US shipbuilder Philly Shipyard has welcomed back Jeffrey Theisen as its new chief financial officer.

The Oslo-listed tanker specialist said Theisen will come in on 8 September, following the death of previous finance chief Brian Leathers last month.

Theisen was CFO between 2007 and 2015.

He was involved in the spin-off of Philly Shipyard from its parent Aker American Shipping and the subsequent listing of the company on the Oslo Axess board.
