Early Works Start for First Taiwan-built Offshore Installation Vessel

accommodate a crew of up to 160 people," CDWE said.The vessel will feature dual-fuel engines and will have a Green Passport and Clean Design notation. Furthermore, ‘Green Jade’ will have a waste heat recovery system that converts heat from the exhaust gases and cooling water to electrical energy, in addition to various other fuel-saving measures."This is a historic moment in Taiwan’s offshore wind development and indeed for the Taiwanese shipbuilding sector, as this dedicated offshore installation vessel is the first of its kind to be built in Taiwan for the local renewables

the activity of the heart or brain, or to help with touchscreen technologies on medical devices or cellphones. He said the TENG innovation also has applications for virtual and augmented reality technologies, as the Purdue innovation can detect body movement and turn the mechanical energy into electrical energy.The team worked with the Purdue Research Foundation Office of Technology Commercialization to patent the technology. The office recently moved into the Convergence Center for Innovation and Collaboration in Discovery Park District, adjacent to the Purdue campus.The creators are looking for

power, which can improve reliability at sea by ensuring continuous power supply.The Maersk Cape Town includes a waste heat recovery system, which is a special feature of many Maersk container vessels. This system increases overall efficiency, as it allows the batteries to charge by capturing electrical energy from heat that would otherwise have been lost out of the exhaust gas system for the main propulsion.“This exciting pilot – the first of its kind in the industry - will show the potential of battery technologies to keep improving the performance of our vessels while also reducing

Stretch for Power: High-tech Yarn Generates New Energy

way to think of twistron harvesters is, you have a piece of yarn, you stretch it, and out comes electricity," said Carter Haines, a lead author of the study published in the journal Science.   The device, which exploits the ability of nanotubes to transfer spring-like motion into electrical energy, has numerous possible applications, according to the paper.   In the lab, tests showed that a yarn weighing less than a housefly could light up a small LED light.   When sewed into a t-shirt, it could power breathing sensors - like those used to monitor babies - using the stretch

2010, he started at DFKI and was involved in various robotics projects. In 2013, he moved to business development and helped establish a Brazilian Institute of Robotics and a Brazilian robotics company. Over the past 5 years he has developed over $30 million in research projects in the oil and gas, electrical energy and mining sectors. He was also responsible for client relations and served as the main contact point with BG/Shell for the FlatFish subsea resident AUV project.

Wave Energy's Power Play

progressing as a viable source of renewable energy, and recently that progress has accelerated. One of the companies leading wave power’s advancement is New Jersey based Ocean Power Technologies (OPT), considered a pioneer in the arena with more than 20 years’ experience in generating electrical energy from waves. With its PowerBuoy system, the company has shifted its focus from larger scale power generation to a more targeted, and importantly, survivable and reliable product.   The wave power sector has encountered its share of challenges over the years.

Bureau Veritas Develops Rules for Diving Support Units

;The rule note addresses the requirements specific to units supporting professional diving including the installation of the diving plant on-board, the interface between the ship and the diving system and the description of the in-service surveys. Among the main issues dealt with are fire safety, electrical energy supply, emergency means of escape, communication means and storage of the oxygen used to enrich the breathing gas.” The latest industry practices are adopted including IMCA recommendations regarding diving.  

AXYS WindSentinel Floating LiDAR for EDP Inovação’s Demowfloat Project

and gathers 12 entities of 5 different countries who aim to test and monitor the performance of their floating wind turbine. The prototype, located 6km off the Portuguese shore, enables wind power to be harnessed at sea in deep water (depths greater than 40 m) for conversion to clean renewable electrical energy. The AXYS WindSentinel is scheduled for deployment in late summer as part of the ongoing validation program for the Demowfloat initiative. “We are extremely proud to have been chosen by the EDPi team to work on this groundbreaking initiative aimed at significantly reducing the cost

in freezing temperatures. It is likely that this trend will continue, particularly for arctic and environmentally sensitive areas where offsets of up to 500 km have been envisioned. And when these systems need pumps and compressors to increase recovery they will require large amounts of electrical energy to be transferred and controlled from shore. Investing in the subsea vision However, transferring energy over such distances with acceptable losses is in itself a challenge. To solve some of the challenges ABB and Statoil recently entered a joint industrial program (JIP), that entails
