NEMO Captains Underwater Integrity
Bredero Shaw Offers Custom Coating for High-Temperature Subsea Operations
Bredero Shaw, the largest division of ShawCor Ltd., has developed a new custom coating product designed to be used for subsea pipeline components and equipment used in high-temperature, high-pressure situations.
The new product — nicknamed NEMO, which stands for Network Epoxy Modified Olefin — answers the need for a coating material to be used on irregularly shaped parts of subsea production systems, such as bends, spools, terminations (PLETS), jumpers and goosenecks.
The NEMO product family includes NEMO 1.1 and NEMO 2.1 and has been successfully tested on applications up to 120 degrees Celsius, or 248 degrees Fahrenheit. (Tests are ongoing for 130 C and 140 C.) NEMO 1.1 is an epoxy-urethane hybrid suitable for low-pressure casting applications. It overcomes the problems associated with traditional polyurethane (PU) systems, and can be used up to a maximum continuous operating temperature of 95 C. NEMO 2.1 also has speed and demold times similar to PU and can handle continuous operation up to 120 C.
NEMO is a significant addition to Bredero Shaw’s Complete Coating Assurance model, an exclusive model of integrated services for offshore pipeline coating. All three types of subsea flow assurance coatings, including line pipe, field joint and custom coating, are now available for use from wellhead to platform.
Complete and Assured
The Complete Coating Assurance model, which Bredero Shaw introduced in March, is an offshore pipeline coating model that ensures successful performance throughout the project. Addressing every stage of a project’s lifecycle from concept and pre-FEED to commissioning, the model offers complete control over the six elements that result in fully integrated coating interfaces throughout the project installation.
Reliable thermal performance starts with the first element in Complete Coating Assurance: Engineering Services. Bredero Shaw’s team of experts is adept at developing thermal insulation and corrosion protection systems that implement both insulation and heating. They take into account important project factors such as pipe handling, pipeline fabrication, field jointing and pipeline deployment and operation. All of this work is done up front to add a high level of predictability to the project.
Committed to research and development and testing, Bredero Shaw seeks to continuously innovate new solutions to solve customers’ challenges. With input from major oil and gas companies, engineering firms and contractors, the R&D team works on small to large-scale innovations in everything from materials development qualification to application development to system testing and verification.
At state-of-the-art centers in Canada and Norway, the team tests material science capabilities and develops new concepts for coatings, moldings, and casting. In these facilities, ideas can make the transition quickly from the lab to the real world through rapid scale-up and testing. Bredero Shaw holds more than 100 patents covering new products and process techniques.
Experienced research scientists and quality control personnel also work to ensure that all standards are met. Often with new products no specification exists, so the R&D team collaborates with customers to develop the needed documentation to facilitate the production and verification of new products and processes.
With six key elements, including Engineering Services, Pipe and Joint Coating Design, Coating System Validation, Logistics Management, Pipe Coating Application and Field Joint Coating, Complete Coating Assurance is today’s model for offshore success. Its prime purpose is to reduce project risk, schedule risk, and performance risk. In a fully integrated program, Bredero Shaw’s Complete Coating Assurance model meets that goal.
