NONIS - Calculation of a Ship's Center of Gravity

The customer

NONIS srl, an Italian company specializing in industrial weighing, has developed a system designed to monitor the center of gravity of ships under construction.

The system measures the loads borne by each support point on the ship in order to calculate the position of the center of gravity and track the distribution of mass as construction progresses.

Wireless transmission allows measurements to be collected on a PC without running cables near the hull. The data can be viewed in real time and shared on the customer’s computer network. The software for calculating the center of gravity was developed by NONIS.

The need

During construction, the shipyard must know precisely the loads applied to each support and their distribution across the entire ship.

The system must calculate and display the center of gravity as well as the load distribution in both directions: port/starboard and stern/bow.

Our solution

SCAIME supplies the weighing and transmission components that make up the NONIS system’s instrumentation: R10X compression load cells, SILOKIT mounting kits, and ST24 wireless transmission systems.

Operating principle:

The R10X compression load cells measure the loads applied to each support point. The SILOKIT mounting kits ensure their mechanical integration onto the ship’s supports.
Each measurement is transmitted wirelessly via an ST24 system to a USB receiver connected to a PC.
The software developed by NONIS acquires and displays the values for each support point. It calculates the total weight, the longitudinal and transverse load distribution, and the X/Y coordinates of the center of gravity.

R10X Compression Load Cells - Capacities from 1 to 100 metric tons, stainless steel construction, IP68/IP69K protection SILOKIT Mounting Kits - Stainless steel construction, with anti-tilt devices and lateral locking mechanisms. ST24 Wireless Transmission Systems - Transmission of measurements to the NONIS software

Customer benefits

Continuous monitoring of the center of gravity and load distribution during all phases of construction.
Simplified installation: wireless transmission minimizes the need for cable connections near the hull.
Flexibility of use: the system can be reinstalled on different vessels and adapted to various support point configurations.
Traceability of measurements through the recording of values at user-defined intervals and their sharing on the company network.
Comprehensive overview of loads with display of values per support point, total weight, and port/starboard and stern/bow distributions.
Assistance with construction site management: Visualization of the center of gravity’s position allows monitoring of the ship’s balance as construction progresses.
