Seawise Cadence

Crew hours that hold up.

Seawise Cadence records seafarers' work and rest in 30-minute blocks, checks them live against STCW 2010 and MLC 2006, and adds an AI layer that auto-derives records, explains every non-conformity and flags fatigue risk — built mobile-first for crew.

Why it matters

Attack the data, not the rules. Records that reflect reality.

Attacks the real problem: the data

Pre-fill actuals from rosters, port calls and drills, then confirm — instead of reconstructing a fortnight from memory.

Live compliance, not a monthly surprise

The crew slides to confirm and the engine answers in-compliance / beyond-the-band on the spot, with hours and deadline.

Manning decisions you can defend

Analytics name the rank affected, the evidence and the governing requirement (STCW A-VIII/1, MLC A2.3).

Spot fatigue before it's an incident

Projects fatigue-risk windows from cumulative rest deficits and warns when a drill falls in projected rest.

How we compare

Every incumbent is a manual retrospective timesheet with a rules engine.
