Boarding Control System - for Improved Accessibility to Offshore Wind Turbines
Auestad, Øyvind Fidje; Perez, Tristan; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Espeland, Trygve H. (Journal article; Peer reviewed, 2015)This paper considers the dynamic modelling and motion control of a Surface Effect Ship (SES) for safer transfer of personnel and equipment from vessel to-and-from an offshore wind-turbine. Such a vessel is a key enabling ... -
Boarding control system for improved accessibility to offshore wind turbines: Full-scale testing
Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Perez, Tristan; Sørensen, Asgeir Johan; Espeland, Trygve H. (Journal article; Peer reviewed, 2015)This paper considers the dynamic modelling and motion control of a Surface Effect Ship (SES) for safer transfer of personnel and equipment from vessel to-and-from an offshore wind-turbine. The control system designed is ... -
Design and verification of a sway-yaw control system for Surface Effect Ships using vent valves
Teigland, Håkon; Hassani, Vahid; Auestad, Øyvind Fidje (Journal article; Peer reviewed, 2019)For an offshore worker in the oil and gas industry, the helicopter transport is the activity associated with the highest risk. An alternative to helicopter crew transfers is to use Surface Effect Ships (SES) to transport ... -
Heave Control System For A Surface Effect Ship: Disturbance Damping of Wave Induced Motion at Zero Vessel Speed
Auestad, Øyvind Fidje (Master thesis, 2012)- -
Heave Motion Estimation on a Craft Using a Strapdown Inertial Measurement Unit
Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Fossen, Thor I. (Journal article; Peer reviewed, 2013)This paper deals with heave position and heave velocity estimation on a craft. The estimation is done without any knowledge of the specified craft. An accurate estimation of these signals is useful when one wants to control ... -
Motion Compensation System for a Free Floating Surface Effect Ship
Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Espeland, Trygve H. (Chapter, 2014)This paper deals with vertical motion compensation, or motion damping, on a freefloating Surface Effect Ship (SES) at zero speed. The Motion Compensation System (MCS) works by varying the air cushion pressure of a Surface ... -
Roll damping of a surface effect ship with split air cushion
Tønnesen, Jonas; Bryn, Håkon; Gravdahl, Jan Tommy; Hassani, Vahid; Auestad, Øyvind Fidje (Journal article; Peer reviewed, 2018)This paper considers linear modeling of a surface effect ship (SES) where roll motions are damped by exclusively exploiting a longitudinally split air cushion design. On a SES, the pressurized air cushions can support up ... -
Simulator and Control System Design for a Free Floating Surface Effect Ship at Zero Vessel Speed
Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Halvorsen, Trygve Espeland (Journal article; Peer reviewed, 2013)This paper covers vertical motion damping of a free floating Surface Effect Ship (SES) at zero vessel speed. Vertical motion damping is requested at the bow deck of the SES during offshore wind turbine docking operation. ... -
Surface Effect Ship with Four Air Cushions Part II: Roll and Pitch Damping
Haukeland, Ola Mosebø; Hassani, Vahid; Auestad, Øyvind Fidje (Peer reviewed; Journal article, 2019)This paper introduce damping of roll and pitch motion on a Surface Effect Ship (SES) in low vessel speeds. The SES consist of two side-hulls, a reinforced rubber bow and stern seal skirt system and four air cushion. The ... -
Sway Control on a Surface Effect Ship - using asymmetric vent valve opening
Bua, Nils Haktor; Vamråk, Vegard Moesødegård (Master thesis, 2016)The lateral maneuvering for Surface Effect Ships (SESs) in low velocities is highly limited. Due to SESs hull shape in the bow, it is not an option to use conventional means to get lateral thrust, such as tunnel- or ... -
Vent Valve Thrust Force for Surface Effect Ships
Teigland, Håkon; Hassani, Vahid; Auestad, Øyvind Fidje (Journal article; Peer reviewed, 2019)The Surface Effect Ship (SES) holds promise as a viable and appealing alternative for transferring crew to offshore wind farms and oil platforms due to its superior seakeeping capability, high comfort and speed. A SES is ...
