Moving Ahead Powerfully
The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.
CFD Simulation of a Fully Featured Offshore Platform Model
CFD simulations of offshore oil and gas platforms are used to predict the maximum wind loads acting on the structure of the platform topsides (the upper half of the platform, above sea level and outside the splash zone, including the oil production plant, the accommodation block and any drilling equipment). The wind loads are used as waves and current loads to design the mooring of the structure, and can be significant in specific ocean areas. Because platform topside geometries were traditionally considered too complex to mesh in high detail…
Product Lifecycle Management for Shipbuilding
Tomorrow’s high tech fleets will depend on shipyards – long after the christening is over. Siemens PLM software makes that dream possible – today. According to global powerhouse Siemens, a major transformation is underway in the marine sector. As operators strive to develop more energy-efficient, reliable and environmentally friendly vessels that also lower operating costs, they will increasingly depend on shipyards to make that happen. That’s right: shipyards. Long after the vessel slides into the water and the christening party is but a distant memory, the clean and efficient workboat of tomorrow will leverage a wealth of data that the builder will manage. Before any of that happens, shipbuilders will also need to design and build ships faster and better than ever before.
New LMS 3D Simulation Offers Real-world Tech
LMS, recently acquired by Siemens and now a business segment within Siemens PLM Software, announced the latest release of its LMS 3D solutions for real world simulation, LMS Virtual. Lab Rev 12 and SAMCEF Rev 15. Both software releases use innovative technology to simulate real-world behavior for faster, more realistic and easier product design. Every LMS 3D simulation solution can be tailored to precise industry and application requirements in areas such as acoustics and vibration, mechanisms, automotive and aerospace simulation process integration, structural analysis and wind turbine development. The latest releases of the two core LMS 3D simulation software suites, LMS Virtual.Lab and SAMCEF including CAESAM, address several of the industries’ most pressing engineering challenges.
Siemens Highlights Sustainable Shipping at Workboat
