Buoyancy loss testing

Buoyancy testing or instrumented buoyancy loss (IBL) testing is performed within our hyperbaric chambers.

The purpose of buoyancy testing is to monitor water ingress in order to establish the effectiveness of the design and seals of assemblies and modules when subjected to extended deep water pressures. This is achieved by measuring the pre/post test weights of the products on our on-site scales, or load cells in order to confirm weight displacement. This process validates that our client’s products are fit-for-purpose prior to deployment.

Buoyancy testing is performed for a wide ranging client base including the subsea oil and gas sector, typically to support engineering, procurement and construction (EPC) and end user riser installations through compliance to API 17L or API 17U. This further extends to the defence industry to test components destined for installation on naval submarines in addition to wider marine technologies.

Tyne Pressure Testing has partnered with a number of buoyancy module manufacturers to support various testing and product validation programmes. Our nine hyperbaric pressure testing chambers provide the flexibility to suit various components in terms of both size and pressure.

Our engineers are experienced in performing buoyancy testing. We also offer the option of live remote surveillance for clients that prefer to witness testing offsite.

Sectors requiring Buoyancy Testing:

  • Oil and gas – cables, umbilical, suspension units
  • Renewables – cables and umbilical
  • Exploration – ROVs

If buoyancy testing is something that you are interested in please contact one of our experts to discuss your requirements.

What is a buoyancy test?

Put simply, a buoyancy test checks if a product is likely to float in fluid. This type of testing is done in one of our hyperbaric chambers to establish the effectiveness of the design and seals of a product when subjected to deep water pressures.

Buoyancy testing is a popular type of test for clients in the subsea and oil and gas sectors.

Will my product fit in your chambers?

Our hyperbaric chambers can fit products up to a length of 6.75 metres and a diameter of 2.50 metres.

Why choose us?

Facilities on-site

Opt for either an all-encompassing, fully project managed testing service provided by our experts and in-house engineering team, or, hire our pressure testing facilities to conduct independent testing.

Client Facilities

Our clients travel across the globe to utilise our pressure testing services and hyperbaric testing equipment. We will aim to support your connectivity to provide a comfortable working environment whilst you oversee product testing.

Whilst your product is undergoing the testing process, take advantage of our dedicated client offices, break-out area, Wi-Fi and conferencing facilities. If a client representative cannot travel to our facility, they can remotely log onto our IT system to stream live test data and video footage of their component being tested.

Reduced Lead Times

Working to a tight timescale? We can conduct 24 hour testing at our facility, subject to availability. Clients also have the option to complete testing in multiple chambers.

Our largest chamber, hyperbaric chamber TPT 5, is equipped with automated controls and an interactive system to improve efficiency and reduce loading times meaning this chamber can fill, load and pressurise in just 90 minutes!

Data Reporting

As standard, our clients receive full documentation and product certification after the testing is completed.

The majority of our hyperbaric chambers are fitted with subsea cameras and this video footage can be shared upon request.

Additional Client Services

We can offer additional services to help fulfil project requirements such as; assembly, data reporting, third party verification, logistics and storage and dedicated client facilities.

Third Party Verification

We can arrange for a third party witness to oversee your product testing and verification. We frequently work with leading authorities such as Bureau Veritas and Lloyd’s Register.
