Addressing technical issues that occurred during the warranty period after vessel delivery, determining response policies from a technical perspective.
海外船主から引き渡し後の保証期間中に発生した技術的問題について相談を受け、技術的観点から対応方針を決定する場面です。
👨💼【Teacher / Ship Owner】:
Thank you for taking my call today. We've noticed a performance issue with the main engine during sea trials. The fuel consumption is 8 percent higher than the guaranteed value in the contract. Could you explain what might be causing this problem?
（本日はお電話ありがとうございます。海上試運転中に主機関の性能問題に気づきました。燃料消費量が契約の保証値より8パーセント高くなっています。この問題の原因について説明していただけますか？）
🧑🎓【Student / Design Engineer】:
I apologize for the inconvenience. Let me explain the possible root cause. We need to check the propeller pitch setting and the hull coating condition first. Both factors can increase fuel consumption if they are not within the design range. I will arrange an inspection team to visit your vessel within 3 working days.
（ご不便をおかけして申し訳ございません。考えられる根本原因について説明させてください。まずプロペラピッチ設定と船体塗装の状態を確認する必要があります。どちらも設計範囲内でない場合、燃料消費量が増加する可能性があります。3営業日以内に貴船を訪問する検査チームを手配いたします。）
👨💼【Teacher / Ship Owner】:
I appreciate your quick response. However, we also found cracks in 2 cooling pipes in the engine room. Are these defects covered under the warranty period? We need to know if you will handle the repair cost.
（迅速なご対応に感謝します。しかし、機関室の冷却配管2本にひび割れも発見しました。これらの欠陥は保証期間内でカバーされますか？修理費用を負担していただけるか知る必要があります。）
🧑🎓【Student / Design Engineer】:
Yes, those cracks are covered under our 12-month warranty. We will provide replacement pipes and send our repair team at no charge. The warranty includes all material defects and workmanship issues. We will also review the pipe material specification to avoid the same problem in the future. The repair work can be completed within 5 days after our team arrives.
（はい、それらのひび割れは当社の12か月保証でカバーされます。交換用配管を提供し、修理チームを無償で派遣いたします。保証にはすべての材料欠陥と施工上の問題が含まれます。今後同じ問題を避けるため、配管材料仕様も見直します。修理作業はチーム到着後5日以内に完了できます。）
👨💼【Teacher / Ship Owner】:
That sounds reasonable. But what about the fuel consumption issue? If the root cause is a design error, we require compensation for the extra fuel cost. We've already spent 15 thousand USD more than expected during the trial period.
（それは妥当に思えます。しかし燃料消費の問題についてはどうでしょうか？根本原因が設計ミスであれば、追加燃料費用の補償を求めます。試運転期間中にすでに予想より15,000米ドル多く支出しています。）
🧑🎓【Student / Design Engineer】:
I understand your concern. Let me clarify our approach. First, we will measure the actual propeller pitch and compare it with the design value. If the pitch is incorrect due to our manufacturing error, we will adjust it and cover your additional fuel cost. However, if the issue results from operating conditions outside the contract range, we need to discuss a separate solution. We will share the inspection report with you within 1 week.
（ご懸念は理解しております。当社のアプローチを明確にさせてください。まず、実際のプロペラピッチを測定し、設計値と比較します。ピッチが当社の製造ミスにより不正確な場合は、調整を行い追加燃料費用を負担いたします。ただし、問題が契約範囲外の運航条件に起因する場合は、別の解決策を協議する必要があります。1週間以内に検査報告書を共有いたします。）
👨💼【Teacher / Ship Owner】:
Understood. Please make sure your inspection team brings all necessary measuring tools. We also need a written plan for the repair schedule and the compensation process. Can you send that to me by the end of this week?
（承知しました。検査チームが必要な測定工具をすべて持参するようにしてください。修理スケジュールと補償プロセスの書面による計画も必要です。今週末までに送っていただけますか？）
🧑🎓【Student / Design Engineer】:
Yes, I will prepare the detailed plan and send it to you by the end of the week. The plan will include the inspection method, repair timeline, and the compensation procedure if our design is responsible. Thank you for your patience. We will resolve this issue as soon as possible.
（はい、詳細な計画を準備し、今週末までにお送りします。計画には検査方法、修理スケジュール、および当社の設計に責任がある場合の補償手順が含まれます。お待ちいただきありがとうございます。できるだけ早くこの問題を解決いたします。）
👨💼【Teacher / Ship Owner】:
Thank you. I look forward to receiving your plan. Please keep me updated on the progress. We need this resolved before the vessel starts commercial operation next month.
（ありがとうございます。計画の受領を楽しみにしています。進捗状況を随時お知らせください。来月に本船が商業運航を開始する前に、これを解決する必要があります。）
