Steerprop does things differently. By optimizing for the hull form and the application, our tunnel thrusters meet specifications and minimize lifecycle cost\u2014at the same time dispelling the myth that purpose-designed solutions cannot compete on initial cost or meet short project timeframes.\u201d<\/p>\n<p>Steerprop says that its design approach results in tunnel thrusters that perfectly align with the specific requirements of each vessel. The holistic optimization process covers every detail, including computer analysis of the vessel\u2019s hull and tunnel parameters, with customization of every element\u2014from propeller to motor\u2014available to develop the ideal solution. These design capabilities are increasingly important as operators aim to improve comfort by reducing vibrations, and minimize impact on marine life by reducing underwater radiated noise.<\/p>\n<p>Design flexibility is built into Steerprop\u2019s development approach. As an example, the company does not offer a standard size range of propellers. Instead, each propeller is dimensioned precisely for purpose. <a href=\"https:\/\/www.marinelog.com\/shipbuilding\/steerprop-solutions-picked-for-giant-cable-layer-fleeming-jenkin\/\">Similar<\/a> adaptability can be implemented where needed across the propulsion design. This includes the drive configuration\u2014available in L- or Z-drive and permanent magnet motor or induction motor\u2014as well as adjustments to the mounting and gearbox to improve durability and fit space constraints. This responsiveness and the inherent efficiency of Steerprop\u2019s thrusters translate to low lifecycle costs while retaining competitive capital outlay.<\/p>\n<p>The entire <a href=\"https:\/\/steerprop.com\/solutions\/steerprop-tt\">Steerprop tunnel thruster line<\/a> features fixed pitch propellers (FPP). Compared to controllable pitch propellers, these deliver up to 20% more thrust, allowing for installed power to be reduced and a smaller tunnel aperture to be used, because FP propellers only use energy to generate thrust, instead of spinning at full speed in standby, they also reduce operational costs. This also helps to reduce noise and vibrations.<\/p>\n<p>In line with Steerprop\u2019s Arctic heritage, all units can be delivered also to highest ice class. Uniquely, Steerprop\u2019s tunnel thrusters do not require ice grids to meet ice class, eliminating the effects of ice clogging and reducing maintenance by simplifying access to the propeller.<\/p>\n<p>The most recent tunnel thruster design, the 2,100 kW SP 40 TT, is suitable for deployment on heavy-duty offshore vessels. Larger units for cruise vessels and smaller units for ferries and workboats are also available, with the full range covering 500 to 7,000kW.<\/p>\n<p>The post <a href=\"https:\/\/www.marinelog.com\/news\/steerprop-reports-strong-early-order-book-for-its-purpose-built-tunnel-thrusters\/\">Steerprop reports strong early order book for its purpose-built tunnel thrusters<\/a> appeared first on <a href=\"https:\/\/www.marinelog.com\/\">Marine Log<\/a>.<\/p>\n<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Nick Blenkey<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/www.marinelog.com\/news\/steerprop-reports-strong-early-order-book-for-its-purpose-built-tunnel-thrusters\/?utm_source=rss&#038;utm_medium=rss&#038;utm_campaign=steerprop-reports-strong-early-order-book-for-its-purpose-built-tunnel-thrusters\">Go to marinelog<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Steerprop reports strong early order book for its purpose-built tunnel thrusters The first tunnel thrusters from Finnish propulsion specialist Steerprop will enter service in the coming months.
