Dredging vessels are designed for excavation activities usually carried out at least partly underwater, in shallow water or fresh water areas with the purpose gathering up bottom sediments and disposing of them at a different location, mostly to keep waterways navigable. To perform these tasks dredgers are equipped with different specific dredging devices.

Wärtsilä SAM Electronics provides customized solutions for power generation and distribution as well as electric drives. The product scope for dredger applications is completed by a dredger control technology, designed in partnership with Vosta LMG, which permits control of the entire dredging process.
