What happened in P&A:
It was difficult to install and hold straight due to handle on the torque tool. It was also difficult to see or know if the torque tool was working in the correct manner. Time-consuming due to uncertainty of the torque tool operating correctly. We had to use low torque at the beginning to enter the connector

What Was Planned

ROV operation. Installing RIMS plate from URF to MQC on HXT

What Was Learned

When ROV is moving the RIMS plate. We need a handle for
the 5F arm on the torque tool. As it was now, the RIMS plate
was difficult to hold straight.

What Actions Are Required

Look at getting a better handle on the torque tool. Order a new tool with a counter.

What Was Done

The Rims Plate was installed correctly and with smaller problems mention the operation worked fine. But we will look into modifying the Torque tool handle or get hold of a new tool with a counter and a better handle.
