Description du poste

A three-hold model is a finite element (FE) model representing three consecutive cargo holds within a ship’s cargo area, typically located amidships. It is commonly used to perform direct strength assessments of ship structures, particularly for bulk carriers and oil tankers.

The preparation and application of the required load cases involve numerous calculations and repetitive modelling operations. This internship aims to review the applicable methodologies and develop tools to improve the reliability, efficiency and traceability of this process.

SCOPE OF WORK

The internship will be structured around four main work packages:

Review of three-hold model load calculation methodologies

Update and enhancement of internal load calculation tools

Development of FEMAP API scripts or macros for automated load application

Validation, documentation and handover of the developed methodology and tools

_________________________________________________________________________________

The student will review the methodologies prescribed by the selected classification societies, such as Bureau Veritas (BV), the American Bureau of Shipping (ABS) and DNV, for the direct strength assessment of three-hold models.

The objective will be to identify, extract and compare the load cases and load components required for application to the finite element model, with particular emphasis on pressure loads.

Based on PRINCIPIA’s existing Excel-based tools, the student will update and enhance the load calculation workflows in accordance with the requirements and methodologies identified during the first stage of the internship.

The objective will be to ensure consistency with the selected classification rules and to prepare reliable input data for the subsequent application of loads in FEMAP.

Development of FEMAP API Scripts or Macros

Once the load calculation tools have been updated, the student will investigate the automated application of the calculated loads in FEMAP through the FEMAP API.

The objective will be to develop and validate scripts or macros, using VBA or another suitable programming language supported by the FEMAP API, in order to reduce repetitive manual operations and improve the reliability, traceability and maintainability of PRINCIPIA’s internal tools.

Validation, Documentation and Handover

The student will document the overall methodology used to create and load a three-hold model in FEMAP. The report will consolidate the results obtained throughout the internship, standardise the modelling and load application methodology, and provide a reference document for future use by PRINCIPIA engineers.

A validation dossier will also be prepared to demonstrate the robustness and reliability of the developed tools, including representative test cases, verification results and identified limitations.
