PRE DIVE PLANNING SEQUENCE TM
Oceanic strongly recommends that you review the
Pre Dive Planning Sequence (PDPS) prior to every
dive to help you plan your dive as required to
avoid exceeding no decompression or oxygen
exposure limits.
This is especially important for repetitive dives when the
PDPS indicates adjusted dive times that are available for the
next dive, based on residual nitrogen or oxygen accumula-
tion (whichever is in control) following the last dive and
surface interval.
The PDPS provides a sequence of theoretical dive times
available for depths ranging from 30 feet (9 meters) to 190
feet (57 meters) in 10 foot (3 meter) increments.
During the sequence, no decompression times are only
displayed for depths where there is at least 1 minute of
theoretical dive time available at the depth, taking into
account a descent and ascent rates of 60 feet (18 meters)
per minute.
