Sub-Task #1 Preparation

1.1 Perform Toolbox talk
Check for a valid permit and review the required safety measures

Attached TRA M-00011431
1.2 Perform Radio communication check with ISV
1.3 Lift tools from ISV to EWP
Perform dropped object sweep, if found select "At Risk".
Report potential dropped object via HOC card to the vessel.
1.4 Check that accessories of the splice box and all material needed for the splicing are available. Check that all tools required for the work is available and in good condition.

Sub-Task #2 FO Cable Routing & Termination

2.1 Route the submarine fiber optical cable to the splice box’s location to mark the bushing position on the cable.
The FO splice box will be installed on the inner side of the cable racking above the hang-off, the box can be installed on either side, this being dependent upon which cable is pulled in first.
2.2 Refer to the FO cable routing sketch for more clarifications, NS2244-SKT-0035 [attachment-5]
2.3 Record the batch number and the meter length marking as embossed on the TKF Fibre Cables.
2.4 FO-Cables shall be guided below the interlink beam of the racking to have them protected from the stored power cores.
2.5 Create a service loop of the submarine FOC near the FO splice box
No service loop is necessary for the far reach submarine FOC.
2.6 Make sure that the FOC MBR is not breached!
TKF FOC
Diameter of the service loop has to be at least 1.9 meters.
MBR: 300 mm

PPL FOC
Diameter of the service loop has to be at least 1.9 meters.
MBR: 300 mm
2.7 Measure and record the diameter of the maintenance loops.
2.8 Fix the cable to the structure with two cable ties forming an X at least every meter over the cable.
2.9 Photographs including date/time stamp shall be taken showing the routed cable.
2.10 Get the splice box and place it on a table to have a convenient work place.

PPL two door FO Box
2.11 Install the pre-manufactured adaptor identification labels to the TKF cabinet as per the Splice Plan.
2.12 Ensure the adaptor labelling within the Prysmian patch panel have been pre-installed.
2.13 Add 2.5 meters to the mark of the bushing location, if there is any excess cable, extend the maintenance loop or lose the excess in the cable route
*Do not cut the fibre cable*.
2.14 Pull the bushing assembly over the cable, feed the cable through the box and strip the outer sheath, the stainless-steel tube to access the fibres. Follow the instruction manual of the splice box for the required lengths.
2.15 For TKF FOC, follow the FO Splice box installation manual
TKF: Fibre Box Installation Manual - Doc. No. 34014-IIN-OF0260994
2.16 For PPL FOC, follow the FO Splice box installation manual
Prysmian: Fibre Box Installation Manual - Doc. No. PPL18301-SE-PRO-005
2.17 Assemble the cable bushing and the earthing kit according to the splice box manual. Coil the spare fibre length in the splice cassette. Make sure that at any sharp edges the fibers are protected
2.18 Photographs including date/time stamp shall be taken showing the earthing of the fibre optic cable steel tube.
2.19 Clean and separate the fibres, care should be taken while carrying out this task.
2.20 Start to splice the fibres according to SOC fibre Optic Cable Splicing Instruction GEN-SUP-0707 and the splice plan.
All splices are to be installed with a splice protector.
Arrange the completed fibers in the splice cassette.

2.21 Photographs including date/time stamp shall be taken showing every splice cassette.
2.22 Photographs including date/time stamp shall be taken showing the complete FO splice box with the bushings visible.
2.23 Close the splice box and install it to the structure according to the splice box manual
Prysmian FO Box
2.19
2.24 The smaller TKF splice box should to the right side of the racking to get the FO Cable straight into the box maintaining the FO-Cable MBR
2.25 Reroute and fix the service loop (if applicable) close to splice box
2.26 Photographs including date/time stamp shall be taken showing the finally installed splice box.
2.27 Route and connect the earthing cable to the nearest earthing point on the structure.
2.28 Photographs including date/time stamp shall be taken showing the splice box external earthing.
2.29 Attach the cable identification label to the fibre optic cable above the hang off.
2.30 Photographs including date/time stamp shall be taken showing the cable identification label installed in Step 2.29.
2.31 Attach the cable identification label to the fibre optic cable just below the fibre optic box.
2.32 Photographs including date/time stamp shall be taken showing the cable identification label installed in Step 2.31.
2.33 Following post-termination testing install the patch leads interconnecting the incoming subsea cable with the outgoing subsea cable as detailed in the Splice Plan.
2.34 Photographs including date/time stamp shall be taken showing the patch leads installed in Step 2.33.
