riders from templates.
Distance & route
Try the Route Planner.
No account needed.

Voyage & TCE
Know your TCE before you quote.

Change the rate and every downstream number moves with it — no formula archaeology.

Laytime & demurrage
Laytime in. Claim out.
