# Otter (and Mariner X) at Norway: deployment

Canonical ID: `22c494f4-a83e-451a-b19b-f12be842957f`

Ørsted, the world's largest offshore wind energy company, operates Maritime Robotics Otter uncrewed surface vessels (USVs) for survey, measurement, and inspection work in Norwegian offshore wind project development areas. Maritime Robotics delivered an Otter USV to Ørsted and was subsequently selected to provide their Autonomous Navigation System (ANS) as the control platform for Ørsted's serial-production fleet of custom offshore USVs. The custom fleet vessels are constructed by Tuco Marine Group in Denmark and designed for continuous operation in harsh offshore conditions for extended periods. By late June 2023 Ørsted had deployed and tested the prototype USV in Norwegian waters in the area designated for one of its first Norwegian offshore wind projects, collecting wind and seabed condition data. Ørsted announced serial production based on the successful prototype with five new custom USVs planned by end of 2023. Ørsted also filed patents covering the uncrewed surface measuring vessel design. The Otter deployment enabled the initial operational and integration testing phase before the custom fleet scale-up.
