A subsidiary of Danish conglomerate Moller-Maersk will carry out drilling work on fields offshore Ghana as part of a four-year deal with Tullow.
Maersk Drilling said the agreement covered development drilling on the Jubilee and Ten fields.
Its Venturer drillship will start work on the contract in February 2018.
Lars Ostergaard, chief commercial officer of Maersk Drilling, said: “I am very pleased that Maersk Drilling will be mobilising another deepwater rig for this significant job in a strategically important region.
“It is our first contract with Tullow Ghana and it is a testament to our successful operational track record in Ghana. We are firmly committed to supporting Tullow Ghana’s business through safe and efficient drilling operations.
“After more than 2.5 years of operation in Ghana with Maersk Voyager, Maersk Drilling now operates with over 50 percent local staff and a wide network of local suppliers.
“We are very proud to work in Ghana and appreciate the opportunity to make use of the ever increasing capabilities within the Ghanaian indigenous sector.”
