That thing is huge jds! wonder what it weighs. size "i would guess around 4 feet" Good guess, I looked at the pallet it is sitting on, standard pallets are 40" X 48" and it sits to the edge.
BSL dogs #msg-24209563 B..S Latcher by Deep Down Inc., Umbilical stiffener latching mechanisms have always caused installation problems as well as expensive diver operations for expansion developments. DDI management conceived the very first ROV installable latching mechanism we have heard of. Divers installed a Bell mouth with locking dogs on the bottom of the I-tube. During the umbilical installation, the bend stiffener could be latched in with a ROV and the umbilical could be pulled up the remaining distance and hung off. During the BP Aspen installation, a competitive version of Bell mouth failed allowing DDI to develop a new type of latcher which was spring loaded. This allowed the latcher to fit onto an existing flange, completely eliminating the need for divers both prior to and during the installation. The BS Latcher can be designed to fit onto any existing flange on the bottom of an existing I-tube. ..find out more about this product at Deep Down Inc.
Just a small addition to the great DD flowing onto the board today.
On the BS latcher
the silver bricks (lead) are slightly bigger than a house brick--
the silver bricks are zinc anodes (they do look like lead) and they act to prevent corrosion by being the sacrificial anode
They're not painted so that they can be in direct contact with the seawater. By their size, I'd imagine the service interval to be several years before needing replacement.
Seems like a trivial tidbit to add compared to the big picture being painted here, but there you go, sacrificial zinc anodes!
