Résumé

[en] A Greater demand of energy on land has led to an increase in the offshore drilling and energy harvesting activities. The shipping industry has shown a rise in demand for the specialised vessels called the heavy lift ships. These ships are designed to transport goods to the offshore sites for construction and maintenance and also heavy cargo from one place to another by sea. The heavy cargo loading and offloading operations are carried out using powerful cranes present on such vessels. The crane capacities determine the cargo consignments which need to be handled. They form a vital machinery on such type of vessels. When we compare cargo operations with the onshore operation, these are much more complicated both in terms of the cargo handling and transportation.
The work scope of this thesis comprises of review of standard lifting criteria for shipboard cranes provided by DNV-GL classification society. The load on the crane is assessed during the cargo operations. The stresses experienced at different locations are found out using finite element modelling. This data is then processed for fatigue analysis.
The comparative study of crane structure and operation rules created by Lloyds Register and DNV-GL classification society is also carried out. The best-suited rules for the company business are analysed.
Finally, a report summing up all the results, findings is prepared. Some valuable optimisation procedures are suggested which would serve for a better structural and fatigue life for the new coming model for such type of crane.
