Located roughly 60 miles offshore Nigeria, the Erha North phase two development sits at 3,960 feet / 1,200 meters deep and is an extension of the existing Erha subsea system and infrastructure. The existing system is currently producing to the Erha floating production, storage and offloading (FPSO) vessel.
Performance at every level
Appointed by subsea engineering, construction and
services company, Subsea 7, Trelleborg was awarded
a contract to supply its high temperature thermal
insulation material for phase two of the project in YEAR.
Subsea 7 is one of the world’s leading contractors
in seabed-to-surface engineering, construction and
services to the offshore industry, providing technical
solutions to enable the delivery of complex projects
in all water depths and challenging environments.
Trelleborg supplied several tonnes of its high
temperature advanced silicone insulation solution,
Vikotherm™ S1, to the numerous oil and gas flowlines
in the field. Manufactured using room temperature
vulcanization technology, the coating is ideal for
the high 300 °F / 149 °C temperatures required
for this project.
Project specific performance Trelleborg developed a high temperature, microsphere
free product to improve overall performance of the
insulation system. This provided an added assurance that
the product has been installed properly and was fit for
purpose; verifying both the cast insulation and substrate.
The product was designed specifically to cater to
the harsh environment at the Ehra field, incorporating
a unique silicone compound. The system can operate
at ocean depths of 9,832 feet / 3,000 meters and
temperatures as high as 300 °F / 149 °C, so that
the flow of oil and gas is not compromised.
“As the offshore industry continues to get more complex, we’re more frequently searching for products which not only meet the specification, but also provide added benefits such as time saving and increased efficiency. Trelleborg’s Vikotherm™ S1 insulation was the ideal choice for the project, as it caters to the water depths and temperatures to guarantee flow assurance.” Acim Rezig, SCM Engineer at Subsea 7
