It discusses 1) using sensors and deep learning to capture navigator expertise, 2) developing a ship intelligence framework with key components like DNNs and safety systems, and 3) conducting experiments in bridges and at sea to advance situation awareness for autonomous ships.
This document discusses a proposed framework for an intelligent collision avoidance system for autonomous ships. It begins with introductions to transportation systems, ship maneuvering challenges, and the potential for artificial intelligence (AI) solutions. It then presents the Ship Intelligence Framework (SIF), which uses deep neural networks trained on real-world shipping data to mimic human navigator behavior. The framework estimates collision risk and determines avoidance decisions, which are then executed through ship control systems. The goal is for AI to overcome challenges of ship navigation by cloning human decision-making.
This document discusses ship collision avoidance for autonomous ships. It proposes a Ship Intelligence Framework (SIF) that uses deep neural networks trained on real-world ship navigation data to mimic human navigator behavior. The SIF has two phases: a training phase where networks are trained to estimate collision risk and determine avoidance decisions, and an execution phase where networks generate avoidance actions. It also discusses how collision risk is estimated and how avoidance should comply with Collision Regulations (COLREGs). The framework aims to develop autonomous ship technology while ensuring regulatory compliance.

Human errors are inevitable. No matter how competent
the people we employ or how much training we do,
human fallibility cannot be avoided. This is why a
resilient socio-technical system must be created to avoid
negative consequences caused by mismanagement of
errors and threats. This is the key to creating a more
advanced and higher level of system safety. Addressing
latent conditions at the workplace, such as bridge
ergonomics, complements such a system.
It is, however, not enough to impart Human Factors’
training to the officers and believe that all weaknesses
will be taken care of. First of all, officers must be
required to have a thorough understanding of the
equipment they use before they are put in charge of a
navigational watch. Second, there must be a consistent
organization, which is not solely depending on the person
in command. Third, ship-specific procedures and
checklists, which are reviewed at frequent intervals, must
be put in place.
This dissertation examines the implementation and use of Electronic Chart Display and Information Systems (ECDIS) on ships. It provides context on the regulatory framework requiring ECDIS, outlines some key ECDIS-related incidents, and discusses objectives around evaluating training requirements and exploring factors that could lead to operator error. The author conducted industry surveys and interviews to research topics like the current understanding of ECDIS, recommendations for training methods, and whether skill fade or operating multiple equipment types could increase the risk of incidents. The dissertation evaluates the findings and provides conclusions on critically assessing regulations and the possibility of errors arising from those potential issues.

This document describes an autonomous sailboat controlled by an Android device. The sailboat uses a Raspberry Pi for onboard computing and sensors to track GPS position, stream video, detect pH levels and more. It aims to autonomously navigate inland water bodies while transmitting real-time data via WiFi to a stationary server for monitoring. The mechanical design and hardware components like motors, sensors and batteries are selected to be computationally efficient and suitable for onboard implementation. Testing showed the vessel can stably navigate wind trajectories and stay connected via WiFi within a range of a few meters. Potential applications include oceanographic research, water monitoring, weather data collection and surveillance.
This document discusses centralized fault management of docks in marine sensor networks. It proposes a distributed routing algorithm (DRA) and network topology management technique (NTMT) to address issues with existing systems. DRA allows for pre-failure detection of nodes by having nodes send heartbeat messages to neighbors. If a node fails, NTMT selects a replacement node from the smallest affected network partition and coordinates moving related nodes to restore connectivity while maintaining existing links. The techniques are analyzed through simulations which show improvements over previous approaches by enabling pre-failure detection and recovery without significantly increasing path lengths or overhead.

Improvements to Situational Awareness During Approach and Landing Through Enh...Justin Stephen Brown
Pilot workload varies greatly during a typical flight. Technological advances are designed to reduce pilot workload and improve safety by eliminating pilot tasks during the busiest phases of flight - approach and landing. But do these new systems actually increase pilot workload? How do we measure the workload on the pilot? How do we measure safety?

The document summarizes the context and requirements for a resilient positioning, navigation and timing (RPNT) system discussed at a dissemination workshop. It outlines that maritime operations highly depend on GNSS and discusses user requirement domains, including required navigation performance parameters, operational requirements, and geographical coverage needs. The presentation emphasizes that an RPNT system should preserve continuity for users and considers fault tree analyses for evaluating integrity and continuity requirements, suggesting a multi-system receiver approach could provide redundancy to cope with faults.
This document outlines the various courses and training covered in a maritime academy program, including navigation, celestial navigation, radar/ARPA, ECDIS, rules of the road, GMDSS, bridge simulation, fire drills, man overboard drills, security, stability, cargo operations, medical training, and tanker cargo operations. The training emphasizes practical skills like navigation, cargo handling, emergency response procedures, and compliance with international regulations to prepare students for work aboard commercial vessels.
This document provides a summary of an individual's military experience and training. It details their roles in the Navy from 1995 to 2015, including occupations as an Operations Specialist, Seaman, and Seaman Recruit. It also lists relevant course they completed, such as courses on the Global Command and Control System, radar operation, and equal opportunity management.
Project Horizon was a European research project that used ship simulators to study the effects of fatigue on cognitive performance of watchkeepers under different work patterns. The document summarizes the background and findings of the research. It notes that shipping is a 24/7 industry where long work hours and irregular schedules can lead to fatigue. Previous studies have linked fatigue to maritime accidents but more research was needed. Project Horizon involved 90 officers tested on bridge, engine, and cargo simulators over realistic 7-day scenarios to advance understanding of fatigue and identify safer work patterns.
The document discusses advanced systems for managing operational risk on ships through improved collision warning systems. It notes that current fixed alarm limits can lead to unnecessary alerts. The proposed approach uses data from sensors, AIS, and VDR combined with fast-time simulation to dynamically calculate situation-dependent alarm thresholds based on factors like visibility, vessel type, and maneuvering constraints. This adaptive system aims to better identify real collision risks while reducing superfluous alerts by an estimated 40%. Field studies on commercial ships provided data on existing collision warning configurations and operator experiences to help develop enhanced alarm management standards.
Smart ports: towards a high performance, increased productivity, and a bette...IJECEIAES
Ports are currently competing fiercely for capital and global investments in order to improve revenues, mostly by improving performance and lowering labor costs. Smart ports are a fantastic approach to realize these elements since they integrate information and communication technologies within smart applications, ultimately contributing to port management improvement. This leads to greater performance and lower operational expenses. As a result, several ports in Europe, Asia, Australia, and North America have gone smart. However, there are a lot of critical factors to consider when automating port operations, such as greenhouse gas emissions, which have reached alarming proportions. The purpose of this study is to define the most essential tasks conducted by smart ports, such as the smart ship industry, smart gantry and quayside container cranes, transport automation, smart containers, and energy efficiency. Furthermore, it gives a model of the smart port concept and highlights the critical current technologies on which the ports are based. Each technology’s most significant contributions to its development are noted. This technology is compared to more traditional technologies. It is hoped that this effort would pique the curiosity of fresh researchers in this sector.
This paper discusses research into developing an onboard decision support system to assist in person overboard accidents. The system would provide situation-dependent maneuvering assistance to safely return to the location of the person in the water. The research is motivated by new information and communication technologies and aims to take advantage of the IMO's e-Navigation initiative. The researchers are investigating automated detection of a person falling overboard and potentials for enhanced maneuvering support. Based on case studies and existing equipment, they propose a concept for advanced decision support in emergency situations within the context of e-Navigation. The research is part of an EU-funded project to develop onboard safety systems.
Oceanographic instrumentation technicians play an important role in collecting scientific ocean data by maintaining instrumentation on platforms like ships, moorings, and autonomous vehicles. They are responsible for all aspects of data collection, from deployment to delivering documented data to users. Technicians must integrate components with platforms, deploy and recover systems, operate and maintain systems, and manage and quality control data. To perform these tasks well, technicians require knowledge of safety regulations, technical standards, instrumentation, and data management, as well as skills in communication, troubleshooting, and computer use. They must be organized, self-motivated, and able to work independently in remote environments.

Reverse Engineering Approach for System Condition Monitoring under Big Data a...Lokukaluge Prasad Perera
This document proposes a reverse engineering approach using advanced data analytics to monitor ship engine condition from big data. It involves clustering raw sensor data into different engine operational modes. Each cluster represents a linear "digital model" of the system. Descriptive analytics identify data anomalies, which diagnostic analytics then recover or remove. Predictive analytics forecast behavior by connecting digital models. Visual analytics visualize relationships between parameters. Together this creates knowledge for decision analytics using key performance indicators. The approach aims to help industrial digitization by allowing data structures to self-learn, self-clean, self-compress/expand, self-visualize, and develop intelligent models through reverse engineering raw data into system components.
Industrial IoT to Predictive Analytics: A Reverse Engineering Approach from S...Lokukaluge Prasad Perera
A novel mathematical framework to support industrial digitization of shipping is presented in this study. The framework supports a data flow path, i.e. from Industrial IoT (i.e. with Big Data) to Predictive Analytics, where digital models with advanced data analytics are introduced. The digital models are derived from ship performance and navigation data sets and a combination of such models facilitates towards the proposed Predictive Analytics. Since the respective data sets are used to derive the Predictive Analytics, this mathematical framework is also categorized as a reverse engineering approach. Furthermore, a data anomaly detection and recover procedure that is associated with the same framework to improve the respective data quality are also described in this study.
Digitalization of Sea going Vessels under High Dimensional Data Driven Models...Lokukaluge Prasad Perera
Digital models are being developed to handle large datasets collected from Internet of Things sensors on ships. These digital models can help overcome challenges in areas like model uncertainty, erroneous data, and high computational needs. The models are created using machine learning algorithms to identify clusters in ship performance and navigation parameters. They represent the relationships between factors like engine output, propeller characteristics, and vessel trim. Digital models have advantages like being self-learning, self-cleaning, and able to visualize vessel operations. They may help identify sensor faults, reduce data dimensions, and support efficient data handling frameworks.
The document discusses handling big data in ship performance and navigation monitoring. It presents a data handling framework that includes developing digital models from data clusters, using principal component analysis to analyze the clusters, and extracting information to reduce parameters while preserving information. The framework allows for data projection, sensor fault detection, integrity verification from other sources, and data visualization to support decision making. The talk outlines developing these techniques to better handle large scale data from ships.
Various industrial challenges in full scale data handling situations in shipping are considered in this study. These large scale data handling approaches are often categorized as "Big Data" challenges; therefore various solutions to overcome such situations are identified. The proposed approach consists of a marine engine centered data flow path with various data handling layers to address the same challenges. These layers are categorized as: sensor fault detection, data classification, data compression, data transmission and receiver, data expansion, integrity verification, and data regression. The functionalities of each data handling layer with respect to ship performance and navigation information of a selected vessel are discussed and additional challenges that are encountered during this process are also summarized. Hence, these results can be used to develop data analytics that are related to energy efficiency and system reliability applications of shipping.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Transportation Systems
Autonomous Navigation
Autonomous navigation will play an important role in future transportation
systems.
The technologies required for autonomous navigation in land transportation
systems, i.e. self-driving cars such as Tesla, Uber, and Waymo, are in a mature
phase when the environment is structured, i.e. well-defined roads and
communication networks.
The required technological advancements for autonomous transportation
systems in an unstructured environment are subject to more challenging
navigation constraints.
Not only the required technologies for maritime transportation systems can
be more complex and still in a development phase, the infrastructure is in
general inadequate.
A considerable amount of infrastructure and technology challenges has been
encountered by maritime transportation systems in relation to autonomous
navigation.
This project proposes to research on the required fundamental technologies to
support future maritime transportation systems operation under autonomous
conditions.
This requires an understating of the challenges associated with ship
navigation and finding appropriate solutions.

Ship Maneuvering
Vessel Controllability Problem
Vessel position (i.e. the centre of vessel
rotation) : P(x(t), y(t))
Course-speed vector : V(t)
Heading (surge) vector : u(t)
Sway velocity : v(t)
Drift angle : β(t)
Ship manoeuvring consists of complex rigid body motions.
This is due to large bandwidth of nonlinear hydrodynamic and wind force and
moment interactions between environment and the vessel hull and
superstructure, which often generate unexpected and undesirable ship
motions.
Vessels often have a heading vector that deviates from the course-speed
vector, resulting in a drift angle.
Since vessels are not navigating in fully-defined ship routes, one vessel can
encounter other vessels in its vicinity with various course-speed and heading
vectors.
Ship navigators should be aware of such encounters associated with higher
collision risk.

rotation) : P(x(t), y(t))
Course-speed vector : V(t)
Heading (surge) vector : u(t)
Sway velocity : v(t)
Drift angle : β(t)
Full controllability of vessels with rudder and propeller actuators is not
possible and is especially demanding under rough weather conditions.
Vessels present sway-yaw manoeuvring interactions and are thus
under-actuated systems with heavy inertia.
The course-speed vector cannot be measured or estimated with enough
accuracy, i.e. not enough sensor measurements.
The centre of vessel rotation can also change due to the environmental
loads.
Not only the respective navigation vectors but also their positions can change
without any requests.
Vessels are considered as slow response systems with considerable
time-delays in response to discrete control requests.

System Intelligence
Classical Mechanics 2 AI
Various advanced controllers based on classical mechanics have been
introduced by the research community to address this ship controllability
problem , however the outcomes are still not satisfactory.
The main reason is that these mathematical models may not adequately
capture the complexities in ship motions; therefore controller robustness
and/or stability cannot be preserved during ship manoeuvres.
The controller inputs, i.e. rudder and propeller control inputs, are not
continuous and the controller outputs, i.e. heading and course-speed vectors,
may not have adequate accuracy and/or associated time-delays, hence
controller performance can be further degraded.
Though conventional ship auto-pilot systems are based on similar approaches,
such systems may not able to handle complex navigational constraints.
Ocean going vessels are still navigated by humans, especially in cluttered
navigation zones and rough weather, using their knowledge and experiences to
overcome complex vessel motions.
Our aim is to overcome these issues in ship navigation by introducing Artificial
Intelligence (AI) into the ship controllability problem.
That has categorized as Cloning Ship Navigator Behavior.

Self-driving Cars 2 Autonomous Ships
This project proposes to capture and mimic navigator knowledge and
experiences by using deep learning, i.e. deep neural networks (DNNs), as a
ground-breaking technology that facilitates a better solution to control vessels.
A considerable number of sensors should also be on-board and the respective
data should be fused in a perception framework to achieve this objective.
In self-driving cars, the respective driver is successfully replaced by DNNs
trained to mimic human behaviour.
The success in self-driving cars is due to three main factors 1 :
1 collecting and analysing large-scale real-world driving data
sets, including sensor and high definition video/image data, to
support deep learning based digital drivers.
2 holistic understanding of how human drivers interact with
vehicle automation technologies by observing video/image and
vehicle motion data, driving characteristics, human knowledge
and experiences with the new technologies during the training
phase.
3 adequate safety buffer to save lives by identifying how
technology and other related factors can be used during the
self-driving phase, i.e. the execution phase.

Deep Neural Networks (DNNs)
This is a considerable deviation from conventional control approaches in ship
navigation developed in the last decade.
Instead of control flow logics and if-then-else statements, DNNs consist of
state-of-the-art Neural Networks with many layers and millions to one billion
parameters, i.e. the weights of the respective neurons, of nonlinear activation
functions.
Convolutional neural networks are the most popular DNNs for self-driving cars
and those network parameters are adjusted via back-propagation type
approaches.
DNNs require a large amount of real-world vessel navigation data and
hundreds of thousands to millions of forward and backward training
iterations to achieve higher accuracy in navigator behaviour.
DNNs consist of large numbers of identical neurons with a highly parallel
structure that can be mapped to GPUs (Graphics processing unit) naturally to
obtain a higher computational speed when compared to CPUs based training.

System Intelligence
Adequate Safety Buffer
It would be difficult build DNNs as a robust and safety critical system purely
by human training.
Unexpected and undesirable motion and navigation conditions can be
encountered by ship navigation situations.
If the DNNs have not seen such situations during its training phase and
generalization is poor in the execution phase, that could create undesirable
behavior.
A decision support layer with adequate information sources should support
the DNNs to overcome such situations.
Situation awareness and collision avoidance (SACA) is identified as the
minimal decision support facility required to support the training and
execution phases.
This can create an adequate safety buffer to avoid possible collision or
near-miss situations, by identifying moving and stationary objects around the
vessel domain.
DNNs are integrated into the ship intelligence framework (SIF) created in a
conceptual level by the UiT autonomous ship program, while considering the
same main factors of self-driving cars.
