Ever wondered how a Bollard Pull Test is performed? 309.6 tonnes of pure force. Watch and learn...as our ALP tugs practice their craft. bit.ly/2hBozBH #bollardpulltest #alpstriker
Tug I used to work on was a steam tug, 17 tonne pull. I massive amount of labour was taken to sustain that pull too! Two boilers & 6 furnaces to stoke, the crew of 15 was seldom idle. During the annual harbour "tug race" we were quite happy to be cruising at 15kts in light swell and nil wind holding a stead 180psi of steam. We were quickly overtaken by the harbours newest tug - going astern no less - at quite a pace. Those modern voith propulsion systems are amazing in the amount of power they deliver and the maneuverability!
You seafarers are a very special kind of people with the heart where the sea is. I heard the above several times. Like: It's hard at times but I wish I could go again.
Was involved with a Bollard test years ago. A sudden engine surge ripped the Samson post off the deck an threw it 500m through the air. It was found a week later on another dock.
We've done bollard test on the Port of Jebel Ali during the early 1980's. The vessels are GC 306 , 7 and 8 . They're all powered Cats and Mirless Blackstones. We've done both the pull and side thrusters. By the way GC stands for Gulf Cobla ( costain / blakenvoort ). The company built the Jebel Ali port. Watching your video brings back a lot of good memories in Dubai. The GC vessels are split hopper barges all built in the Netherlands just like I'll make a guess here Alp Striker is . This video is taken some where in South Korea I would also guess. And in Korea I remember one have to leave ones shoes outside the door if you enter one of those very welcoming houses. Good luck guys, Von Voyages.
I need help to solve a problem, I have to find a way to calculate the maximum bollard load that I use here at the shipyard. Does anyone have any ideas?
I've always wondered about these DP2 vessels that have 2x bow thrusters of small size plus a retractable azimuth thruster in the bow. It gives great station-keeping in normal situations, but in the event of a worst case failure the vessel would be reduced to a single small bow thruster. With 2x 1500kw thrust in the bow it should have great redundancy.
Depends on where the hawser is attached on the ship. As you can see in the video, its almost amidships. If it was in the stern it would be much harder to keep the ship straight.
I just watched another video...that led me here that said it would take approximately 80 of these to produce enough force to pull the Ever Given out of it's position.
@@justingarret4776 wtf are you talking about. They just waited for the right moment of NATURE and pulled the evergiven out. Avoid those conspiracy theory channels mate 😎
I know nothing about ships, this was in my suggested, I have no idea what’s going on... video says it’s a tug but it appears to be flooring it while attached to a land anchor???? I do not understand why there is a land anchor or why this beautiful ship is giving it a tuggy tug....
It's a bollard pull test, it's a test to measure how strong the towing capacity of a ship is. This ship pulls the anchor point with a force of more than 300 tonns.
It's an inverted bow, more specific a x-bow. Traditionally ship designers tried to stay on top of waves. inverted bows dive through waves, trying to keep the ship at a constant level. This obviously requires much better protection against waves at the front, but also offers much better speeds and comport.
Then the Dutchman who was telling us about his boat, put his joint down an staggered away to sleep it off! Heard Ducks fart, seen the bubbles! Big claims, no proof.
Cool boat, Dudes. However, you somewhat lost the chance for a narrative when you had not narration. The titles were informative, but, I don' know, somebody telling us a few facts and figures would have been nice.
