Tritorc secured a challenging offshore hot tapping project from one of the largest MNCs in the world through a strategic and collaborative approach. Leveraging strong industry reputation and expertise in hot tapping solutions, Tritorc engaged proactively with the client’s procurement and engineering team.

Introduction:

The hot tapping project at an offshore process platform aimed to create a new 8-inch connection on an existing 12-inch pipeline to facilitate process expansion. This execution was carried out in the 1st and 2nd week of April 2024. The need for the hot tapping project arose from the client’s requirement to expand their process capabilities while ensuring minimal disruption to ongoing operations. The platform, located in the Northern oil field in the Indian Ocean, required a reliable and efficient solution to accommodate the expansion.

Project Objectives:

The project involved meticulous planning, including site selection, safety assessments, and equipment procurement. Tritorc deployed specialized hot tapping equipment modified for H2S environments.Exposure to H2S poses significant environment and safety concerns. Given the presence of corrosive gas, Tritorc addressed environmental concerns by implementing ventilation systems, providing appropriate personal protective equipment, conducting risk assessments, monitoring H2S levels, and complying with environmental regulations. The hot tapping procedure followed industry standards and incorporated innovative techniques to ensure precision and safety.

Quality Control checks and Inspections:

1. Before the mobilization of the split tee, all non-destructive testing (NDT) tests were carried out as per the ASME Section V standards to ensure the integrity of the equipment and materials.

2. During the split tee welding process, dye penetrant testing (DPT) was conducted for root welding, and all subsequent passes underwent magnetic particle inspection (MPI) to detect any potential defects or imperfections in the welds.

3. Additionally, a function leak test was performed according to API 2201 standards before the hot tapping process to verify the integrity of the connections and to ensure there were no leaks present before proceeding further with the operation. These checks and inspections help maintain high-quality standards and ensure the safety and reliability of the equipment and operations.
