ALTERNATIVE GANGWAY INSTALLATION PROPOSAL
PROPOSAL 1: SHIFT GANGWAY LOCATION TO SOUTH (WITHOUT TUGGER UNIT)
FIGURE (1)
Comments:
Proposal (1) is to shift gangway landing point to south, eliminate the use of air tugger (significant reduction of weight).
Rigging up of gangway and tensioning of slings using 4 units of 10MT chain blocks (configuration, hooking points
based on drawing no. T7-PCSB-AIP-DWG-022-22. Suggest to replace chain block with turnbuckle once the gangway
in the position for long term at Platform M3DR-A. High tide or low tide use to be adjusted from PAP at barge. PAP
can be repositioned, secured with choke and elevation can be adjusted accordingly using scaffolding board.

OPTION 1B (WITH PADEYES):
Comments for Option 1B (with padeyes):
For both primary and secondary line requires 8.5T padeye design as anchor points. For this option require longer
lead time to supply the materials (EH36) 4 - 5 working working weeks including fabrication in Labuan. Furthermore,
the padeyes installation should include additional workscope of welding habitat, MPI and Loadtest that high
possibilities to impact cost and schedule.
