Maersk Drilling is letting go of around 84 workers in the United States according to Houston Business Journal.
The workers are all based on the 2013-built drillship Maersk Viking, which is coming off a long-term contract with ExxonMobil in the Gulf of Mexico.
Employees were given 60 days notice, and the layoffs are permanent unless a new contract is secured for the drillship in which case some employees may be recalled.
The rig was contracted to Exxon for three years in 2014 thought to July 2017, and later extended via an option to December 2017.
Parent company A.P. Moller–Maersk is rumoured to be in the process of selling Maersk Drilling to A.P. Møller Holding, the family investment vehicle of the Mollers.
