SOLO is intended to supplement existing "dead-man" alarm systems required for UMS operations.
It is often the case that duty engineers will find themselves alone in the engine room for prolonged periods i.e. during standbys, when the ship is under pilotage, transiting confined waters or undertaking general nightly duties.
Whilst the "dead-man" alarm is available, experience shows that it is often under used due to the perceived inconvenience of having to press a reset button at pre-determined intervals especially during periods of repair or insufficient reset points..
SOLO protects the engineers - whilst in the ECR - by detecting their movements using PIR motion sensors. Should an engineer remain motionless, through incapacity or otherwise, beyond the set time period a pre-alarm is activated. Failure to respond to this warning will result in the main alarms being activated. If still unacknowledged the ship's alarm will be triggered leading, eventually, to the engineer's call system alerting off duty engineers to a possible problem in the ER.
When outside the ECR the engineers have access to portable wireless reset / call key fob transmitters and / or fixed manual reset buttons situated around the engine room.
These manual reset buttons and / or wireless reset / call transmitters are also programmed to be used as emergency "Call for Assistance".
Incapacitated Personnel Location
It's one thing knowing there’s a man down, it’s another finding them quickly. The sooner the injured person receives attention the better, to this end a portable 140db personnel location alarm can be provided.
