Class 1-4 Electrical Torque tool system with Inductive Subsea USB Connector.
The combination of the Blue Logic electrical Torque Tool (ELTT) and the
inductive Subsea USB connector interface is a very compact, flexible
ROV friendly torque tool system ideal for all types of AUV and ROV
operations. The Subsea USB connector allows for easy "hot" subsea
change out and replacement of the tool with full power.
The Subsea USB connector ensures that the torque tool has ideal
working conditions with regards to voltage and current. The tool is given
a stable 325VDC converted fromthe input voltage from the ROV.
The ROV must be equipped with a male USB connector (primary side)
(typical Blue Logic Art no. BA7713) and a separate Power Supply (BA7719).
The Blue Logic Class 1-4 Electrical Torque Tool (ELTT) is module based,
compact, flexible, robust with high precicion. The system combines the
advantages from a hydraulic torque tool system with the technology
and advantages available from a modern servo based electrical
controlled drive system. Interface sockets are replaceable on deck prior
to deployment to interface ISO Class 1-4 interfaces. The different
sockets will automatically interface the gear system to utilise the optimal
gear ratio and power/speed capacity. The control system automatically
detects socket and gear ratio and will automatically switch between
Low torque and High torque mode. The ELTT is designed for operation
on ROV's with minimum 5A 110VAC of continuous power available. Max
allowed power consumption can be limited in the ELTT control system
setup. Max continuous current consumption is 20A. The tool
communicates through RS232 protocol. The ELTT is connected to the
ROV through a 3,5 mtr. oil filled yellow umbilical connected to an
electrical power supply module mounted on the ROV
