Contract analysis

I. PURPOSE AND OVERVIEW The purpose of this memorandum is to prepare Chief Engineer Petros Vlahos for his deposition, which is currently scheduled for June 28, 2024. The deposition has been noticed by Hargrove, Delacroix & Stern LLP ("HD&S"), counsel for Plaintiff Northwind Maritime Corporation ("Northwind" or "Charterer"). The lead partner at HD&S responsible for this matter is Margaret Delacroix. Based on the staff

II. WITNESS BACKGROUND AND BIOGRAPHY A. Professional Background Petros Vlahos is the Chief Engineer of the M/V Aegean Fortuna. His full legal name, as reflected in his seaman's documents and employment records, is Petros Ioannis Vlahos. He is a Greek national. Vlahos is employed by Thalassa Shipping & Logistics SA ("TSL"), which serves as the operational employer and technical manager of the vessel. The M/V Aegean Fo

III. ANTICIPATED AREAS OF QUESTIONING This section sets forth the areas in which Vlahos is most likely to face questioning from Northwind's counsel, organized by topic. For each area, we identify the relevant factual narrative, TSL's defensive position, the anticipated lines of attack by Northwind, and key points that Vlahos should emphasize in his testimony. A. General Vessel Maintenance During Charter Period Northw

1. Factual Narrative On or about March 12, 2022, the main engine turbocharger aboard the M/V Aegean Fortuna suffered a failure while the vessel was transiting the Indian Ocean en route from Paradip, India to Mombasa, Kenya. The precise nature of the turbocharger failure — which is expected to involve a bearing failure, blade damage, or a combination of both — should be confirmed with Vlahos at the preparation session

2. TSL Defense — Latent Defect TSL's position on Incident 1 is that the turbocharger failure was attributable to a latent defect — that is, a defect in the turbocharger that was not apparent upon reasonable inspection and was not attributable to negligent or inadequate maintenance by TSL or its crew. Under the charter-party (and under general maritime law principles), an owner is not liable for off-hire resulting fro

3. Anticipated Northwind Lines of Attack Northwind's counsel, guided by the opinions of their expert Capt. Julian Blackmore (Blackmore Maritime Advisory Ltd., London), will likely pursue several lines of attack on Incident 1: (a) Insufficient Maintenance Intervals: Northwind may argue that the intervals between turbocharger inspections or overhauls were longer than the manufacturer's recommendations or industry best

4. Key Points for Testimony Vlahos's testimony on Incident 1 should emphasize the following points: • The turbocharger was maintained in accordance with the planned maintenance system and the manufacturer's recommended service schedule; • GMCB surveys during the relevant period did not identify any deficiency in the turbocharger; • There were no warning signs — or, if there were ambiguous indicators, they were within

1. Factual Narrative On or about July 8, 2022, the M/V Aegean Fortuna experienced a dual mechanical failure while loading cargo at the port of Richards Bay, South Africa. The first failure involved a malfunction of the vessel's ballast water treatment system (BWTS), which rendered the system unable to treat ballast water to the standards required by the International Convention for the Control and Management of Ships

2. TSL Defense — Charterer Causation / Contaminated Ballast TSL's defense on Incident 2 is that the BWTS malfunction was caused by the intake of contaminated ballast water at a prior port call, and that the contamination was attributable to Northwind or Northwind's agents, who directed the vessel's trading pattern and were responsible for port selection and cargo operations. To support this defense, Vlahos should be

3. Connection to Cargo Damage Claim Northwind has asserted a cargo damage claim in the amount of $3,420,000, alleging that the iron ore cargo loaded at Richards Bay sustained oxidation damage during the off-hire period associated with Incident 2. This claim is separate from the off-hire claim and raises its own set of factual and legal issues. Vlahos's testimony on the cargo damage claim should address the following

4. Anticipated Northwind Lines of Attack Northwind's counsel will pursue several lines of attack on Incident 2: (a) Challenging the Contaminated Ballast Theory: Northwind will argue that the BWTS malfunction was caused by inadequate maintenance of the system rather than by contaminated ballast. They will ask whether Vlahos tested the ballast water at the time of intake at the prior port, whether he reported any conta

5. Key Points for Testimony Vlahos's testimony on Incident 2 should emphasize: • The BWTS was functioning normally before the intake of contaminated ballast water at the prior port; • The contamination was the proximate cause of the BWTS malfunction; • The contaminated ballast was loaded at a port selected by Northwind or Northwind's agents as part of the vessel's trading pattern under the charter-party; • Any contem

1. Factual Narrative On or about November 15, 2022, the M/V Aegean Fortuna experienced a failure of a main engine cylinder liner, the nature of which — whether cracking, wear beyond permissible limits, or catastrophic failure — should be confirmed with Vlahos at the preparation session. The failure was sufficiently serious to require drydocking for repair. The vessel was diverted to Keppel Verolme Shipyard in Rotterd

2. TSL Position — Concession on Maintenance Failure, Dispute on Quantum Unlike Incidents 1 and 2, TSL has conceded that the cylinder liner failure in Incident 3 was attributable to a maintenance deficiency. This concession was made after careful review of the facts and consultation with Dr. Sørensen and other technical advisors. Vlahos must fully understand this concession and its implications for his testimony. He s

3. Anticipated Northwind Lines of Attack Northwind's counsel will pursue several lines of questioning on Incident 3, with a particular focus on using the conceded maintenance failure to undermine TSL's defenses on Incidents 1 and 2: (a) "If you concede this was a maintenance failure, why not the others?": This is the most predictable and potentially most damaging line of questioning. Northwind will attempt to use Inc

4. Key Points for Testimony Vlahos's testimony on Incident 3 should be guided by the following principles: • Be honest and forthright. TSL has conceded the maintenance failure, and Vlahos should not try to minimize it, explain it away, or characterize it as anything other than what it was. Evasiveness or defensiveness on this point will damage Vlahos's credibility on the points that matter most — his testimony about

IV. KEY DOCUMENTS FOR REVIEW A. Documents Vlahos Must Review Before Deposition The following documents must be assembled and provided to Vlahos in advance of the preparation session. Vlahos should review all of these documents carefully, as any of them may be presented as exhibits during the deposition, and he must be prepared to identify, explain, and provide context for each.

1. Charter-Party (NYPE 2015 form, as amended), dated December 3, 2020 (Charter-Party Reference No. NW-TSL-CP-2020-1203) — Vlahos should focus particularly on the following clauses: • Clause 2 (Owner obligations); • Clause 5 (trade limits); • Clause 6 (maintenance and seaworthiness — the obligation to maintain the vessel in a "thoroughly efficient state of hull, machinery, and equipment" and compliance with GMCB class

2. Engine room logbooks for the M/V Aegean Fortuna covering the period from January 2021 through December 2022, with particular focus on the three incident periods (March 2022, July 2022, and November–December 2022).

3. Planned maintenance system (PMS) records for the following equipment: • Main engine turbocharger(s); • Ballast water treatment system (BWTS); • Auxiliary boiler; • Main engine cylinder liners (all cylinders).

4. GMCB survey reports and class certificates for the period from 2020 through 2023, including annual survey reports, intermediate survey reports, any special or renewal survey reports, and any condition of class notifications.

5. Repair records from the three incident repairs: • Colombo, Sri Lanka (Incident 1 — turbocharger, March–April 2022); • Richards Bay, South Africa (Incident 2 — BWTS and auxiliary boiler, July 2022); • Keppel Verolme Shipyard, Rotterdam (Incident 3 — cylinder liner, November–December 2022).

6. Ballast water exchange and treatment records for the period from June through July 2022, with particular attention to records of ballast water intake at the prior port alleged to be the source of the contamination.

7. Correspondence with GMCB surveyors — all written communications between Vlahos (or other engineering officers aboard the vessel) and GMCB surveyors during the charter period.

8. Correspondence with TSL shore-side technical management regarding the three incidents — including emails, memoranda, and any other written communications between Vlahos and TSL's technical department in Athens/Piraeus.

9. Spare parts requisition records — all spare parts requisitions submitted by Vlahos during the charter period, particularly those relating to the turbocharger, BWTS, auxiliary boiler, and main engine cylinder liners.

12. Depositions of Alexandros Stavridis (April 22, 2024) and Capt. Nikolaos Giannopoulos (May 10, 2024) — relevant portions for consistency review. Vlahos should review the transcripts of these depositions, focusing on passages that address the three incidents, the vessel's maintenance regime, and the Maputo deviation.

13. TSL's Responses and Objections to Northwind's First Set of Interrogatories (served February 28, 2024) — relevant answers regarding the three incidents, the maintenance regime, and the Maputo deviation.

14. Personal notes, emails, and Meridian Services Inc. messages — any personal notes, emails (whether on TSL email systems or personal email accounts), or Meridian Services Inc. messages that Vlahos has relating to the three incidents, the vessel's maintenance, or any communications with Northwind's agents, GMCB surveyors, or TSL management. B. Documents Likely to Be Used as Exhibits by Northwind's Counsel In additio

V. CONSISTENCY WITH PRIOR WITNESS TESTIMONY Consistency among TSL's fact witnesses is essential. Inconsistencies — even on minor points — will be exploited by Northwind's counsel to undermine credibility and to create the impression that TSL's witnesses have been coached to present a coordinated but unreliable narrative. At the same time, Vlahos's testimony should not be so perfectly aligned with prior testimony as t
