The two unnamed drillships, based on Sembcorp Marine’s proprietary Jurong Espadon 3T design, are now scheduled to be delivered in the first and third quarters of 2020 — roughly six months later than previously expected.

Last June, Transocean said it had deferred delivery of the two rigs by two years, with new delivery dates scheduled for the second quarter of 2019 and the first quarter of 2020.
