The logo features a bold and structured circular design with multiple layers, giving it a dynamic and prestigious appearance.

At its core, a vibrant yellow circle serves as the backdrop for a striking red "S" emblem, which is accentuated with a subtle 3D effect. Surrounding this is a blue ring that adds contrast and depth.

The outermost metallic silver-green ring contains the acronym "PSTC" in a classic serif font, along with small lifebuoy icons evenly spaced around it, reinforcing a maritime or safety-related theme.

A flowing green ribbon elegantly overlays the lower portion, displaying "35th Emerald Anniversary" in bold, stylized typography, creating a celebratory and formal touch. The years "1983 – 2018" are placed at the bottom in a simple yet clear font, reinforcing the milestone.

The overall composition is balanced and visually engaging, combining traditional and modern design elements to convey a sense of legacy and achievement.
