MODU if needed, redistribute variable loads to achieve equal
leg reaction, assure that jack cylinders and jack pines are
shimmed properly, turn off electrical power to jacking
system, check anchor bolts, derrick-to-substructure and
cantilever clamp bolts, protect equipment from wind driven
rain, secure all deck equipment, cranes, and pipe, turn on
fog horn and obstruction lights, secure all water tight
doors and hatches, reduce rotary load to 100MT. |
