Application Refactoring
DG MARE needed to modernize siloed fisheries applications and thousands of legacy business rules quickly enough to support better maritime enforcement, but manual refactoring would have taken too long and delayed the broader cloud transformation.
Reported impact
DG MARE sharply reduced the time needed to modernize legacy rules, improved the foundation for maritime analytics, and created a more agile public-service platform for fisheries oversight and data-driven enforcement.
Accenture is helping DG MARE migrate fisheries and maritime applications to AWS and uses a generative AI refactoring tool to accelerate one of the hardest parts of the program: rewriting more than 2,000 legacy business rules for the cloud. DG MARE's applications manage vessel locations, fish-catch declarations, and related regulatory data from EU member states and third countries. The target state is Ocean Store, a unified platform that consolidates previously siloed application data for analysis and transparency. To speed the move, Accenture built a large-language-model-based tool that reads DG MARE's existing rule logic, codebase, and documentation, then generates cloud-ready code for the business-rule engine. Developers validate and correct the generated output where needed, while the unified platform creates room for additional analytics such as detecting unusual vessel behavior. The combination of cloud migration, data unification, and LLM-assisted refactoring gives DG MARE a faster path to modern enforcement technology.
Fishing-vessel and catch-declaration data from member states feeds DG MARE applications that are being consolidated into Ocean Store. In parallel, legacy business rules and documentation are passed to the LLM-based refactoring tool, which generates cloud-ready code that developers validate before the new rule engine runs on AWS.
"The result of the cloud migration will be a single platform, called Ocean Store, that unifies and integrates all the data from the legacy applications."
"it uses DG MARE's existing codebase and documentation, enabling high-quality code"
"the tool can refactor each rule in just one minute with 90% accuracy"
"we developed a generative AI tool that uses large language models to understand the rules' logic and automatically generate new, cloud-ready code"
