Times may be adjusted during extreme tide conditions or to accommodate extended or night operations. Adjustments must be approved by the captain, and are published in the cruise plan. We realize that at times it makes good sense to transit at night in order to achieve station at remote locations for normal day operations. The chief scientist may request to depart prior to 0700 to reach a dive location in the morning of the first day. Departures late on mobilization days to achieve normal day operations after long transits may be requested, but the courtesy of reasonably early returns will be appreciated in return.
Early departures are dependent on crew availability and are at the master's discretion.
These lengthened days are configured as 12 hour day operations, typically associated with approximately 2 hours of transit time to the dive site. These extra hours assure that the ROV will be afforded a reasonable amount of working time at these distant sites. These extended days need to be assigned to specific dates in the calendar year. Departure and arrival times for extended days are typically set by safety, weather, personnel, and transit time considerations. A standard extended cruise without daylight restrictions will be scheduled for departure at 0600 and returning by 1730.
