Skibsdesign

Skibsdesign, or naval architecture in Danish terminology, is the discipline responsible for planning ships and other seafaring vessels. It encompasses hull form, propulsion, stability, strength, and overall performance, integrating scientific and engineering considerations to meet intended use and regulatory requirements.

The field evolved from wooden sailing ships to iron and steel hulls, and later to steam, diesel, and gas turbine propulsion. Advances in hydrodynamics, materials science, and construction methods shaped hull shapes, weight distribution, and structural concepts. In the modern era, design also addresses containerization, offshore platforms, and environmental performance.

Key design areas include hull form and resistance prediction, stability and cargo handling, propulsion and power systems, structural scantlings, and machinery layout. Designers balance speed, range, safety, crew comfort, and maintenance with cost, manufacturability, and regulatory constraints. Naval architects also consider reliability, ease of inspection, and lifecycle performance.

The design process typically proceeds from concept to preliminary design, then detailed design and production drawings. Tools used include CAD software, computational fluid dynamics (CFD), finite element analysis (FEA), and model testing in towing tanks or cavitation rigs, to validate performance and safety before construction.

Compliance with international rules and classification society standards guides safety and environmental performance. Organizations such as SOLAS, MARPOL, and classification societies like Lloyd’s Register and DNV GL shape requirements. Naval architects collaborate with shipyards, owners, flag authorities, and insurers to certify vessels and prepare construction documentation.
