Overview

Mitigates vessel drift-off risk in coiled tubing operations from a vessel
Uses our midline weak link and well kill connectors as part of the intervention system
Midline weak link holds DNV Type Approval
Designed to manage loads generated by currents and vessel heave
Validated through rigorous testing, including bending under full working pressure
Supported by flexible sale or rental options, rapid delivery, and air freight ready equipment supplied in compact cases with tools and spares

In vessel-based coiled tubing applications, a controlled response to vessel drift-off is a critical part of the overall risk mitigation strategy. Our equipment is used within the intervention system to provide defined response points that support well control and help protect the vessel, the well, and connected equipment when unintended vessel movement occurs.

Application Challenges

A key challenge in this application is managing the loads applied to the coiled tubing by currents and vessel heave, particularly in dynamic offshore conditions where those forces can be transferred through the intervention system. These load effects must be managed without compromising pressure control system integrity or the wider well control philosophy, placing high demands on equipment design, qualification, and in-service performance.

How Our EQD Helps

For this application, our midline weak link and well kill connectors are used to support vessel drift-off mitigation. The midline weak link provides a controlled mechanical separation point under predefined loading conditions and holds DNV Type Approval, while the well kill connectors support the well control strategy through integration with the kill system. Together, these products form part of a robust technical solution designed to support a safer, more controlled response to unplanned vessel movement.

Key Benefits

This configuration gives operators a defined response to abnormal loading, strong confidence in structural performance under dynamic offshore conditions, and improved alignment with vessel drift-off mitigation requirements. That confidence is built on a robust design approach and a rigorous testing programme, including bending under full working pressure, to demonstrate performance against the demanding load cases associated with vessel-based coiled tubing operations.

Typical Operations

Within coiled tubing intervention spreads, these products are applied where the system design calls for a robust approach to vessel drift-off mitigation and well control integration. The focus of the application is not the specific downhole task being performed, but the need to ensure that critical equipment within the intervention package responds as intended during a loss of vessel position.

Why Choose Our EQD

Our approach to coiled tubing applications is built around engineered risk mitigation for offshore intervention systems. By supplying midline weak links and well kill connectors for vessel drift-off scenarios, and by supporting those products with robust design and rigorous qualification testing, including bending under full working pressure, we help operators implement technical solutions that are designed to perform reliably under the load conditions created by currents and vessel heave. Just as importantly, Flint Subsea makes it easy to do business with us through flexible commercial models including sale or rental, lead times as little as 12 hours, and air freight ready equipment shipped in compact wooden cases complete with tools and spares.
