that vryhof anchor only should be used for "pleasure" sailboats to deliver cargo without engine while oil rigs should be dismantled along offshore turbines i made a hybrid replica of vyrhof's stevshark rex with also similar ballastless mantus anchor shape
Nice video, Stian! I was wondering. If the anchors are pre-layed, does an oil-rig still need help from an AHTS when it arrives on location? I know it needs help when leaving.
The AHTS would typically pull the rig out on site. Then we would have 4 vessels, one on each corner. The AHTS's would come in, two at a time, diagonally, and we would give each its pennant, which they would then connect to its respective anchorchain, via a kenterlink wich is kind of like a shackle. Then the rig will pull in on the chain till it's tight. The vessels come in on each corner and collec their second pennant, and repeating the previous. The rest is up to the rig, pulling on each chain as much as needed, depending on sea depth. A rig will typically have 8 anchors, 2 on each corner. A minimum of 3 or two AHTS is needed, but we always used 4. Is there any chance i got this right, Stian? Used to work on Borgland Dolphin.
Finally a vessel who knows how to use that anchor frame! Someone needs to show maersk how to do it!
Great video man
Your wish came true 4 years later now that DOF(company that owns this vessel) has bought out maersk's anchor handling division.
Good and easy work
Thank you
Great video man. Thank you for sharing 👊
LordJimSMA thank you :)
Three of these vessels are in Australia right now.
Great video Stian. How big is the Stevpris anchor, how many tons is the weight?
Thank you. The weight of the anchor is 18 tons

Thank you. Yes, they need our help when they arrive:)

Are you on DP when doing anchors?
Stian,
I am interested in working offshore, specifically on a AHTS. Do you think we could direct message about how to enter the industry?
Nice video⚓️
How long time is needed for pre-laying each anchor?
About 4 hours:)
Thank you @@norway.maritime !!
No problem:)
what are giant anchors like this used for?
oil rigs, wind farms, maybe floating fish farms?
