Singapore’s Keppel Corp has secured a contract for a second semi-submersible drilling rig from Oslo-listed Awilco Drilling worth $425m.

The deal involves the exercising of one of three options attached to a newbuilding order for a single rig placed in March 2018.

Awilco has independent options to order up to another two similar rigs to be exercised in 2020 and 2021 respectively.
