Repair & maintenance


Ashtead Technology have an extensive array of packaged solutions covering a range of repair & maintenance applications.

Whether in the form of a reactive or preventative maintenance programme, IMR tasks are an essential part of asset management. Having effective support, know-how and the ability to respond quickly with the right solutions ensures long, economical and trouble-free operations.

There is no cost-saving measure that is more important than protecting the safety of people who work to unlock vital energy resources.

At Ashtead Technology, we have a proven track record in providing a fast and effective response to a wide range of challenges, supporting offshore and marine energy production systems across the globe.

With our expertise and extensive equipment fleet, we can provide many underwater repair & maintenance tooling requirements to support asset management programmes.

Integrated solutions

The successful maintenance of offshore assets requires the correct tooling and expertise to integrate, deploy and operate equipment, and deliver a sound outcome, protecting and maximising asset life.

Our extensive tooling integration capabilities and in-house equipment based solutions can provide many maintenance and repair needs, using both ROV and diver-deployed systems.

Scouring the seabed around structures, through rough sea currents and vortex shedding can cause major issues for subsea foundations. Buried cables can also suffer from under or over-burial due to the changing shape of the seabed. The ability to accurately monitor and measure the extent of seabed disturbance and movement is a key consideration in managing assets.

At Ashtead Technology, we provide monitoring and remediation dredge systems to map the extent of erosion and offer a fleet of dredge pump systems which can be operated by ROV or diver to remediate the seabed around structures and localised cable work.

Acquiring precise dimensions for degradation, damage assessment and subsequent repair operations can be challenging, particularly underwater. Advances in subsea laser-based and photogrammetry technologies are having a significant impact on reducing time and costs.

However, these techniques have to be understood and carefully planned and deployed to extract meaningful data. This requires skilled personnel with sophisticated data processing tools to accurately process and analyse the findings.

As an early adopter of these technologies, Welaptega, an Ashtead Technology company, has an extensive track record for subsea photogrammetry delivery along with Ashtead Technology’s successful and growing track record in deploying precise laser scanning techniques. With our experience and trained personnel we can deliver a quick and reliable measurement service in real-time, ensuring the data gathered is of the highest possible quality.

A common characteristic of offshore energy production and power generation is the multitude of power cables both infield and from field-to-shore. Managing these cables requires periodic verification of the location and burial depth to ensure they are properly protected without overheating due to over-burial.

Ashtead Technology is a leading provider of seabed electromagnetic and sonar-based cable location solutions. By integrating multiple cable location systems with precise inertial position reference systems, we deliver highly precise and rapid inspections and recovery programmes, should repairs or remediation work be required.
