-noglik- kirjutas:Ehk keegi on leidnud ja leidub sellest kohast väljalõikamata osaga video või mõni teine sama kohta ja suures plaanis võetud kaader?
Oleksin tänulik viite eest, mis õigele kohale juhib.
Seda, et see video on täpselt sellest kohast ära lõigatud, kus ROV liigub edasi mööda pirnvööri jäämurdetäävi ja jõuab peaaegu selle lõppu (mis lõpparuande kohaselt põhjustas kokkupõrkel eest ära kukkuva visiiriga sellele selle suurema "mõlgi"), on ka siinpool ammu tähele pandud
aga mina ei ole leidnud midagi, mis edasi aitaks. Ei pikemat (kärpimata) videot, mõnda teist videot, ega pädevaid pilte.

Sarb Marine Sprint 101
client: Rockwater
vessel: Semi One
Tape number: 02
Task: Examination of bulbous bow of Estonia
Seda on lõigatud:
14:02:12 - 14:12:08 (10 minutit puudu)
14:20:00 - teadmata aeg
Samas pole õrna aimugi, kust see video algselt üldse pärineb/kes kust millal selle on saanud ja esimesena netti riputanud... kes seda millal lõikunud on.... jne
https://www.youtube.com/watch?v=OAQY4WVPBAsUK videoanalüüsi- ja produktsioonifirma "Disengage" tegi osadele videotele omal ajal ka analüüsi. Nende hulgas olid ka videokassetid, mis filmitud 02.12.1994-04.12.1994
Kõnealune video peaks pärinema videokassetilt "B40a/number 6"

* IMHO meiesugustel "diivanispetsialistidel" pole hetkel midagi muud teha... tuleb ära oodata uute eeluuringute aruanne + 3d fotogramm-meetria tulemused ja 3D modelleerimise tulemused ja loota, et siis midagi ka avalikult jagatakse...
Lootust natukene nagu oleks...
Modern analysis methods for Estonia investigations - vital areas to investigate.
Film material show damage on bulbous bow. There are several instances of damage visible
in the film material. This suggests collision with an object that could have been quite strong
considering the very strong construction of the bulbous bow according to the GGE report.
Compare this material with reports from earlier incidents that could have caused damage to
the bulbous bow. This damage was never investigated or commented by JAIC.
It is also important for a new investigation to analyze the video tapes filmed at the bow, mid-
ships and at the stern to confirm or reject if the hull up to 1 meter below the fender bar was
visible before the rocks were dropped on this position. Then it should have been possible to
detect the big damage on starboard side if divers or ROVs covered all of the ship with their
filming.
The sonar picture above also serves to illustrate the damage to the starboard side of the visor,
Heavy impact through collision with the bulbous bow or alternative? The picture above also
shows a damage on the starboard side that is not present on the sonar picture to the left. A
big part of the steel hull has been bent outwards from the visor. This damage needs to be
analyzed and also the force needed to bend this part of the visor with FEM analysis. A new
investigation needs to clarify when this damage occurred.
3D analysis of visor and bulbous bow.
Analyze the damaged areas of visor and the shape of the bulb in a 3D simulation to confirm
or reject if it is possible to explain damage by collision between visor and the bulbous bow
on the ship. This is achieved with the use of a portable 3D scanner and that information is
imported into a 3D model covering both the damaged visor and a 3D model of the bulb in
the bow.
Analysis of surfaces of visor.
The surfaces of the visor need to be investigated in order to find possible traces of collision
with foreign object. Material like titanium, aluminum alloys or steel may be present on the
surfaces. Several areas of the starboard side and port side of the visor needs to be examined.
On the starboard side of the visor there is a very sharp straight edge between an area without
paint and an area below with the white paint still intact. This sharp edge needs to be ana-
lyzed. The other edges of the area without paint also need to be analyzed. The shape of the
paint at the edges could indicate if the surface has been burnt when the damage occurred or
if the paint has been removed by mechanic deformation during collision with foreign object
or collision with the bulbous bow.
Photogrammetric investigation of the bulbous bow, shell- and bottom plating
This information will be used to analyze any damage to bow of the ship. This will be trans-
formed into a FEM analysis to rule out if any foreign object has hit this part of the ship. This
will also answer the question of what force and energy content would be needed to cause
any damage.
Photogrammetric investigation of the shell- and bottom plating will answer the question if
some water tanks were open to the sea which could have added to the sinking sequence.
