DP holds the line while the thruster has authority. Past ~1.5 kn cross-set the thruster saturates and the current wins. With swell running, the heave compensator keeps the draghead planted — switch it off (or push the swell past its stroke) and contact/output drop while gear stress spikes.

Suction-pipe angle sets draghead depth & reach. Hull heel/trim respond to swell and hopper loading. Zero/tare sets the current hull attitude as the datum.

Echosounder trace — newer readings at right; depth 0–14 m; dashed red = shoal alarm. Anemometer bearings are relative to vessel/dredge-line heading. VHF traffic is simulation-generated — GPS dropout and gear stress alarms trigger dedicated radio calls.
