Exhibit 99.1

SDLP – Amended Term Loan B Credit Agreement

London, United Kingdom, February 12, 2018 - Seadrill Partners LLC (“SDLP” or “the Company”) announces that it has filed a 6-K containing an amended Term Loan B (“TLB”) credit agreement reflecting an agreement reached with a required majority of TLB lenders to waive the leverage covenant until the maturity of the TLB in February 2021.

In connection with entering into the amended TLB credit agreement, we have agreed to several terms, including but not limited to, increasing the applicable margin by 3%, a prepayment contingent on the successful outcome of ongoing litigation, contributing the West Vencedor to the TLB collateral group and certain amendments relating to cash movements outside the TLB collateral group.

The required majority of TLB lenders representing greater than 50% of TLB amounts outstanding has been reached and documentation is agreed. This agreement is binding on the TLB lenders (subject to certain conditions subsequent) and will become effective with respect to the Company after receiving consent from secured lending banks representing greater than 66 2/3% of amounts outstanding in each of the Company’s three secured bank facilities and after satisfying typical closing conditions.

The secured lending bank credit approval process is well advanced and we expect it to conclude in the coming weeks.
