“We are very proud that Asmar has again put their trust in Wärtsilä to be the supplier of this extensive scope of equipment for the Escotillón IV vessels. These specialised vessels require superior performance and we are confident that the Wärtsilä solutions selected will meet this requirement,” says Alejandro König Scheihing, Shipbuilding Manager, ASMAR. “From previous experience, we know and trust Wärtsilä to deliver high quality and reliability in all their products and systems. The rudders and steering gears are the result of cooperation between Wärtsilä and Damen Marine Components. Testing has shown that this results in the required power values being reduced by 3-4 percent at the required vessel speed. The energy efficient rudders are combined with high efficiency propellers, fairing caps and a bulb on the rudders. The full Wärtsilä scope for each ship includes two Wärtsilä 26 main engines and four Wärtsilä 20 auxiliary engines, an emergency generating set, two Wärtsilä gearboxes, two controlled pitch propellers (CPPs) with efficiency rudders and steering gear, the Wärtsilä ProTouch control system, a Wärtsilä tunnel thruster, a main switchboard, a power management system (PMS), two power take-in/take-out (PTI/PTO) drives, two uninterruptable power supply (UPS) systems, the transformers, and a bow thruster drive. The Escotillón IV project, under which these ships are being built, will not only increase Chile’s defence capabilities, but will also allow the ships to be used for humanitarian operations. The order was placed by Astilleros y Maestranzas de la Armada (Asmar), the state-owned shipyard constructing the vessels and it was included in Wärtsilä’s order book in February 2023. The technology group Wärtsilä will supply the main propulsion machinery, as well as a range of other equipment and systems for two new 110-metre long amphibious transport vessels being built for the Chilean Navy.
