Drafinsub successfully completed the J-Tube & Riser Inspection Project in Libyan waters. This project, conducted in collaboration with Saipem and Mellitah Oil & Gas, involved complex underwater inspections critical to maintaining the integrity of offshore installations, ensuring both safety and operational efficiency.
Project Overview
The J-Tube & Riser Inspection Project was carried out at the Bouri Field, one of the most significant oil and gas fields in the Mediterranean. The scope of the project included:
- Comprehensive inspection of risers and J-tubes.
- Visual inspections and Non-Destructive Testing (NDT) on critical subsea infrastructure.
- Verification of pipeline integrity and support structures.
- Detailed reporting on findings and recommendations for ongoing maintenance.
The operations were executed from the Mainport EDGE vessel, equipped with an advanced air diving spread. This vessel enabled our team to conduct the inspections with precision and efficiency while maintaining strict adherence to environmental and safety standards.

Techniques and Expertise
Drafinsub successfully executed the J-Tube and Riser Inspection Project in challenging offshore conditions. The detailed planning, meticulous execution, and cutting-edge technologies allowed for comprehensive inspection coverage while minimizing disruption to ongoing production activities.
Our team’s expertise in subsea inspection, supported by our collaboration with Saipem, ensured that all project goals were met ahead of schedule. The operations were completed safely, with zero incidents, and provided critical data to support the ongoing maintenance and operation of the field’s subsea infrastructure.
Delivering Success in Challenging Conditions
The J-Tube & Riser Inspection Project required Drafinsub to operate in the Libyan offshore environment, that presented several logistical and operational challenges. Despite these obstacles, Drafinsub’s highly skilled team worked seamlessly with our partners to ensure the project’s success. We demonstrated once again our ability to deliver world-class offshore solutions, reinforcing our reputation as a reliable partner in the oil and gas industry.
Looking Ahead
The successful completion of this project strengthens Drafinsub’s presence in Libya and highlights our capability to manage and execute complex offshore projects. We remain committed to delivering high-quality subsea solutions that ensure the integrity and longevity of critical offshore infrastructure.
Drafinsub is grateful to its partners for their collaboration and trust in our capabilities. This project underscores our dedication to operational excellence, safety, and environmental sustainability.
