Oslo-listed SeaBird Exploration has chartered out two seismic survey vessels in the Americas.

A repeat client will take the ships to provide ocean-bottom node (OBN) data.

The OBN survey should start in the first quarter of 2019, with work expected to involve three or four vessel-months.

SeaBird will be using the 81-loa Harrier Explorer (built 1979) and Osprey Explorer (built 1985) for the project.
