3:35 i'll be honest im more concerned about the notion of a ship being built in such a way that a single water tight door being left open can sink a ship ... i mean if nothing else 1 no two compartments flooding alone should be able to sink your ship .. if it can you need more and smaller compartments and 2 i would hope there at least enough pumping capacity on your ship to be able to match the flow that could conceivable come through an opening the size of one water tight door
2:26 honestly i would have just assumed they were interlocked such that you cant open up the next one until the one behind you has been closed and or a timer
The major problem with the kind of thinking demonstrated in this video is the assumption that everyone knows what they are doing, have received full training and retained all the information they were given during that training. That is simply unrealistic and unobtainable and ignores several basic human and societal realities which are: 1 People are stupid, say, do and perform stupid acts with out thought or consideration 2 People are incompetent 3 People are lazy 4 People and especially groups of people, are disorganised and shambolic. When 1, 2, 3 and 4 are taken into consideration the ideals in this video are a total nonsense especially around the expectations in this video that all the crew will know what they are doing. MOST IMPORTANTLY - when 1, 2, 3 and 4 are taken into consideration with respect to any training the crew may be given, the problem is twice as bad. The training will not be full, complete and very probably, not given by somebody qualified to train anybody else anyway because they themselves were never properly trained. The most dangerous aspect to the design philosophy in this video is the operation of these doors with human interaction. The doors will not be kept closed because of the annoyance this creates. But of course no ship operator is going to admit to that because of the productivity costs associated with the massive delays opening and closing these doors constantly will incur. So, like the door designers, they just lie and pretend the doors are being operated correctly and kept closed while at sea. Because if the worst happens and the ship ends up on the bottom, whose ever going to know half a dozen doors were open when it wend down.
I dotn think people appreciate the strength of power actuated watertight doors especially when they slam closed in a emergency they can kill and they have killed and seriously injured,
I've always been really anal about holding onto the handles while going through. Saw one slip with a crewmate few years ago and activate while he was going through. Scared the shit out of me.
They did the issue with the titanic was that too many compartments where breached and the water tight compartments did not extend high enough - the water ended up flowing over the top to the next compartmetn as that part of the ship was pulled down by the extra weight of the water.
When I was at sea in the 1970s we did pretty much as the video says. However, our chain was held in place by a "pelican hook", which was released with a sledge hammer. No mention of that here. Are pelican hooks still in use?
For 6 years I worked for a company that collected metal from the ocean floor for recycling and we got more anchors and miles of enormous chain off the ocean floor, one time we were sent to get cars where a ship sank ,we brought up over 200 u.s. muscle cars someone bought and was taking to Italy all were 60,s and 70,s cars. Some really rare. Salt water had ruined the engines I'm sure, you could rebuild them but it would take mass money, most of what we went af was for insurance company's that had paid for the loss already and wanted to actually make sure that they had paid for the right thing, we brought one ship up that the owner had collected the insurance money for and when we got it up and went aboard it was totally stripped inside, the owner had even took the huge engines apart and took em out before sinking it, then said he was out and it sank I'm sure hes probably in prison cause he collected a few million on that one and the insurance company came and took pictures and the coast guard made reports of it all as insurance fraud , the owner had it happen 2 times in 1 year so we brought the second one up so they could make sure the owner wasn't lying, and he was
the cargo boat business is one of the 'dirtiest'..,too many crooks are running these companies..zero boat maintenance ,unpaid salaries ,pollution ...this needs to change...
So bottom line is poor maintenance, incompetent training, and use of poorly manufactured chains/ parts. It's pretty straigtforward to fix all 3 of those issues.
Great video to watch I have always wondered about how and why dropping anchor goes wrong I have a question still why don't people wear simple dust masks to keep from inhaling any of the fine particles of rust ?
You wouldn't believe how many weekend sailboat captains get the anchorage wrong. Most are used to just tying up to a dock and don't have proper knowledge of how to anchor out. Most people think you just drop the anchor and when it hits bottom you're done. They don't know about the chain/rode length ratio and "common sense" won't help them learn it without something being damaged. That's why most wannabe sailors should attend sailing classes to learn these things and other important issues that deal with boating!
