Abstract
South Africa faces challenges in optimising power-distribution equipment systems within its naval architecture and ocean engineering sectors. A comparative study employing a quasi-experimental design was conducted. The study compared two groups: one with traditional systems and another with advanced systems, measuring yield improvements over time using statistical analysis. Significant differences were observed in the output efficiency between the two groups (p < 0.05). The quasi-experimental design successfully identified yield improvement trends; however, further empirical testing is recommended to validate these findings. Pilot studies should be conducted on a larger scale before full-scale implementation of advanced power-distribution equipment systems in South Africa's naval architecture and ocean engineering sectors.
