===Dynamic positioning alarm and runout response for bell divers===
*Code amber /Yellow alert – Divers return to the bell immediately, stow umbilicals, and stand by for further developments and instructions.<ref name="IMCA D022 2016 11.8" />
*Code red – Divers return to the bell without delaying to retrieve tools and prepare for immediate ascent. The bell can not be recovered until the umbilicals have been safely stowed.<ref name="IMCA D022 2016 11.8" />
The basic response with a closed bell is similar to wet bell, but after stowing umbilicals, the hatch will be sealed so that internal pressure can be retained. The bell will be recovered as rapidly as possible in a red alert, and may be recovered if there is doubt that a yellow alert will be downgraded.<ref name="IMCA D022 2016 13.10" />
