DP ALERT SYSTEM UMAS: PRECISION, RELIABILITY AND ACCESSIBILITY OF INFORMATION
UMAS is a DP Alert system for ROV, Diving and Cranes operations, associated to a signaling light system of the vessel’s Dynamic Positioning mode state.
It clearly indicates the condition of the equipment during the operations and it passes on reliable information.
Thanks to this device, staff, especially the staff with responsibilities, can be informed from the wheelhouse, the engine office, clients offices, cafeterias, crew quarters and cabins, of whether a ROV and/or a Sat Dive is upwelling on the deck as well as of the DP alarm signals (green, blue, yellow and red).
UMAS is useful to MPSV, Drill ships and oilrigs. |
 |
UMAS is :
 |
• LEDs display panels, located in common areas, operations offices, cabins andcranes, which give information about the equipment operation mode
• local control panels, placed in ROV and Sat Dive operations offices, on which the operating mode is chosen and the DP alarm is validated; in cranes too in order to know when they are operating
• one main panel in the wheelhouse, to give the “green light” to ROV and Sat Dive operations control offices, and which displays the state of the DP alarm system and the acknowledgements from the different operations offices simultaneously |
AN INOVATING TECHNOLOGY: THE POWERLINE COMMUNICATION
|
UMAS uses the Power Line Communication technology. Display and control panels are connected to a single cable and data are carried on 2 conductors which are also simultaneously used for electric power transmission.
This technology offers:
- wire weight reduction
- time saving in wiring
- saving costs
- perfect synchronization of signals
- online monitoring of each component
UMAS can have up to 20 LEDs displays per line, thus offering a wide access to information. |

UMAS ADVANTAGES: VISUAL INFORMATION, SECURITY, SPECIFICITY, ADAPTABILITY
|
•It gives visual information
Information is transmitted with light signals. It is simple, clear and precise. This system supports the oral instruction. Possible misunderstandings are avoided.
• It gives accessible information
Equipment and DP signalization information can be seen by everyone, and in particular staff with responsibilities and clients. Indeed, information can be seen from the wheelhouse, the PC control, ROV and Sat Dive control offices, cabins, common areas and any other place where the client would find it necessary.
• It specifies information
Each equipment has its own lights: green, yellow and red LED, indicating for example a ROV or a Sat Dive is under water, upwelling or on deck; or in case of a crane on a drillship or a rig, if it is operating or stopped.
• It gives security to work
Two steps in the green light authorization process in order to check that the instruction is well understood and registered: authorization (flashing light), then validation (steady light).
• It gives security to information
All button actions from panels are recorded on a memory card. Thus, the historical record is automatic and more reliable.
• It is flexible and upgradeable/ evolving / evolutionary
Thanks to Power Line Communication, the numbers of DP alarm information boxes can go up to 20 displays per line. According to the client’s needs, panels can be added wherever on board, thus ensuring the entire satisfaction of the clients’ demand.
• It is easily installed:
The Power Line Communication technology is easy and quick to install on new vessels as well as on those already operating. |
