Finnish propulsion specialist Steerprop<\/a> has expanded its range of retractable thrusters with its biggest unit to date. Designed for offshore vessels and workboats that need high-performance station-keeping or thrust boost capabilities, the SP 45 R will be introduced on several offshore, renewables and special purpose vessels.<\/p>\n \u201cSteerprop provides propulsion that won\u2019t let you down, proven time and again on vessels operating in the most challenging conditions,\u201d said Steerprop director, sales & project development, Juha Rekola. \u201cWhen we first looked at retractable thrusters, it was clear that some aspects were letting operators down. After rigorous testing, we believe we have designed the most robust and reliable retractable thrusters on the market.\u201d<\/p>\n Working with vessel operators and designers, Steerprop identified that the sealing and locking mechanisms are often a weak point for retractable thruster designs. The R series minimizes downtime, maintenance demands and space required onboard while delivering the high-performance propulsion and dynamic positioning capabilities needed by today\u2019s offshore vessels.<\/p>\n The patent-pending seal design minimizes downtime by actively managing water ingress, with low maintenance requirements that can be performed from inside the vessel during normal operation. A floating housing moves with the stern tube to keep the seals in contact even at high speeds and sea states, and a simple scraping solution reduces marine growth on the stern tube\u2014a primary cause of seal damage.<\/p>\n A hydraulic locking and lifting mechanism ensures maximum reliability and addresses another common challenge for traditional retractable thruster designs\u2014available deck space. The compact, zero-clearance solution fits entirely below the main deck of most standard vessel designs, ensuring that the prime real estate onboard can be fully utilized for the ship\u2019s main mission.<\/p>\n The fixed-pitch propulsion concept further reduces maintenance demands, while delivering the propulsion performance for which Steerprop\u2019s existing range of thrusters is renowned. Like the other thrusters in the R series<\/a>, the SP 45 R is available in L-drive, permanent magnet or induction electric motor configurations\u2014fitting a range of vessel power configurations. Electric steering gear ensures the precision needed for dynamic positioning, while power and propeller size can be adapted to meet the specific requirements of each application, within a power range of 900 to 4,000 kW.<\/p>\n Rekola added: \u201cAs offshore vessels increasingly rely on dynamic positioning, retractable thrusters are becoming an essential element of high-performing vessel designs. The SP 45 R works in conjunction with our main azimuth and tunnel thrusters to provide complete control in propulsion and station keeping.\u201d<\/p>\n The post Steerprop introduces its largest retractable thruster yet<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\n
