The standard turn-around time for NDSF ROV re-deployment is 12 hours. This is defined as vehicle on deck to vehicle launch. Turn around time can include re-deployment of the same vehicle, i.e., Jason, Medea, or it can include switching to another vehicle such as Alvin, Sentry,or another vehicle when NDSF personnel are involved in these other operations. NDSF shipboard personnel will always attempt to shorten this time when possible at the discretion of the Expedition Leader, and there will be many circumstances when it may be significantly shortened. However, the deployment, recovery, and operation of NDSF vehicles can be an inherently dangerous undertaking. When personnel are not rested, people are more likely to be injured or cause damage to equipment. Therefore the following will be considered for shorter turn around times:
- The primary consideration is Operations Personnel sleep and rest status. Sleep and rest of the operations personnel will not be compromised. It is acknowledged that the Ops. Team, though operating around the clock, generally attempts to get their longer sleep period between 2000 and 0800. Therefore, if a vehicle is turned around during daytime hours, defined as recovered at or after 0800 AND redeployed before 2000, then a faster turn around will be considered.
- If there are repairs to be conducted to the vehicles this will affect our ability to do a faster turn around.
- Changes to vehicle science configuration will affect our ability to do a faster turn around.
- If Ops. Personnel are concentrating their efforts on science or other equipment repairs this will affect our ability to do a faster turn around.
- Deployments of elevators also are a consideration because NDSF personnel build, deploy, and navigate the elevators to the sea floor.
- Attempts should be made to have all launches and recoveries occur at the change of watch, i.e. 0400, 0800, 1200, 1600, 2000, and 0000. This will help keep personnel on their normal sleep schedule and make it easier to do a fast turn around.
hours out of every 24 hours submerged will be designated Pilot Training Time.
Pilot Training will occur on the designated Training Pilot’s watch, after
coordinating this time with the Expedition Leader, Science Watch Leader, and
