 Rebuild the lower choke valve in the sack store, lifted out and landed onto the wellhead
connector platform
 Could not retract the parking cylinder on the transporter had to lift the bop to take the
weight off the transporter before it would retract. Cleaned out the parking bolt receptacle so
see if this would help for future parking operations
 Skid the bop back to the set back are and locked in the parking bolts
 Lifted the lower choke onto the platform. Used a 5 ton chain fall which we attached to the
100 ton hoist. We came up with the 5 ton chain hoist so that the failsafe was at the correct
level then attached a 1.5 ton come along and sucked it inside the BOP
 Shut down to perform housekeeping around the subsea area.
 Back loaded the new failsafe assembly that had the wrong gasket profile
3-1/16” dual block PN:M104 SN: A28337 Body-4130 ICN: 10013631
 900 day inspection on the failsafe valves, found slight damage on the gate and seats of the
LIC. Decision made to install new gate and seats.

 Open up all bonnets. UPR. MPR and LPR
Connect a 1/2” hot-line from hotline regulated supply manifold. Using a valve and pressure
gauge trap and insure 1500 psi is kept on both locks. A hose is installed from one lock to the
other.
Slowly apply 1500 psi to open port for closing so that the nuts can be removed.
Using the Hytorc wrench (3 ¼”) remove all the bonnet nuts and install the ram extension rods
on the upper studs.

2. Vent ½” hot-line supply to open side of ram body and replace onto close side, slowly apply
pressure (500 psi max) until the bonnet is fully open. Prior to starting opening the bonnets
then ensure that the control hoses are removed from both open and close sides.
Vent ½” hot-line supply to close side of ram body and replace onto open side, slowly apply
pressure (500 psi max) until the ram block is fully retracted.
Prior to performing maintenance or inspections we vented all pressure from ram lock function
and the open and close function
 Carried out an after action review on the WRA as there were a few items that were needing
expanded on and changed slightly. Mentioned that we need to have a hose installed to both
ramlocks and also that before retracting the ram block then we cannot have the ram tray
installed as there is a potential for hanging up on the ram tray.

 Change out shuttle on open side of Upper Pipe Rams. Removed the 4 x ¾” Nuts from the front
of the shuttle. Once removed then a 3/8” allen key is used to remove the rest of the shuttle
from the body. Cleaned and inspected the sealing face on the body for the seal sub, some
slight corrosion evident.
New shuttle details
Part No. 27069-2
Serial No. G156387
 Cleaned and dressed the BSR, UPR, MPR and LPR cavities so that cavity measurements can be
taken
 Flush through the diverter with mixed stack magic from the hotline panel. A 14mm allen socket
is used to remove the plug from the flush port. Once removed a ¾” NPT Male to JIC 8 Male
adapter is installed so that a hotline can be hooked up. Flushed through for 15 mins with
approximately 200psi max. No major debris seen coming out. This done so that there is no
debris caught between the body and the drive sleeve.
 Carried out dimensional checks of the BSR, UPR and MPR

 Continued cleaning ram cavities and blocks ready for NDT inspection
 Caught up on RMS jobs

 Spool off the hotline into an open top container ready for back load
 NDT inspection carried out on all ram buttons & shear ram stud
 Closed up the following bonnets: LPR – MPR – UPR
 Started to reduce the stack accumulator N2 to 1500psi

3. Date: Friday 27th
December 2013
 Remove the bearing housing cover from the hotline reel main shaft and inspect bearing.
Bearing in good condition and moving freely. Cannot locate the new bearing, we have bearing
housings and drive sleeves but no actual bearing.
 Bled down the system. Mix tank has been emptied in preparation for cleaning
 Bring down the stack bottles pre-charge to 1500 psi. Starboard level 1 on the stack has been
reduced to 1500psi. 1 x Bottle in this bank needs increased as it is down at 1000psi (It has
been marked up)

 Put the bearing housing back together on the Hotline
 Install a new swivel on the hotline reel. Part # 3207728 ICN 100
 Found the bearing for the hotline in the store. New drive sleeve from clean workshop has been
put in the store so that we now have a complete set spare. The bearing on the port side has
been stripped down ready for change out. The starboard bearing cannot be changed out at the
moment as the disc brake is solid on the shaft and needs heat to be removed. We do not have
a spare so this is on hold until new disc arrives
 Clean out the mix tank. 2 main hatches have been removed and the inside of the tank has been
cleaned and wiped down. The tank was not too dirty anyway. Sealing rubber was damaged on
both covers, fabricated new onse and installed on the tank.
 Check the surface bottles pre-charge (1500 psi)

 Removed the Lower choke fail safes and lower down to deck in preparation for changing out
the seal seats on the LIC.
 Started to change out the oil in the HPU Pumps. Hyspin 68, 9 liters in each.
 Troubleshoot the issues with the BOP HPU mix tank (Electrical)

 Troubleshoot the issues with the BOP HPU mix tank (Electrical)
 Change out 3 x barksdale manipulator valves on the slip joint panel. 1 x valve is left in stock.
 Replace bladder from accumulator bank # 6 due to it being burst.

 Continue to pre-charge surface accumulators
 Spot check frame bolts on BOP
 Troubleshoot the issues with the BOP HPU mix tank (Electrical)
 Shut down on BOP due to overhead work on drill floor
 Complete change out of 3 x barksdale valves on the slip joint panel.

 Remove the kick out sub from the kill isolation valve to identify which profile we have on our
isolation valves. Isolation valves are “AX” and kick out sub is “AX” on bottom and “BX” on top.
 Liaise with NDT inspector to have RHT inspected. Not available until tomorrow.

Date: Friday 3rd
January 2013
 Commission the Romar Panel.
Issue with PSU 2 power supply (Loose Wire)
Issue with air solenoid valve not closing when lower packer energized. Changed out the
solenoid.
All issues have been resolved and the ROMAR package is working correctly
 Replace hose and check VLV on pump # 3 on the HPU
 Install the bottom clamp on the co-flex on the kill side until we were shut down due to
overhead PRS work.
 NDT Inspection carried out on RHT in sack store and is now ready for rebuild
 Installed the bottom clamp on the co-flex on the choke side. Still needs to be torqued up.
 Fingers have been installed on the RHT and have been lowered into the cam ring ready for
assembly.

 Installed the 4 x lifting points onto the upper annular body
 Removed the upper annular open / close shuttles from the body and placed in the clean
workshop.
 Rebuilt the RHT in the sack store and placed back into its basket
 NDT Inspection carried out on RHT in sack store and is now ready for rebuild
 Riser Adaptor, Flex joint, Upper Annular removed from LMRP

January 2013
 Welder started to work on the DMAS alterations. Hole is cut on the LMRP aft side.
 Rebuilt RHT in sack store.
 Rig up to put the new hotline reel on to the spooler. Shaft of the spooler is too large to fit
through the drum. Tried to use a 3 ½” pipe but this just bent under the weight.
 Covered the lower annular body as the mechanics were removing the 50 ton hoist above the
BOP.

5.  Cleaned inside the upper annular body
 Located the other single fail safe open isolation valve. In the forward end of the sack store

 Continued to install the new hotline hose onto the reel. The hose has been installed onto the
reel but is around 1500ft to long and the reel is full. Decision needs to be made on what they
want to do as the hose will only be 8500ft if we have to cut it.
 Rigged up to remove the LMRP from the lower BOP. Rigged up a hotline to the retract all stabs
function on the ROV panel. 1500psi was applied to the hotline. All stabs retracted but the
riser connector did not open. Rigged up a separate hotline hose to the riser connector “open”
side and the connector opened at 3400psi.

Lessons Learned
 Amended the WRA for opening and closing the bonnets. There was a potential for someone to
make a mistake if the amendment had not been made due to the fact that it did not tell you to
pressure up both sides on the ram locks which could lead to the ram lock whistle pistons
gouging out the chamber on that side
