Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency
It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”. This article offers a few comments from the perspective of a propeller designer…
Dongara Marine Delivers Ferry in Western Australia
Placing a board deck across two canoes, to make a broad flat and stable surface for transporting passengers and freight, was often done to form early ferries. The true catamaran is an evolution of that practical design concept. In recent decades, Australia has led in the development of all shapes and sizes for aluminum catamaran ferries.In December 2019, Dongara Marine of Port Denison delivered a very practical 148-seat, 24- by 5.5-meter ferry to Western Australia’s Public Transport Authority.

Cummins to Power Kuching Cross-River Ferry
So many cities are built on rivers for obvious reasons of transport up and down but also as ports for foreign trade. But not all of a port city’s trade is up and down the river. People and vehicles must also cross the river. Bridges are great and most cities have one or more, but they are expensive and they lack flexibility.In Kuching, Sarawak this cross-river traffic created the niche for a ferry. Located on the broad, flat, estuary lands of the Sarawak River the city’s single bridge is some kilometers up from the sea.
