Calc Darling in the Franxx - Last ride of Strelizia

Stelitzia rams Hringhorni through the VIRM fleets and into the VIRM home planet at incredible speeds. Thankfully, we already have the dimensions for Strelizia Apus sorted, but now we need Hringhorni's dimensions. This should be much easier than Strelizia Apus's dimensions. Strelizia Apus' arm protectors are 85840.8839m long, and those on Strelizia True Apus should be a similar length.
505 pixels = 85840.8839m
1 pixel = 85840.8839m/505 = 169.981948m
169.981948m X 2166 = 368180.899m
169.981948m X 123 = 20907.7796m
36 pixels = 20907.7796m
1 pixel = 20907.7796m/36 = 580.771656m
580.771656m X 1096 = 636525.735m
580.771656m X 276 = 160292.977m

It's not a perfect triangle, but given there's also other pyramidal parts sticking out, I figures it'd even out.
503 pixels = 160292.977m
1 pixel = 160292.977m/503 = 318.673911m
318.673911m X 92 = 29317.9998m

With all that done, let's get our volume by adding all three triangular parts together as triangular pyramids. To get that though, we need the area of the triangle first.

A = hbb/2
= 636525.735 X 160292.977/2
= 5.10153025e10m^2

V = 1/3AH
= 1/3 X 5.10153025e10 X 29317.9998
= 4.98555543e14 X 3
= 1.49566663e15m^3

Now for the shaft.
812 pixels = 636525.735
1 pixel = 636525.735/812 = 783.898688m
783.898688m X 319 = 250063.681m
783.898688m X 32 = 25084.758m
25084.758m/2 = 12542.379m

Volume as a cylinder.

V = πr^2h
= π X 12542.379^2 X 250063.681
= 1.23583455e14m^3

There are other bits too, but...eh. Let's get our total volume.

V = 1.49566663e15 + 1.23583455e14
= 1.61925008e15m^3

Hringhorni is made out of Klaxosaur cores, which are composed of some form of weird goo, so we'll go with the mass of water, that being 1000kg/m^3.

M = 1.61925008e15 X 1000
= 1.61925008e18kg

As previously caclulated, Strelizia Apus weighs 7.2176079e18kg, and Strelizia True Apus should weigh the same.

M = 7.2176079e18 + 1.61925008e18
= 8.83685798e18kg

Now all that's left is the easy, fun part!
43 pixels = 368180.899m
1 pixel = 368180.899m/43 = 8562.34649m
8562.34649m X 1349 = 11550605.4m
Timeframe is 3 seconds.

852 pixels = 11550605.4m
1 pixel = 11550605.4m/852 = 13557.0486m
13557.0486m X 695 = 9422148.78m

T = 9422148.78m/3s
= 3140716.26/340.29
= Mach 9229.52852

At these velocities, we can just start to apply relativistic kinetic energy, so we enter the above values into the relativistic kinetic energy calculator and get a result of 4.359E+31 joules, or 10.418260038240916288 zettatons.

Final Results
Strelizia True Apus rams the VIRM planet (speed) = Mach 9229.529
Strelizia True Apus rams the VIRM planet (energy) = 10.418 zettatons
