Spares in Motion (SIM) has a solution for wind energy O&M pitfalls. Reducing costs and obtaining spare parts as needed is increasingly important, especially as uptime demands skyrocket and maintenance contracts end. SIM explains to PES how their database is facilitating these goals for owners and operators today. We are a nearly half way through 2020 and thought it would be interesting to ask ourselves, what are some notable themes we are seeing in Renewable Energy? Among others, these interesting trends take center stage on a global scale today: • There is an industry-wide effort to reduce O&M costs • Not only that, but we see an aging installed base - increasing the lifetime of wind assets • Furthermore, high uptime demand has operators looking to reduce down time through proactive maintenance and stock management. By traditional design, these 3 trends are not always complimentary to one another, yet owners and operators are working to find holistic solutions to satisfy each.

Ports display the economic growth engines in the economy of countries. Increased activity requires larger ports, capable of handling a larger volume of traffic representing buoyant import-export balances. However, the epitome of ports also presents the consumables of natural resources, represented by the goods moving over the quay side. It could be argued that ports have an obligation to be the pacesetter for sustainable development, given that they are both instrumental and a longstanding economic driver. Marsh to modern urbanity On the West coast of Denmark lies Port Esbjerg, which was inaugurated in 1868 and therefore is a young generation port compared to other major European ports, which date back to the middle ages. Ports have evolved over centuries and must be considered in the context of the progression of the industries they support, whilst also recognizing that a port, its industry and society are intertwined. Development has been progressive at Port Esbjerg. It has created a resource base and infrastructure, which support change when compared to other ports. The multifaceted types of cargo and operations conducted in here portray a myriad of markets allowing for resilience. Even so the question must be asked: are the vicinity’s actors, stakeholders or implementors facilitating this

There is a green revolution in ship technology going on these days. We are currently witnessing a wave of zero emission propulsion ideas entering the market like battery powered car ferries for short routes, power shaving batteries onboard offshore hybrid service vessels and cruise liners that can enter protected fjords purely on batteries. Such efforts are fine for the local environment, but will hardly contribute significantly to bring down the CO2 emission of the global shipping fleet by 50% within 2050 as is the goal of the International Maritime Organisation (IMO). There is a strong push from the public as well as governments, industries and NGOs in support of the UN’s sustainable goals to counter the threats to our planet caused by the global warming. This development is just in the beginning and is strongly supported by class societies and maritime administrations such as DNV GL, Lloyds Register, Bureau Veritas, Korean Register, Royal Society etc. Serious discussions and development work are taking place pointing to the opportunity of changing the future fuel from fossil fuels, typically characterized as hydrocarbon chemical compounds of CyHx, to hydrogen rich compounds without carbon.

The concept ‘vessel intake’ is at the forefront of windmill component design, and it will make possible more profitable logistics projects when different variables are considered under a collaborative approach. The wind industry is facing a never-ending pressure on costs. All industry players, including first and second-tier suppliers, are developing different initiatives around cost reduction. As it happens today, logistics could be the last barrier in the automotive, or the food & beverage industries, but to overcome such a barrier, it is essential to implement a new and different approach. Reducing logistics costs is something that almost all companies aim to do, and we all know that simply lowering costs is not a good long-term strategy. So what do we have left? We need initiatives that bring a broader and more efficient strategic vision of the entire logistics chain. We should bear in mind that the transport of this type of component not only includes sea transport, but also land transport, different storage facilities, and all the necessary operations. At this moment, in the current market, there are different initiatives to seek productive improvements, but only on a few occasions are the logistics considered. So, in general terms, logistics projects that

Assessments and analyses for lifetime extension of wind turbines There’s a sizeable wave rolling in towards the wind energy industry: this year, in Europe alone, more than ten percent of installed capacity will be reaching its 20th year of operation, and by 2025, the figure will be almost 30 percent. To keep them running or not, this is the question faced by more and more operators who are thinking about lifetime extensions for their turbines that go beyond the end of their 20-year design life. With the constant annual growth in the number of renewable energy systems installed worldwide, there comes an increase in the average age of turbines in operation. Taking technical development into account, this now includes turbines up to the performance area of one or two megawatts, which are gradually coming to the end of their design life. For many of these turbines, experience shows that they can continue being operated safely and economically, even after they reach the end of their planned service life. There are several possible options: repowering, lifetime extension, sale or even dismantling the entire turbine.

In the search for alternative ways to make foundation installations quieter, faster and easier, the offshore vibro driving technology has developed in leaps and bounds over the past 20 years. The ever-increasing demand for reducing the Levelised Cost of Energy (LCOE) and protecting the underwater wildlife, has triggered out of the box thinking for the foundation pile installation. The origin of vibro driving on land goes back to the 1930’s. It became more common offshore about 20 years ago, when onshore vibro hammers were used to install relatively small piles. Since then the largest land vibro hammers have been used occasionally, sometimes combining several of them for larger diameters or when more power was required. The current record is ‘piles’ with a diameter of 30 metres, driven with a multiple linked vibro in China! After entering the offshore market with vibro hammers back in 2008, CAPE Holland developed a multiple vibro for the first ever monopile for a WTG in 2012. In the German exclusive zone, the monopiles for the Riffgat Offshore Wind Farm were driven to a stable depth, without noise mitigation before they were driven to their final depth with an impact hammer, due to the strict German regulations. The

W2W market maturing at last It’s clear that the Walk to Work (W2W) concept is here to stay in both wind energy and the oil and gas industry. The major operators and turbine EPCs have all commissioned dedicated W2W vessels from various operators. The last 4 years has seen a number of new operators enter the market with different vessel designs and improved gangway designs. Now the question is who can deliver the required performance most effectively? PES turned to BMO Offshore for their thoughts. The current situation is not unlike that of the crew transfer vessel (CTV) market of 10 years ago. It’s quite interesting to see the development of this new market in the light of the experiences of the CTV market. CTVs were the genesis of the dedicated offshore wind vessels, and after an initial development phase, there was a substantial boom. At this time the market was flooded with new operators with exciting designs ranging from mono hull, catamaran, trimaran to Swath and surface effect Vessel. Lessons learned on vessel performance It was, however, quickly realized by many, that performance of the vessels was vastly different at different locations throughout Europe. Carbon Trust, in the UK, and others undertook substantial
