Pile dredgetool – PDT

A simple and versatile pile dredge tool that facilitates effective pile dredging operations and marine growth removal

Overview

Highly effective soil plug removal thanks to an ingenious dredging configuration

In response to rising demand for effective pile dredging and cleaning operations, Seatools developed a new pile dredge tool. During the development process, several different concepts were explored, developed, and reviewed, which led to the selection of the tool’s simple and effective design – simplicity that results in great effectivity and low costs, while achieving high excavation rates.

Thanks to its design and its broad applicability, the tool has a distinctive character. Without much effort, the tool can be adjusted for the excavation of other pile sizes. Although the standard configuration is capable of excavating rock layers with rock diameters of up to 150 millimeters, the excavation tooling can be adjusted to cope with even more demanding soil conditions.

This pile dredging tool can be delivered in various configurations, depending on customer performance criteria and job specifications. Variations include an all-electric configuration, additional pump configuration, eductor pump configuration, additional survey equipment, and rust removal tooling.

Key features

  1. Broad applicability

    The tool is designed such that it is capable of excavating a broad range of pile diameters and soil conditions. The tool’s modular design and the possibility to (easily) mount multiple excavation tools and nozzles types, provides operational freedom and delivers effective pile dredging performances in a wide variety of situations.

  2. Simple, cost-effective design

    During the design of the pile dredge system, simplicity was a key criterion that enabled a cost-effective design and improved equipment reliability.

  3. High excavation performance

    In terms of efficiency, productivity, and accuracy, the pile dredging tool yields high excavation performance, which leads to short excavation times and cost-effective pile excavation operations. The obtained efficiency, productivity, and accuracy gains are enabled by constant nozzle-soil distance, as well as by the in-depth knowledge of Seatools engineers and their experience in the field of subsea excavation.
