Análisis técnico económico para propuesta de recuperación y puesta en operación de dragas de TOLVA en el mercado nacional

Abstract

Dredging with hopper vessels in the seas is an important productive activity for the maritime sector, it prevents the accumulation of sediments, flooding and ensures the mobility of vessels. This research work is aimed at the hopper dredgers of the SERDRA company. The objective is to propose a production model with technical support and a financial study that guarantees the sustainability of the company. The critical drops in annual productivity have been the consequence of the lack of maintenance and the poor condition of the units. To solve this, capital investment is proposed to change one dredging unit and manage the maintenance of another. Thus, a dredging production plan has been developed for the fleet, including major maintenance projected over 10 years based on customer needs and the frequency of dredging. It is estimated that a dredging volume of 21,107,498 m³ (years 2024-2033) will be obtained, compared to 14,793,900 m³ (years 2014-2023). It was established for the Nueva Loja dredge at the end of 2024 that the dredging efficiency would be 0%. On the other hand, with the investment in a new dredger, by the end of 2033, 100% efficiency in the hopper dredger could be obtained and a cumulative efficiency of 65.4%. The survey of total annual costs determined that 5,275,391 million dollars are required annually to sustain the operations of the entire dredger fleet.
