The recycling of the old Tyra set an industry benchmark

Recycling and reuse have been an integral part of the Tyra Redevelopment project from the start, where TotalEnergies EP Denmark and the DUC partners have set high demands for the recycling yards and envisioned sustainability in all stages of the planning process.

Specially trained personnel have methodically removed and dismantled the enormous old Tyra platforms, and as such ensured that 98.5% of the materials have either been directly reused or recycled.

The recycling of the old Tyra is the largest recycling project of offshore installations in Denmark’s history, and many processes and guidelines were built from scratch as no regulations existed in the country at the time. This contributes to a wealth of knowledge needed for future projects in the industry.

tons of steel from the old Tyra has been recycled, an equivalent of seven Eiffel Towers.

“Some parts of the old Tyra are reused in their original form. For example, a few of the generators are used again elsewhere. Other parts are processed and traded on the international market as part of the circular economy. For instance, the steel from Tyra was remelted and can be reused for new construction projects and alike.”

Tyra Redevelopment

Tyra is Denmark’s largest natural gas field and has been a center for processing and exporting more than 90% of the natural gas produced in the Danish North Sea since 1984. Due the field’s natural compaction after many years of production, the seabed below the Tyra platforms sank more than five meters. This reduction ultimately meant that a redevelopment was necessary to enable continued safe and efficient production.

In 2017, the decision was taken with the Danish Government to rebuild Tyra, presenting the largest investment ever taken in the Danish North Sea. The Tyra Redevelopment includes three main elements: decommissioning and recycling of the old Tyra platforms; modification of the six old well head and riser facilities; construction of a new process platform and a new accommodation platform.

In September 2019, the production of Tyra was suspended to enable the redevelopment. Since then, the old facilities were removed and recycled, and the new modules were constructed at yards around the world and successfully installed in the Danish North Sea.

The redevelopment is currently in its final phase, and all hands are on preparing the restart of Tyra’s production.

What is Tyra II?

The modernized Tyra II will be one of the world’s most advanced gas fields which is taking productivity, innovation, and environmental standards to new heights.

The new facilities are equipped with around 100,000 data points retrieved from sensors on critical equipment, which will continuously be monitored and analyzed by the onshore control room team. At the same time, Tyra II has a simplified infrastructure and improved energy efficiency. Thanks to new technology and ways of working, Tyra II will be able to produce gas with 30% lower CO₂ emissions compared to the former platforms.

Once fully operational, the field is expected to deliver 2.8 billion cubic meters gas per year making Denmark again a net-exporter and self-sufficient in natural gas, and as such the field will contribute to Danish and European energy security and independence.
