Marine
From the design and manufacture of small recreational crafts and large oil tankers to the most technologically advanced aircraft carriers, Altair has assisted the world’s leading shipbuilders and boat designers to develop higher performing, safer and lower cost vessels through the application of simulation technology. Altair helps naval architects address complex engineering challenges and mitigate environmental risks associated with seagoing loads including structural, hydro, dynamic, thermal and fatigue, as well as above surface and underwater weapon threats for the military and homeland security.
Simulation for Safer Sailing
Simulation assists the engineering of safer marine vessels and robust offshore structures with modeling of collision, sloshing, slamming, underwater explosive, structural strength assessment, vibration, noise performance, heat and cooling analyses, as well as antenna design. It is important to ensure designs meet industry classification and society regulations, capture knowledge and increase development efficiency through customization and automation technologies and expertise.
Reduce Total Ownership Cost
Increased global competition requires a faster and more efficient ship design and certification process to shorten the turnaround time and reduce cost. To stay competitive in the global marketplace, shipbuilders are looking for ways to reduce production and lifecycle maintenance costs. Increase design efficiency and minimize material usage to reduce manufacturing and operational cost, all while increasing fuel efficiency with Altair’s leading structural and computation fluid dynamics (CFD) optimization technologies.
Tools for Naval Architects
Robust Commercial Ships: Altair® OptiStruct®, includes an enhanced proprietary version of NASTRAN that is used in virtually every industry. OptiStruct provides solvers for linear, nonlinear, vibrations, acoustics, fatigue, heat transfer, and multiphysics analyses. Building upon the solver capabilities of OptiStruct, Altair® HyperLife® provides a comprehensive and easy to use durability analysis workflow directly interfacing with major finite element analysis result files. OptiStruct is the original topology optimization structural design tool.
Ready Military Vessels: Altair® Radioss® multiphysics capabilities accurately simulate complex physics problems, such as collision, sloshing, slamming and underwater explosions. Altair® Feko® is the global market leader for antenna placement analysis. It is widely used in naval engineering for most electromagnetic issues, like radiation pattern analysis of communication antennas, the placement of antennas, antenna coupling/interference, and near-field radiation hazards. Additionally, WRAP™, an Altair® Feko™ component, enables safe and secure communications for vessels at sea, ensuring there are no blind spots in coastal waters resulting from interference or missing coverage.
Faster Recreational Boats: Based on the Finite Element Method, Altair CFD™ is a robust and scalable general-purpose CFD solver that empowers users by providing unparalleled accuracy on fully unstructured meshes. OptiStruct is widely used at the world’s most innovative companies for the design and optimization of laminate composites . It delivers optimal ply shapes, the optimal number of plies, and the optimal stacking sequence, all while observing manufacturing constraints.

Tailored Solutions
Custom Software: Tailored and automated simulation workflow processes for evaluating specific requirements and events can accelerate a more robust engineering process for shipbuilders. Altair’s Product Engineering Services team has extensive experience working with top shipyards and classification societies to assist them in developing packaged solution offerings, integrating both commercial and proprietary tools, to consistently evaluate and streamline certification processes.
Automation for Shipbuilding: The Altair Crane CAE Manager is a new process solution for evaluating and improving the block assembly method of ship building, where cross-sections of the superstructure are pre-built, taken to the building dock, and hoisted into position and attached. It uses a set of macros to assist engineers in dockyards sequence for the block assembly of ships. Parametric system-level models use OptiStruct and Altair® MotionSolve® to generate results and Altair® HyperStudy® enables system performance optimization.

Improving Rudder Shock Loading Following a Nearby Blast Event Using Radioss
Engineers in the Marine, Shipbuilding, and Offshore industries face many design challenges including physical space constraints, extreme weather conditions, deep water and remote locations. These constraints create an extreme environment for the engineer to develop a sound, reliable and safe operating platform.
Creating a Structurally Efficient Design for the Queen Elizabeth Class Aircraft Carrier
When making key decisions at the concept and preliminary design phases of a naval ship project, the designer is often obliged to work with limited data on the major structural design drivers for the vessel. This can lead to a largely subjective design approach which can result in inefficiency and even structural problems being locked-in from the start. To solve any issues, increased material use, weight and unnecessary complexity, as well as high design and manufacture costs can be introduced to the end product. To evaluate the potential of simulation-driven design under the unique requirements of naval ship design, the ACA partnered with Altair ProductDesign.
Taking on the Shell XPRIZE with Help from a Digital Twin
Chris Wilkinson, CTO at SMD speaks at the UK Altair Technology Conference 2019. An XPRIZE challenge is designed to source new approaches to solve difficult problems thereby disrupting existing markets or creating new ones. Our oceans cover over 70% of the planet with only 5% explored. The ocean environment is hostile and technically challenging to operate within. The Ocean Discovery XPRIZE competition was established to seek cheaper and faster solutions to survey the world’s oceans. This presentation is about one of the teams that entered the competition with a disruptive solution for ocean survey. The emerging role and importance of a digital twin is explored to support the solution as it scales from proof of concept to one that is fully industrialised.
