Norwegian bond trustee Nordic Trustee is forcing through a sale of two Boa SBL seismic survey vessels.

It said that it had considered it necessary to use a stock accession option to hand control of the Boa Offshore subsidiary to bondholders to complete the disposal of the 80-loa Boa Galatea (built 2008) and Boa Thalassa (built 2009) to compatriot SeaBird Exploration.
