CHAPTER IV
MOVING AND JACKING PROCEDURES
GENERAL INSTRUCTIONS
Independent-leg units and mat-type \mits
are designed to withstand certain operating
limits for (1) load capacities (2) afloat condi­ (1) Toolpusher
tions and (3) elevated conditions. Any attempt
to exceed these limits will jeopardize the
safety of the crew and the unit. Jacking and
moving procedures must take into account the
capabilities of the unit when sitting on bot­
tom, when afloat, or under tow. All personnel
operating the unit's equipment should read
the "Information and Operating Instruction
Book" published by the manufacturer. This
book gives specific instruction on the opera­
tion and maintenance of the tmit's machinery.
Newly classed ABS jack up rigs all have
emergency power sources. It is important to
check the emergency power plant and all
emergency systems at least once a week.
Emergency repair supplies should be aboard
the vessel at all times, and should be inspected
periodically for quantity and condition.
