DemurrageIQ turns owners' demurrage claims into defensible counter-positions — in minutes, not days. Demurrage is one of the largest unmanaged cost items in commodity tanker trade, and owners' claims are routinely overstated. Checking them by hand means wading through charter parties, Statements of Facts and Letters of Protest, port by port. DemurrageIQ does it for you. It reads the charter party (or the fixture recap), the SOFs and the LOPs, calculates laytime automatically — reversible or per-port, fixed hours or rate-based — and produces your independent laytime calculation, a defensible counter-position against the owner's figure, and a ready-to-send counter-claim letter. Every deducted hour is traced back to the source document. Built for charterers, trading houses and brokers moving chemical, biofuel and clean petroleum products.
