If the rig is situated alongside a Host rig and the Host rig is the owner and manager of the 500 m zone and is in charge of all communication with vessels entering and leaving the 500 m zone, this Operational Checklist is not applicable for the rig. Vessel Name: Displacement (t): Date: Time In: Time Out: Mode of Station Keeping: DP/Manual Rig Heading: Wind: Current: Seas: Swell: Side of rig to approach (port/stbd):
Further Risk Assessment Before Allowing Entry Yes No Comment Is the vessel’s displacement above 5000 t? If the answer is yes to any of these questions, the proposed operation should only commence if sufficient risk reducing measures are implemented. Use Technical Instruction Template for Risk Register and Risk Matrix (M-CPH -1171-02756) The Technical Instruction MD Boat Impact Guidance (M-CPH-1171-42150) can support the assessment of whether it is safe to continue. Is percentage of available thrust required to keep stationary expected to be above 45? Is the significant wave height above 4 m? Is the mean wind speed above 30 knots? Is the current above 2 knots? Risk reducing measures may include only allowing vessel operations on leeward side, limiting the allowed speed of approach, prescribing a particular angle of approach or other operational restrictions. It may also be decided to await improved weather conditions.
Risk Reducing Measures Taken:
# Vessel Status (#1-19 ref. GOMO appendix 8-A) Yes No Comment Environmental conditions acceptable for a safe operation (Including wind, sea, swell, visibility and current) Limitations due to sea/weather condition Safe approach / exit routes identified. Stand-off location identified Confirm whether any simultaneous operations anticipated whilst vessel is within safety zone Confirm whether any prohibited zones at facility Bridge and Engine room manned in accordance with GOMO Communication established VHF Channel(s): UHF Channel(s): No hot work/smoking on deck within safety zone Auto Pilot off All manoeuvring and steering gear systems tested including change over between control positions and manoeuvring modes

Emergency manoeuvring system confirmed to be operational Operating location confirmed with facility Status of over side discharges confirmed with facility Vessel to be maneuvered to set-up position before changing mode (1.5 ~ 2.5 ship’s lengths depending on whether in drift on or drift off situation) Vessel operational capability reviewed/confirmed (to include power, thrust, location, heading, etc.) Risk assessment for alongside operations reviewed/confirmed (if working on weather side, complete additional RA) Facility to confirm readiness for vessel arrival and operation (including no overboard discharge) Maneuvering mode during the operation to be agreed (if DP mode vessel specific DP checklist to be completed) On-going and/or planned activities within safety zone confirmed between facility and any other vessels Vessel seeking entry to the 500 m zone is contracted by either MD or client? Confirm that vessel is aware of any prohibited zones around the facility Planned activities and type of transfers to be confirmed between rig and vessel. Inform vessel if any simultaneous operations anticipated while vessel is within safety zone.
Abort Operation Ongoing vessel operations within the 500 m zone are to be aborted if the weather deteriorates significantly, if communications between the rig and the vessel is lost, if the vessel suffers from technical or personnel issues affecting its ability to hold station or if it for any other reason is deemed unsafe to continue. In such situations, the vessel should leave the 500 m zone until operations can safely be resumed.
Vessel Departure Checklist (500 m Zone) Departing supply boat to confirm no incident has happened while staying alongside that require any near miss reporting: If the reply is no this will be entered in to the log book If the reply is yes the Marine Section Leader (MSL)/ Deputy Offshore Installation Manager (DOIM) or Offshore Installation Manager (OIM) has to be notified. They will contact the boat to get information on incident and obtain a preliminary report.
