SUMMARY

1.1. Introduction

2. The FPSO ‘Haewene Brim’ had been sheltering from the weather in the Moray Firth

waiting to connect to a Submerged Turret Production (STP) buoy at the Pierce Oil Field.

The tow began at 14:50 hours on the 7th Dec 2013 in position 57* 53’N 003* 25’W total

distance 168 nm with the tow Tug on 600m tow line length and 70 tons pull. The main Tow

vessel was the AHT DP2 ‘’BB Troll’’ which had a continuous Bollard Pull of 165 tons and

the AHT Normand Neptun as the Escort Tug. The Tow was on location at 11:40 hours on

the 8th of December 2013 in position 57* 9.5’N 002* 17.5’ E average speed 8 knots.

3. Vessel was again waiting on weather and the arrival of two small tugs. The tugs arrived at

06:00 hours on the Monday 9th Dec 2013. At 14:50 the Belly Line from the STP room was

transferred to the Stand By boats FRC and passed back to the FPSO. The other two small

tugs were then connected to the Starboard side of the FPSO one forward and one aft. The

FPSO was then towed by the BB Troll to a position 3 miles from the buoy and began

waiting for daylight. At 09:15 hours on Tuesday 10th the Grampian Pride launched its FRC.

4. Work Observed: The FRC was unable to pull the rope from the FPSO towards the buoy

and returned to the Grampian Pride. The FPSO managed to grapple the buoy rope and

connect it to the STP rope. At 12:50 the buoy was in the locked position and clamped into

the hull. At 15:35 all vessels were disconnected except the ‘BB Troll’ which had trouble

disconnecting. Eventually it was disconnected however the FPSO’s tow line could not be

recovered to the bow. The ‘’BB Troll’’ then moved to the stern and again there was a

problem with the hydraulics on the after winch. At 19:40 the BB Troll was connected and at

20:00 heading control of the FPSO began.

5. Observations: The FPSO towed easily, 10 knots at times. The stand by boats FRC had a

difficult job connecting the Belly rope to the buoy rope. The seas hitting against the FPSO

sides caused it problems. The FPSO had to grapple for the buoy rope.

5.1. Conclusions: The FRC procedures should be reviewed. The forward and after

mooring winches need attention.

This report is prepared in good faith without prejudice to any or all parties concerned.
