OSS - Fiber Optics Cable Routing and Termination - duplicate

1.1 Perform Toolbox talk

1.2 Perform Radio communication check with ISV

1.3 Lift tools from ISV to the Cable Deck

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.

1.5 Check that all tools required for the work is available and in good condition.

1.6 Check that FO topside cable racking (Green color) are installed before starting FOC termination.

2.1 Route the submarine fiber optical cable to the location of the splice box above the hang-off for marking the bushing position on the cable.

2.2 Create a maintenance loop measuring no more than 10m and no less than 5m whilst maintaining the minimum bend radius.

2.3 Make sure that the MBR of the fibre optical cable is not breached! MBR: 300 mm

2.4 The topside cable will be stored and coiled above every FO Splice box location. <br>Unfasten the topside cable and service loop and route it to the splice box location.<br>

2.6 Get the splice box (TELECOMBOX 240) and place it on a table to have a convenient work place.

2.7 Add 3 meters to the mark of the bushing location, the excess length can be cut off.

2.8 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.

2.10 The TKF cable design entails two FO cables, hence there is a need for two cable entrances in each FO box for HKZ1-2 (OSS Alpha)<br>- Modify the fibre Optic splice boxes on OSS Alpha<br>- Replace one blind flange with a cable gland similar to the one already installed in accordance with 54351-IIN-OF0260994

2.11 Assemble the cable bushing and the earthing kit according to the splice box manual. <br>Coil the spare fibre length in the splice cassette. <br>Make sure that at any sharp edges the fibers are protected <br>

2.12 Clean and separate the fibres, care should be taken whilst carrying out this task.

2.13 Start to splice the fibres according to SOC fibre Optic Cable Splicing Instruction GEN-SUP-0707 and the splice plan. <br>All splices are to be installed with a splice protector. <br>Arrange the completed fibers in the splice cassette. <br>

2.16 Close the splice box and install it to the structure according to the splice box manual

2.17 Reroute and fix the service loop close to splice box.<br>Fix the cable to the structure with two cable ties forming an X at least every one meter over the cable.

2.18 Connect the earthing cable to the earthing bolt

2.20 Attach the cable identification label to the fibre optic cable above the hang off.

2.21 Take photograph of the cable identification label installed above the hang off

2.22 Attach the cable identification label to the fibre optic cable just below the fibre optic box.
