Software

Caution

This page is a work in progress. This should be a list of the preferred way of performing analysis, to ensure consistency and we are using software we are confident in.

General structures

SPACEGASS

Overview

SPACE GASS is used for general structural modelling software with only one main window. It can input a variety of loads such as pressure loads, moving loads, sea loads and many more. It can also be used to model plates for an FEA analysis and extracting moments strips.

Interface

Tips and tricks

Steel Member Capacity

SPACE GASS has functions to model steel members to automatically calculate steel capacites and utilisations!

Watch out: SPACE GASS does not calculate the utilisation for circular steel sections (such as piles) properly as it does not take the resultant moment and does a typical bi-axial bending check.

Concrete Design

Although not commonly used, SPACE GASS has functions to also do concrete design.

Plate Elements

KBR is able to model plate elements for an FEA analysis.

Watch out: KBR has only 2 licenses for plate elements so be considerate when analysing plate elements, don’t hold them if not actively using.

STAAD pro

Overview

STAAD PRO is a software for performing structural analysis and design. It features a streamlined workflow shown in the toolbar across the top of the screen.

Tips and tricks

Analysing Model

Simply creating your model, adding properties, materials, and loads will not let Staad Pro analyse your model. You will need to add the following code to your model analysis.

Units

To change the systems units, simply right click anywhere within the ‘Whole Structure’ tab -> Display Options -> Structure Units, Section Units, and Force Units.

Design Checks

You can also complete your design checks in Staad Pro, in the design tab, you can select the relevant code, then specify design parameters such as deflection, “DFF.” You will need to add the “Check Code” command beforehand. The results of this design check will appear in the output file, this can be found after running your analysis, before continuing to Postprocessing.

OAYSYS ADSEC

Overview

AdSec is used for evaluating the performance of a reinforced concrete section under different loading conditions.

Tips and tricks

Sign Convention

Horizontal axis is labelled y, and is positive to the right. Vertical axis is labelled z, positive upwards. Fx is axial load is positive for compression. Myy is the moment about the y axis, positive for compression on the top of the section. Mzz is the moment about the z axis, positive for compression on the right of the section.

Connections

IDEA STATICA

Overview

IDEA STATICA is a FEA connection modelling software for both steel and baseplate connections.

Tips and tricks

Use Templates

IDEA STATICA can be tricky and time consuming to model from scratch if you don’t know what you are doing. IDEA STATICA has a lot of example models online, just google what you are looking for and download a template.

Failed Baseplate?

A lot of the times IDEA STATICA will have failed your concrete design. IDEA STATICA has a very conservative method of calculating baseplate capacities so you should use another program (such as HILTI PROFIS) or a hand calculation to confirm your answers.

FEA

Strand7

Overview

Strand7 is a comprehensive finite element analysis (FEA) software package for structural and heat transfer analysis, used for engineering simulation and design. It features an integrated environment for building models, running analyses, and viewing results, with solvers for linear, nonlinear, static, and dynamic problems. The software is tightly integrated with the Windows environment and offers advanced features like geometry import/export, automatic meshing, and a flexible user interface for tasks like multi-model analysis and custom settings.

Interface

Tips and tricks

Model in CAD

As STRAND7 can be tricky to model, it can be much easier to model everything in AUTOCAD 2D as surfaces, then import them into STRAND7 and then mesh it after.

Mooring analysis

OPTIMOOR

Overview

OPTIMOOR is an easy-to-use mooring analysis computer program for use by vessel and terminal personnel as well as by port designers and naval architects. It is based on the Oil Companies International Marine Forum (OCIMF) recommendations and procedures and includes OCIMF wind and current coefficients for tanker and gas carrier (prismatic / moss) vessels.

Tips and tricks

Finding Information

A lot of OPTIMOOR is finding the correct places to find information for all your inputs. Ensure that you have looked through the:

• Functional Design Brief for:
  • Vessel parameters
• Drawings for:
  • Bollard locations, fender locations, wharf shielding.
• Vessel datasheets for:
  • Everything vessel related and,
  • Mooring line parameters
