Riser analysis is vital to your offshore-drilling company. It offers you information about the type of riser you need, the quality of your riser, and any problems you might have or be having. There are a number of different types of flexible risers, and with riser analysis, you can determine which riser will work best for you.

Stewart Technology Associates has used OrcaFlex technology to analyze risers. The software allows the company to look for critical issues and to determine solutions with all the information needed. This software is one of the most effective products in the marine technology world, and it’s used with over 170 organizations all around the world because of its quality. Stewart Technology Associates offers this technology and the ability to perform services like riser analysis, CE marking, jack up analysis, and others.

Your riser is an important part of your business. Risers are used to transport materials from the seafloor or below to your platforms at the surface, where you can then transport and use the materials. Risers often are referred to as pipelines, as they are essentially vertical pipes.

There are a number of different types of risers you can choose from¬†including attached risers, steel catenary risers, flexible risers, and others. Attached risers, for example, are often used with fixed facilities because they won’t be moved often or at all. Steel catenary risers are often considered the best value for your money, as they are flexible and can be made hundreds of meters long. They are often attached to floating platforms that may move, and they are sometimes curved to withstand more movement than other types of risers.

Pull tube risers are threaded through the center of the facility, which means that there are actually two pipes in use. The pipe on the sea floor is essentially pulled up through the secondary riser to allow the transport of fluids and gases.

Flexible risers were made to withstand vertical and horizontal movement. This means they can easily be used with floating facilities that have to move or be moved often. This is commonly used because of the ability of the risers to stand up to the changes in the ocean’s movement, and buoyancy can be changed to suit the area and needs of the particular riser.

With riser analysis, you can be certain that your riser is working correctly, so you won’t be leaking important materials or trying to work with a pipe that doesn’t want to function in the environment where you’re completing offshore drilling. Stewart Technology Associates has worked in the industry for over 20 years and can help you determine the best riser choice for your needs or work with you to analyze the risers you already have.
