Euan Fenelon Lauren Wheatley demand more flexibility; where interaction between generators, system and network With the demise of subsidy driven the industry needs to keep pace. operators becomes more sophisticated; economics, the industry has focussed on and where intelligent management of becoming much more pro-active.

The ControlCentre now employs 19 staff and manages 5 GW of renewable energy capacity comprising onshore and offshore wind, biomass, solar and hydro. This investment ensures the ControlCentre complies with all the new EU cybersecurity rules to protect clients’ assets and the grid, keeping them safe against potential cyber-attacks, as well as exploring new ways of increasing revenue for our clients. So how does it work? Site data arrives at ControlCentre and is analysed by our state of the art software, utilising machine learning techniques, to ensure the turbines are operating at peak performance. Whilst

COMMENT: FINANCEBlustery winds onshore inLatin AmericaWords: Julyana Yokota, Director, S&P Global Ratings. S&P Global Ratings rated its first onshore wind project in 2003. Since then, the renewable energy sector has undergone tremendous expansion. In the past decade alone, its compound annual growth rate has totalled 20%, thanks largely to the rising awareness of how using fossil fuels for power generation contributes to climate change.Julyana Yokota throughout the wind turbine supply chain, expand in regions outside of Europe both of which are fostering onshore wind – notably into the U.S. and Latin AmericaIn Latin America in particular, where most power’s rapid development. – will be key for maintaining a balancerenewable capacity comes from large hydro between growth and profitability.plants, onshore wind power sources are However, the sector’s growth isn’t withoutplaying an increasingly important role. serious challenges.

ASK THE EXPERTSWorldwide tailor madechartering solutions Mads Poulsen, Sales and Chartering Manager, BBC Chartering, Esbjerg, got together with PES to share his optimism on the outlook for the wind industry. He also talks about working with the bigger and bigger component sizes we are seeing today. Their worldwide offices mean they are more than well positioned to meet their customers’ needs.

For BBC Chartering to remain a leading player for wind in the future will require that we continue to listen to our customers and adapt to the challenges presented by the market and the industry. We´re confident that wind turbine components will require transportation in the future, too, and that BBC Chartering will stay at the forefront of these developments. PES: What is the single biggest challenge facing the market today? MP: Component sizes and bigger turbines are quickly limiting the capacity of suitable tonnage. Dialogues between manufacturers and carriers are required to ensure future fleets consider the industry’s transport needs. There is a risk that suitable capacity for the wind power sector tightens quicker than we anticipate which may cause substantially higher freight rates for the industry and poorer capacity efficiency for the carriers. www.bbc-chartering.com22 PES Wind

TALKING POINTThe first set of vessels are 38,6m long and10m wide, when we started the project theywere only 29m, but more and more thingshad to be fitted on board. This means thecraft are bigger than current CTVs. We havedecided to call them FSC39, Fast SupplyCatamaran 39m.We have been working together with Ørstedon the design of these vessels, and themain requirements from that side was toget vessels that can stay offshore for longerperiods of time, without taking on fuel fromother vessels, and which can operate in thedifficult sea conditions, when working somuch further offshore.There has also been a focus on lowmaintenance, which has resulted in a veryhigh spec propulsion packet, with CumminsKTA38 main engines, which can produce upto 1,500 hp, but in the continuous ratingdecided on by MHO&Co A/S, they are onlyattaining 1,000hp. This gives more than twiceas many hours between services as theIntermittent rated, or D-rated main enginesused in most crew boats. A definite plus.The requirement to carry more cargo, andto do so safely, can be seen on the vessels,including such features as guard rails allaround the cargo deck, to landing cargosafely on the deck.Due to the much longer water line, thecomfort on board is also much better thanon traditional CTVs this is very importantwhen transporting personnel that have todo a full day’s work and more, after theyhave been transferred to the work location.In today market not many CTV’s can carry www.peswind.com 33

This conversion process initially took about ten minutes to perform. In 2017, the company enhanced the design and construction of the gangway system to enable improved time savings. Following further innovation, an adaptable E1000 gangway was developed with an automated system which employs remote-controlled hydraulic pin pushers to fixate the gangway booms in less than one minute with a single button. The system can safely transfer people and up to 1,000 kilogrammes of cargo in rough sea waters.
