Since its inception in 2005, Volvo Penta’s IPS integrated propulsion system has continued to grow and develop to make navigation simpler and more sustainable on two fronts: the owner’s environment and pockets. Initially, as soon as it was presented, the IPS was intrigued by its characteristic of having the propellers, double and counter-rotating, facing forward and not aft. After the initial surprise, the IPS began to take root in the world of motorboats, gaining more and more success.
In contrast to the traditional axis line, in the IPS system the propellers work under optimal conditions because they do not suffer any kind of turbulence, because in front of them there is nothing and they have an optimal “grip” on the water. This means, numbers in hand, reduced consumption by up to 30%, higher maximum speed, up to 20% compared to a traditional system, and greater autonomy of navigation. Less fuel consumption means lower emissions, therefore a more sustainable boat. To consecrate its success was then added the possibility of managing the wheelhouse (also simplifying the mooring) with a joystick.
IPS is appreciated not only for its performance, but also for its maneuverability. The strength of this system is in the ability to individually maneuver each propeller exponentially increasing the control. In addition, the system EVC (Electronic Vessel Control) integrates the mechanical and electronic component on board and makes everything within reach of the joystick. In this way you can also keep track of all information on the status of the boat at sea and not.
Waiting for the hybrid, due in 2021, Volvo Penta has made it easier to monitor and maintain the IPS system by adding sensors that detect the differential pressure of the oil above the filters to quickly identify if they are clogged. The oil change system has been simplified and a sensor has been added that immediately detects the entry of water, avoiding damage to the transmission. To make life easier for shipowners, materials have been updated with the addition of high-strength steel. The propeller shaft seal, input bearing holder and upper shaft and bearings have also been redesigned for even longer life.
