1. Engineering Preparation

Prior to mobilization, detailed technical data is collected and evaluated:

• Pipeline specification and material verification
• Pipe diameter and wall thickness confirmation
• Operating pressure and temperature analysis
• Flow condition evaluation
• Branch fitting and valve compatibility review
• Installation orientation assessment
• Site access and equipment clearance study

A job-specific hot tapping procedure is developed before execution.

2. Equipment Preparation

All equipment undergoes inspection and functional testing:

• Selection of appropriate tapping machine
• Cutter and pilot drill preparation
• Adapter and flange compatibility check
• Hydraulic or manual power system testing
• Pressure testing and leak verification

Only fully verified equipment is approved for field deployment.

3. Site Preparation & Safety Control

Before starting operation:

• Authorized supervisor and safety personnel present onsite
• Qualified hot tap technicians assigned
• Lifting equipment readiness confirmed
• PPE compliance enforced according to facility requirement
• Work permit and checklist authorization completed

Safety compliance is mandatory prior to operation.

4. Hot Tapping Operation

Execution sequence includes:

• Installation of full-opening hot tap valve
• Alignment and installation of tapping machine
• Nitrogen leak testing up to allowable pressure limit
• Controlled cutter engagement and penetration
• Pressure bleeding through safe direction system
• Continuous cutting until clean tapping hole achieved
• Retrieval of coupon and safe equipment removal

Once initiated, the hot tapping process continues without interruption until completion.

5. Post Operation Verification

After completion:

• Valve closure verification
• Equipment depressurization
• Environmental protection monitoring
• Coupon inspection and documentation

Operational integrity of the pipeline remains maintained throughout the process.
