Uncertainty analysis of the hydrodynamic coefficients estimation of a nonlinear manoeuvring model based on planar motion mechanism tests
Real-Time Parameter Estimation of a Nonlinear Vessel Steering Model Using a Support Vector Machine
Design and verification of a sway-yaw control system for Surface Effect Ships using vent valves
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 the crew. A SES is a catamaran vessel carried in part by a pressurized air cush...
Surface effect ship with four air cushions part I: Dynamic modeling and simulation
This paper deals with dynamic modelling and numerical simulations of a Surface Effect Ship (SES) with split cushion. Traditionally, a SES is a catamaran with front and aft seals equipped with lift fans that could fill an air cushion with pressurized air to lift up to 90 % weight of the vehicle. A ne...
Surface effect ship with four air cushions part II: Roll and pitch damping
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 air cushions can lift up to 90 % of the total vessel mass depending on the outpu...
Adaptive Boarding Control System in Surface Effect Ships
Vent valve thrust force for surface effect ships
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 a marine craft with catamaran hull, with flexible stern- and bow rubber -seal s...
Detection of mooring line failures using Dynamic Hypothesis Testing
Abstract This article proposes a novel methodology for the detection of mooring line breakage in thruster assisted position mooring (PM) systems, when no measurements of the tensions on the mooring lines are available. For dynamic positioning (DP) of marine vessels moored to the seabed via a tu...
