The Deep C Jumbo Dredge is a mass flow excavation tool, utilizing high volume suction flow. The Deep C Jumbo Dredge diversifies from conventional mass flow excavation by controlled suction and disposal of sediments. This method provides several advantages such as no fluidisation of seabed, controlled excavation, avoids trench backfilling, maintains good visilibility.
