MARIN, Deltares Test Transport & Installation of Gravity-Based Structures

first_imgDutch research institutes MARIN and Deltares have completed a test campaign focused on the transport and installation of gravity-based structures (GBS) as part of the GBS WIND Joint Industry Project (JIP) launched in March 2017.Image: MARIN/ Deltares (cropped)The two research institutes carried out the campaign to get a deeper insight into the motions of a gravity-based structure during transport and installation, which have not been well captured by standard design methods. In particular the nonlinear, viscous effects such as Vortex Induced Motion (VIM) and galloping have not been accurately computed, according to the researchers.During more than 14 weeks of testing, MARIN and Deltares were using three model basins and were able to consider the full operation from port to fully ballast on the seabed.“We have created a truly unique dataset which has given us a better understating of the dynamic behaviour of gravity based structures during transportation and installation. We have been able to investigate phenomena such as VIM during installation and to improve our numerical models. Previously this has not been possible to this level of detail,” said Dr. Bo Terp Paulsen, project manager Deltares.During the project’s next phase, improved numerical models will be used to drive the simulators at MARIN and tug captains will be able to practice critical moments of the transportation and installation phases, giving valuable feedback to the engineers and designers who can then optimise future foundations for stability and safe marine operations.last_img read more

Luke Walton doesn’t want Julius Randle, Larry Nance Jr. to rely on 3-point shots

But for both of them, they do other things so well. The ultimate end game for them can’t be them being stretch-fours who want to shoot 3s all night,” Walton said. “They’re too good, too athletic and too versatile. That’s just something to be able to fall back on late in the shot clock.”It does not appear Walton needs to worry. Though Randle and Nance have both shot only 25 percent from 3-point range over the past five games, neither has relied on the shot much. Randle has taken 44 shots in the past five games, eight from 3-point range.“I’m taking what the defense gives me,” Randle said. “I’m still being aggressive and attacking the basket and not just settling on my jump shot.”Over the same five games, only four of Nance’s 22 attempts were from 3-point range. LOS ANGELES >> As Julius Randle fired 3-point shots after recent shootarounds and practices, he heard Lakers associate coach Brian Shaw say a few biting words.“He kept calling me scared,” Randle said before Tuesday’s game against the Clippers at Staples Center. “I took it as a challenge.”Since then, Randle boasted that he and Lakers guard D’Angelo Russell have beaten coach Luke Walton and Shaw 7-1 in a 3-point shooting contest after recent morning shootarounds and practices.Like Randle, Lakers forward Larry Nance Jr. has spent time working on his 3-point shot in an effort to expand his game after hearing constant feedback in his past two seasons. “I’m not rushing it. I’m taking it as it comes,” Nance said. “I won’t be the first guy out there shooting it. I won’t take five or six 3s in one game. But if you leave me open, I’m going to hoist it. I feel pretty confident about it.”Walton said he might start Nance before the season ends in mid-April, either with Randle or starting center Ivica Zubac. Both players sounded fine with the possibility.Said Nance: “Whether you come off the bench or start, it’s not about who starts the game. It’s about who finishes.”Said Randle: “I don’t care. As long as I hoop.”Etched in penWith the Lakers eager to gather as much data as they can for evaluation purposes, they considered it more valuable to retain undrafted guard David Nwaba than to sign another player to a 10-day contract.“He gives us a toughness that we need. He gives us a defensive mindset that we definitely need,” Walton said. “He knows that’s what’s paying the bills for him right now. Having that type of personality right now we thought was valuable for our young group.”On Tuesday, the Lakers signed Nwaba to a two-year deal, including a team option for the 2017-18 season, according to a league source familiar with the terms. While Nwaba is guaranteed to be with the Lakers for their remaining 12 games of the 2016-17 season, the second year of his deal is non-guaranteed.“I’m very happy and excited for another chance to showcase my skills,” said Nwaba, who averaged 0.6 points and 2 rebounds while shooting 48.1 percent in 14.4 minutes through 10 games. “I’m glad they like what I’m doing even though it didn’t show too much on the stat sheet.”center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more
