Seadrill said it plans to make more than 100 redundancies from its Houston office.
The company said the move will take place from the beginning of next month.
The announcement was revealed in a notice to the Texas Workforce Commission earlier this month.
The redundancies will target employees in the support operation of the West Capricorn, a mobile offshore drilling unit located offshore Gulf of Mexico.
The West Capricorn rig is currently under contract with BP with the oil major recently announcing plans to extend its standby period for services on the rig.
Bill Traylor, Seadrill’s director of human resources described BP’s decision as “sudden, unexpected and outside of Seadrill’s control.”
