MarineSchedule is the real-time communication app for ship repair industry. We believe MarineSchedule brings communication channels of ship repair industry into the digital age from the Stone Age. Time is the most valuable asset to everyone and time is money in business. So, ship repair process must be finished on time without any delay. There are many participants from Ship Owner, Shipyard and Classification Societies. For the time management, real-time communication between participants about ongoing concerns on ship repair process is important. However, traditional way of communication faces difficulty in making sure every participant on the same page, especially for participants working at different location and time zone. It often leads to unexpected delay of ship delivery. MarineSchedule provides the best solution for real-time communication based on time management. As a mobile app service, MarineSchedule registers the ship in repair and invites all participants involved. In line with work schedule, users can easily report any issues with pictures and videos. With quick decision and proper approval, ship repair process can be completed as initially planned.
