The engineering company INNAS and technology company Hydrautrans are developing a mechanical-hydraulic transmission for offshore wind turbines with a capacity of more than 12MW. The Floating Cup Technology used for the transmission is invented and patented by INNAS.The hydraulic pumps and motors operate without internal metal-to-metal contact.This translates into superior system efficiency without wear and results in an elongated service life of more than 25 years and an efficiency of more than 95%, the developers said.Preliminary calculations show that, by implementing this hydraulic transmission in new wind turbine models of existing suppliers, the levelized cost of energy (LCoE) can be reduced significantly, according to the developers.The low turbines price in combination with an elongated service life is said to result in a LCoE reduction up to EUR 6 per MWh.The 12MW transmission consists of four independent modules of 3MW each. The components are lightweight which leads to a 10-25% head mass reduction, according to the developers. Wind turbines with a lower capacity, either 6MW or 9MW, can also use this new technology by placing less modules, and the technology allows upscaling to over 12MW in the future.The expectation is that this technology will be released on the market by 2020.
National Shipping Company of Saudi Arabia (Bahri) has taken delivery of Shaden, a very large crude carrier (VLCC), from South Korean Hyundai Samho Heavy Industries (HSHI) shipyard. The 300,000 dwt ship is the fifth VLCC to join the Bahri fleet this year, following the deliveries of Amjad, Maharah, Aslaf and Rimthan.Flying the flag of Saudi Arabia, Shaden features a length of 330 meters and a width of 60 meters.Currently, the newbuilding has a market value of USD 81.39 million, according to data provided by VesselsValue.The newly received vessel is one of the five VLCCs financed by Riyad Bank, Bahri said.The commercial operation of Shaden is expected to begin in December 2017.Bahri’s fleet currently comprises 88 vessels including 41 VLCCs, 36 chemical/product tankers, six multipurpose vessels and five dry bulk carriers. In addition, the company has five VLCCs on order.The delivery of Shaden comes only days after Bahri released its financial results for the third quarter of this year which show that the company’s profit for the period dropped by 80.8 percent to SAR 60.5 million from SAR 315.3 million seen in the same quarter a year earlier.
ON Tuesday May 16, Guyana Chronicle told the distressing story of Guyana’s CARIFTA Games gold (3000m) and bronze (1500m) medallist Claudrice McKoy, who, despite the lack of basic daily necessities, including electricity, even though she lives in the capital, has been excelling in both track and academics.McKoy’s story is still trending, as calls mount for Government to put in place, some mechanism that will help our athletes, more so those who are needy.“Government would like to encourage all sports, (but) there’s no institution or mechanism examining persons who are talented but impoverished,” said President David Granger.Speaking exclusively with Chronicle Sport yesterday, the Head-of-State pointed out that while there’s “something that could be done on a case-by-case basis, there’s no programme for training and sponsoring impoverished athletes.”“Each case will be judged on its merit; we want to give every opportunity for talented people whether or not they are poor; we want to be well represented in the sports arena around the world,” President Granger explained.Meanwhile, McKoy’s principal, Henry Chase said that a donation of an undisclosed sum was made to the athlete on Tuesday.Chase handed McKoy a scholarship to his institution (Chase’s Academic Foundation), solely on her athletic ability. He also remarked that the 16-year-old was exceptional academically.McKoy is currently writing nine subjects at this year’s Caribbean Secondary Education Certificate (CSEC) examination and Chase is confident of the middle-distance athlete coming out on top.However, Chase said he only learnt of the student’s unfortunate situation after reading the article and said he felt compelled to help.“She’s humble, mannerly and does really well in school,” Chase said, adding “I had no idea of her struggle until I read the story, so I felt the need to step up and do something like I do for a number of my students, especially those who are here on scholarship.”
