Propulsion system

Fungsi dan jenis propeller yang dipakai di kapal

Propeller (baling-baling) sebagai alat utama penggerak kapal memerlukan suatu pendesaianan yang tepat untuk menghasilkan gaya dorong yang cukup dan searah dengan pergerakan kapal.

Propulsion system

Wartsila coastal and inland waterway propellers

Coastal and Inland Waterway Propellers are available in Bronze or Stainless steel. They are tailor-made with 3, 4, 5, 6 or 7 blades. The accuracy can be according to ISO class II, I or S. Wärtsilä has the capability to deliver fixed pitch propellers for any diameter above 1000 mm, although for the coastal and inland waterway segment they are seldom larger than 3500 mm

Wartsila EnergoFlow

In today’s increasingly competitive shipping environment, you need solutions that not only increase your efficiency, but that are also reliable and have a short payback period. Wärtsilä EnergoFlow is an innovative and cost-effective pre-swirl stator that increases fuel efficiency by up to 10% – without increasing maintenance needs.Wärtsilä EnergoFlow creates optimal inflow for the propeller by guiding one side of the stern flow in the opposite direction to the propeller rotation, generating pre-swirl. The solution consists of multiple curved fins and a ring attached to the ship’s hull to prevent the power losses that typically occur in a propeller’s slipstream.
