Sea Roster mobile application manages the on-board requirements for compliance with crew work and rest hour regulations (IMO STCW 2010, ILO Work (MLC), ILO Rest (MLC), OCIMF and ILO Work (MLC) + Japanese Seafarer Union recommendations). The app closely monitors any repeat deficiencies and adjusts future working routines on-board to prevent excessive working hours and reduce fatigue onboard. Sea Roster can act as a standalone module and is can also be integrated with other applications. The seafarers can efficiently update planned and actual work/rest hours using the SeaRoster app
