Can only say marine oporates differently from platforms, B W don’t conform to LOLER it all comes under Marine ship regs
They don’t carry spare winch ropes, ropes are changed when certification dictates
There are a few scenarios regarding the rope,it’s possible that the pull in rope was dynima initially then at some point this co7ld have been choked off and a SWR attached this would have taken place inside the moon pool, now the SWR completes the pull in and the dynima rope becomes a preventer, was the winch over laid and dropped down straight pull or was the line lead to a head block. Or diverter block ? if it’s the latter then these attachments will need to be re tested, examined mpi/ndt or bolt change out depends on the type of fixing, lots of unknowns to get full picture, but as I said before the F%#£ factor is always about, and as said before it will be sorted
Yuyus, a SWR has to be spooled under tension that requires a spooling tensioner a dynima rope dose not as crushing is not a problem
Miidus, lets be honest, we don’t even know if the rope is SWR (steel wire rope) or dyminia man made fibre rope, I would have thought it would have been SWR, if it was SWR then the fail is more complex if it was dyminia it’s a more easy fix, IMO the fail was caused buy dynamics, as has been already pointed out at the stage of parting the bouy was almost home and at that stage the rope would have been at its shortest, distance between conection point and winch if the vessel takes a rise at this crucial point then over load occurs going into unknown dynamics, let’s hope it was a rope ,rope as can be easy fix, steel rope much more to concider
Yes the bouancy would have prevented impact with sea bed
Could be coming in to take up heading line
So pleased to hear that some good came out of the YTS scheme, more power to you all
Back in the eighties in worked on the Thistle platform, commonely knowen as the black pig this name came about due to the drilling mob Santa -Fa squirting there shite all over the place mud, fluids, brine, oil,the Thistle had two drilling rigs
At that time one was removed latter, the YOP scheme was on the go and Santa -Fa took on six yoppies 18,20 year old kids as ruff necks to learn the game within 1 week 4 of them were hospitlised 2 flew out the V door and two went for a spin around some drill pipe, that was the end of the yop recruits not funny then but makes me laugh now, anyway as I said working on thistle we had a project called the don field,due to nobody wanting to work on the thistle black pig all new service hands new recruits were told your going to the Don field so gladly getting on the chopper and arriving on the black pig,they used to think that they were only stopping to fuel up, naw am going to the Don field they would say
And I would say your hear get aff the chopper welcome to the black pig, now after months and months of drilling in the don field and all sub sea work complete, and the Don riser tied back to the black pig it was all systems go, chokes were opend,guess what not a drop of oil ever reach the black pig from the Don field, now 30odd years latter Enquest have the Nothern producer sitting on the Don field and producing 3/4 thousands bopd just saying it’s a funny old business the oil game
It’s the bouy that is anchored not the vessel
You mean after a successful bouy connection, yes time scale is all about F%#£ factor, Oh F%#+ that’s the wrong size, Oh F%#£ that will not fit,F%#£ me who put that there on average the F%#£ factor will increase cost and delays on any hook up opps,but in the end always get there,biggest F%#£ factor too your investment is continuaty of flow rates it’s been proven world wide so why not in wos, I am a believer of the doc so placed my bet
Peeps, bouy connection and hook up are two different things,hook up involves lots of systems to be commitioned tested and proved , signed off , saying that , bouy connection is first step,take a deep breath as any shit can happen during hook up it’s called the f%#+ factor
She would have hooked up full of ballast,then discharged on connection,normal rules not saying that has happened.
Has the draft changed higher or lower?
If the first attempt to hook up without heading assistance , IMO especially with WOS conditions this would have been risky, The snagged wire would have been the bouy pick up line or the pull in line ither internally or externally
No chance of the rope snagging during heading ops
Heading control is achieved by connecting a tug via a steel rope cable to the vessel you are controlling the purpose is to keep the vessel in the correct position (heading) this prevents the vessel from turning, wind, tide, etc etc
