This report presents a design study focused on a floating offshore barrier for catching sargassum to protect the coastline of the Yucatan region in Mexico. The research was conducted as part of the multidisciplinary course offered by the Civil Engineering faculty. The study involved five students from diverse disciplines: two hydraulic offshore students, one hydraulic engineering student, one structural engineering student, and one chemical engineering student.

Macaulay's method, which makes use of singularity functions to describe external forces on beam structures, is extended for two-dimensional structures. Furthermore an extension on the method of Macaulay is described for singularities in the rotation and displacement field of the structures, based on the article of Falsone, G. (2002), ‘’The Use of Generalised Functions in the Discontinuous Beam Bending Differential Equations’’ out of the International Journal of Engineering Education. Additionally the modeling of springs is added to the extension of the Macaulay's method.
