Subsea Steel Catenary Riser and Hybrid Riser Design Online Course

A Steel Catenary Riser (SCR) is a compliant riser. The name catenary simply originates from the catenary shape of the riser. Nowadays, the SCR technology has emerged as one of the top solutions for subsea field development in deepwater. SCR is known to be economically attractive in terms of both installation and construction, and compared to flexible risers they are easier and cheaper to produce in longer and larger sections. Due to the material, they also have high resistance to the internal and external pressure they are exposed to at larger depths. The steel may also be modified to different alloys for increased strength capacity. SCRs are more sensitive to dynamic motions when they are light in water (e.g. gas production/injection risers), and these risers are less resistant to fatigue.

There are two types of hybrid risers: Single Hybrid Riser and Bundled Hybrid Riser. The lower parts of the Hybrid risers are tensioned risers attached to the seabed by gravity and suction piles. Hybrid risers accommodate relative motion between a floater and the tensioned risers by connecting them with flexible pipes. The connection of the tensioned risers and the flexible pipes is done either directly using rigid gooseneck, or through fluid swivel bearing. This configuration can use disconnectable turret and decoupled risers, which means the floater can move in case of extreme weather conditions, and leave the risers subsea. Because the tensioned riser is located at depths where there is less significant wave loading, hybrid risers can cope with harsh environments.
