It is hard to deny that the demand and need for more energy is growing at a rapid pace on a global scale. As a result of this, throughout the past couple of decades, different methods and solutions have been deployed to crack energy supply challenges. Especially renewable energy sources, such as wind power and solar energy, stands out as ways to reduce the impact fossil fuels have on global warming.

Most maritime infrastructure projects are required to undergo vigorous environmental and cultural or social impact assessments before being given the green light to be implemented. These evaluations look out for evidence demonstrating avoidance, minimisation or mitigation of impacts in the preparation, actual construction and post-construction phases.
We ask Juan C. Savioli, Head of the Coastal and Estuarine Department in our office in Malaysia, six questions on ‘Working with Nature’ and whether it is possible to integrate this concept into marine infrastructure designs. Continue reading “Myth or Fact? The concept of ‘Working with Nature’ for maritime infrastructure projects”
It is without question that the effects of human-derived underwater noise on marine life are receiving increased attention from scientists, regulators and the public. One of the core issues is the displacement of marine life from important areas due to behavioural responses to underwater noise from shipping, airguns and pile driving. Another issue is the impairment of hearing, which can be temporary (temporary threshold shift, TTS) or permanent (permanent threshold shift, PTS). Both effects can, at least in theory, lead to population-wide impacts to marine species. Continue reading “Agent-based modelling: Dynamic mapping of the movements of marine life”
It is a well-known fact that accidental oil spills can cause significant negative impacts on the environment – affecting ecosystems, bringing distress to marine life, damaging waterways, ruining infrastructure and economy, to name a few.
The 2010 Deep Water Horizon oil spill in the coastal waters of the Gulf of Mexico – often cited as the worst environmental disaster in the United States – saw up to 800,000 bird mortalities and approximately 60% decline in the number of laughing gulls along the Gulf coast between 2010 and 2013. Demands are therefore being placed on oil companies, service providers and environmental authorities to be prepared to take proper and efficient action, should an accident occur.

Compliance with regulatory requirements increasingly demands clear evidence on how birds behave within and around wind farms. To meet this demand, automated multi-sensor monitoring systems such as MUSE have been developed to provide robust data on real-life bird behaviour at and within wind farms. The MUSE system is based on integrated radar and digital camera(s) and was developed during a four-year pioneering investigation on seabird behaviour at offshore wind turbines; the Carbon Trust Bird Collision Avoidance Study 2014-2017.

Calculating wave impacts in ports and terminals
Operational safety is at stake when wave movement is high in ports and terminals. As such, port authorities and key stakeholders are concerned with wave conditions affecting vessel motions to avoid costly consequences. In addition, high vessel motions may damage mooring lines, fenders, or even the moored vessels in the port. What if there was a faster, better and easier way to model waves in ports as compared to existing methods? Continue reading “What are the constraints of traditional numerical modelling?”
Celebrating the power of wind
Thanks to global efforts and agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) in tackling climate change, we are observing a boom in renewable energy growth, especially in wind energy. Continue reading “Global Wind Day: How do wind turbines work?”
Accidental oil spills remind us of the dramatic impacts that oil can have on the environment. They also bring into focus the importance of efficient emergency planning. Continue reading “Accidental oil spills giving you a headache? It’s time to plan ahead”
Aquaculture is a booming business all over the world, but it is heavily dependent on ambient aquatic conditions.
Sustainable aquaculture requires innovative solutions in order to meet the challenges of nature.
So what’s the secret to being successful in this industry?

New dynamic mooring analysis tool allows even better planning of port layout
A port planner knows that the efficiency of a terminal could already be decided during early port planning stages – just by looking at predicted vessel motions. There’s a way to do so even more efficiently as I will describe below. In the initial planning process, all kinds of dynamic impacts should be included into the picture.
