Objectives
The primary objective of WP6 is the development
of a software decision support tool for the
assessment of the technical suitability of a
natural gas system (transmission, storage,
distribution, end user infrastructure and
appliances) for mixtures of hydrogen/natural gas
and evaluation of the operational risks. The
tool, incorporating the results of other Work
Packages, should determine the technical
conditions under which hydrogen can be injected
in a defined existing natural gas system, with
acceptable safety risks, acceleration of the
aging processes, drawbacks for the end users
involved and costs related to measures to
overcome unacceptable consequences. Since the
development of the tool is highly dependent upon
the results obtained in the other Work Packages
the main tasks on the Work Package are
concentrated in the second half of the NATURALHY
five year programme.
Description of Tasks
The structure of the Work Package tasks is as
follows:
Task 6.1
Definition of the Tool. On this Task the
initial step of the tool development is
performed. The objective is to elaborate the DST
foundation and obtain global agreement on
functionality and end-user behaviour, which can
be obtained by approving a non-functional
prototype and a Concept Document.
Task 6.2
Prototype, Content and Data Model. Having
completed and approved the Prototype and Concept
Document, a first functional prototype, data
descriptions and initial set of requirements
definitions will be performed.
Task 6.3
Construction of the Tool and Task 6.4 Testing
and Verification of the Tool. Having
completed and validated the DST concepts and
finalised collection of the relevant inputs from
the other work packages, the development effort
will proceed on finalising requirements,
establish test process and criteria and build
the complete tool after integration of the
several modules. These tool development and
testing tasks are planned to be carried out in
an iterative process in accordance with the
availability of input data from the other Work
Packages.
Task 6.5
Deployment and Validation. Finally, after
elaborating a first version of the DST, it will
be tested on real end-user situations in the
Netherlands, Greece and Portugal. This Test will
go from the first deployment up to the end of
the Naturalhy programme allowing for at least
one complete revision and iteration after
end-user feedback.
Current Status of
Work Package Activities
During the first three years of the project WP6
commenced with preliminary activity in preparing
the Definition of the Decision Support Tool,
Task 6.1. This involved interaction with
other Work Packages and potential end users to
formulate an overview of this definition of the
tool. A major novelty was also introduced: the
adoption of the Dynamic Systems Development
Methodology – DSDM, a standard software
development methodology. By this decision, the
WP6 Project is using a common, internationally
recognised, development framework to the benefit
of independent auditing, quality assessment and
easier detailed planning and planning control.
As such, this improved plan, copes with the
changing requirements, iterative and stepwise
development approach and content elaboration.
Additionally, as work progressed on the other
Work Packages during Year 4, further details
were available and brought to the WP6 schedule.
At the end of Year 4 Task 6.2 Prototype,
Content and Data Model tasks have been
completed with the issue of the DST Concept
Document, the Global DST Data Model
and documents detailing the DST Initial
Specification Requirements and Topology -
Description of Gas Infrastructure. The main
software development, Task 6.3 Construction
of the Tool, is in an advanced state of
progress with some software modules completed
and with some WP specific modules awaiting final
data from the other technical Work Packages, WP1
to WP5. Based on current forecasts for these WP
inputs the final version of the DST is scheduled
to be completed by WP6 in Month 58 (February
2009) ready for validation testing with three
selected gas companies.
