To block the giant, to trigger the tragedy could have been a valve.
Worked before, the mighty engine of the "Jolly Nero", the leaves from the pier Nino Ronco. It is broken down later, disaster occurred when the cargo pilots had shot down the tower and killed whoever was working. What happened in between, those damn 45 seconds in which the master Roberto Paoloni realized that they no longer control and announced the failure is still unclear. But investigators start from an element: that type of engine can not start moving when the pressure of the compressed airthat starts it is insufficient.
There is need for clarity, of fixed points. And we need to hurry. Why underwater and rubble were eight people dead and one missing, and why the detention in port there is a mastodon that sooner or later will have to start over. The skill flash with the Prosecutor moves from a possibility emerged in the early interrogations crew: the 'impasse and failure to respond to commands could be derived from the failure of a pneumatic valve, which in turn could have affected the necessary pressure for goodwill.
In this overview of the experts are evaluating the importance of defaillance that has complicated the communication between the navigating bridge and the engine room, defined by Messina "with no relevance."Is it really so? On this point, investigators do not become imbalanced. In those dramatic moments, a few seconds may have made the difference.
Engines mounted in '75, but "all certificate '
The analysis of the causes of the massacre from a matter of fact, he has found evidence already in the minutes after the impact: the failure was 'temporary'. The "Jolly Black", launched in 1976, works with a "Burmeister & Wain," Danish very reliable engine, two-stroke and reversible. He had been duly certified by RINA and, if maintenance is correct, can easily last for forty years. To change direction goes off, it must be reversed course and then you can reboot: an operation that lasts a few seconds, under normal conditions.
The night did not go so damn. Proceeds "reverse" the ship to the docks. The captain turns off the machines, has the inversion, but just do not restart the machines: they are blocked, and the colossus of the Sea shall in momentum. Why? The burst phase of the motor is anticipated goodwill air. The air, in short, is powered by compressors and contained in a reservoir. If the level of pressure, for some reason, are not correct trouble. That's what happened? Where was the problem? Hypothesis, of course, is that the "pneumatic valve goodwill 'did not work as it should, resulting in too low a pressure on the piston. Another crucial question, which currently has no answer: how long did the "blackout"? Early indications could come as analyzing the instruments on board, which records all the crucial steps.
The "yellow" on the failure of the communication
A failure has been verified, the "Jolly Black" was. Went haywire the "telegraph", a tool that is used to transmit orders to the bridge, which was attended by the commander and the pilot Antonio Paoloni Anfossi (both under investigation for multiple manslaughter and assisted byRaymond Romano, Carlo Golda and Francis Munari) and the engine room, which houses the personnel required to execute orders.
Here is a sort of twin machine: when you take a course with the Directive, a pulse should report to the board that the maneuver was carried out. The indicator that you should have, in fact, was broken. A drawback which the crew had obviated through the use of phones andwalkie-talkies.
For owners that mishap "did not affect" the incident. But prosecutors do not neglect any detail.The investigations, conducted by the chief prosecutor Michele Di Lecce and the substitute Walter Cotugno, proceed in record time. Yesterday morning at nine was entrusted with the expertise and capabilities of the ship's engines. In the early afternoon the experts were already on board.
The technical consultants appointed by the prosecution are Admiral Mario Caruso and Rear Admiral Claudio Boccalatte, both officers of the navy of La Spezia. The defenders of the suspects have hired two technical officer, the captain and the engineer Enrico Casella Camillo Mattarelli.
