Ship Security Alert System

StratumFive offers a range of Ship Security Alert Systems that provide significant operational value for ship operators that are either looking to upgrade their existing INMARSAT D+ SSAS, consolidate their fleet with a single provider or simply wish to improve security with a dedicated standalone system.



SeaGuard is a PREMIUM dedicated SOLAS X1.2.6 type approved standalone system that operates on the new INMARSAT IsatDataPro (IDP) satellite network. Designed to exceed regulations with the addition of an internal backup battery module, on board test functions, up to two separate alert zones and GPS jamming notification. New installations come inclusive of all cabling and alert button requirements. If upgrading from legacy D+ SSAS systems, operators can take advantage of utilising existing SSAS cable runs, reducing upgrade or consolidation deployment and avoiding any technician charges.


SeaGuard Alert Service

SeaGuard is automatically integrated with our OTiS software that will receive and direct all Ship Security Alerts to the company security officer, competent authorities, regional co-ordination centres, high risk patrols and or flag authorities via priority email and SMS . By integrating your SSAS into OTiS there is no need to have multiple recipient addresses stored and maintained at terminal end. Furthermore OTiS will be able to configure and control SSAS terminal tests in a supervisory status, reducing time and resources during periodical maintenance. Clients will also benefit from unlimited alert recipients and the ability to remotely reset terminal in alert.


SeaGuard Tracking Service

Tracking is a standard provision with our alert service. SeaGuard automatically transmits a daily system report inclusive of position, course and speed. These reports can be increased to provide a vessel tracking service. The frequency of position reports can be automatically adjusted from once a day down to every 15 minutes depending on individual tracking or monitoring needs. The tracking reports are instantly displayed via our online tracking and information software, OTiS.


SeaGuard Online Software

OTiS instantly displays security alerts and automatic position reports sent from the SeaGuard and referenced against real time location based information to provide users with a detailed view of a vessel’s movements and performance with configurable email notifications. OTiS also correlates meteorological observations, forecasts, tropical storm warnings and piracy activity against vessel positions serving a complete fleet tracking and optimisation solution. The comprehensive security alert module manages alert messages and recipient lists as well as simplified testing functions with audit trails.
