Shipmasters must ensure that the mooring system is adequate and in good condition at all times at launch and throughout the supply period.
Each vessel must ensure that at least three crew members are used for mooring operations.

When delivering or receiving materials to a rig/barge in shallow waters 10 meters deep or less, a Cargo Operations Regulation will be developed in the minutes of the rig relocation meeting, a copy of which will be provided to the rig to provide clear instructions for the rig/supply visit (work of the vessel master). )
All rigs/barges provided berths will be inspected periodically by rig personnel. Any vessel noted to have mooring equipment deficiencies will be guaranteed that they will be corrected immediately. A rig/barge that is berthed with deficiencies will be reported to the rig/barge coordinators and entered into the deck log. In addition, all vessel masters are required to report rig/barge mooring deficiencies directly to the supply vessel coordinators
Under no circumstances should two vessels be operating simultaneously on the same side of a rig.
This applies to vessels firmly tied to the rig, vessels engaged in capture operations, and vessels operating in the DP or any combination of these three operations. For example, a ship cannot quickly move to another ship, and two ships cannot simultaneously work on the DP on one side of the drilling rig (the work of the ship’s captain)
Clear instructions to the Officer of the Watch (OOW) regarding actions to be taken in the event of worsening weather conditions and/or loss of position. The watch handover should detail to the oncoming traffic vessel data, cargo operations, and preliminary and forecast environmental conditions. The master or officer of the watch must notify the rig if weather conditions worsen so that the rig can prepare to free the vessel if necessary
Vessels may only remain at rig/barge berths during supply operations. If operations are suspended or terminated, the vessel must undock and proceed to the location designated by the drilling service/logistics or to the next supply location (ship master's job)
Whenever more than 45% of thruster or main engine power is required to maintain a capture position adjacent to an offshore installation, the vessel must move away and not return until conditions are safe to resume operation
