Leak detection

Ashtead Technology has an extensive array of packaged solutions covering a range of leak detection applications.

Detecting and quantifying leaks is a necessary requirement in the overall integrity management of subsea systems as any leak has potential consequences of lost production and emissions to the environment.

We provide rapid deployment subsea leak detection solutions based on a range of techniques including advanced fluorescence, passive acoustic, sonar, hydrocarbon detection and visual techniques, and where required we can capture samples of leakage products to effectively establish the source.

Our aim is to deliver a differentiated service utilising mobile solutions and services that can rapidly and reliably detect, identify the source point and quantify the leak, delivering a reduction in cost and clear understanding of the subsea system state.

By rapidly and reliably detecting, locating and quantifying a leak any impact on production is reduced and contained to minimise the impact to the environment.

At Ashtead Technology, we provide advanced solutions deploying a range of technologies including fluorescein dye detection, passive acoustic, sonar, hydrocarbon detection and visual means to reliably detect leaks at long range from subsea equipment including pipelines, risers, connection systems, valves and manifold assemblies.

We can provide a highly effective leak detection solution that reduces inspection time and maximises probability of detection, leading to reduced loss in production and improved environmental performance.

Subsea hydraulic and chemical distribution system leaks are highly undesirable due to the cost of replacing hydraulic fluid or flow-assurance chemicals and the potential for lost production due to a control system failure. Rapid identification of the location of a subsea fluid line failure is vital to allow for remedial action to be implemented.

We provide advanced solutions deploying fluorescein dye detection systems to detect, locate and quantify subsea umbilical hydraulic line, distribution system and control equipment leaks.

With our highly sensitive long-range detection systems, umbilical fluids line damage can be quickly located and dealt with delivering reduced downtime related to subsea control umbilicals and distribution systems.

When making up and disconnecting well intervention and workover systems there is a growing requirement to verify that the BOP systems, intervention riser retainer valve and associated equipment operate as intended and do not release hydrocarbons or hydraulic fluids into the environment.

At Ashtead Technology, we provide advanced subsea hydrocarbon detection and clean-up solutions that support well intervention and workover operations.

By deploying fluorescence and visual monitoring technologies, we can validate and demonstrate compliance with specific emission regulations and deploy hydrocarbon recovery technologies if required to minimise any environmental impact.

When gas bubbles are observed emanating from the seafloor, particularly around wellheads and buried flowlines, it may not be immediately evident whether the gas has come from the production system or from natural sources. A common and reliable way of establishing the source is to acquire a sample of the gas from the seabed for analysis.

Ashtead Technology provide a rapid response subsea gas sampling service, which can be mobilised and deployed anywhere in the world. The service includes the provision of experienced personnel and equipment which can be air-transported offshore and deployed and operated either by ROV or crane-wire. With multiple easily changed sampling bottles, the system can capture gas samples, which can then be processed either offshore or in a suitable laboratory onshore.
