MAXSURF Naval Architecture Software Developers of Maxsurf, FormSys, recently acquired by Bentley to form part of an enhanced marine and offshore portfolio. MAXSURF Naval Architecture Software Peter Newlands Director of Island Computer Systems Ltd

MAXSURF Overview Integrated suite of naval architecture applications Common 3D model for all applications Change flows through from model to analysis Consistent, modern, graphical UI across all apps Easy to learn and pick up and use Full coverage of all naval architecture functions Maxsurf is a suite of applications for all aspects of naval architecture

Applications for all Naval Architecture functions All work from a common 3D NURB model: All of the applications work from a common 3D NURB surface model. This helps naval architects

MAXSURF Applications Modeler Stability Resistance Motions Structure 3D Surface modelling Stability Stability and strength Resistance Wake and Power Prediction Motions Motions prediction The specific modules within the Maxsurf suite Structure Initial structural design Multiframe Structural Strength Analysis

MAXSURF Modeler Dynamic trimmed NURB surface modeling of any vessel Also has round trip interoperability with Rhino and Microstation

MAXSURF Modeler: Hull Modeling Dynamic 3D NURB surfaces with trimming Intuitive graphical user interface Import/Export of existing designs (Rhino, MicroStation, AutoCAD) Matching of target hydrostatic parameters Versions Basic Modeler – 20 surfaces Advanced Modeler – Unlimited

MAXSURF Stability Intact and Damage stability and criteria compliance Comprehensive analysis of stability of any vessel or floating structure. Includes intact and damaged stability and assessment of compliance with stability criteria from IMO and others. Includes stability in waves and with grounding.

MAXSURF Stability: Intact & Damaged Stability Hydrostatics, Stability, Strength Stability Criteria MODU, IMO, SOLAS, custom Automation scripting Damage Stability, Grounding, Stability in Waves Versions Basic Intact, no tanks Advanced Intact and damaged Enterprise Probabilistic damage

MAXSURF Motions Prediction of vessel motions using strip theory. Good for motions predictions of FPSOs and other ship-shaped vessels. Fast and easy for proposal work, note however that it is not (yet) not a full motions package like Moses, Seasam or AQWA.

MAXSURF Motions: Motions Prediction Inputs Maxsurf Model, Remote Locations Multiple Headings, Speeds, Sea States Output Response Amplitude Operators Motion sickness Index Time Series Animation Validated against tank testing Versions Basic – Strip Theory Advanced – Adds Panel method See slides .. To .. For more details on Seakeeper.

MAXSURF Resistance: Wake and Power Prediction Prediction of resistance and wavemaking Prediction of power requirements of vessels. Either based on regression analysis of tank test data or a CFD potential flow code built in. Also good for predicting the wake created by a vessel.

MAXSURF Resistance Regression analysis methods Analytical methods Planing (Savitsky, Blount and Fox, Lahtiharju) General (Holtrop) Trawlers and Tugs (van Oortmerssen) Semi displacement (Compton, Fung) Cargo (Series 60) Yachts (Delft Series) Analytical methods Slender Body Method Free Surface Wave Pattern

MAXSURF Structure: Initial Structural Design Define parts by point and click Definition of fair shell stiffeners Parametric structure model responds to design changes Develop plates Graphical display Strain, Stretch, templates Export functions Parts to Microstation, AutoCAD, ShipConstructor, Rhino and others Export to Multiframe for structural analysis Versions Basic – Plate development Advanced – Stringer layout, frame and deck definition

Multiframe: Structural Analysis Motions induced, Lifting, installation, stiffened plate analysis Structural analysis specific to vessels and offshore installation projects. Special load cases and analysis modes for motion induced loads, hydrostatic and buoyancy loads,

Multiframe: Motions-Induced Analysis Automated calculation of motions-induced inertial loads Linear and angular accelerations Automatic correction for mass location Optional self weight Versions Basic 3D static Advanced Adds Dynamics
