VESSEL MOTION MEASUREMENT SYSTEM

 

BMO’s technology is developed in-house and transferrable for usage in different maritime sectors. 

The main technology consists of the VesselBlackBox (VBB) which is an integrated vessel measurement package with its own dedicated online data management and reporting service. Information from various sensors and sources is integrated and combined to deliver the insights you need.

 

Fully location and context aware measurements: distinguish vessel state (e.g. in transit, docking, at berth) and run specific measurement protocols.

  • Online functionality: check system status and performance at regular intervals, allow for remote monitoring and fault finding.
  • Online data server: storage, consistency checking and processing of incoming data. Fusion of incoming data with external data (e.g. wave buoys and marine control data).
  • Client portal: Publication of data reports, including but not limiting to: daily vessel reports, event alert emails (near misses, out of range parameters), monthly management reports, live vessel statistics and streaming video.

 

The graph below gives you a rough overview of the main components.

Hardware specification

 

Measurement System

The VBB is used for local data acquisition and storage, providing remote data communication. The data acquisition systems is a rugged industrial design with 240 GB solid state disks (SSD) for maximum robustness and reliability. Power usage is average of 50 VA with 350 VA.

 

Motion Reference Sensor

BMO uses high-end digital six degrees of freedom acceleration sensors. The sensors are MEMS-based and acquire acceleration data at a maximum measurement rate. The sensor contains 3 accelerometers (x, y, z) and 3 gyroscopes (roll, pitch, yaw). The sensors are IP 67 and can handle a maximum impact of 2000G allowing reliable use offshore.

 

Integrated Internet Connection

Capability this delivers two-way communication with BMO’s IT infrastructure through mobile broadband or the vessels/harbour WIFI infrastructure.

 

Power Supply Options

The system has continuous power supply from DC.

 

GPS Receivers

The VBB has an external GPS for improved accuracy and AIS GPS connection for redundancy, eliminating single point of failure. All GPS measurements are SBAS enabled resulting in sub 2m resolution (depending on atmospheric conditions).

 

IP video camera

The VBB has an integrated IP video camera plug in. It allows improved images of access systems on board and transfer activities. The VBB system enables the cameras to record event based and not necessarily full time.

 

Optional components

 

Engine monitoring

When the vessel is equipped with a J1939 compliant engine canbus system BMO can deliver monitoring of critical parameters is sync with the other methods to further enhance the understanding of the offshore operations.

 

Virtual sensor

For vessels with larger distances between the sensor location and the location of passenger lounge or of sensitive cargo, BMO has developed a virtual sensor which allows recalculation of measured values to those at any location. This allows for robust and cost effective mapping of larger vessels. The methodology has been verified against various physical sensors such as the high end Ixblue Octans.
