Recorded interview transcript
LEAD INSPECTOR: State your full name for the record.
DR MARA VINTER: Dr Mara Vinter
LEAD INSPECTOR: Do you understand the status of this interview and the limits placed on distribution?
DR MARA VINTER: Yes. I also understand that a classification marking is a handling instruction, not proof of integrity.
LEAD INSPECTOR: Have you been offered the representation, legal advice or staff support applicable to this procedure?
DR MARA VINTER: Yes.
DOCUMENTARY EXHIBIT D-01 Retained extract: NORWEGIAN SUBSEA ARCHIVE – DAY 91, 06:00 GMT At 06:00 GMT, Mara Vinter was shown a power trace from a place she had helped bury. Associated persons: Commander Lydia Green Relevant systems or locations: RV Meridian, North Sea, identity, archive
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: At the time I acted on what the bridge could physically verify, not on what a later system said I ought to have known. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: What did you understand at that moment, before later analysis supplied a larger explanation?
DR MARA VINTER: I accept the event. I do not accept the conclusion you have attached to it. I will not improve my memory to make the chronology easier.
DOCUMENTARY EXHIBIT D-02 Retained extract: Harriet pulled once, efficiently, and released her the moment both boots touched Meridian’s deck. “Dr Vinter.” “Captain Caldwell.” Associated persons: Harriet Caldwell
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: That is the order as I remember it. The machinery and the later summary are separate questions. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: Who else was physically present and capable of confirming your account without relying on the same electronic record?
DR MARA VINTER: That is the order as I remember it. The machinery and the later summary are separate questions. My answer is limited to what I personally saw, heard or ordered.
LEAD INSPECTOR: Are you saying the official record is wrong?
DR MARA VINTER: I am saying the record should remain evidence, not become an alibi for the system that produced it.
DOCUMENTARY EXHIBIT D-03 Retained extract: Mara Vinter had warned that the flooded service lock would become much harder to approach once the tide built across the collapsed foundation. “Photograph before removal,” Fiona said. Relevant systems or locations: North Sea
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: That is the order as I remember it. The machinery and the later summary are separate questions. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: Why was the matter not escalated through the ordinary reporting route?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. My answer is limited to what I personally saw, heard or ordered.
DOCUMENTARY EXHIBIT D-04 Retained extract: No command payload beyond the six-point-four-second event window unless it opens as part of the same public incident record.” Mara Vinter repeated the limits from the second paper copy. Associated persons: Raul Manuel Diaz Relevant systems or locations: identity
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: At the time I acted on what the bridge could physically verify, not on what a later system said I ought to have known. If the original is no longer available, that absence should remain part of your finding.
LEAD INSPECTOR: What part of the retained record is incomplete or misleading?
DR MARA VINTER: I accept the event. I do not accept the conclusion you have attached to it. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: Are you saying the official record is wrong?
DR MARA VINTER: I am saying the record should remain evidence, not become an alibi for the system that produced it.
DOCUMENTARY EXHIBIT D-05 Retained extract: Mara Vinter stood behind a paper copy of the maintenance map. Relevant systems or locations: radar
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: That is the order as I remember it. The machinery and the later summary are separate questions. Check radar against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Which physical record should be examined before this account is treated as settled?
DR MARA VINTER: I accept the event. I do not accept the conclusion you have attached to it. My answer is limited to what I personally saw, heard or ordered.
DOCUMENTARY EXHIBIT D-06 Retained extract: Mara Vinter beside the acoustic station.” Natalie answered through the separate return telephone, forcing the conversation to travel a different route from the evidence update. Relevant systems or locations: evidence
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. the person who held the contemporaneous log can confirm the sequence, but not necessarily the interpretation.
LEAD INSPECTOR: Did anyone instruct you to describe the incident differently afterwards?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. If the original is no longer available, that absence should remain part of your finding.
LEAD INSPECTOR: Are you saying the official record is wrong?
DR MARA VINTER: I am saying it may be accurate about the event and wrong about the cause.
DOCUMENTARY EXHIBIT D-07 Retained extract: Mara Vinter put both hands on it and tried again.
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. Check the physical record against the unprocessed record before you accept the later label.
LEAD INSPECTOR: What did you understand at that moment, before later analysis supplied a larger explanation?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. I will not improve my memory to make the chronology easier.

LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DR MARA VINTER: You are asking for certainty that did not exist on the deck. I can give you the decision and the reason for it. Check archive against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Who else was physically present and capable of confirming your account without relying on the same electronic record?
DR MARA VINTER: That is the order as I remember it. The machinery and the later summary are separate questions. I will not improve my memory to make the chronology easier.
LEAD INSPECTOR: Are you saying the official record is wrong?
DR MARA VINTER: I am saying you should preserve the contradiction instead of choosing the tidier version.
[Exhibit S-01 introduced. Subject permitted to inspect the displayed copy without handling the source medium.]
LEAD INSPECTOR: Do you identify the person shown as yourself?
DR MARA VINTER: I identify myself in the frame. I cannot authenticate the date from the crop alone.
LEAD INSPECTOR: Can you establish the location or date from anything visible in the frame?
DR MARA VINTER: The location is supportable from the surroundings. The purpose you are implying is not.
LEAD INSPECTOR: Were you aware that the image was being made?
DR MARA VINTER: I was not aware of the camera at the time shown.
LEAD INSPECTOR: Who had advance knowledge of your presence at that location?
DR MARA VINTER: That depends on whether the source is an official system, a copied feed or a separate observer.
LEAD INSPECTOR: What does this image prove, and what does it not prove?
DR MARA VINTER: Preserve the frames before and after it. A single image is a fact about light, not a complete account of conduct.

LEAD INSPECTOR: Is there any material fact you have withheld because you consider this recording or its distribution unsafe?
DR MARA VINTER: No fact material to immediate safety. Other matters require a narrower compartment.
LEAD INSPECTOR: What is the single next action this investigation should take?
DR MARA VINTER: Compare the surveillance timeline with access, maintenance and movement records before drawing a conclusion.
LEAD INSPECTOR: Do you wish to add or correct anything before the recording is suspended?
DR MARA VINTER: Preserve the questions I declined. They may matter more than the answers you expected.
[Recording suspended. Source media sealed. Any resumed session requires a new opening declaration and exhibit schedule.]
