SeaBird Exploration has launched a private placement to fund the purchase of two of Boa SBL's seismic survey vessels, the sale of which is being forced by bondholders.

Nordic Trustee said last week it was considering a stock accession option to hand control of the Boa Offshore subsidiary to bondholders and divest the 80-metre Boa Galatea (built 2008) and Boa Thalassa (built 2009) to SeaBird.
