RE: Hook up & commissioning2 Jan 2019 20:18
If you look at PMO's RNS for Catcher as an example vessel arrived 18th Oct attached buoy next day,tested turret the following day and carried on commissioning until first oil 23rd Dec, so around 9 weeks, so that should give all the interested parties a rough timeline of what to expect.
The only difference is that Catcher isn't West of Shetland.
But the weather shouldn't affect commissioning, only attaching the buoy and anchor handling.
Good luck to all holders.
