Ashtead Technology has secured a new contract with Ocean Installer AS following the successful completion of a complex subsea installation in 2019.

Ashtead Technology awarded subsea installation monitoring contract

The Aberdeen-headquartered business will provide its Deflection Monitoring System (DMS) and experienced field engineers to install six Integrated Template Structures (ITS) in the Barents Sea offshore Norway.

The DMS is a suite of structural monitoring systems to assist offshore construction operations, combining powerful software with modular technology.

The new contract has been awarded to Ashtead Technology as a result of successful completion of a similar scope last year, when nine ITS were installed in Equinor’s Askeladd and Johan Castberg fields. Ashtead Technology provided its integrated DMS equipment and services as part of the initial project, which mobilised in May 2019.

During placement of the structures underwater, the DMS systems were configured for autonomous independent operation and data communication to a nearby installation ROV.

Ross Macleod, technical director at Ashtead Technology, said: “We are very pleased to be working again with Ocean Installer in the region, building on the work we undertook in 2019.

“The harsh conditions of the Barents Sea can make data gathering challenging and time-consuming. To date, our DMS technology has allowed us to deliver all nine installations included in the first project safely and well ahead of the original completion date, reducing costs and installation time for Ocean Installer.”

Ocean Installer benefited from the robust partnership between Ashtead Technology’s offshore engineers and onshore projects group. Comprised of fully trained engineers and with decades of practical experience between them, service delivery was optimised, minimising vessel time.

Bojan Barisic, senior project surveyor at Ocean Installer AS, said: “Having used DMS equipment in the previous ITS installation process, we understand just how important a role it has played in the safe and timely delivery of our projects.

“We are confident in the level of service Ashtead Technology can offer, allowing us to complete critical operations with a high degree of redundancy within the expected accuracy range.”
