What is CSMTS?
The CSMTS – Critical System Monitoring and Tracking System is a stand-alone data acquisition, recording, communications and transmission product developed by Fathom Systems.
Installed by IHC Hytech for Oceanwide Safety at Sea, the system meets and exceed the current guidelines and requirements for the safe operation of self-propelled hyperbaric lifeboats (SPHL) in the event of an evacuation from the host Dive Support Vessel (DSV). The product is a multi-unit system that is an industry wide requirement as stipulated in OGP Report 478 (7.4) and an essential element of the hyperbaric evacuation plan set out in the IMCA D052 guideline document.
Basic System Capability
The system transmits critical sensor and mission data from the SPHL to shore via the low level ‘Iridium®’ satellite communications network via two antenna mounted in a suitable position on the topside of the craft. A terrestrial server system managed by Fathom Systems receives the data which is then distributed via the Internet to allow remote monitoring and incident management of the SPHL from any location globally either on land or at sea. The DSV Operator has access to all data from the terrestrial servers via the Internet connection and a ‘Client-side’ application allows bi-directional data transfer between incident rooms and the SPHL.
The ‘Iridium®’ satellite communications system provides automated data transmission of the measured parameters and also provides voice communications via a handset for the SPHL crew to allow bi-directional calls to any telephone number globally and initiated by either party. The existing voice link to the SPHL chamber communications system also permits rescue personnel to talk to divers inside the chamber via the satellite telephone link and through the on-board helium speech unscrambler. The Fathom Systems CSMTS is compatible with all existing manufacturers voice communications systems installed on SPHL’s.
As the service provider, Fathom Systems automatically monitors the status of all equipped SPHL’s continuously. In the event of a launch, an immediate alert is received allowing the shore based response teams to be notified by telephone, SMS or e-mail. Automated periodic ‘health check’ interrogation ensures a fail-safe and direct system availability.
The on-board HMI is a Panasonic Toughpad mounted in the cockpit of the SPHL at the life support panel and hosted by the master data acquisition unit (MDAU).
Enhanced system capability
The system can be optionally extended to provide additional capability including;
- Biomedical instrumentation worn by the divers to measure heart rate, temperature, respiration rate and monitoring of specific medical instruments in the chamber (eg;blood pressure monitor, O2 saturation etc.)
- Global emergency broadcast / identification system permitting all authorised emergency services to monitor the status of any incident via the Internet and to provide advisory information to these authorities such as interface trunk size and position, emergency life support package connection details, numbers and details of occupants, details of DSV Operator and emergency response numbers etc.
- Automatic hand-over from vessel based diver monitoring systems (DMS) to the SPHL based CSMTS system including diver’s individual historical exposure profiles for current saturation period. This will allow remote management any therapeutic treatment of specific divers and management of decompression profiles either in the SPHL or at the onshore hyperbaric reception facility (HRF)
- Black box voice recording providing 72 hours of saved communications of the SPHL crew-divers
