Surma combat survivability

SURMA APPROACH TO PHYSICS

SURMA Analysis Tools use well-validated and practically streamlined physical models to make the assessments fast and accurate. This makes it possible to integrate the survivability analysis into the iterative design process and allows designers to constantly improve and validate the design without added costs induced by late design changes.

ACCORDING TO YOUR NEEDS

SURMA is built onto the idea that you can have and use only the tools you need, but it also provides the possibility to use external tools via built-in interfaces. All SURMA Analysis Modules and Interfaces are used and managed through the SURMA Core, which is prerequisite for all SURMA Software Products. 

SURMA SOFTWARE CAPABILITIES

• Import and use the ship's design model
• Create and edit ballistic protections
• Create and import routes, equipment, systems and structures
• Create and edit threat scenarios
• Run analysis with SURMA Analysis modules    
  
  

THE BENEFITS

• No unnecessary modelling         
• Built-in parameter libraries         
• Custom parameters to define any scenario         
• Based on real physics         
• Seamless integration with common tools and workflows         

SURMA UNDEX

SURMA UNDEX is a very fast and automized physics-based vulnerability assessment tool, which takes into account the hull plating damage from the shock wave, the global kickoff velocity of the ship hull, and whipping response to gas bubble pulsation.

The hull plating damage is assessed using an advanced time-domain based SDOF model, taking into account the initial shock wave, and local and bulk cavitation.

SURMA AIREX

SURMA AIREX is very fast and automized physics-based vulnerability assessment tool for SURMA. It takes into account the damage from fragments, air blast and flooding.             

Structural response and system failures are analyzed. For systems, redundancies in the system tree and route failures are included in the analysis.

SURMA MG

The ship’s ferromagnetic materials and parts cause an anomaly to the earth magnetic field surrounding the ship. This anomaly is called the magnetic signature of the ship. The signature can be detected with magnetometers in a sea mine and a mine can be triggered to detonate when a ship passes by.

SURMA Magnetic modelling offers capability for very fast static magnetic signature assessments. Results are available already at early design stages.  

Perhaps the most challenging part of any analysis and assessment is the presentation of results in intuitive, transparent and unambiguous way. SURMA Report provides the designer with valuable information that can be used to improve the design throughout the process from the early sketches to lifetime upgrades.

FINDING THE WEAK SPOTS

In order to enhance the design based on the conducted survivability assessment, SURMA relies heavily on graphical representations and sortable tables and lists regarding the assessment results. The hyperlinks connect the different entities to each other, e.g. a compartment is connected to all of the equipment  components it contains. This makes it easy to navigate the results and track the details within the SURMA model.

A clear understanding of the big picture is crucial, if the aim is to find improvable issues in the overall design. With this kind of interactive and informative graphics the user is quickly able to get an overview of the assessed scenario.                        

LEAVING THE PAPER – 3D        

The biggest differentiator between SURMA Report and a traditional report is probably the third dimension. The use of HTML format enables the integration of conventional static report and interactive 3D-graphics without requiring any additional software.
