Nauticus Hull Rule Check package

This includes

Note that Nauticus Hull “classic” January 2018 (version 18.15) is not part of this installation package any longer, but can be downloaded separately.

Nauticus Hull FEA package

This includes the

and in addition the following program modules

Rulesets covered by Nauticus Hull January 2022 (v20.19):

DNV Rules for classification: Ships (RU-SHIP)
- All editions up to and including July 2021.
DNV Rules for classification: High speed and light craft (RU-HSLC)
- July 2019 Edition.
DNV Rules for classification: Offshore Units
- Support for prescriptive and FE calculations according to DNVGL-OS-C102 Structural design of offshore ship-shaped units up to and including July 2021, entering into force 1st January 2022.
IACS CSR BC & OT
- All editions from January 2015 including January 2021, enter into force on 1st July 2021.
- NOTE to Pt.1 Ch.8 Sec.4 Buckling requirements for Direct strength analysis: GeniE V 8.2 will be required to apply the rule changes for the FE buckling assessment.

The following rule sets are not covered by Nauticus Hull v20

These rules are supported by Nauticus Hull “Classic” January 2018 (separate installation).

New features

General, modelling

Parametric 2D-modelling introduced. Y/Z-grid positions and main particulars like B, D can be used in several modelling dialogues for geometry, plates and stiffeners where a coordinate is entered.
Filtering possibility added to workspace list, list of rule calculation files, stiffener profile list and end connection/shear connection list. The filter option will shorten the list to ease the selection of the proper item.
Modification of spacing between multiple longitudinal stiffeners is now possible.

Finite Element Assessment

FE Fatigue Tool: Low cycle fatigue assessment, as required for gas-fuelled container ships introduced
Local Model Load Applier (LMLA) Tool: For supports of independent tanks, contact forces represented as nodal forces in the cargo hold model can now be distributed as surface loads (lateral and traction) in the local model
Export to GeniE: Transverse bulkheads modelled in Nauticus Hull can be exported to GeniE

3D Beam

Tapered beam profiles: Users can create beam profiles with linearly varying cross-sectional dimensions along the length of the beam, that will be taken into account when computing stresses
