MOTIVATION

Especially in times of constantly increasing and developing traffic volumes at sea, a primary goal in the shipping industry is the safe and efficient operation and navigation of vessels. One among other important required regulations for ships is a pre-planned berth-to-berth route which must be prepared by the nautical officer and approved by the captain respectively prior to the ship’s departure. During the route planning process there have been a number of error control features available for both ship and shore-based personnel up to now. Warnings about unsafe water depths or insufficient distances between the ship and shore line are displayed. These functionalities are based on static information only – so far, historic experience and best practices have not been considered. It is desirable to close this gap in the near future.

OBJECTIVES AND APPROACHES

Based on big data analysis, HANSA provides the actors involved with Recommended Routing Corridors - a concept that supports both ship and shore personnel in route planning and monitoring. A Recommended Corridor is the area in which similar vessels have sailed safely through the same waters under similar conditions. Similar vessels incorporate the characteristics of a vessel, e. g. its dimensions and type, while similar conditions refer to meteorological and hydrographic data such as wind, tidal streams and water currents. The core idea of HANSA is to develop these Recommended Corridors from historical vessel traffic data in which the available meteorological and hydrographic information is embedded.

Mariners on board will have an additional method of cross-checking at their disposal to re-confirm correct and safe route-planning. They will also benefit from the nautical experience of other mariners. The Recommended Corridors displayed will support the mariners’ decision whether to execute their manually pre-planned routes or apply changes for an optimized route. At this point it should be emphasized that HANSA is a supporting tool for the mariners but the decision on the executed route remains with them. Vessel Traffic Service (VTS) and Coastal Surveillance System (CSS) operators ashore can experience an improved way of monitoring, assessing, and evaluating entire traffic-related situations in their designated area of responsibility, and consequently act accordingly. In this context, HANSA offers a first step towards autonomous anomaly detection when monitoring vessel traffic. Anomalies are indicated, for example, when ships leave a Recommended Corridor or when they are slower than most of the other vessels within this corridor. In addition to the supporting assistance feature for route planning, the HANSA project is a significant step towards intuitive detection of potential hazardous situations. As a result, incidents with serious consequences are mitigated at an early stage, the overall safety of navigation at sea is improved, and the safety risk for ship crews, vessels, cargo, and the environment is reduced. In relation to ongoing research projects on crew reduction and autonomous vessels, the HANSA project is of particular importance. The integration, implementation and demonstration of the Recommended Routing Corridors has taken place within the e-Maritime Integrated Reference Platform (eMIR) operated by OFFIS, also within the on-board NAVTOR planning station which is used by numerous vessels for passage planning, and within the in-house simulation software inVNE (Virtual Navigation Environment) of in-innovative-navigation GmbH.

Hansa was funded and implemented by the German Federal Ministry for Economic Affairs and Energy (BMWi) and MarTERA.

DELIVERABLES

D1.1 Concept of Recommended Routing Corridors

The main aim of this document is to define the concept of “Recommended Corridors”. The principle is to use a large volume of tracking and position data from Satellite AIS, Terrestrial AIS and AIS from onboard vessels as well as weather data, to do big data analysis and provide recommended corridors for marine traffic based on the information about vessels which have sailed those navigable waters in the past. In this way HANSA may help to “streamline” traffic along the complete route, berth to berth, and create “virtual TSS”; the “virtual TSS” will in this case correspond to the way vessels actually travel. Read more...

D1.2 Corridors in Planning and Monitoring

This document gives a final definition of Recommended Corridors based on the initial definition given in Deliverable 1.1. As stated before, a large volume of historic AIS messages and historic weather data is analysed in order to derive traffic pattern. The analysis considers vessel’s attributes in combination with the prevailing weather conditions. Furthermore, this document presents the attributes of the vessels to be used for the analysis. One contribution of HANSA will be the calculation of Recommend Corridors for similar ship types. For this purpose, rules for grouping vessels will also be presented. Read more...

D2.1 Data Collection Report

This document presents the selected data sources, the designed data model and the architecture of the HANSA system. It provides description of sources that have been identified / available, the results of preliminary analysis of data samples from these sources and the list of sources that have been selected to be used in the HANSA project for generating the recommended corridors (Section 2). Further on, the document presents the proposed architecture of the HANSA system (both logical and physical) with components for data retrieval, fusion, storage and analysis (Section 3). Finally, the data model is described (Section 3). It was designed taking into consideration categories and types of the selected data as well as the goal to process and analyse the data in en efficient manner. Moreover, the data model focuses on optimization of data storage and required disk space. Read more...

D 2.1 Appendix 1  - Report on Preliminary Analysis of AIS Data

This document provides basic descriptive statistics about four vessel features: type, draught, dimensions, and destination. Following Raymond (2016), draught information is provided in two kinds of AIS messages. Type 5 messages (static and voyage related data) are the most common source of that information. Additionally, a subtype (with Designated Area Code set to 200 and Functional ID to 10) of type 8 messages (inland ship static and voyage related data) contains such information as well, but they are far less popular. Ship type information can be obtained from the two types mentioned above as well as from type 19 (extended class B CS position report) and 24 (static data report). Regarding ship dimensions, this information is transmitted in types 5, 19, 21 (aid-to-navigation report), and 24. Therefore, this analysis has been narrowed down only to type 5 messages, received in January-December 2015 from Orbcomm satellites (for the whole globe). The analysed dataset contains 1,390,219,742 messages from 425,166 unique MMSI numbers. Read more...

D3.3 Recommended Routing Corridor Service

This document presents a web service that was developed in the HANSA project in order to make both the mesh and recommended corridors available to external components (e.g. systems and applications used by the project’s partners). A recommended corridor is provided by the service based on a query from external components, specifying e.g. a ship and a voyage for which the route should be planned. The service uses the mesh(es), previously generated by the HANSA system (a conceptual representation of all possible routes at sea, see Deliverable D3.1 and D3.2 for more details) to determine the recommended corridor. There are two types of requests available in the service: 1) provides the mesh for a specified maritime area; 2) provides the recommended corridor as the fastest or the shortest route, based on the data provided in a query. Read more...

D 4.1 (Web) Service and Configuration Tool

Subject of this Deliverable is the description of the developed algorithms in order to detect anomalous vessel behavior automatically. The automatic detection of anomalous vessel behavior is a challenge that arises from the expected further increasing traffic numbers at sea in the future, which will be accompanied by an increased collision risk. Automated sea area surveillance system that detects potentially dangerous and anomalous behavior and generates an appropriate alarm for the VTS officers is a promising pre-emptive action in this context.

Besides voyage planning, one aim of the HANSA project is to investigate on methods for automatic anomaly detection. This Deliverable describes the findings of the appropriate work package. Read more...

D 5.1 Corridors in Planning and Monitoring

The preceding work results of HANSA included data acquisition, preparation and analysis in order to extract the most common traffic patterns in form of a mesh. Based on this mesh, the Recommended Corridor is calculated, which can be accessed using an API. This API and its functionality to provide the mesh and Recommended Corridors will be referred as HANSA Services in the remaining document.

The aim of the work conducted in work package (WP) 5 is to integrate this API into the existing Maritime Safety and Security Information Exchange System (MarSSIES) that is currently applied by the Maritime Office in Gdynia to surveil the polish territorial waters in the Baltic Sea. In addition to this, the goal was to integrate the HANSA Services into the e-Maritime Integrated Reference Platform (eMIR), which is used to develop and test innovative maritime assistance systems.

This Deliverable provides a concept for the prototypical integration of the HANSA Services into MarSSIES and eMIR. Such an integration enables the evaluation and demonstration of the project results in a productive environment as well as in a testbed for maritime assistance systems. Read more...
