Cutter Suction Dredger 450 "Daula Peripa" As a sister vessel of the 'Poza Honda', the CSD450 'Daule Piripa', has been delivered in June 2010 by Astinave and Damen to end-user Senagua. Its first project was a siltation job - deepening the river and keeping the feet of the locals dry. Senagua operates a total fleet of four Damen Cutter Suction Dredgers.
