PROPELLERS FITTED SELF-ELEVATING WORK PLATFORM

摘要

A propeller fitted Self-Elevating Work Platform (SEWOP) having at least one propeller with rudder positioned at aft and driven by a diesel engine and at least one azimuth thruster positioned at stern and driven by an electric motor is disclosed. While SEWOP is moving in open waters, the propulsion is by the propellers. While near an offshore installation, the SEWOP needs to be positioned and hence the propeller with rudder is used to slowly move towards the installation. At the time of installation, the azimuth thruster is used to assist in maintaining the position of SEWOP.
