Cable Selection Considerations for Subsea Vehicles
Nejati Fard, Razieh; Eidsvik, Ole Alexander; Tedeschi, Elisabetta; Schjølberg, Ingrid (Chapter, 2018)The aim of this paper is to present a methodology for selecting proper voltage level and power cables as a part of the AC distribution system design for subsea vehicles, such as Remotely Operated Vehicles, seafloor trenchers ... -
Constrained multi-body dynamics for modular underwater robots — Theory and experiments
Nielsen, Mikkel Cornelius; Eidsvik, Ole Alexander; Blanke, Mogens; Schjølberg, Ingrid (Journal article, 2018)This paper investigates the problem of modelling a system of interconnected underwater robots with highly coupled dynamics. The objective is to develop a mathematical description of the system that captures its most ... -
Development of an Obstacle Detection and Avoidance System for ROV
Grefstad, Ørjan (Master thesis, 2018)Unmanned underwater vehicles, such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) are commonly used for inspection, maintenance and repair (IMR) missions in the oil and gas industry. This ... -
Finite element cable-model for Remotely Operated Vehicles (ROVs) by application of beam theory
Eidsvik, Ole Alexander; Schjølberg, Ingrid (Journal article, 2018)Increasing autonomy, efficiency and safety for Remotely Operated Vehicles (ROVs) is crucial for future subsea operations and requires accurate models for optimal control, operations and design. This involves precise modeling ... -
Identification of Hydrodynamic Parameters for Remotely Operated Vehicles
Eidsvik, Ole Alexander (Master thesis, 2015)The hydrodynamic parameters that characterize the behaviour of a general work class Remotely Operated Vehice(ROV) are evaluated. This is done by deriving the equation of motion for an ocean vessel moving in 6 degrees of ... -
SeaArm - A Subsea Multi-Degree of Freedom Manipulator for Small Observation Class Remotely Operated Vehicles
Eidsvik, Ole Alexander; Haugaløkken, Bent Oddvar Arnesen; Schjølberg, Ingrid (Chapter, 2018)This paper presents the design of a novel low cost 4DOF fully electric subsea manipulator for small work class ROVs. The manipulator is designed to work on a wide range of typical observation class ROVs ranging from 5 kg ... -
Validation of multi-body modelling methodology for reconfigurable underwater robots
Nielsen, Mikkel Cornelius; Eidsvik, Ole Alexander; Blanke, Mogens; Schjølberg, Ingrid (Chapter; Peer reviewed, 2016)This paper investigates the problem of employing reconfigurable robots in an underwater setting. The main results presented is the experimental validation of a modelling methodology for a system consisting of N dynamically ...
