• A strategy for robust precision control of an endbody being towed by an orbiting UAV 

      Merz, Mariann; Johansen, Tor Arne (Chapter; Conference object, 2017)
      This paper presents a strategy for end-body positioning maneuvers using a towed cablebody system where a fixed wing Unmanned Aerial Vehicle (UAV) is stabilized in a circular orbit. High precision maneuvers such as object ...
    • Barriers to prevent and limit acute releases to sea 

      Hauge, Stein; Håbrekke, Solfrid; Kråkenes, Tony; Lundteigen, Mary Ann; Merz, Mariann (SINTEF Rapport;A22763, Research report, 2012)
      This report summarizes the work performed in PDS-BIP activity 2: "Environmental barrier indicators". The purpose of the present report is to propose a set of suitable indicators for a specified drilling scenario and to ...

      Formålet med denne rapporten er å vise eksempler på bruk av fjernstyrte og autonome droner i petroleumssektoren og vise hvilke utviklingstrender innen droneteknologi som er viktige. Utfordringer og muligheter for bruk av ...
    • Control of an End Body Towed by a Circling Unmanned Aerial Vehicle 

      Merz, Mariann; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)
      The melting of the Arctic ice cap leads to increased commercial interest in these maritime regions, such as shipping via the Northeast Passage and oil and gas exploration, leading to a need to develop new long-range unmanned ...
    • Optimal Path of a UAV Engaged in Wind-influenced Circular Towing 

      Merz, Mariann; Johansen, Tor Arne (Chapter; Peer reviewed, 2017)
      This paper considers the dynamic optimization of the planned path for an Unmanned Aerial Vehicle (UAV) engaged in circular towing of a cable-body system, such that the motion of the towed endmass is stabilized with minimum ...
