Shipbuilding industry is awesome.. Technical drawing: the universal language of shipyards

Across shipyards around the world, vessels are built that differ in size, purpose and level of complexity. Although design processes take place in different countries and cultural environments, they are all united by one common code of communication – the technical drawing.

For engineers and designers, it is the primary working tool. A Polish shipbuilder may struggle to hold a conversation with a colleague from South Korea, Qatar or Brazil. Yet the moment both of them look at a drawing, all language barriers disappear. Technical documentation becomes a universal language, where lines, symbols and projections replace words.

From “the Line” to a global standard

- Every student of naval architecture, marine engineering, mechanics or mechatronics learns technical drawing from day one – and this standard holds true everywhere in the world. And it’s not just theory; everyone must learn to draw by hand, reminds Marcin Ryngwelski, CEO of PGZ Naval Shipyard.

Older generations will remember the subject under its former name – Descriptive Geometry, informally called simply “The Line”. Demanding and unforgiving, it was a true test of precision and patience. Professors would have students redo the same drawing multiple times until absolute accuracy was achieved.

Thousands of drawings – one ship

Designing a vessel means working through hundreds, often thousands of drawings. The documentation covers everything from initial concept sketches to detailed production plans. Before any blueprint reaches the production hall, it undergoes rigorous verification and a multi-stage approval process. It’s this discipline that ensures every finished ship meets the highest standards of quality and safety.

A shared technical language of the industry

- Any drawing created by a Polish or Korean shipyard design office is perfectly understandable to both sides, regardless of native language. If our shipyard received documentation from international partners today, we could immediately begin calculations and production planning – because the standards are unified globally, emphasizes the CEO of PGZ Naval Shipyard.

This standardization enables seamless international collaboration. Polish shipyards frequently work on projects developed by foreign design offices. Thanks to the universal language of technical drawing, such contracts progress smoothly – unaffected by linguistic or cultural differences.

Series: Shipbuilding industry is awesome

This article is part of Daily Mare’s series showcasing the world of Polish shipyards. We offer an inside look at the everyday work of engineers and designers, the tools they rely on and the strategic importance of the shipbuilding industry for national security and the economy. The series draws inspiration from the insights and observations of Marcin Ryngwelski, CEO of PGZ Naval Shipyard.
