• Passive box-shaped roll damping tank

• Boosting passenger comfort and cargo safety by reducing roll motions and accelerations

• Creating counter moment to the wave excitation

• Tank natural period identical to vessel roll period

• Adjustment of water level for tank period tuning

• Effective at any vessel speed

• Reducing vessel resistance

System Architecture

• Dual redundant serial ring bus

• Automatic data-rerouting for continuous operability even after bus or Local Processing Unit (LPU) failure

• Short circuits also in the PowerBus can be countered while maintaining the operability of the remaining components

• Four versatile inputs, configurable as standard 4-20mA or digital inputs to connect any kind of analog or digital input source

Safety concept

• Two identical cabinets (master &slave), including all associated input and output modules, operate in parallel and with the same software

• A communication between the cabinets monitors all activities of the two cabinets/PLCs

• In case of failure of the master cabinet/PLC, the slave cabinet takes over control via Ring Bus

• Triple input for the power supply (MSB,ESB and UPS)

Floating Condition Control is a flow-controlled anti-heeling and ballast system and integrated into a central control system with PLCs. A key advantage of this setup is that all required operations are fully automated, while remaining under continuous system monitoring.

The control system also includes a loading computer to simulate and optimize the ballasting process, a SCADA system, and a logging function.

AUTO ADJUSTMENT OF FLOATING CONDITIONS

Simply keep your desired condition - Full focus on cargo operation

The key feature of this system is to adjust the floating condition in the three degrees of freedom heel, trim and Draught automatically over a predefined path.

The system allows a flexible selection of parameters as limitations for the operation, such as bending moment limitations, tank usage, min required GMs or others.

For semi-submersible ships and floating docks this system will fully support the operators to undertake automatic docking operations safely.

AUTO COMPENSTATION OF LOAD TRANSFERS

Faster and safer loading operations

In combination with a main crane, upending gripper, lifting arms, jacking legs or any other relative load & position tracking (Load Moments), the FCC System ensures a constant floating position during any transfer of load.

The load can be transferred along the vessel or from an external position. The application can be a ballast supported jacking operation, an offshore installation job, a load skidding transfer in harbour or other similar tasks you can imagine. Also tidal influence are taken into account at the same time.

Key Features

• Unique integration of Valve Remote Control, Tank Gauging, Anti Heeling and Deflection Measurement systems, combined with the SECURELOAD Loading Computer for fully automated Ballast control

• SECURELOAD loading computer calculates ballast water distribution to compensate any kind of transferred loads, ensuring intact stability and longitudinal strength.

• Integrates all load moments that changes vessel´s Floating Condition, such as crane Lift Off operations, considering hook load, boom, and slew angle.

• System with highest measuring accuracy (< 0.5% at all load levels)

• Calculates averages per hour, per day, and for a user-defined period

• Generates „heavy run alarm“ or „torque alarm“ with respect to the customer‘s settings

• Calibrated sensors with self-validation by software in operation

• Maintenance free and easy calibration by crew

• For solid and hollow shaft sizes > 150 mm ø and speed up to 400 rpm
