  • Scenario Models and Adaptive Bridge Requirements (D1.1)

    This deliverable gives background information on our use of scenarios in CASCADe and provides some requirements for the project as a whole. We explain our motivation for using scenarios per se, as well as giving an overview of major accident types directly involving the bridge, or more specifically some malfunction of bridge team management. An informal analysis of the major contributing factors to the accidents is made. The report describes the major operating modes of the bridge and then gives detailed passage plans augmented by descriptions of typical bridge settings in each mode in each passage plan. Each voyage is then modelled in UML to support future analysis within CASCADe. We further give some theoretical details of cognitive aspects of scenario selection since it is our contention that many accidents are caused by a lack of distributed situation awareness amongst the bridge team and this obviously is a cognitive process. Finally we show how WP1 connects to future work packages.

  • Baseline and Evaluation Metrics (D1.2)

    This report details the varied approaches the CASCADe project will undertake in capturing the baseline performance of seafarers when navigating and the measurement of any improvements made by the project thereafter. We start with some baseline features that describe the known limitations of bridge design and how they might change to comply with recent regulations. Then we outline multiple individual and group level phenomena that can impair the performance of bridge level teams. Some of these are within the remit of CASCADe (e.g. influencing communication activity) and some are not (e.g. ill health of the seafarer). Other factors such as decision-making techniques or approaches to risk are more descriptive and can influence safety in either a positive or negative fashion, nonetheless they are obvious candidates for performance assessment. Chapter 3 onwards details 5 key evaluation metrics that may be used singly or in combination during CASCADe. They are the accuracy and timeliness of seafarer’s actions; measurement of the bridge teams distributed situation awareness; confidence and fatigue levels of seafarers (treated separately or in combination); and some measure of how far seafarer behaviour has deviated from ideal normative or regulatory behaviour.

  • Updated Scenario Models and Requirements (D1.3)

    The aim of this deliverable is to update the scenarios and requirements used in CASCADe and first presented in Deliverable 1.1. Changes and extensions are based on the work done and feedback received during the first cycle of the project. In particular, we use the experiences from the simulator sessions and the results of the mariner survey (Deliverable 6.2) to guide this work; in addition, we aim to use the new version of the scenarios as use cases for the tools developed in CASCADe. The extended scenarios will form the basis of the work in the second cycle of the project. This document is to be seen as an extension of Deliverable 1.1; we will refer the reader to the relevant sections as appropriate.

  • Conceptual Framework and Scenarios for Ship Bridge Experiments and Analysis (D4.1)

    The purpose of task 4.1 was to produce hypotheses on how the bridge, as a cooperative system, processes information. Featuring at an early stage in the CASCADe project, a decision was to use this task for two key purposes: 1. To bring in an end user perspective. 2. To help focus the scope of the project. By conducting surveys, focus groups and observations of seafarers, the purpose was to build up a conceptualisation of the bridge from the end-users perspective, with a particular focus on identifying those areas where there are currently problems and therefore there is scope for improvement. The theoretical framework for task 4.1 was the ‘Combined Effects approach’, as used in the Cardiff Seafarers’ Fatigue study (Smith, Allen and Wadsworth 2006). This approach posits that dangerous situations are built up from multiple factors. Whilst the addition of one or more dangerous factors (e.g. fatigue, bad weather) can have an enormous impact on the likelihood of a serious outcome (e.g. collision or grounding), the reverse of this equation is that by addressing one or two problems, significant benefits can be felt. Task 4.1 was focused upon identifying areas where such improvements might be focused.

  • Results from Ship Bridge Experiments and Analysis in Cycle 1 (D4.2)

    The experiments in work package 4 had two separate purposes: 1. To provide data to allow modelling of seafarer actions and behaviour (baseline) for the Virtual Simulation Platform and to provide data on the possible impact of new design concepts developed in the project. These data were therefore required for work packages 2 (Methodology for Bridge Study and Design) and 3 (Study and Design of Adaptive Bridge System). 2. To continue the process of engaging with seafarers in terms of learning from their experience, a process started in deliverable 4.1. Keeping this direct connection with seafarer experience is essential in terms of ensuring the end product(s) of the project are of real value to seafarers. The experiments, performed on the Physical Simulation Platform, therefore aimed to collect information on seafarers’ experiences with our experimental scenarios, and to collect early feedback on design ideas being developed in the project - trialled in the experiments in a rudimentary form.

  • Results from Ship Bridge Experiments and Analysis in Cycle 2 (D4.3)

    Work package 4 in the CASCADe project concentrates on providing data and information for the design and modelling work packages. The work has involved a process of focusing the aims of the project, gradually refining the area of attention to the point where a final product can be produced. The purpose of deliverable 4.3 was to examine the content that might be shown on the shared display in different modes of operation. This information would still be customisable, but would act as a ‘default’ mode for the display in different phases of operation.

  • Final version of all techniques and tools (D2.12)

    This document presents an overview of all techniques and tools (final version) of WP2 “Methodology for Bridge Study and Design” of the project “Model-based Cooperative and Adaptive Ship-based Context Aware Design” (CASCADe). The tools and techniques include two simulation platforms: a Physical Simulation Platform (PSP) and a Virtual Simulation Platform (VSP), a Modelling Tool Suite and Cognitive Seafarer Models (CSMs). CASCADe addresses the study and design of ship bridges as an integrated whole within a Cooperative System Design Methodology. Within this design methodology, the ship bridge is seen as a cooperative system. A cooperative system is composed of human agents and machine agents cooperating to the achievement of some common, super-ordinate goals, defined by task hierarchies, accessing a shared set of resources while being immersed in an environment.

  • Final Report on the physical and virtual demonstrator (D5.6)

    This deliverable describes the functional equivalence of the Physical and Virtual Demonstrator. It is based on the prototype deliverables D5.4 Physical Demonstrator - Final Version and D5.5 Virtual Demonstrator - Final Version. The Physical Demonstrator focusses on the three parts: bridge design layouts (SYM), console application (RAY) and pilot application (MAR) explained in detail in D5.4. The Virtual Demonstrator is a replicate of the Physical Demonstrator and combines models of bridge systems, user interfaces, vessel, environment and all human and non-human agents explained in detail in D5.5 and is purely based on computational models. The Virtual Demonstrator (by OFF/BMT) allows us to evaluate bridge designs at early development stages by using computational models of virtual seafarers that mimic task execution, situational awareness, human-human as well as human-machine cooperation of real seafarers. Besides the simulation of new bridge design ideas for evaluation, the Virtual Demonstrator enables to show new design ideas corresponding to RAY´s console application and MAR´s pilot application. Therefore it is shown, how new console/pilot applications can be modelled using Virtual User Interfaces (VUI) and using Cognitive Seafarer Models (CSMs).

  • Report on the new bridge design methodology (D2.13)

    This document is a report about the new CASCADe ship bridge design methodology based on the tools and techniques developed in the project. This new methodology has been applied during cycle 1 [month 01–19] of the project to design the CASCADe ship bridge, and then into making the demonstrators. We now derive the lessons learned during this process. D2.13 therefore capitalizes on the methodological developments during the project's first cycle, in an attempt to provide methodological improvements (in the form of techniques and tools) to the design methodologies currently used. In particular it attempts to satisfy the requirements for bridge design improvement from a human factors perspective. Furthermore, international guidelines are fostering to move forward human-centred design processes, e.g. e-nav HCD & SQA Guideline or ISO 9241.

  • Actual Level Bridge Study and Design (D3.4)

    This deliverable presents the results of T3.3 (Actual Level Bridge Study) and T3.4 (Actual Level Bridge Design) after their two instantiations in the project's cycle 1 and cycle 2. The results of T3.3 and T3.4 during cycle 1 have already been presented in D3.2 (Actual Level Bridge Study and Design). This deliverable - D3.4 - is an evolution of D3.2, where new content, related to actual bridge study and design performed during cycle 2, has been added.
