Naval Architecture and Vessel Design
Every vessel begins as a set of constraints: displacement, draft, intended service, and the waters she will navigate. Our role is to resolve those constraints into a hull form that performs with precision across its operational envelope. We work from first principles: hydrodynamic analysis, structural loading calculations, and classification society requirements from the outset.
Hull Form Engineering
Shipwrights.com commissions Computational Fluid Dynamics (CFD) modelling at the preliminary design stage, not as a late-stage validation exercise. CFD analysis optimises hull resistance, propeller-hull interaction, and wave-making characteristics before steel is cut. This reduces fuel consumption across the vessel's operational profile and contributes directly to IMO Energy Efficiency Design Index (EEDI) compliance.
Structural Design and Classification
Every structural member is specified to meet the scantling requirements of the appointed classification society. We coordinate with IACS member societies, including Lloyd's Register, DNV, Bureau Veritas, and others, from concept stage through to plan approval. Finite Element Analysis (FEA) is applied to critical structural nodes including engine foundations, crane pedestals, and high-stress hull transitions.

Regulatory and Environmental Standards
All design work accounts for current IMO environmental regulations. MARPOL Annex VI sets emission limits for sulphur oxides (SOx) and nitrogen oxides (NOx) across designated Emission Control Areas. The EEDI framework requires progressively lower carbon intensity for new builds entering service. Our design specifications incorporate these requirements from the general arrangement stage, preventing costly retrofits during construction or after delivery.
Frequently Asked Questions
What classification societies does Shipwrights work with?
We coordinate with all IACS member societies, including Lloyd's Register, DNV, Bureau Veritas, American Bureau of Shipping (ABS), and RINA. The choice of classification society depends on the vessel's intended flag state, trading area, and owner preference. We manage the plan approval and survey coordination process from initial design submission through to the issuance of class certificates.
How does CFD modelling reduce operational costs?
Computational Fluid Dynamics modelling analyses hull resistance and propeller efficiency at the design stage, before construction begins. Optimising the hull form for the vessel's intended speed and loading conditions reduces fuel consumption across her operational profile. On a medium-range commercial vessel, CFD-optimised hull design can reduce fuel expenditure by 8 to 15 per cent compared to a conventionally faired hull.
