GENERAL
This work package contains the procedures to fully set up the TWPS for initial operation under cold
weather conditions. "Cold weather conditions" is loosely defined as when icing could be encountered in
the next 24 hours. A more precise definition of "cold weather conditions" takes into account both water
and air temperatures. Table 1 provides a general guideline that can be followed to determine when it
may be appropriate to set up the TWPS for cold weather conditions and deploy the cold weather kit.
