Abstract

Colombia's hydrographic wealth is of great importance for the development of the economic sectors throughout the country, and together with neighboring countries such as Peru and Brazil, different needs arising from the difficult access to their more remote populations are shared. This is why, humanitarian missions are carried out through the ships of the Colombian Navy (ARC), which are at the service of the most remote civilian populations, providing, for example, response to disaster situations or covering logistics support. However, in the framework of these operations, problems have arisen due to the absence of having adequate vessels for navigation in shallow waters. To combat the problem, the ARC and the Administrative Department of Science, Technology and Innovation (MINCIENCIAS) have designated resources for Science and Technology Corporation for Naval, Maritime and Riverine Industry Development (COTECMAR) and Colombian Naval Academy (ENAP) to carry out research for the design of a new prototype vessel called BALC-L (Light Boat Logistic Support Vessel) that will meet the needs of logistics and disaster response. This paper focuses on studying and analyzing the behavior of the BALC-L ship in shallow waters, coastal areas and deep-water operations by means of numerical simulation, in order to know its movements and operational limitations under these conditions. This research presents a theoretical introduction, numerical simulation results and the validation of the data obtained from maneuverability and behavior at sea.

Highlights

SeakeepingThis research was developed with the purpose of carrying out a series of simulations of the maneuverability and behavior of the ship BALC-L within an R&D from the Francisco José de Caldas, project bank which is being carried out between ENAP and COTECMAR
The BALC-L class vessel is a ship that is in the design phase at the COTECMAR shipyard, which can be said to be a derivative version of the conventional BALC, but designed to have a shallower draft and access to places of difficult access through the rivers and inner and remote parts of the country
Thanks to studies carried out (Carreño, 2011) with vessels that operate using pump-jet propulsion system in shallow waters, mathematical models have been developed that take into account the NS or "Non-Squat" effect, which translates into an increase of the turning capacity in shallow areas (Clarke, 1998) (Eloot, 2013) for vessels with BALC-L characteristics

Summary

Introduction

This research was developed with the purpose of carrying out a series of simulations of the maneuverability and behavior of the ship BALC-L within an R&D from the Francisco José de Caldas, project bank which is being carried out between ENAP and COTECMAR. The term maneuverability is used from a safety point of view (Sukas et al, 2019) (Aoki et al, 2006), taking into account the importance of the vessel's own shapes, which is especially critical in our case, given the shallow draft required for the vessel to be able to go up rivers as high as possible Due to this situation, maneuverability has gained importance in recent years, to such an extent that different international organizations interested in maximizing efficiency maritime transport, trying to avoid material losses and mainly to protect the lives of crew members and passengers, have made great efforts to standardize regulations to assess the maneuverability of most vessels in most cases.
