9 mins confidence:   peer agreement (net): -1 9-strand cable
Explanation:
a 'moufle' is a pulley ('block' in nautical speak)
Routledge gives 'mouflage' as a term used by the oil industry for 'block' however I've never heard a block being designated according to the number of strands in the rope it takes rather its diameter.
Perhaps they are talking about a block with nine sheaves (wheels) but that seems excessive
a 'brin' is a component of rope or cable and is definitely translated as 'strand'

mind you, with 100 metres of cable it may well be a nine-sheave tackle

in that case they may be using 'brin' as a synonym for the number of parts in the tackle, like a "nine-part tackle"

Note about the term 'parts':
The mechanical advantage of a block and tackle is equal to the number of parts in the line, that either attach to or run through the moving block, or the number of supporting ropes. For example, take a block and tackle with 2 sheaves on both the moving block and the fixed block. If one compares the blocks, one will see one block will have 4 lines running through its sheaves. The other will have 4 lines running through its sheaves (including the part of the line being pulled or hauled), with a 5th line attached to a secure point on the block. If the hauling part is coming out of the fixed block, the block and tackle will have a mechanical advantage of 4. If the tackle is reversed, so that the hauling part is coming from the moving block, the mechanical advantage is now 5.

Depending on how you make off the standing part, you could have a nine part tackle with 2 x 4 sheaves or 1 x 4 sheaves and 1 x 5 sheaves on the moving end.

I don't see any problem with purchase except that you use 'fold' as:
Three-fold purchase. This consists of two treble blocks; its V.R. is 7 if rove to advantage (see fig. 3), and 6 if rove to disadvantage (see fig. ...

I think I better draw a line under my peregrinations... I'd go with either 'ninefold purchase' or 'nine-part tackle'.

12 mins confidence: peer agreement (net): +1 | mouflage à neuf brins 9:1 purchase
Explanation:
I have to say that I am guessing, as I have never personally come across this term. However, GDT suggests 'mouflage' as 'rigging of blocks', which is descriptively accurate even though it isn't the exact term that suits here, I don't think.
It means that the cable passes round the blocks 9 times, thus acheiving a 9x mechanical advantage but entailing a 9-fold increase in the length of cable (i.e. the velocity advantage is 1/9th)
Hence moving the passerelle 11 m entails the movement of 9 x 11 m of cable, = 100 m.
I think there are various ways this can be expressed in EN, but from my distant nautical days, I think blocks-&-tackles are usually expressed in terms of a 'purchase' ratio.

From my experiences of things like cross-Channel ferries, yes, Graham, they do indeed use these massive 9-sheave blocks — it's quite impressive to see what a massive tackle that makes, with so much cable — but then, it has to carry a lot of weight!

This Wiki article explains and illustrates it all pretty well:

'reeving system' refers to the way the rope/cable is threaded round the sheaves making up the blocks; it IS the right word, but sounds odd when used like this in EN; I believe this is the more normal way it would be expressed in natural EN.
