GTT 最新的 200,000 立方米液化天然气运输船概念

关于 GTT 最新的 200,000 立方米液化天然气运输船的设计，该设计具有慢速航行和三个货舱的特点。我们向英国劳氏全球天然气部门总监 Panos Mitrou 提出的 3 个问题

3 questions to Panos Mitrou, Global Gas Segment Director, at Lloyd’s Register, on GTT’s latest  200,000 m³ LNGC design featuring slow-steaming navigation and integrating three-cargo tank.

您能否详细说明劳氏船级社认为在授予GTT提出的200000立方米液化天然气运输船（LNGC）概念的AIP时最关键的具体因素，特别是与传统的174k四罐设计相比？

Can you elaborate on the specific factors Lloyd's Register considered most critical in granting the AIP for the 200,000 m³ LNG carrier (LNGC) concept proposed by GTT, especially compared to traditional 174k four-tank designs?

GTT 的 200,000 m³ 液化天然气运输船的原始概念是一个大胆的设计，具有三个相同的货舱，而不是传统的四个。这种结构变化需要确保储罐在增加的晃荡载荷下的完整性。对于该 AiP，劳氏船级社根据严格的船级标准和 IGC 规范要求仔细评估了货舱设计的稳健性。我们对各种 GTT 围护系统（Mark III Flex、Mark III Flex+、NO96 Super+ 和 GTT Next1）进行了全面评估，并确认该设计符合所有安全和性能标准。该评估强调了 GTT 概念的核心创新，提供前瞻性的解决方案，以满足行业对 LNG 运输效率和安全性不断变化的需求。

The original concept of GTT’s 200,000 m³ LNGC is a bold step, featuring three identical cargo tanks instead of the traditional four. This structural change requires ensuring tank integrity under increased sloshing loads. For this AiP, Lloyd’s Register carefully assessed the robustness of the cargo tank design against strict class standards and the IGC Code requirements. We conducted a comprehensive evaluation across various GTT containment systems - Mark III Flex, Mark III Flex+, NO96 Super+, and GTT Next1 - and confirmed that the design meets all safety and performance criteria. This assessment underscores the innovation at the heart of GTT’s concept, offering a forward-thinking solution that meets the industry’s evolving demands for both efficiency and safety in LNG transport.

劳氏船级社认为，在这种设计中，预期的环境和运营效益最显著的是什么？

What are the anticipated environmental and operational benefits that Lloyd’s Register sees as most significant in this design?

在劳氏商业咨询公司对 GTT 的计算结果进行验证后，与标准 174k 船舶相比，评估了 200k 概念的排放强度、单位货运成本 （UFC） 和潜在的监管优势。升级到 200k 船舶具有环境和经济优势：在 EU ETS 和 FuelEU 等框架下，到 2035 年，基于航行的排放强度可以降低 ~20%，UFC 最多可降低 5%，到 2050 年可降低 14%。这些发现表明，扩大舱容不仅可以提高运营效率，还可以为未来提供强大的商业和合规战略。通过与监管趋势保持一致并降低成本，这种大型船舶概念使运营商能够有效地满足长期的环境和财务要求。

Following Lloyd’s Register Business Advisory verification of GTT’s calculations, the 200k concept was evaluated for emissions intensity, Unit Freight Cost (UFC), and potential regulatory benefits versus a standard 174k vessel. Upsizing to a 200k vessel offers environmental and economic advantages: voyage-based emissions intensity can be reduced by ~20%, and UFC by up to 5% by 2035 and 14% by 2050 under frameworks like EU ETS and FuelEU. These findings illustrate how upsizing not only enhances operational efficiency but also provides a powerful commercial and compliance strategy for the future. By aligning with regulatory trends and reducing costs, this larger vessel concept positions operators to navigate long-term environmental and financial requirements effectively.

劳氏船级社如何看待这一创新对更广泛的液化天然气航运业的影响，特别是对大容量运输船未来的燃油效率和减排标准的影响？

How does Lloyd's Register envision this innovation impacting the broader LNG shipping industry, especially regarding future standards for fuel efficiency and emissions reduction in large-capacity carriers?

尺寸和，比其重要的速度两个参数都是直接影响排放强度的关键参数，但由于传统的行业规范，在 LNG 运输船设计中被忽视了。从排放的角度来看，速度是最重要的参数。在当今的能源转型中，保持 19.5 节的速度已不再可行。这种新设计表明，通过挑战传统思维，我们可以在不牺牲运输能力的情况下将排放强度降低 27%。正如船舶推进方面从蒸汽燃机转向 四 冲程电力推进，然后转向两冲程发动机一样，这一概念代表了液化天然气运输船潜在的下一个技术飞跃。其增强的性能和合规性降低了监管风险，为其他进步创造了时间窗口，例如替代燃料和碳捕获系统，以达到完全成熟。然而，最重要的是，它解决了投资风险，这是液化天然气行业进一步增长的主要障碍。

Size and, more importantly, speed, are key parameters that directly impact emissions intensity but have been overlooked in LNG carrier design due to traditional sector norms. From an emissions perspective, speed is the most significant parameter. In today’s energy transition, maintaining speeds of 19.5 knots is no longer viable. This new design demonstrates that by challenging conventional thinking, we can reduce emission intensity by 27% without sacrificing transport capacity. Just as the industry moved from steam to 4-stroke electric propulsion, and then to 2-stroke engines, this concept represents the potential next technological leap for LNGCs. Its enhanced performance and regulatory compliance mitigates regulatory risk, creating a time window for other advancements, such as alternative fuels and on-board carbon capture systems to reach full maturity. Above all, however, it addresses investment risk, a key barrier to further growth of the LNG sector.
