From gaining understanding of the scope through project completion, hot tapping and line isolations on critical systems should be handled as a joint venture, not a transaction.
Best practice for safe execution begins with data acquisition. It is imperative that a complete understanding of all characteristics of the carrier pipe and the desired outcome of the project are understood. This information supports fitting design and manufacturing, and development of the in-service weld procedures.
From there, development of the field execution procedures and a thoruogh risk assessment can be carried out. Assessment of the equipment inspection and maintenance programs, including documentation, along with technician training and certification processes then set the standard to ensure the utmost in safety and quality.
