Design för ökad flexibilitet av betongpontoner i marinor

Abstract

Due to the current design of SF Marina’s concrete pontoons, maintenance of cables and water lines as well as changes to the configuration of pontoon accessories are cumbersome. Casting channels for cables and water lines, as well as customizing each pontoon for features such as the placement of mooring bollards, also leads to increased manufacturing costs. The goal of this thesis is to develop a product concept resulting in increased flexibility and user-friendliness of the pontoons, while simplifying their manufacturing process and maintaining essential functions. The work begins with a preliminary study, during which the use of the current product is observed, and boat owners and marina staff are interviewed. Calculations of critical load cases are made, and concept requirements are defined based on these calculations as well as insights from the preliminary study. Concept ideas are generated, partial solutions from different ideas are combined using a morphological matrix, and a concept is selected by filtering the resulting combinations using a PNI-method. The concept’s components are then further developed to increase their functionality and enable their manufacture. The final concept involves a solution consisting of an aluminum profile, mounted on the side of the pontoon. Cables and water lines run through an easily accessible space, while mooring bollards and mooring booms are clamped on and can be moved sideways independently of each other, enabling several different configurations. This solution thereby increases flexibility and reduces the effort required to modify the pontoon’s layout, while also simplifying manufacturing by eliminating the need for cast-in channels in the concrete.
