DNV Nauticus Machinery 2026 v16

DNV Nauticus Machinery

DNV Nauticus Machinery is a specialized software suite within DNV’s comprehensive Nauticus design platform, dedicated to the rule-based design, analysis, and documentation of marine machinery systems. It is not a general-purpose CAD or simulation tool, but an authoritative calculation system that automates and validates designs against DNV’s and other major classification societies’ rules (IACS members). Its primary purpose is to ensure machinery systems—from main engines and propulsion trains to pumps and piping—are designed safely, efficiently, and in full compliance with mandatory international regulations and class requirements, streamlining the approval process.

Primary Users

Nauticus Machinery is essential for professionals in marine machinery engineering:

• Ship Design & Consulting Engineers performing mandatory rule-based calculations for classification approval.

• Classification Society Engineers at DNV, and other IACS members, reviewing and approving vessel machinery systems.

• Propulsion System Engineers designing and analyzing shaft lines, bearings, and propulsion arrangements.

• Engine & Equipment Manufacturers (Wärtsilä, MAN, ABB) ensuring their products comply with classification rules.

• Shipyard Engineering Departments for newbuild design and retrofit projects across all vessel types (tankers, bulkers, offshore, cruise).

• Naval Architects needing integrated machinery analysis within the overall ship design.

Key Features & Capabilities

Rule-Based Calculation Modules

• Shaft Alignment & Vibration Analysis: Comprehensive analysis of complete shafting systems, including:

  • Torsional Vibration: Critical analysis for engine and gearbox selection, ensuring avoidance of resonant frequencies.

  • Lateral Vibration: Analysis of whirling and critical speeds for shafts and propellers.

  • Axial Vibration: For specific configurations like CP propellers.

  • Steady-state Alignment: Calculation of bearing loads and shaft deflections under operational conditions.

• Engine & Power Plant Analysis: Tools for evaluating derating, load analysis, and compliance with emission control areas (ECA) regulations.

• Piping System Analysis: Rule-based calculations for pipe wall thickness, stress, and flexibility according to DNV, ISO, and ASME standards.

Integrated Design & Approval Workflow

• Direct Rule Integration: Software database is updated quarterly with the latest DNV Rules and relevant IMO regulations (MARPOL, SOLAS). Calculations reference specific rule paragraphs in outputs.

• Template-Based Projects: Pre-configured templates for standard vessel types (e.g., “Aframax Tanker,” “LNG Carrier,” “Offshore Supply Vessel”) to jump-start projects.

• Automated Report Generation: Produces draft calculation reports formatted for class submission, including all assumptions, input data, and references to applied rules.

• 3D Integration: Interfaces with CAD systems (CATIA, NX, Aveva Marine) to import geometry for analysis and export results.

Specialized Analysis Tools

• Gear & Coupling Analysis: Assessment of marine gears, clutches, and couplings according to classification standards.

• Foundation & Bedplate Design: Analysis of engine and machinery foundations for static and dynamic loads.

• Noise & Vibration Prediction: Tools to predict airborne and structure-borne noise levels for habitability (CABIN notation) and environmental compliance.

What’s New in the Latest Release (2025)

The 2025 updates are tightly coupled with regulatory changes, digitalization, and sustainability:

1. Enhanced Carbon Intensity (CII & EEXI) Integration: New modules to directly calculate a vessel’s Energy Efficiency Existing Ship Index (EEXI) and simulate operational Carbon Intensity Indicator (CII) scores based on machinery configuration and power curves, aiding in retrofit decisions.

2. Alternative Fuel Readiness Analysis: Extended calculation libraries and rule sets for machinery systems using LNG, Methanol, Ammonia, Hydrogen, and biofuels, including fuel supply piping, ventilation, and safety analyses.

3. DNV Rules Update 2025: Full implementation of the latest DNV Rules for Ships and DNV Rules for Classification of Ships Pt.4 Ch.7 (Machinery Systems), ensuring immediate compliance for new designs.

4. Cloud-Enabled Collaboration (Nauticus Cloud Services): Selected calculation modules and project data can be shared and reviewed via DNV’s secure cloud platform, facilitating remote work and smoother communication with class surveyors.

5. AI-Assisted Input Validation: Machine learning checks input parameters against historical project data to flag potential outliers or unusual design choices before submission.

6. Extended Cybersecurity (CYBER) Notation Support: Tools to assess the cyber-resilience of integrated control systems (ICS) within the machinery plant, as per DNV’s new class notations.
