Leg Planning
12–18 Months Precruise
With input from the Science Operator, JOIDES OPCOM developed the drillship schedule at least a year in advance
The schedule was constructed from the list of proposals approved for future ocean drilling, taking into account any priorities established by JOIDES. The Science Operator provided JOIDES OPCOM with estimates of the ship time required for each proposal, identified operational issues (both engineering and weather) and possible port calls. The ship schedule was then constructed to maximize on-site time and minimize time spent steaming between sites or to and from port. Proposals that did not require a full 2-month ODP leg were combined to maximize efficient use of ship time and to allow the Drilling Contractor to maintain a regular crew rotation.
