Subsea Equipment Challenges

Ensuring oil and gas flow in Offshore environments, from reservoir to topside, and throughout the life of the field, is the main objective of the Flow Assurance discipline. This is not only applicable to pipelines but is also valid for Subsea Production Systems (SPS) such as xmas trees, manifolds, jumpers and spools, among others. Different FA strategies are implemented to reach such goal, being thermal management (e.g. use of insulation) one of them.

As deepwater projects become viable again, the importance of reliable insulation systems continues to be a major concern for Operators and Contractors. Deepwater subsea environments pose uniquely challenging problems. Solids deposition along cold pipe walls can easily lead to clogging and reduced flow. Stoppage points are difficult to locate, and not easily accessible once they are found. Even the least significant blockage can cause millions of dollars in potential remedial work.

As the industry pushes the boundaries of field development, Shawcor strives to offer solutions that meet the increasing demands of high temperature high pressure (HTHP) field developments.

Shawcor Solutions

Shawcor recognized the need within the market for a material which is cost effective, low risk and highly reliable in extreme environments, and have been developing and testing novel solutions for insulation specifically for the SPS field. Shawcor developed XtremeTemp CC (XTCC) to address the industry’s need for a robust solution which exhibits excellent self-adhesion properties, superior long-term performance and ductility, whilst being robust and resistant to hot and wet environments.

XTCC is a fast cure, flexible norbornene material which is extremely easy to process due to its inherently low viscosity and controlled cure profile. The material is characterized by its excellent moisture resistance and impact toughness. XTCC is also microsphere-free eliminating any unknowns of long-term syntactic foam hot/wet stability.

XTCC is specifically designed to have enough ductility to be applied to SPS and has been submitted to rigorous testing to meet ISO 12736:2014 standard for in-service conditions up to 180 °C and unlimited water depth. Due to our confidence in the materials performance at high temperature, we have now extended the test program above 200°C. In addition, its simple processing characteristics and low-pressure casting requirement, allows the mobilization of equipment to any location around the world, facilitating the application of insulation to complex structures.

It sums to our already proven materials in this sector: Nemo 2.1, which is an epoxy modified system suitable for service temperatures of 125°C and Nemo 1.1, this product is an epoxy-urethane hybrid capable of hot wet service temperatures of 95°C.

Deploying market-leading capabilities to mutually ensure project and schedule certainty at every stage.

From the Gulf of Mexico, Brazil and West Africa, to emerging areas of opportunity in India, the Mediterranean and Asia Pacific, Shawcor understands and supports the most challenging infrastructure installations. Our technologies are designed to provide reliability, flexibility and quality, while addressing the complexities of the subsea environment. Our coating systems cover a range of applications across varying pressure, temperature and water depth requirements.

Whatever your challenge, Shawcor can work with you on a custom, turnkey solution to attain and sustain the desired pipeline condition. Here are a few examples of how we are reducing uncertainty and increasing reliability in deep water projects.
