Brunvoll AS of Norway reports that demand for its new custom-built thrusters is running high. The company has a long history of building thruster units of all types for a wide range of vessels, from cruise ships to offshore ships and cable layers. Its line-up includes its renowned retractable tunnel thrusters, as well as combined tunnel and azimuthing units, various non-retractable azimuthing units, and low noise 'Super Silent' thrusters. Recently the company identified a need for what it calls customized thrusters, units that are not only designed to meet the specific propulsion and maneuvering requirements of individual vessels, but housed in a purpose-built module to suit the hull structure of a ship, that reduce the time it takes to install the unit.
