Marine data is a valuable resource for marine engineers, but it can also be overwhelming and complex. How can you manage, analyze, and visualize the data you collect from the ocean, ships, and other marine systems? In this article, you will learn some tips and tools to help you make sense of marine data and use it to improve your engineering projects.
The first step to making sense of marine data is to collect it in an efficient and reliable way. You need to choose the right sensors, instruments, and platforms to measure the variables you are interested in, such as temperature, salinity, currents, waves, wind, pressure, and so on. You also need to ensure that your data collection methods are consistent, accurate, and compatible with the standards and formats of your industry or organization. For example, you can use the International Hydrographic Organization (IHO) standards for hydrographic data or the World Meteorological Organization (WMO) standards for meteorological data. You can also use software tools like QGIS or ArcGIS to manage and organize your spatial data.

Segregate and integrate key data types is vital. Vessel Performance- fuel consumption, engine performance, speed, efficiency- optimized operations and fuel usage. Navigation- routes, positions, and navigational hazards-ensures safe and efficient navigation. Weather-wind speed, direction, wave height, weather forecasts - for route planning and safety. Sensors- monitoring the condition of equipment and the environment. Maintenance- schedules, repairs, and spare parts usage for vessel maintenance and reliability Environmental-water quality, pollution levels, and marine life for environmental impact, compliance. Cargo-loading,carriage, unloading- handling, stability,safety. Compliance-Port, flag, class, vetting. Personnel- skills stcw.
Not only the right sensors but also knowing and understanding where, what and how the sensors measure the data. These are important factors that impact the ability to utilise the data properly later on. Without context a value is just a value and not data.
It's better to be selective early when selecting the data sample points. Ensure an even spread amongst industry peers and best practices. Avoid sampling only the "bottom of the barrel" or worst-case scenario.

Once you have collected your data, you need to clean and preprocess it before you can analyze it. Cleaning data means removing or correcting any errors, outliers, duplicates, or missing values that might affect your results. Preprocessing data means transforming or scaling it to make it easier to work with or to apply certain methods or algorithms. For example, you might need to normalize, standardize, or discretize your data depending on your objectives and assumptions. You can use software tools like Excel, R, or Python to perform these tasks. You can also use libraries like pandas, numpy, or scikit-learn to manipulate and process your data in Python.
Cleaning data is often the most time and labour intensive job to get going in the right way. Aligning various sources to timestamps, sampling times and quality takes time. Cleaning and pre-processing should be done preferably in an automated manner. Data pre-processing onboard a vessel before transmission is a powerful tool to reduce data traffic and optimize the use of data storage.
Cleaning and preprocessing data are vital steps after collection to ensure accurate and meaningful analysis. Cleaning involves the removal or correction of errors, outliers, duplicates, or missing values that could impact results.

Normalization, standardization, or discretization may be necessary depending on objectives and assumptions. Software tools like Excel, R, or Python are commonly used for these tasks. Python libraries such as pandas, numpy, or scikit-learn provide powerful tools for manipulating and processing data, offering flexibility and efficiency in the data cleaning and preprocessing phases.
The marine environment can be pretty rough, with all sorts of disturbances. You've got turbulent sea flow, sharp waves, high-velocity marine currents, and even speedy winds. It's no surprise that we end up collecting a bunch of noisy data that needs some serious filtering and cleaning. Luckily, there are a few methods we can use to get rid of that noise, like the trusty Kalman Filter. Now, let's talk about time – it's a super important factor in data collection. When we're preprocessing the data, we've got to make sure we know the exact time each piece of data was collected. This is especially crucial when we're dealing with different data collected at various sampling points. We need to synchronize everything so we can compare it properly.

Data cleaning in marine energy research should be minimal to preserve natural variability. Over-processing can remove critical insights. Emphasize robust collection and advanced analysis over heavy data manipulation to maintain data integrity.
The next step to making sense of marine data is to analyze and model it to extract useful information and insights. You need to choose the right techniques and methods to answer your research questions or solve your engineering problems. For example, you might use descriptive statistics, exploratory data analysis, or data visualization to summarize and understand your data. You might also use inferential statistics, hypothesis testing, or confidence intervals to draw conclusions and make decisions based on your data. You might also use machine learning, artificial intelligence, or optimization to build predictive or prescriptive models based on your data. You can use software tools like SPSS, MATLAB, or Python to perform these tasks. You can also use libraries like matplotlib, seaborn, or plotly to create and customize your data visualizations in Python.
To analyse data efficiently, one must understand the science behind why it’s there in the first place. And the more the experienced minds involved, the better the understanding.

In marine engineering, analyzing and modeling data is paramount for understanding the complexities of oceanic systems. Engineers employ various techniques to interpret data collected from sensors, satellites, and other sources. By developing sophisticated models, they can simulate ocean behaviors, such as currents, wave patterns, and sediment transport. These analyses provide insights crucial for designing offshore structures, optimizing shipping routes, and predicting environmental impacts. Additionally, advanced modeling allows engineers to assess the effectiveness of marine conservation efforts and adapt infrastructure to changing ocean conditions.
When it comes to data analysis, marine engineering is all about harnessing the incredible power of Fourier transform to switch things up from time to frequency domain. It's a game-changer! Imagine trying to analyze wave data spanning 50 years using traditional methods – it would be a never-ending task, if not downright impossible. But by diving into the frequency domain, we can make things a whole lot easier. We can simply focus on analyzing various wave frequencies and we've captured the essence of wave energy over those 50 years.
