Globally Trusted Dredging Sensors with Proven Industrial Quality

For years on end, Seatools dredging sensors have been the preferred choice for reputable dredging companies globally. From precise length and angle measurements to pressure, temperature, and angular velocity sensing, Seatools offers robust subsea sensors, ensuring seamless and efficient dredging operations over the years.

Precision backhoe dredging in tough soil conditions

NMDC required a dependable system to monitor and control the backhoe dredging process for their newbuild Sarab dredger. As they intended to operate in tough soil conditions such as rock, they opted for DipMate Pro. Its specialized design guarantees resilience against extreme dredging conditions, including severe shocks and vibrations, ensuring uninterrupted performance.

Real-time grab dredging in New Zealand with CraneMate

HEB Construction, a leading construction firm located in New Zealand, secured a wharf construction contract. The project involved extensive dredging, employing a clam bucket dredger on a barge. To ensure precise real-time data for the dredging process, HEB opted for the CraneMate system. With CraneMate’s exceptional performance, HEB attained impressive dredging precision, minimizing over-dredging and maximizing efficiency.

Crane automation for efficient UXO removal operations

For the execution of UXO removal operations, Bodac approached Seatools for the delivery of a crane monitoring and automation solution. By taking the DipMate Pro backhoe dredging monitoring and control system as a basis, the system was further extended with custom developed functionalities such as AHC, tool verticality, and automatic grid survey. With automatic grid survey, the survey tool is automatically positioned by means of controlling slew, boom, stick, and tool arm along a defined pattern. By drawing extensively upon our advanced simulation capabilities, the project was delivered successfully within a short time span which allowed Bodac to perform safe and cost efficient UXO removal operations.

Full insight in and control over 1MW of jetting power

Our client HAL Maritiem designed and contracted suppliers for the new water injection dredger of Boskalis named Terra Plana. Underneath this injection dredger, a jet frame that holds two large dredging pumps with a total capacity of 12,000 m3/hr was mounted below the injection dredger.

For this project, Seatools was asked to design and deliver the electrical drive system, including the monitoring and control system for the two submerged pumps. The project’s scope encompassed electronics (including sensors), the umbilical (winch), and transformer.

Grab excavator dredge cycle automation yielding high accuracy and production rates

A new deep-water excavation method was required to excavate in challenging soil conditions at a water depth of 150 meters. To this purpose, the Grab Excavation System (GES) was developed.

Seatools designed and built the grab positioning ROV and its control system, including the controls of the hoist winches. The complete system was executed with full dredge cycle automation. Thanks to its advanced control system, the highly automated GES excelled: production rates of 150 m3/hour in 750 kPa stiff clay at an accuracy level of 20 centimeters were achieved.
