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

Trojans outhit Hawai’i

first_imgThe USC men’s volleyball team is winning again.And boy does it feel good.Big performance · Junior opposite hitter Murphy Troy tied for the Trojans lead in both kills (16) and service aces (five) against Hawai’i last night at the Galen Center. USC has now won two straight matches. – Gary Fung | Daily Trojan “We’re starting to play a little bit. We’re looser out there and starting to have fun,” USC coach Bill Ferguson said. “We got our mojo back, as one of my assistants said.”For the first time since Jan. 22, when USC was 10-2 and No. 1 in the nation, the No. 7 Trojans won back-to-back games, as they avenged an earlier season loss to No. 8 Hawai’i 3-1 (16-30, 30-22, 30-19, 30-23).“This is exactly what we needed,” junior setter Riley McKibbin said. “It feels good. We’re finally starting to click.”The Trojans were led by a balanced passing attack from Riley McKibbin and his younger brother Maddison McKibbin. They kept the Warriors off balance all night, as three players had more than 20 kill attempts, not including both middle blockers, sophomore Steve Shandrick and senior Hunter Current, who had 16 attempts each.“When we pass well, I can run the offense,” Riley McKibbin said. “We have some of the best attackers in the league. It’s just about being able to run the system. I’ve been focusing on running the middle a little more, and it worked out real well for us.”It looked like the Trojans might be in for a long night after the first set. For the eighth time in their last nine matches, the Trojans lost the opening set.The Warriors outplayed the Trojans in almost every aspect, outhitting them .473 to .081 and winning 94 percent of their sideout points, compared to just 51 percent for USC. Ferguson put in three substitutes in late in the set, but more to get them playing experience and give McKibbin and the middle blockers rest so they could be ready to start the second set.“We were out of timeouts, so I just wanted to get them ready and gear up for the next three sets,” Ferguson said.And what did he tell them after the usual first set loss?“I told the team we had them right where we wanted them.”After that first set, the match flipped on its head. It seemed USC could do nothing wrong. The attackers varied the offense with floaters over the top of the blockers and kills around the side of the blocking wall. The Warriors had no answers for the Trojans’ attack, as USC ended up with a .357 hitting percentage.USC turned up the defensive pressure as well. After recording only one block in the first set, the Trojans finished with 15.“We’ve been blocking better in the last two months, it’s just been overshadowed by some of the losses,” Ferguson said. “I thought our guys did the best job of executing the game plan tonight and our serving was much better, making it more unpredictable.”Unlike in the match against UC Santa Barbara, USC built big leads early in the last three sets and didn’t let up. They jumped out to 16-9 leads in both the second and third sets and an early 4-0 lead in the fourth set.“We saw they were flustered, so we knew if we kept playing consistent they would crumble,” Riley McKibbin said.The Trojans hope they can repeat their performance tonight when they host Hawai’i again at 7 p.m. at the Galen Center.last_img read more


first_imgQuinn’s bar was closed for two days by the HSE.Dublin bar Quinn’s, regularly frequented by Donegal GAA supporters on match-days was closed down by the health service executive for two days.Quinn’s pub which is located in Drumcondra, is a popular watering hole for the legions of Donegal fans that descend to Dublin every summer to see Donegal play at Croke Park.With games against Armagh, Dublin and Kerry this summer Donegal fans had plenty of trips to the capital, and Quinn’s was the No.1 bar for the majority of Donegal GAA fans prior to the match due to it’s proximity to Croke Park. It would then be the first stop after the match for Donegal GAA fans left thirsty after watching their sides pulsating games at Croker.However, the pub’s closure was one of twelve that was ordered by the Food Safety Authority Ireland in September under rules that deem there to be “a grave and immediate danger to public health”.The closure order was served on Quinn’s under food safety legislation on Monday 8 September, the day after the drawn All Ireland hurling final between Kilkenny and Tipperary. It was lifted two days later.  BAR POPULAR WITH DONEGAL GAA FANS CLOSED BY HSE was last modified: October 8th, 2014 by Mark ForkerShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:closureCroke ParkdonegalGAAHSEnewsQuinn’s pub Drumcondralast_img read more
