Tyne Pressure Testing partnered with a defence industry manufacturer to carry out leak testing of electronics enclosures installed on a manned underwater craft. Electronics enclosures are designed to house and protect delicate electronic equipment that would be damaged if exposed to water.

Hyperbaric testing chamber TPT 2, which has an internal diameter of 1.4m and length of 3m, was selected for the testing due to its ability to simulate pressures reflecting 1,000m below sea level. Where the electronics enclosures had glass frontages, racking was used to separate the components during test.

The electronics enclosures were initially subjected to a four hour test at pressures of 4.5 Bar, which equates to water depths of 45m, before being removed and inspected. The enclosures that passed the initial test were then subjected to a further one hour long test at 3 Bar, equating to water depths of 30m, before a final inspection.

In order to confirm that the electronics enclosures were suitable for use on a manned submarine, leak testing was required to check that the enclosures were leak-proof and would not allow the penetration of water whilst under pressure.

During inspection, it became clear that only a small number of enclosures had passed the leak testing as the majority had signs of water penetration in the sealing system. This meant that the test was classed as a failure and subsequently the sealing system was redesigned.

The testing was overseen by our experienced on-site testing engineers alongside an on-site client witness, who was later provided with a post-test document pack containing raw test data and a test record sheet.

Paul R. Smith, CEO at Tyne Pressure Testing said: “This project was a fantastic example of the importance of physical testing to fully verify product designs. Tyne Pressure Testing’s facilities and expertise allow field conditions to be simulated prior to product use in the field.”

Our nine hyperbaric chambers provide the flexibility to suit various components in terms of both size and pressure. This, along with an inherent knowledge of testing requirements and standards that span electrical, buoyancy, sensory and operational componentry bound for the underwater naval defence sector, means Tyne Pressure Testing continues to be a preferred partner for suppliers of this industry.

Tyne Pressure Testing has provided on-going, on-site hydrostatic testing and leak testing on fabricated stand pipes for Doosan Babcock.

The purpose of this testing was to verify the structural integrity of the stand pipes for use in a nuclear power station and to ensure that the components met industry standards BS EN 13480-5 and ASME B31.3.

Tyne Pressure Testing invested in various equipment to enable on-site testing including a transportable container which houses a pump, booster and data loggers. The container is fully self-sufficient, relying solely on air compressors to operate, with the structure acting as a safety barrier between the on-site engineers and the testing, allowing on-site testing in most circumstances.

The testing was carried out over several months at the Doosan Babcock facility. During testing, the stand pipes were placed within the restricted area and subjected to hydrostatic testing to varying pressure up to 261 Bar. A filtration system was employed to distil the water used ensuring that the components were not damaged by chemicals present in unfiltered water, such as chlorine. High pressure gas testing, otherwise known as leak testing, was also carried out to ensure that the pipes are leak-proof.

A Tyne Pressure Testing engineer was present on-site at Doosan Babcock daily to oversee the project from the safety of the container. Where required, night shifts minimised disruption within the facility and ensured that all tests were carried out within the client’s schedule.

Peter Holliday, Operations Manager at Doosan Babcock, said: “Tyne Pressure Testing tested multiple pipe spools which supported the successful delivery of a significant project to a major client of Doosan Babcock.”

Paul Smith, CEO at Tyne Pressure Testing, said: “All components tested have successfully passed all client and industry requirements, meaning they are suitable for use in nuclear power stations. We look forward to our continued partnership with Doosan Babcock.”

Our transportable, fully self-sufficient container and equipment means that we can facilitate on-site test sequences that satisfy qualification tests in accordance with various industry standards. Our expert engineers hold decades of experience in the execution of energy production componentry testing.




Tyne Pressure Testing has partnered with a number of buoyancy module manufacturers to support various buoyancy aid testing and product validation programmes.

Traditionally used on naval submarines, or as part of a riser system in the oil and gas industry, the modules tested on this occasion required instrumented buoyancy aid testing to confirm that they do not allow the penetration of water whilst under pressure. This type of testing ensures that the buoyancy aids are fit for purpose and will not sink whilst supporting infrastructure, once deployed.

Measuring 4.5 metres long, the modules were tested in hyperbaric testing chamber TPT 5 due to its length and fully automated loading, pressurisation and monitoring system.  Chamber 5 also has the ability to simulate ultra-deep water temperatures down to -2°C.

Each buoyancy unit was weighed before being subjected to pressure equivalent to 3,000 metres below sea level. After 24 hours of exposure, all of the units were found to weigh the same as they did before the pressure was applied, which confirmed the design, material and coating treatment were water-tight and had been completely unaffected by the pressure. As a result, our testing engineers confirmed that the units were effective buoyancy aids and therefore suitable to be installed on submarines.

The testing was overseen by our experienced on-site testing engineers; Kevin Brotherton, Jack Lowes and Angelo Addeo, with client inspection teams subsequently viewing test progress and data charts offsite. Live remote surveillance of ongoing tests can be provided for clients that prefer to witness testing offsite. This is also complemented by the provision of post-test data recordings and certification.

Our nine hyperbaric pressure testing chambers provide the flexibility to suit various components in terms of both size and pressure. This, along with an understanding of client requirements and the demands of global industry standards API 17L & API 17U, means Tyne Pressure Testing continues to be a preferred partner for engineering contractors requiring both destructive testing and non-destructive testing for subsea products.




Tyne Pressure Testing worked with BuTech, a US manufacturer, to test a series of ball valves to ensure that they could withstand the extreme pressures and temperatures of a deep sea setting.

Testing was carried out on a two-way 10K ball valve, as well as a three-way 10K ball valve to ensure that they would meet industry standards set out in API 6A/17D.

Ideal for testing small diameter ball valves, TPT Chamber 4 was used to run 200 hyperbaric cycles, with pressures reflecting water depths of 4,140m, along with 600 endurance cycles. TPT Bay 1 was also used to carry out a total of 200 environmental cycles, comprising of 160 cycles at ambient temperatures, 20 cycles at 121°C and 20 cycles at -18°C, ensuring that the ball valves met industry standard API 6A PR2.

During inspection, the data confirmed that both ball valves passed and therefore met client and industry standards. This confirms that the valves can withstand extreme pressure and temperature variations and are therefore suitable for deployment in a hostile, subsea environment.

The testing was overseen by our experienced on-site engineers and a client witness present for the critical steps of the process. The witness was provided with a post-test document pack containing raw test data, test record sheets and certification.

Scott Reib, Product Manager at BuTech, said: “The offshore oil industry requires that valves being used on critical equipment deployed to the ocean floor go through extensive testing to insure their performance.  Tyne Pressure Testing was instrumental in helping us achieve this qualification for our subsea ball valves.  Tyne Pressure Testing is one of only a hand full of companies that can perform this type of testing and their knowledge and professionalism made them our obvious choice”.

Gavin Coleman, Business Development Manager at Tyne Pressure Testing, said: “We were delighted to provide BuTech with a successful conclusion of both comprehensive test sequences to validate the product’s design robustness. With many products destined for critical service applications, we are excited to support BuTech on an array of new technology qualification programmes.”

With conventional test bays and environmental chambers, coupled with nine hyperbaric chambers on-site, we can facilitate prolonged test sequences that satisfy qualification in accordance with industry standards API 6A, 6D, 6DSS and 17D. With a workforce holding decades of experience in the execution of oil and gas production componentry testing, Tyne Pressure Testing continues to be a preferred partner for manufacturers requiring valve and actuator FAT and qualification.




Tyne Pressure Testing employees, along with employees from across the British Engines Group, came together to donate to local foodbanks across the North East as part of Christmas Jumper Day.

Newcastle East Foodbank, part of a nationwide network of food banks managed by The Trussell Trust, was chosen to receive donations. Located in Heaton, the project was founded by local churches and community groups to help stop hunger in the local area. They provide people in crisis with three days’ worth of nutritionally balanced emergency food and support.

Since March, the demand for food banks has been higher than ever due to the devastating effects of the Covid pandemic. Whether hit by redundancy, school closures or other crises, more people than ever were sadly forced to rely on foodbanks over the festive season.

A total of 258kg of food along with a further £232 was donated by Tyne Pressure Testing and employees from across the British Engines group. This equates to a total of ten, large family food parcels and excludes donations of toiletries, chocolate and children’s toys which went towards helping families provide their loved ones with small Christmas gifts.

Jodie McAndrew, Group Marketing Manager at British Engines, said: “We are very grateful to all of our employees for their kind and generous donations which we hope went some way towards helping people within the local community to have an easier and more enjoyable Christmas despite current circumstances.”

In order to go some way further towards helping those struggling in the local community, the British Engines group donated an additional £10,000 to three local food banks, including Newcastle East Foodbank, Feeding Families and Hebburn Helps.

From 2nd March 2020 Tyne Subsea will become known as Tyne Pressure Testing in order to appeal to a wider variety of industry sectors.

Since becoming fully operational last year, Tyne Subsea has had huge success in selling its services to the subsea sector; developing relationships with a range of major customers.

In addition, it continues to receive a significant number of enquiries and orders from outside the subsea sector; including aerospace, mining and nuclear.

Paul Smith, CEO at Tyne Subsea, said: “Feedback suggests that the name Tyne Subsea might mislead potential customers into thinking that the business only undertakes a certain kind of pressure testing within a particular sector.  Which is obviously very far from the truth; over the last 12 months we have been able to design a variety of testing solutions, including complex tooling requirements, for a wide range of sectors.

“Rebranding the business to Tyne Pressure Testing will reduce confusion around the services we provide and position us simply as a pressure testing specialist, to whichever sector requires it. This new branding and corporate identity enables us to market ourselves to other sectors more easily.”

Wondering how these changes might affect you?

Tyne Subsea has already begun to contact all customers and suppliers about these changes, but if you have a query about how these changes might affect you as a customer or a supplier, please do not hesitate to get in touch.


We are currently pressure testing an 18 inch Ball Valve in TSS5, the largest of our nine hyperbaric chambers.

The valve, which is 2.25 meters in both height and width, has been going through vigorous qualification testing at our facilities in Newcastle and is now undergoing hyperbaric testing at simulated water depths of 2,400 meters (34,811 psi), as well as hydrostatic testing to pressures of 6,380 psi.

Prior to the pressure testing, our engineers completed a PR2 test on the valve, which consisted of gas and temperature testing at +105˚C down to -20˚C in Environmental Test Bay 1. It is expected that it will take approximately five weeks to complete all necessary testing in order to verify that the valve can successfully operate within the extreme environments in which it will be deployed.

Once the hyperbaric testing has been completed, the valve requires endurance testing over 800 breakout cycles; which will mean that once it has finished its qualification testing, the 18 inch valve will have run a total of 1,200 breakout cycles.
