“Man Over Board” safety system

Introduction

Even in the commercial shipping safety of crews comes first. Therefore, ABS-TT offers in this area two innovative solutions that ensure a secure protection for each team member.

CREWSAFE is a network solution for ships, oil rigs and other locations, which is realized with the so-called tags are worn by the team members.

V100 PLB is a stand-alone solution with GPS and emergency capabilities for gone overboard crew members. It allows discovery within the water from ships, stations, aircraft and helicopters.

CREWSAFE

The Crewsafe tag is a personal receiver that is worn by all team members to connect them with the Crewsafe network. Mobilarm Crewsafe ^® is a wireless network that was designed to improve the job security of maritime labor, too. By Crewsafe the movements of the entire crew are pursued during working hours and in an emergency alarm.

A number of wireless routers to create a Monitoring and Message Network that automatically detects people with emergencies involving a matter of seconds and triggers an alarm, such as for man overboard.

Each employee wears a small receiver – a so-called “Crewsafe tag” – the wireless signal connects it with the network of Crewsafe router. The network immediately detects the termination of a signal and triggers the alarm if the connection is not established within a few seconds. Where an employee goes overboard, the signal is interrupted and the alarm is triggered automatically. The Crewsafe tag provides an additional emergency button which can be activated manually when a worker is in a different predicament.

Protection is provided by this technology with a fail-safe principle, which means that any termination of the trigger signal, for any reason triggers an alarm. When the tag will be damaged if the battery fails or a person moves out of the reach of the network, the alarm is triggered, and ensures that all employees will be informed immediately, regardless of whether it is a real emergency, a product defect, or just a removal from the safety zone.

If it is installed on ships, the Crewsafe network can be connect with existing navigation and GPS systems. In a man-overboard (MOB) emergency situation Crewsafe automatically logs a waypoint on the plotter of the ship for the post mark where the incident took place. It provides necessary data in order to easily find the location using the navigation. The system can display multiple incidents and track them, but it automatically prioritized serious incidents, such as “man overboard”, over other events.
