Hi,
Currently running Repair Turret 0.5.5, Factorio v1.0.
When the repair turret picks up the offshore pump to store it into the Logistical Network, it seems to leave the connecting pipe sprite for the pump as can be seen in the image below:

I am using Space Exploration, I have not yet tested this with just the Repair Turret mod installed - but thought it was worth a mention.
