Insights

Transocean adds $185M of future drilling backlog across Norway and Australia.

Transocean secured two harsh environment semisubmersible contracts totaling about $185 million in firm backlog. The Norge contract with Harbour Energy in Norway contributes around $149 million over an estimated 300 days from the first quarter of 2028.

The Equinox contract with Santos in Australia adds about $36 million over roughly 90 days starting in the second quarter of 2027. Both contracts exclude mobilization and additional services, which can be incremental revenue, and include well options that could extend work but are not yet firm.

Together, these awards support utilization for two harsh environment floaters within a fleet of 27 units. Actual financial impact will depend on project execution, customer activity levels, oil and gas prices, and whether the embedded one-well options on each rig are ultimately exercised.
