Bermudian-based offshore drilling outfit Seadrill Ltd has made two senior staff appointments, and a high-profile board appointment.

The company said Grant Creed has been named chief financial officer and Leif Nelson has become chief operating officer, effective immediately.

In addition, Seadrill has appointed Svein Harald Øygard, a veteran of the government, financial and energy sectors, as a new director.

The company said Mr Creed is an experienced senior finance executive who joined Seadrill in 2013 and, prior to his appointment as chief financial officer, was chief restructuring officer leading Seadrill's capital restructuring.

During his time at Seadrill, the company said Mr Creed has held various positions including VP, Mergers & Acquisitions and VP, Corporate and Commercial Finance.

Prior to joining Seadrill, he held M&A transaction services and audit positions at Deloitte and is a chartered accountant, the company said.

Seadrill said Reid Warriner, chief operating officer, has decided to step down, adding that he “will support the company in delivering a smooth handover of activities in the coming months”.

Mr Nelson, Seadrill's current chief technology officer, will now also serve as COO, a position he has previously held.

Seadrill said Mr Øygard brings significant financial and sector expertise to the company, with decades of international experience in the government, financial and energy sectors.

He worked within the Norwegian Ministry of Finance and various other governmental agencies, including as State Secretary of Finance, where he led the work on the Norwegian Tax Reform 1992, the Norwegian Government's Long-Term Programme and the report on the economic effects of a possible EU membership.

In 1995, he joined global consultancy McKinsey in Norway, a business he ran from 2005 to 2007.

In 2009, he was interim governor of the Central Bank of Iceland, before returning to McKinsey.

He served as global knowledge leader, Oil & Gas from 2010 to 2014 and led the firm's oil and gas work in South America from 2013 to 2016.

Seadrill said Mr. Øygard has since held board positions for a range of international firms operating in the oil and gas sector and from 2017 to early 2021 worked for Sparebank 1 Markets.
