The world of maritime engineering is fast-moving, and integrating navigational automation and safety systems has become integral to any build.
The advent of navigational automation is currently revolutionizing maritime operations. This technology aims to reduce human error, enhance safety, and improve efficiency.
“Traditional navigation relies heavily on human expertise,” explains maritime engineering expert Sian Yang Tan. “While this is invaluable, human error remains a significant risk factor. Automation can help mitigate these risks by providing precise, reliable, consistent performance.”
Navigational automation in maritime engineering uses advanced technology to enhance safety and efficiency by reducing human error.
Autopilot systems automatically control the ship’s steering to maintain a set course with minimal human intervention.
An example is GPS and GNSS, which provide precise location data, enabling ships to determine their exact position and follow pre-defined routes.
Radar and lidar can detect obstacles and other vessels to prevent collisions and navigate safely through crowded or challenging environments.
Tan also mentions Artificial Intelligence (AI) and Machine Learning (ML): “It can process navigational data in real time to predict navigation, optimize routes, and adapt to changing conditions.”
“The Electronic Chart Display and Information System (ECDIS) integrates navigation information into a single display, providing a comprehensive overview of the ship’s position and route. Collision avoidance systems use radar and lidar data to predict potential collisions and automatically take evasive actions.”
Tan is undoubtedly at the forefront of this revolution, pioneering systems that are setting new standards for the industry.
He is a renowned expert whose work in enhancing maritime safety and efficiency: “Navigational automation is as much about saving lives and protecting the environment as the introduction of technology,” Tan asserts.
He started his career in the Singapore shipyards as a management trainee at Keppel Fels Pte Ltd and advanced to Construction Manager. He managed large-scale unconventional projects, oversaw budgets, proposed cost-effective solutions, and managed workflow and workforce.
He was then awarded the opportunity to study for a Bachelor’s in Naval Architecture and Offshore Engineering (Honors) at Strathclyde University, Glasgow.
Tan has also earned a Master of Science in Business Analytics and an MBA from Hult International Business School.
I get a huge thrill from seeing big projects come to life and actually float on the water; it’s a major motivator for me,” says Tan.
“I also love working with a team of passionate people to create something functional and innovative. That’s such a crucial part of ship and offshore design.”
Tan has been involved in several notable projects, including navigational automation. Many were while he worked at the PaxOcean Zhoushan Shipyard in Zhoushan, China.
Renowned for shipbuilding, offshore fabrication, conversions, retrofits, repairs, and maintenance, it has large graving docks and extensive facilities for various projects.
He also worked on the Raisa – a submersible barge designed for drilling barge and specialized maritime operations.
It features significant dimensions, submersion capability for loading cargo, high deadweight capacity, and advanced ballasting systems.
Tan says one key benefit of navigational automation is its enhanced precision and reliability: “Automated systems use advanced algorithms and real-time data to ensure accurate navigation, even in the most challenging conditions.”
“Automation eliminates guesswork,” Tan states. “It provides precise data that helps ships navigate safely through congested waters, adverse weather, and other challenging scenarios.”
These systems can process vast amounts of data from various sources, including GPS, radar, and sonar, to make real-time adjustments: “It’s like having an experienced navigator on duty 24/7,” Tan notes. “The level of accuracy and reliability is unparalleled,” he adds.
There is another reason Tan wants to see more automation used: human error: “It is a leading cause of maritime accidents,” he reveals.
“Fatigue, stress, and environmental factors can impair a crew’s performance, leading to mistakes that can have catastrophic consequences. Of course, human error is inevitable,” Tan acknowledges. “But with automation, we can significantly reduce the likelihood of such errors.”
“Automated systems can handle routine tasks, allowing the crew to focus on critical decision-making and oversight. “Automation supports the crew,” Tan explains.
“It doesn’t replace them but enhances their capabilities, ensuring safer operations.”
Tan says collision avoidance is another critical aspect of maritime safety: “Traditional systems rely on manual inputs and visual observations, which can be prone to errors.
“AI-driven systems can analyze patterns and predict potential collisions with high accuracy,” Tan says.
“They can take proactive measures to avoid dangerous situations, such as altering the ship’s course or speed.”
These advanced systems provide an additional layer of safety, particularly in busy shipping lanes and during poor visibility conditions.
“In congested waters, every second counts,” Tan emphasizes. “Automated collision avoidance systems provide the necessary speed and accuracy to prevent accidents.”
While navigational automation offers numerous benefits, Tan stresses the importance of integrating these systems with human oversight. “Automation should complement human expertise, not replace it,” he asserts. “The best results come from a harmonious blend of technology and human judgment.”
Tan advocates for comprehensive training programs that equip maritime professionals with the skills to effectively use and oversee automated systems. “Training is crucial,” he says. “Mariners must understand how these systems work and how to respond if something goes wrong.”
Navigational automation also plays a vital role in protecting the marine environment. By optimizing routes and reducing fuel consumption, automated systems help minimize the environmental footprint of shipping operations.
“Efficient navigation means less fuel burned,” Tan explains. “This translates to lower emissions and a smaller carbon footprint.”
Tan’s work includes working with systems that monitor and control emissions, ensuring compliance with environmental regulations: “Sustainability is a core consideration,” he says. “Automated systems help us operate in an environmentally sustainable manner.”
Advanced automation systems have real-time sensors that monitor a ship’s environmental impact.
These systems can detect and respond to oil spills, discharge violations, and other environmental hazards. “Real-time monitoring allows for immediate action,” Tan notes. “We can mitigate environmental damage before it becomes a major issue.”
Bilagi Thangavelu has worked with Tan for two years at Seatirum AmFELS, on the 15,000CY hopper dredge barge project.
Thangavelu served as the Commissioning Manager, while Tan was the Project Manager:” His deep understanding of marine engineering and project execution preceded him. Observing his management style and technical insights firsthand quickly reinforced his strong professional standing.
“Sian Yang has always been supportive and collaborative. For example, during the testing and commissioning phase of the hopper dredge barge, Sian was instrumental in troubleshooting technical issues and providing the necessary resources and support to ensure successful completion.
“His ability to monitor and control project progress, ensure quality delivery, and maintain the project within budget was remarkable and demonstrated his exceptional project oversight capabilities.”
He adds: “One significant challenge we faced was ensuring the seamless integration of new proto-type systems during the commissioning phase of the hopper dredge barge. Sian Yang’s strategic planning, effective communication with stakeholders, and technical problem-solving were crucial in overcoming these challenges and ensuring the project’s success.”
Tan is optimistic about the continued evolution of navigational automation. He envisions a maritime industry where autonomous ships are commonplace, operating with minimal human intervention while maintaining the highest safety standards: “Autonomous ships are the next frontier,” Tan predicts. “They will revolutionize maritime operations, making them safer and more efficient than ever before.”
However, Tan cautions that this future requires careful planning and collaboration across the industry. “We need robust regulations and standards,” he stresses. “Collaboration between engineers, regulators, and operators is essential to ensure that autonomous systems are safe and reliable.
”Collaboration and understanding between the client and builder are also crucial,” he says.
“Both parties must be flexible and communicate effectively to achieve the best outcomes.”
Tan’s expertise in navigational automation and safety is driving significant advancements in maritime engineering and setting new standards for the industry. Thanks to his relentless dedication to innovation and excellence, his vision for a future where autonomous ships operate safely and efficiently is ambitious and achievable.
“Navigational automation is the key to a safer, more sustainable maritime industry,” Tan concludes.
“By harnessing the power of technology and integrating it with human expertise, we can create a future where maritime operations are both efficient and environmentally responsible.”
