Subsea Oil and Gas

A leading custom manufacturer of subsea seals

DP Seals works closely with some of the leading global cable connector manufacturers to develop custom subsea seals and mouldings. Our specialist manufacturing unit is dedicated to the industry and our production team is fully experienced in the demanding processes required.

We develop and supply a wide range of components to the most successful oil and gas companies in the UK, Scandinavia and further afield. D G O’Brien, Siemens, SEACON (TE) and GE Oil & Gas are amongst those prestigious companies that rely on our expertise, knowledge and experience.

Specialists in rubber cable glands for connectors

Our gaskets, seals and mouldings are often used for wet-mate, dry-mate, fibre-optic, hybrid signal, power and data cable connectors. This includes use in sub-sea applications such as:

  • Sonar
  • Surveillance
  • Real-time video systems
  • Down-hole data logging equipment
  • Oil and gas exploration
  • ROV
  • Classic telecommunications networks and other oceanography applications

Subsea seals expertise built on years of experience

Our reputation as a world leader in this field is built on 25 years experience with the subsea industry. This has driven our materials research into areas such as:

  • Low-temperature FFKM components
  • Rubber-to-rubber bonding
  • Overmoulding multi-layer components from highly conductive carbon nanotube grades combined with highly insulative silicones .

Material selection is key to performance and we work diligently to develop exactly the right blend for your application. This includes expertise in:

  • Nitriles
  • Silicones
  • High-performance Viton Extreme
  • FFKM
  • Cutting edge polymers like silicone perfluoroelastomers
  • Nanotech rubbers.

Quality assured custom rubber mouldings

Quality runs throughout our processes demonstrated by our rigorous AS 9100 quality regimen incorporating ISO 9001. We know how important it is that you can rely on components to function effectively in incredibly hostile environments. So to give you an unequivocal assurance of quality, performance and durability, we work to the NORSOK M-710 standard.

Originally developed by the Norwegian petroleum industry, the M-710 standard means that materials must achieve accepted criteria for both rapid gas decompression (RGD) – also known as explosive decompression (ED) – and sour gas ageing (H2S). Both of these are proven indicators of long-term performance and viable life expectancy.

RGD testing establishes a material’s resistance to blistering and cracking when sudden changes in pressure and temperature occur. With conformation to M-710 this proves structural resilience and seal integrity in hostile subsea applications.

Sour gas testing analyses potential degradation over extended periods of time. This includes assessing criteria such as tensile strength, swelling, elongation and hardness to ensure constant, predictable performance far beyond the likely practical life of any particular component.

In working to this standard, although materials can be approved in five different grades, we’re one of the few manufacturers to exclusively use the top two grades alone. This guarantees the highest possible levels of quality and a greatly reduced margin of error where performance criteria are concerned.
