What would Francis think? Purposefully or accidentially, it is quite symbolic to me. Add in all the other infrastructure and cities and buildings attacked by 'accidents' and the trajectory becomes pretty clear, a deep government bent on self implosion. It's all so shallow, really.

Sabotage? Perhaps, …

Container ships, primarily, have a simplest propulsion systems installed (… those are disposable ships, … at ~ 8 years old, Dali is more than 2/3 through its useful life). See diagram on page 42 *) It’s a system of fixed pitch propeller, solid connecting shaft, permanent coupling, and reversible rotation engine.

Such system is simple, cheep, … but with significant limitations. Let’s look at but just two:

1. When reversing is called for, it takes about 10 min or so of powerless drifting to change engine to run in opposite direction.

2. Fixed pitch propeller, … which results in propeller walk **)

And so imagine when your main propulsion suddenly ’pukes’, … suddenly and in confining waters (!) - at speed of about 8 kN, … with a giant bridge in a clear sight ahead, as you speeding in that 300 metre long and 50 metre wide barge with a tremendous mass and all of that, … plus all bunch of shipping containers stack up to the sky to simulate sails action!

You panic, … because you just remembered why gawd created harbour tugs!

… fwiw,

F.S.
