According to the company, the yard contract price is less than $180m.
The rigs are expected to be delivered during the first and third quarters of 2016, respectively. A Chinese shipyard will carry out the construction.
Northern Offshore president and chief executive officer Gary Casswell said the demand for jackup rigs will continue with the technical specifications and capabilities of the new assets, which are suited for marketplaces in South East Asia, the Middle East, West Africa and Latin America.
"This is a turning point for our company, as we continue to execute our stated corporate strategy of transitioning into the ownership and operation of new, state-of-the-art jackup rigs," Casswell added.
Northern Offshore operates offshore oil and gas drilling units and one production vessel in various markets globally.
