Our History

Shearwater GeoServices was established by GC Rieber Shipping, with supporting investment from Rasmussengruppen powered by an experienced team of industry professionals. Shearwater GeoServices is an integrated provider of geophysical services and seismic software solutions.


GC Rieber

Since being founded in 1879 as a Norwegian business trading skins and leather, GC Rieber has evolved over four generations to a global shipping organization providing ship development, design, construction and operation services to the subsea, seismic and ice/support sectors. 

GC Rieber is not new to marine seismic having performed pioneering operations in the Hudson Bay and Canadian Artic as early as the 1960s.

In 1936 the first company in the group was established by the then ship-owner Einar Rasmussen.

After World War II the group built itself into a substantial business of international shipping. In addition to conventional tankers and bulk shipping, the business became focused on developing niche products such as shuttle tankers and offshore support platforms.

In 1997 to 2003 the group underwent a strategic process of change, where the business directed its core areas into three groups; Financial Investment, Real Estate/ Property Development and International Shipping.

"Shearwater is set up with a modern and cost-efficient fleet, an experienced organization, and a solid financial platform. Supported by GC Rieber's extensive industry experience, we believe Shearwater will have a unique position in the market that can also consider further strategic opportunities." 
Dag Rasmussen, Rasmussengruppen.
