Offshore installation

The installation of structures at critical stages requires reliable and accurate information with minimum equipment on-board. This reduces the duration of mobilisation and demobilisation, whilst ensuring the data collected is accurate and robust.

With our compact integrated data management service, information from multiple construction support sensors can be efficiently collated and relayed to construction assets using advanced and reliable multicast technologies. This fail-safe approach provides a reliable link to the data, removing the risk of communication loss at critical stages in the installation process.

At Ashtead Technology, we also offer laser-based positioning and attitude monitoring packages for jacket and mono-pile structures, which require no instruments to be installed, delivering even higher efficiency through the construction phase.

Ashtead Technology has the in-house expertise and knowledge to integrate advanced solutions for monitoring subsea pile foundations and sub-structure systems.

When installing subsea piled foundations, placement and depth of insertion are key considerations. It’s vital that the pile tops are aligned before the superstructure is installed. This accuracy delivers commercial advantage to our clients through reduced subsea measurement and adjustment operations.

Our portfolio includes precise remote levelling and monitoring of piles to deliver millimetric accuracy. We also provide precise remote subsea attitude monitoring systems, which are fully autonomous and fitted with high-speed integrated data communication tools to deliver precise real-time information throughout the operation.

At Ashtead Technology, we have an unprecedented track record in the safe and reliable monitoring of subsea power cable installation, and the provision of associated engineering solutions.

Utilising our in-depth expertise and project management capability, we can adapt to project specific needs, providing integrated trencher and ROV based solutions to ensure cables are inserted at the correct depth.

With advanced sensor technologies and powerful optical multiplexor data management systems, we add value through maximising cable lay performance whilst providing precise sonar, visual and electromagnetic data to accurately verify all aspects of cable installation and trenching.

The removal of natural material and preparation of the work site is often essential before any cutting or coating removal works can begin. With a range of dredge systems available from 4” to 12”, UCS engineers high-performance dredge systems to assist with the excavation of seabed sand, gravel, clay or rock.

By utilising electricity instead of hydraulics, UCS dredges offer superior suction and efficiency while eliminating the risk of harmful leakage to the environment. Our technical innovations help to improve productivity while maximising safety.

Underwater Cutting Solutions (UCS) designs and engineers an extensive array of subsea and topside cutting solutions, suitable for use on caissons, pipelines, tubulars and jackets of various sizes.

The comprehensive range of UCS cutting systems includes diamond wire and dual cut bandsaws, chop saws, hydraulic shears, and abrasive waterjet cutting systems. These can be configured for diver or ROV-deployed use, as many clients move away from traditional methods of diver installation in favour of remote operations.

UCS delivers user-friendly, high performance cutting systems which can be bespoke-engineered to your exact project requirements. International technical support and operational capability is available from highly-experienced and trained UCS technicians.
