Riser-based operations

Riser-based operations

When you need to reach deep or where vertical access is an issue, our riser-based services have you covered.

With our riser-based operations, you have the high-pressure conduit you need.

Whether it’s for well enhancement, workover or abandonment operations, we can support you.

You can avoid the high cost and operations time involved in using a drilling rig for coiled tubing. Because we can do it for you, rigless.

With our tried, tested and trusted Intervention Riser System (IRS), we provide a direct connection from our vessel to your tree. With fast, reliable MUX control, we’re always in full control.

Once connected, our IRS provides 7-3/8” through-bore diameter access. That means you can choose between coiled tubing, electric-line and slick line services – everything you need for all your tooling needs.

We can run riser-based operations from nearly all of our vessels, including our semi-submersibles, the Q4000, Q5000, Q7000, and our monohulls, including the Well Enhancer, Siem Helix 1 and Siem Helix 2.

So, all your well enhancement, workover and abandonment requirements are covered, globally.
