Intervention Riser System (IRS)

IRS Integral Dual BoreOil States’ first high-pressure Merlin® intervention riser was designed and supplied in the 1990’s and is still in operation. With the design evolving, we now have 10K and 15K variants that meet NACE for 10,000-foot applications. They offer superior fatigue resistance and, because the makeup is non-rotational, hard annulus lines can be utilized.
