Design Rationale GeoRanger

Based on the extensive requirements of Geo Plus, Conoship International designed the shallow draught hydrographic survey vessel “Geo Ranger”, including seakeeping analysis, DP capability study, and tender documentations for the shipyard selection. After contract signing between Koninklijke Niestern Sander en Geo Plus, Conoship International also provided the complete naval architecture and construction design and engineering to the shipyard.

Geo Ranger was launched at the Koninklijke Niestern Sander Shipyard in March 2020.
