The study of water waves is significant for researchers working in many branches of science. The behaviour of waves can be studied by observation or experimental means, but theoretically, mathematical modeling provides solutions to many problems in physics and engineering. Progress in this field is inevitable, with those who work in mathematics, physics, and engineering putting forth interdisciplinary studies. Jacobi elliptic functions are valuable mathematical tools that can be applied to various aspects of mathematics, physics, and ocean engineering. In this study, traveling wave solutions of the general Drinfel'd-Sokolov-Wilson (DSW) system, introduced as a model of water waves, were obtained by using Jacobi elliptic functions and the wave dynamics were examined. The extended Jacobi elliptic function expansion method is an effective method for generating periodic solutions. It has been observed that the periodic solutions obtained by using Jacobi elliptic function expansions containing different Jacobi elliptic functions may be different and some new periodic solutions can be obtained. 3D simulations were made using MapleTM to see the behaviour of the solutions obtained for different appropriate values of the parameters. 2D simulations are presented for easy observation of wave motion. In addition, we transformed the one of the exact solutions found by the extended Jacobi elliptic function expansion method into the new solution under the symmetry transformation.

“…Indonesia has abundant marine potential, both the fisheries sector and even the oil and gas sector off the coast of Indonesia (Fadhilah et al, 2019). In the last decade, increasing interest has been in installing heavy and complex underwater equipment (de Andrade et al, 2023). Many companies build offshore platforms (platforms or rigs) in deeper seas to obtain satisfactory results.…”

AHTS (Anchor Handling Tug Supply) is a ship specifically designed to support the operation of offshore building systems. Supply vessel or AHTS equipped with a towing pin, shark jaw. Towing winch, anchor handling winch, and tugger winch support work activities in the offshore industry (platform or riq). This research aims to analyze the factors that affect towing pin performance, what impacts can occur if the towing pin is not optimal, and the towing pin optimization strategy. The research method used is qualitative. This study uses the SWOT method (Strength, Weakness, Opportunity, and Threat). The results showed that the factors that caused the towing pin performance were not optimal due to several factors, including not optimal selenoid valve, dirty filters, mud in the towing pin gap, leaks or blocked hydraulic pipes, dirt in hydraulic oil, availability of spare parts, and human resources error. Advice that can be given is to anticipate internal and external factors that affect the performance of the towing pin in order to reduce or avoid the impacts that occur, learn how to handle components related to the towing pin directly and carry out regular and scheduled system maintenance plans for hydraulic components, the towing pin is prone to damage.
