Improve excavation efficiency and deliver cost savings with JetFlow 100.
The JetFlow 100 controlled flow excavation system cuts through tough soils and clays up to 100 kPa - without the requirement for additional jetting equipment.
Perfect for seabed conditions with higher soil shear strength, JetFlow 100 enhances operational efficiency and reduces deck spread complexity.
This dual-function tool also complies with DNV2.7-3 subsea lifting standards and has a compact footprint.
JetFlow 100 is suitable for a wide range of CFE applications including pipeline and cable trenching, backfilling, de-burial of cables, pipelines and subsea assets, seabed preparation and pre-installation excavations, free-span rectification, and decommissioning excavations.
Easily remove stubborn, high shear strength soils safely and quickly with JetFlow 100.
Designed, tested and built in-house by James Fisher
Advanced capabilities
- Cuts through soils/clays and provides mass flow excavation in one pass
