GC Rieber Shipping: Shearwater GeoServices awarded North Sea survey for Premier
Oil

GC Rieber Shipping ASA's 50% owned geoservices company Shearwater GeoServices
("Shearwater") has been awarded a UK North Sea high-resolution 3D project on the
Tolmount Field for Premier Oil. The survey is scheduled to start late Q2 2018
and will be executed by the Polar Duchess.

Premier Oil is a leading independent exploration and production company with oil
and gas interests in the North Sea, South East Asia, the Falkland Islands and
Latin America. The Tolmount Field, located off the coast of Yorkshire, is one of
the largest recent discoveries made in the Southern Gas Basin. The survey is
expected to take about one month and will provide high-resolution imaging of
approximately 400 sqkm of the Tolmount Field.

"This marks the return to the North Sea following last year's active season. I'm
especially pleased to see the Polar Duchess working for Premier Oil, conducting
Shearwater's first high-resolution appraisal project in the UK North Sea", said
Irene Basili, CEO of Shearwater.

Shearwater has recently won several contracts for different oil companies in
West Africa and with TGS on the Norwegian Continental Shelf, building a strong
backlog for its fleet through the fall of 2018.

Shearwater GeoServices is a marine geophysical services company jointly owned by
GC Rieber Shipping ASA and RASMUSSENGRUPPEN AS. The company has a fleet of four
modern seismic vessels, a broad offering of high quality geophysical services
including advanced software, processing and acquisition techniques, and two

industry.
