Three Methods of ThemoTRON Installation

ThermoTRON® is a revolutionary high-temperature thermal insulation system that was specifically engineered to protect your pipes in the deepest, warmest waters of the Gulf. When it comes to installation, there are three methods we use. Continue reading to learn more about the ThermoTRON® installation process.


If you’re looking to protect your pipes in deep water, consider ThermoTRON® J-Lay installation. In this method, a maximum of six pipes with a total length of 72 meters are fused and upended to the seagoing pipe. The nearby vertical ramp angle is altered so that the bending of the pipe is minimized. J-lay installation is ideal for deepwater because the pipe is only bent once during installation at the seabed, and it leaves the lay system in a near-vertical position.

ThermoTRON s-lay installation


S-lay installation has been around for years, and is one of the most common forms of pipeline installation. ThermoTRON® installation via this method has proven to be extremely versatile and effective. As shown in the image to the left, Allseas performed a wet and dry S-lay tension test, and ThermoTRON® passed with flying colors. 


Rather than connecting each joint of the pipe at an offshore location like the above methods, the reel-lay method involves pre-assembling the pipeline in a spool that’s mounted on a reel barge deck.

In performing full-scale testing, we demonstrated a reel-lay application of ThermoTRON XT® at Heriot Watt University. The pipe used was 8.625 inches, its bend radius was 9 meters, and the insulation thickness was 3 inches.

ThermoTRON reel-lay installation

The image above shows another reel-lay application that was performed by TechnipFMC Spool base. This testing was performed with a field joint installed. The pipe was 8.625 inches, the bend radius was 9 meters, and the insulation thickness was 4 inches.

ThermoTRON® has been tested and proven to be the most versatile subsea thermal insulation solution on the market. At Mark Tool, we know that times are tough right now, and we’re here to help. With our protective pipeline coatings, you can rest assured knowing that your offshore structures and pipes will be protected for years to come. Contact us today to request a quote!
