Offshore driller Transocean has won a 13-well UK North Sea contract with ConocoPhillips.
The Swiss firm said the deal brings the estimated value of its contract backlog to around £56.6million.
It expects the work to last 580 days, starting in March 2019.
The contract also includes a one-well option.
The midwater semisubmersible rig Transocean 712 will be used to carry out the contract.
