Abstract
Support vessels for platforms in the oil industry have operation versatility and capacity for structural modification. This article presents a proposal for the installation of a crawler crane on the main deck of a platform support vessel, which will carry out offshore maintenance operations. This proposal includes the results of the structural analysis of the main deck, considering its reinforcement with two NVA36 beams. This structural analysis incorporates the integrity of the main deck, taking into account the crane and loads through finite element method (FEM) models. The obtained results show that the main deck requires the proposed reinforcement to decrease the maximum stresses of von Mises up to 218.71 MPa for the structure of the main deck and 201.67 MPa for the reinforcement beams. These maximum stresses do not exceed the allowable and yield stresses of the main deck material. The reinforcement of the main deck that supports crawler crane allows safe operation of the offshore support vessel.
