Proserv’s goal is to add value and wealth creation to operators, and support maximising economic recovery with design, manufacture, and application of subsea sampling systems, through provision of sound engineering and production chemistry practices. We ensure you get the right sample, from the right place, with the right equipment.

Representative subsea sampling

Proserv works in partnership with clients to design, build, maintain and operate a range of subsea sampling systems to allow for representative subsea sampling.

We specialise in delivering solutions for remotely operated vehicle (ROV) and diver subsea sampling systems, allowing for the capture of representative samples from the subsea tree, pipeline or manifold.

Based on market-leading sampling technology, our subsea sampling cylinder (SSC) is designed and qualified specifically for use in the harsh environments experienced subsea. In addition, the Proserv SSC is certified for shipping, under PED & DOT, therefore eliminating the risks associated with handling and transferring samples to transportation containers.

Designed to meet the stringent requirements of NACE, API-6A and API-17D, Proserv’s subsea sampling system specification can be customised as required to meet the client’s needs.

Our subsea sampling rental units are available for rapid deployment.


We provide subsea sampling solutions that support:

  • Integrity
  • Umbilical controls
  • Decommissioning
  • Chemical injection
  • Flow assurance issues
