Year: 2006 Language: english Author: Øyvind Smogeli Genre: Research papers Publisher: NTNU Format: PDF Quality: eBook Pages count: 322 Description: This is a thesis about control of marine propellers. All ships and underwater vehicles, as well as an increasing number of offshore exploration and exploitation vessels, are controlled by proper action of their propulsion systems. For safe and cost effective operations, high performance vessel control systems are needed. To achieve this, all parts of the vessel control system, including both plant level and low-level control, must be addressed. However, limited attention has earlier been given to the effects of the propulsion system dynamics. The possible consequences of improper thruster control are: • Decreased closed-loop vessel performance due to inaccurate thrust production • Increased vessel down-time and maintenance cost due to unnecessary mechanical wear and tear. • Increased fuel consumption and risk of blackouts due to unpredictable power consumption. By focusing explicitly on the propeller operating conditions and the available options for low-level thruster control, this thesis presents several results to remedy these problems.

Description: This is a thesis about control of marine propellers. All ships and underwater
vehicles, as well as an increasing number of offshore exploration and exploitation
vessels, are controlled by proper action of their propulsion systems. For safe and
cost effective operations, high performance vessel control systems are needed.
To achieve this, all parts of the vessel control system, including both plant
level and low-level control, must be addressed. However, limited attention has
earlier been given to the effects of the propulsion system dynamics. The possible
consequences of improper thruster control are:
• Decreased closed-loop vessel performance due to inaccurate thrust production
• Increased vessel down-time and maintenance cost due to unnecessary mechanical
wear and tear.
• Increased fuel consumption and risk of blackouts due to unpredictable
power consumption.
By focusing explicitly on the propeller operating conditions and the available options
for low-level thruster control, this thesis presents several results to remedy
these problems.
