Don’t know if that is the case here, but many ships of this size/type is set up to use ballast water for cooling when sitting dry in ports with large tidal difference.
Cooling water is circled from/to one or more ballast tanks while the tide is out.
Ah, so they dropped the anchors after she was aground and drifting astern?
Or, here’s a thought, mechanical failure, dropped both hooks, overran them and then drifted astern on the ebb.
I can’t be arsed to see what the tide was doing at the time.
I will not cross swords but i am betting : 1. my version 80%
2. your version 20%.
But i will bet 100% there is not even 1 shackle (27.5 m) on the winch yet. ( 1 white-kenter-1 white)
Letting go 2 anchors with such precision in surely a stresfull situation is a feat worthy of magician -exactly same length ???
Man!!! I like bedtime stories but not this one.
Any way I do admire your belief in " human goodness "
The picture as far as i am concerned is " too good, too perfect " to be true. But may be You are right 20%
Famous scribler for Splash247 Andrew Craig Bennett replied once to me : do not be naive WE ALL LIE IN SHIPPING
Letting go one or both anchors at depth of 1 foot UKC or about may cost You ripped bottom and a dry dock bill.
Wonder why they do not calculate the pressure on the ground at the highest water , apply some reasonable factor for friction /suction or watever and try to figure the force ( abt) required to pull her off at HW. It is not a rocket science.
Disconecting anchors and using both chains for pulling is not impossible task either. But then this would be like salvage and cost a lot . So they may stay 3 weeks waiting for HHW or for some ORKAN that will push enough water into the river. We will see.
