§ 52 Cementing unit
The cementing unit shall be designed such that it mixes, stores and delivers the correct volume of cement with necessary properties to ensure proper anchoring and barrier integrity. The unit shall be designed such that residues of both unmixed chemicals and mixed cement are handled in accordance with the principles of the Pollution Control Act (in Norwegian only).
In the event the cementing unit with associated systems shall function as a replacement unit for the drilling fluid system, it shall have sufficient capacity and working pressure to be able to control the well pressure at all times.
