Service Exchange Programme

NOV Hydra Rig’s UK Service Exchange Programme

NOV Hydra Rig’s United Kingdom facility operates a service exchange program on a range of cryogenic components providing customers with a simple, cost effective solution to cryogenic component maintenance problems.

NOV Hydra Rig provides this service exchange program from specifically chosen, strategic geographical locations around the world; these locations currently being the UK to service both the UK and Europe and Dubai to service the Middle East and in the Far East.


Cryogenic Assembly Service Exchange Component Range

This service is not just dedicated to Hydra Rig cryogenics, we also offer a range of interchangeable components common to the other major cryogenic component manufacturers. For example ACD, Cryomec and CS&P.

As far as possible, the service exchange components stocked at each location will be tailored to best suit the needs of the region to provide inventory levels to ensure components are readily available at all times.

A sample of our available cryogenic assembly components that could be part of a regional service exchange program, and their codes, are listed beside.

Please read our brochures for further informations.


The Hydra Rig service exchange programme is designed to provide the user with replacement cryogenic components without the need to increase local inventory. We will stock the most common components that have been fully rebuilt to as new condition & the rebuilt components come with a 3 month conditional warranty.

This service will now be available for the Asia Pacific region & based in the Cryogenic Tank Services (CTS) facility just outside Kuala Lumpur in Selangor D.E.

How it Works

The customer places a request for the components from CTS & they will advise the price and availability. The client places an order for the amount quoted and collects from CTS or requests CTS to ship to the client location (this would incur additional costs for shipping, possible duties etc). Once the parts are received, the client then returns the used service exchange components to CTS for re-stock & the process can begin again.

Terms and Conditions

The quoted price and delivery quoted are based on the following conditions. Failure to comply with these terms and conditions will result in the customer being invoiced in full new price of the component provided, less the cost as per the provided purchase order.

  1. The returned component must be complete: The item can be dis-assembled but must have all of the components present (excluding seals and gaskets).
  2. The returned item(s) must be returned to CTS Malaysia within 1 month of receiving the service exchange component.
  3. The returned component must be the same type as the component supplied.
  4. The returned component must be returned in the shipping box/crate in which the service exchange item was supplied.
  5. The return shipping will be door to door and is the responsibility of the customer, any costs, including freight and custom and duty charges will be recharged.
  6. Before returning a component, please contact CTS for pre-advice, shipping address and instructions.
