The Trend


  1. Sustainability

Shipping Industry is one of the main contributors to the global emissions, currently estimated at around 3% of global total.  This is why shipping has come in the crosshair of demands for greater efficiency.  In COP26, there will be focus on discussing ways to reduce emissions.  No surprise that Sustainability is the biggest trend affecting marine industry. Ship designers and builders will definitely face increasing pressure to reduce environmental Impact. Traditional design methods rely on scale model testing and/or model scale CFD simulations. These cannot deliver the level of improvement required in the short timeframes set by governing bodies.

  1. Global Competition

In marine industry history, we are aware of the up and down cyclical behaviour.  When the industry is at the downcycle, ship owners and operators are looking to invest in most cost effective vessels.  This means shipyard must compete harder than ever before to develop and build ships with lower total lifecycle costs (both CAPEX and OPEX), higher operational availability and shorter time to market.

  1. Increasing demand for high value-added vessels

We are seeing an increasing demand for high value-added vessels, multi-role or muti-purpose vessels (especially in the naval, mega yachts and offshore markets), and a growing interest in autonomous shipping (especially in the commercial and naval sectors.)

Therefore ships today are more complex than ever before:

  • More complex equipment and systems onboard
  • More electrical systems: more sensors, cables etc.
  • More parties involved and more information manage and communicate
  • Workforce needs to continuously adapt and embrace new technologies


Digital transformation is the key to mastering today’s challenges and unleashing innovation.   The possibility of Digital Twin relies on the practical solution to help customers leverage digital twin across the entire lifecycle (Product Digital Twin, Production Digital Twin and Performance Digital Twin). Siemens’ Xcelerator Portfolio is enabling, driving and managing the whole digital framework.

Systems Performance and Controls

The marine industry is facing huge challenges in reducing fuel consumption and pollution. Simcenter can help ship builders to build high performance, eco-friendly powertrain systems, including electrification and hybridization.

Simcenter enables analysis throughout the design process, from multi-system architecture creation to systems and component design, system integration and control strategy validation. From the earliest stages of the development cycle, designers can analyse model results to reach the ideal architecture for minimum fuel consumption and NOx emissions.

Building a virtual, integrated model means users can check what impact their system architecture choices will have on the entire vessel, before any physical development takes place, and helps naval architects and other marine experts make the right decisions on vessel energy balance, achieving a win-win situation for them.

Engines and Power Generation

As humans we are land-based, so often we do not realize the huge impact the marine industry has in our lives. At any one time there are 100,000 ships at sea, of all shapes and sizes. With our increased awareness of the environmental costs of transport, the marine industry faces the challenge of meeting strict emissions regulations over the coming years. The Simcenter portfolio is uniquely positioned to help with this.

With a combined and complementary adoption of testing and advanced simulation, users can efficiently evaluate interactions when integrating subsystems such as the engine, electric generator, power electronics and cooling systems, leading to more efficient overall operation.

The Simcenter portfolio offers the unique possibility to improve many critical performance areas, such as electrical generator and motor design and energy consumption, efficient cooling systems, optimized batteries, NVH for on-board machinery, fatigue and durability of individual components or complete systems, and passenger comfort and crew health
