Measuring ship motions
OCTOPUS-TMS comprises a very reliable set of instruments designed for the measurement of ship motions. OCTOPUS-TMS was developed in co-operation with MARIN and end-users. OCTOPUS-TMS is designed to deliver highly stable measurements with a minimum of internal disturbance. OCTOPUS-TMS is the perfect cost-efficient solution when it comes to measuring motions, velocities and accelerations of vessels with a high degree of accuracy and a large flexibility.
High performance MTi motion sensors for ship and cargo
To measure motion, velocities and accelerations, the OCTOPUS is connected with either one or three MTi Motion sensor(s) which are installed on the vessel. The obtained information can be stored and displayed real-time. The One Sensor System is widely used on container vessels. It measures the angle and period of roll and pitch. This setup is used in combination with OCTOPUS-Onboard to detect the risk for parametric roll. The sensor is directly connected to the OCTOPUS PC on the bridge.
Three Sensor OCTOPUS-TMS is used for installation on vessels where a higher degree of accuracy is required or on vessels where multiple critical locations have to be monitored.
Typical applications are Heavy Lift vessels and Crane vessels. With a three-sensor setup OCTOPUS-TMS can monitor motions, velocities and accelerations in real-time in any virtual sensor location, typically the cargo CoG, a crane tip or a container position. In addition to this, a separate sensor can be placed on the cargo to measure cargo accelerations directly.
