About Layline

Layline started with a news story about how often laytime claims turn out to be miscalculated. I read it and couldn’t let one thought go: laytime is deterministic math. The terms are defined — the BIMCO Laytime Definitions 2013 exist precisely so the words mean one thing. And yet the money — six and seven figures per claim — is still decided by spreadsheets rebuilt by hand for every voyage, from Statements of Facts typed in line by line, under deadline pressure.

Layline is a deterministic laytime engine. Every rule it applies is traceable to a named BIMCO 2013 definition. Money is computed in exact decimal arithmetic — no floating-point drift, no rounding surprises. Every timestamp is handled in UTC. The same Statement of Facts produces the same laytime statement, every time, and every interruption and exclusion on that statement cites the rule behind it.

I’m not a former demurrage analyst, and I won’t pretend to be. That’s exactly why Layline is built to show its work: nothing in a statement is a judgment call you have to take on faith. Check any line against the SoF and the definitions. You shouldn’t have to take my word for anything — and you don’t.

How SoF data is handled, stored, and deleted is written down plainly on the security page. Mutual NDA before any live document, if you want one.
