TCP Free Hanging Risers deliver significant cost reductions compared with the traditional Lazy wave Riser solutions used in deep water harsh condition areas such as Santos Basin Brazil.
Strohm designs and manufactures TCP Riser products for hydrocarbon production, water and gas injection, gas lift and chemicals injection. Its light weight, good fatigue performance, non-corrosiveness and spoolability make it the best solution for Deep Water Free Hanging Risers.
The solid pipe structure is impervious to corrosion, resulting in outstanding performance in H2S and CO2 corrosive environments. It has an inner, fully bonded, smooth bore polymer liner that ensures the best attainable flow properties while still being piggable. The thermal performance of TCP is considerably better than that of steel (reinforced) pipe. The dynamic performance of the Free Hanging Riser will be optimised using a weight coating layer.
Our TCP Riser is supplied in long spoolable lengths for cost-effective reel lay and lowest as-installed cost. This leads to a radical 30% saving on as-installed cost as shown in the TCP Riser business case.

Our designs and selection of materials are adapted to the specific requirements of each project, ensuring a fit-for-purpose and highly cost effective solution for each project. We manufacture TCP Risers up to 7.5 inch ID, 121 degrees C (250 F) and 10 ksi working pressure.
Storage, Transportation and Installation Reels
Risers are supplied on storage, transportation and/or installation reels, allowing deployment with a reel drive system. The reels can be offered on a purchase or rental basis.
Ancillaries & deployment
We supply our end-fittings with the following ancillaries, depending on the product and application:
No degradation due to CO2 and H2S
Very low hang-off weight. 70% reduction compared with traditional riser solutions
Superior fatigue performance compared with traditional risers
Can be deployed in cost-effective free hanging catenary configuration
40+% cost saving on total installed cost
50% less vessel days during installation
Allowing reel lay using low-spec construction vessels
Smooth bore – fully piggable
Low U-value compared with steel pipe
Spool lengths of 3,000 metres to 6,000 metres depending on diameter and pressure rating
