Weather deteriorates beyond the ASOG amber limit during a W2W operation. The gangway is connected and a technician is mid-crossing. What is the correct response?

A. Continue the transfer and assess weather again when the technician is across

B. Ask the client representative whether they want to continue before taking any action

C. Immediately disconnect the gangway regardless of the technician's position

D. Alert the gangway operator immediately; the technician should be instructed to proceed to the nearest safe platform (either WTG landing or vessel deck) as quickly as safely possible; the gangway should be retracted as soon as the technician is off it; DP operations should be reviewed against the red limit and all W2W transfers suspended

A. W2W is a helicopter transfer method for offshore wind installations

B. W2W refers to transferring crew between two vessels at sea using a gangway

C. W2W is a type of anchor mooring system used near offshore wind farms

D. W2W is the transfer of technicians from a service vessel directly onto a wind turbine generator (WTG) via a motion-compensated gangway, with the vessel holding in DP alongside the WTG transition piece — the challenge is that the vessel must hold extremely close (typically 2–5m) to a fixed structure for extended periods, with technicians physically connecting the vessel and WTG via the gangway

A. DP1 is sufficient since the turbines are fixed and the vessel only needs to maintain a general heading

B. DP3 is the minimum and DP2 is not accepted by any offshore wind operators

C. No minimum DP class applies to W2W operations — it is decided vessel by vessel

D. DP2 is the standard minimum for W2W operations — the consequence of a single failure causing a loss of position while technicians are on the gangway could be fatal (gangway shear, crush, or capsize); the redundancy of DP2 ensures a single equipment failure cannot result in loss of position
