The HPP team completed the biggest pneumatic test to date on the project. This test involves pressurising the pipes on the project with air or nitrogen to check if welds withhold the required pressure without any leaks while ensuring the system is not contaminated with water during the test. The team applied an air pressure of about 3.0 MPa (approximately 30 times the atmospheric pressure) to key parts of the piping system during this process. To put things into perspective, recreational divers – who can only dive as deep as 40m – would need to venture to a depth of about 300m to experience a similar pressure difference.
