The new system brings operational crew communications directly to smartphones using the vessel’s existing onboard Wi-Fi network. It works without an internet or cloud connection, with dedicated departmental channels, centralised management and vessel-based licensing rather than per-user fees.

 Seafy® is expanding its onboard digital ecosystem with the launch of Seafy P2T Push-to-Talk, a system designed for operational communication between crew members.

The solution turns smartphones into push-to-talk devices connected to the vessel’s existing Wi-Fi network. Bridge, engine room, deck and other departments can communicate through dedicated channels even when the vessel has no internet connection.

On board, P2T works entirely offline. When external connectivity is available, communications can also extend to other vessels in the fleet and to the shipping company’s shore-based teams, enabling continuous coordination between ship and shore.

P2T complements the Seafy technology ecosystem by adding a solution specifically designed for crew operations alongside the services already available through its Digital Experience Platform. It addresses one of the most common operational needs on board: enabling crew members working in different areas of the vessel to communicate quickly and efficiently.

Seafy P2T does not replace the radio equipment or safety communication systems required on board, such as VHF and GMDSS. Instead, it provides an additional layer for internal operational communication.

The architecture is based on a server physically installed on board, which manages voice communications, users and channels locally. This allows the system to remain operational throughout navigation while enabling crew members to use devices they already carry rather than requiring an additional radio handset for every user.

When connectivity is available, P2T synchronises with shore-based management tools and enables communication between vessels within the same fleet and with company offices ashore.

Through the iOS and Android app, crew members can access the channels assigned to their department, use push-to-talk communication and exchange messages within an environment controlled by the shipping company.

Voice transmission is initiated in under 100 milliseconds, while talk management prevents simultaneous transmissions from overlapping on the same channel. Different priority levels are also supported, including high-priority communications that can override an ongoing transmission when required.

Traceability is another key element of the system. P2T does not record the audio of conversations. Instead, it stores activity logs locally on the vessel’s infrastructure, including user access, channel activity and transmissions. These records can be reviewed through the management dashboard, providing shipping companies with a history that can support internal monitoring and documentation processes.

Communications are protected, and every access is linked to an authorised user. Identities, roles and permissions can all be managed centrally.

The licensing model is vessel-based rather than user-based. P2T is licensed per vessel, regardless of the number of individual crew members using the system within the selected configuration.

Three configurations are available, covering requirements ranging from yachts and cargo vessels to passenger ships, cruise vessels and larger fleets, with support for up to 1,000 users per vessel. An annual maintenance service is also available.

“A vessel cannot depend on an external connection for its departments to communicate. With P2T, crew members can communicate from their smartphones, on board and without internet access, while the shipping company retains full control of the system.”

Seafy P2T is available both for individual vessel installations and for projects covering multiple vessels within the same fleet.

Shipping companies can start with a live demo, remotely or directly on board, followed by the configuration of the solution according to the vessel’s existing infrastructure and operational organisation.
