COMMERCIAL DIVING | CAREER TIPS | Offshore CRANE Operations Subsea + BONUS Footage of Crane Failure!

hey guys welcome back to commercial diving FAQ where we talk about all things commercial diving in this video I'm going to be talking about crane ops subsea and how you can increase your safety factor and productivity levels in the water now I know most divers have an attention span of a goldfish so I'm going to try and keep it short and sweet I'm gonna pick as much information to it as possible at the start of this video but if you do stick around to the end I've got a small video that I want to show you of a crane failure offshore in India that I took where a crane actually dropped a pipe onto a material barge now fortunately no one was hurt but it's definitely worth the watch so stick around [Music] first it give them a distance bearing with the directional bearing for the crane so I want to slow write 5 meters now there's 3 reasons why I want to do this and all of them increase the safety factor of the movement the first reason is there is a mess of lag and communications especially when it comes down to the all stops now the communications go from the diver to the supervisor and then the supervisor has to swap radios and then radio the crane to make the movement and will give the oil stop so by giving the distance measurement it eliminates the need for that communication to happen before the crane actually stops where you want it to now the second reason is overshoot if the crane driver knows exactly how far to go then he is going to make that movement and then stop on his own accord and it should leave you roughly in the right place now if you were to give that distance measurement and he was waiting on your all stop you would give that all stop you would have that lag and communications to get to the crane driver and then he would stop but what would happen is the block takes a little bit to catch up to the boom so it would continue to move forward until eventually it caught up with the head of the bird and the final reason is stored energy stored energy is a bit of a hard one to pick up on but usually if you make a crane movement that block should eventually follow if you don't get any movement data your block although the crane is moving you might think that there's something going on the surface or they haven't made the move but really they are moving so if you give their distance measurement they will all stop at however fire you've told them it'll stop a continuation of you telling them slow right slow right slow right slow right and nothing happening before something snaps now the reasons why it could happen is a wire could be snagged up on a subsea structure you could have something tied back against the thing you're trying to lift without you realizing it or a few other reasons but you're really eliminating or reducing the amount of stored energy that you have net wire just in case it does get caught up the second tip I've got for you is to add shekels to the side of something flat that you're trying to lift now this is more for the topside guys and you may be using riggers but it's up to the divers to make sure that everything goes subsea is inspected by them before they go on before it goes in the water so if you're lifting something flat and you try and put it down on the seabed especially with just one diver you're gonna get float and that means it's gonna move around a little bit before it actually gets placed if you try to be specific in terms of the placement of this thing if you add shackles to one side of it to set it on an angle slightly you can touch down one point and then go to the other side and guide that down as well makes things like quicker a lot easier there's this fluffing around the water and it makes you look more professional now the third tip say industry-standard but I feel like it needs to be said here and it is illuminate everything put light sticks on absolutely everything from the crane hook to the work basket to whatever you're trying to lift to the down line to the the launch recovery basket it doesn't matter the better the more light sticks the better in the water now I know it's not efficient in terms of use of light sticks but it really it makes your job go so much quicker and easier when you've got light down there to see with now if you get any cranes sent down from the surface and low light conditions it's really hard to see and especially if you're tucked away in a safe area away from where the crane is actually coming down it can be nearly impossible to see when it gets to the job so if we've got a light stick on it you'll see it a mile away you can say got a visual kick coming down and it's just more professional right next one so the next tip I've got for you is use sacrificial markers to mark out your drop lobe area what do I mean by sacrificial marker it could be a nut with a bit of rope on it and a light stick or absolutely anything to give you a visual reference point of where that load needs to be now why would you need to use a marker if you can see the ground in front of you say for instance you're using your own sandy bottom okay you've put something down the ground but the supervisor tells you it needs to be picked up and shifted two meters towards you or two minutes to the right doesn't really matter so you've got the sacrificial markers these old rusty nuts with a bit of rope and a light stick on it you can then put that two meters away and you've got a visual reference point of where you need to put the load down because once you pick it up and it starts floating around then you're not going to have a visual reference point of where it meets where it's come from to judge that two meters so as long as you have a place that where you can put that down Bob's your uncle the last thing I've got for you guys is probably one of the most important it should have been a started video but here it is and it's a combination of three things pinch points body positioning and situational awareness as the famous saying in the industry don't put your fingers where you wouldn't put your I know you wouldn't want to put your member anywhere that it's going to get squished so why would you put your hands there if you always keep that in your mind and you're never going to get your hands into an area where they might get pinched especially when you're doing crane ops someone else is operating a crane they can't see what you're doing it's just common sense really your body positioning is always a key ingredient and that comes with situational awareness understanding where the crane movements are going to come from and the directions that you're giving are they relative to what the crane driver is seeing as well so I always have a little tip I use one of the markers that I was talking about in the previous tips and I drop it on the crane side of where the load needs to be so that I know when I'm giving those directions even if I'm disorientated if I've spun around or if I'm looking back I can see that marker I can always understand that all right that is the visual point that the crane drivers got that's how I need to give my direction so even if it's my left it says right and so on and so forth and the last thing about body is whenever this crane movement especially coming from over top you need to make sure that you're in a safe area whether you're back at the launch recovery area or whether you're under the Bell or whether you're inside a subsea structure you've got to have an understanding of where that loads coming from where it's going to making sure you're not underneath it and also that your umbilical is always clear too many times I've seen guys drop a load on their umbilical and low visibility conditions and they've had to go and pick the load back up fortunately not damage the umbilical but the chances are that they could have and they could have been trapped here without a lifeline so that's it right guys if you found the information that's video helpful or informative in any way please do give it a thumbs up better be much appreciated and it would help our channel grow without further ado here's the video that I was talking about of the crane failure in India how it dropped the pipe onto a material barge with crew standing on it nearby you'll see that everybody was alright there was no injuries but it was risky business see you next time [Music]
