Before starting casing, the drilling supervisor should hold a pre-job safety meeting and confirm the following with the crew: 1. Remove unnecessary tools. 2. Good Housekeeping before the job 3. Rig up Casing handling equipment: Using appropriate hand. .
A circulation sub, fitting the casing thread, equipped with a WECO connection, shall be readily available on the rig floor at all times during casing running.

Break Circulation - To establish circulation of drilling fluids after a period of static conditions. Circulation may resume after a short break, such as taking a survey or making a mousehole connection, or after a prolonged interruption, such as after a round trip..

Hydrostatic pressure in drilling refers to the pressure exerted by a column of drilling mud or fluid within a wellbore. It is an essential factor in drilling operations as it balances the formation pressure and prevents well blowouts..
The load exerted on the BOP handling system by the static weight of the BOP stack. Source: API SPECIFICATION 7K, Drilling and Well Servicing Equipment, Sixth Edition, December 2015. Global Standards..
When the well is in a static condition, the bottomhole pressure is equal to the hydrostatic pressure. When the well is circulating, the bottomhole pressure increases due to the applied surface pressure needed to overcome friction pressures in the piping..
It means that the fast line tension will increase under a dynamic condition; however, the dead line tension will remain the same because it is still in static condition.
