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.

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

The wind industry presents specific challenges when dealing with tool operator injuries. Because of remote locations and hazardous working conditions, it can often take hours for help to arrive once an injury occurs. Safety needs to be considered in every aspect of the job. Hand Injuries: costly in many ways Hand injuries, in particular, can be not only devastating to a worker, but also costly to a project budget. Worker compensation claims for hand injuries average around $7,500 per injury. The Bureau of Labor Statistics cites that approximately 110,000 hand injuries result in lost time. Hand injuries send more than 1,000,000 workers to the emergency room each year. The construction industry requires the tightening of approximately 30,000 bolts per year, so if not done properly, the chance for hand and finger injuries is significant. In the construction industry alone, the annual cost of hand cuts and punctures is around $400 million. When dealing with wind tower construction and maintenance specifically, these injuries most often include bruises, cuts, abrasions, punctures, fractures, and even amputations.

In Europe today, it is standard to equip newly built wind turbines with service lifts. These allow technicians easy access to all levels of the tower. Many older turbines do not have this advantage and require operations and maintenance personnel to ladder climb instead. On such wind farms, there are countless soft tissue injuries due to the repetitive motion of climbing. These injuries lead to sick days, reduced motivation and can stress the operation efficiency of the project. 3S Lift offers specialized retrofit solutions for existing turbines that allow technicians to ascend towers more quickly and protect their health against the strain put on the body by climbing. This way, they can reach the top rested and start their work right away. Over the last 20 years, 3S Lift has become a leading global wind turbine tower internals (WTTI) solution provider. With locations in China, India, Europe and the US, the company supplies a wide range of products to wind turbine manufacturers, tower manufacturers, service providers and wind farm owners across more than 40 countries. Retrofitting existing wind turbines with these solutions can add considerable value, improving both, health & safety and economic performance. That’s why a number of large developers are
