What additional DP monitoring requirements apply during W2W operations compared to conventional offshore DP support work?

A. W2W requires no additional monitoring beyond a standard DP close-work watch

B. W2W monitoring is the gangway operator's responsibility, not the DPO's

C. The only additional requirement is a weather watch — everything else is covered by standard DP monitoring

D. W2W requires continuous monitoring of: gangway angular position and extension relative to limits; proximity sensor distance to WTG; personnel tracking (who is on the gangway); weather trend relative to ASOG; all in addition to standard DP position/thruster/reference monitoring — and a dedicated DPO who is not distracted by other tasks during any period when the gangway is connected and personnel are on it

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
