A new and innovative mooring line monitoring technology
Direct In-Line Tension Monitoring
In conjunction with Pulse Structural Monitoring, InterMoor has taken its H-Link manufacturing knowledge and combined it with the very latest mooring monitoring technology. Connecting mooring chains together, the Inter-M Pulse will monitor and track the in situ tension for each mooring line and transmit the tension data acoustically to the top side control room interface. The Inter-M Pulse features and benefits are:
-
Full history of mooring line
-
Acoustic data transmission
-
On-demand data upload
-
Traffic light alarm system
-
Topside power not required
-
Deployable over the back of a stern roller
-
Suitable for moored FPSO and MODU
-
Provides crucial information after a storm or hurricane, saving potential downtime
Specifications:
-
Deployable in depths up to 1500 m.
-
Configurable battery options
-
Four main components
-
2 INTEGRIpod AF loggers
-
A standard InterMoor H-link
-
A durable, marine grade plastic shroud
-
A topside data acquisition system
Benefits:
-
A class approved long term mooring connector
-
Direct tension measurement
-
Data available on demand
-
Acoustic transmission eliminating the risk of severed cables
-
Immediate alarm if the tension exceeds preset values
A Proven Technology:
In a sea trial completed on the Ocean Nomad with the support of BG and Diamond Drilling, the system measured tension and inclination data over a 1-month period during the sea trial. The data was sent back to the topside system via the acoustic data link once a minute for several hours a day. The sea trial proved that the system will communicate in a range of sea states from calm to a max wave height of 7.8 m. with a significant wave height of 5.1 m.
The sea trial also proved that the Inter-M Pulse is deployable and recoverable from the back of a boat over a stern roller.
In October 2012 the Inter-M Pulse completed an ROV test at the Underwater Test Centre in Fort William, Scotland, showing the capability to replace the batteries in-situ.
The Inter-M Pulse was nominated at the 2012 ONS Innovation Awards.
