SBB (Shore Based Bridge)

Today the Maritime industry is focusing on e-Navigation, i.e. the transmission from Paper to Digital information, and the integration and use of this information on board and on shore (VTS). When it comes to navigational information, NAVTOR has already solution in the market fulfilling these requirements for the Navigator, and we are looking ahead to see what must be achieved regarding navigational information on the way to an autonomous ship in international trade.

NAVTOR foresee the Maritime industry need to go through three phases on our way to the Autonomous vessel sailing internationally:

  1. The e-NAV Phase moving from Paper to Digital
  2. The Demonstration phase, where the concept is introduced, tested and verified within the current maritime legislation
  3. The Change of regulation phase, finally opening up for autonomous vessels build on verification from phase II

The impact of SBB will be to speed up the development of advanced physical testing and type approval approaches for highly automated navigation systems to reduce time to market for European e-Navigation providers, thereby increasing competiveness of European maritime industry.

The eMIR testbed will help NAVTOR to make integrated testing of the suggested SBB, a combined and highly automated cyber-physical system consisting of a SBB, an integrated reference platform and a physical boat, in an operational environment. The aim for NAVTOR is to demonstrate the benefit of a SBB by using the eMIR –platform by OFFIS.

Given a positive demonstration, NAVTOR believe we can have at least three main outcomes:

  • A validation of the eMIR platform in real sea trials
  • The demonstration of a SBB is starting point to work for changing maritime regulation to allow for the Crew reduced vessel and later the Autonomous vessel.

NAVTOR to become a leading provider of SBB to allow for saving for the Ship owners and other benefitting of having access to duplicated bridge information.

Objectives

The main objective for this experiment is to make extensive use of the physical testbed of the eMIR platform for the development of a SBB and by this contribute to the improvement of the testbed in order to support the development of further future navigation solutions.

The objective of SBB will be to develop an on shore e-NAV Station in order to test in an operational environment the functionality of a shore based bridge, moving planning, monitoring and safety-critical navigation functions from vessel to shore.

SBB will introduce a shore based e-NAV Station receiving sensor data such as ship radar, GPS, AIS (automatic identification system), VDR (voyage data recorder), etc. from the Research Boat Zuse. Thus, a navigator will then be able to use multiple data feeds from the vessel for monitoring/navigation and updating the route/passage plan, which will be send automatically on board. In case of an autonomous vessel, the updated route will replace the current route in the ship’s ECDIS and track pilot and thus directly steer the ship according to the new intended Passage plan. A common operational picture on-board and on-shore by means of safe and secure sensor data exchange is obviously essential to execute these functions.

The SBB system will consists of the following three sub-systems and its components:

  • On Board System: The main platform for the on board system is the Research Boat Zuse. Equipped with a so called NaviBox, the sub-system is able to provide sensor data like AIS, Radar, D-GPS, and Compass. In order to get a better overview for the SBB user ashore, the Zuse will be equipped with a front and a rear camera. In addition, the NAVTOR ECDIS will be integrated on board.
  • Communication Link: The SBB experiment will you the existing VHF/LTE communication link of eMIR.
  • On Shore System: The NAVTOR NavStation and ECDIS will be the basis for the e-NAV Station, the shore system of SBB. The data provided by the on board system will be integrated and displayed in the respective on shore system.
