SeaBird Exploration has posted weaker first quarter earnings in tough offshore markets.

The Oslo-listed seismic survey vessel operator said net profit was $1.8m, compared to $63.3m in the same period of 2015.

The big result last year was due to a restructuring gain of $61m, however.

Revenues rose to $26m, an increase of 7%, but EBITDA was down at $7.4m, against $8.2m the year before.
