来自产业联盟SEA/LNG的一项研究表明，用液化天然气替代现有燃料的改装方案，是现有超大型原油运输船（VLCC）改装的最优解，它有利于船舶更好地应对将于2023年生效的环境新规。在该项研究中，SEA/LNG将三个改装方案进行了比较：

（1）改装为LNG燃料发动机

（2）使用重质燃油，加装脱硫塔

（3）使用超低硫燃油

依照碳强度指标评级，LNG组表现最好。研究预计，改装后的船舶将保持在B级，直到2027年才滑入C级，最终在2032年滑落至D级。考虑到今后可能会在航运业引入碳定价，使用液化天然气燃料的船东可能会得到财政补贴。

Retrofitting existing very large crude carriers(VLCC) to run on LNG as fuel has enormous benefits over alternative options to future-proof the ships from becoming obsolete as new environmental regulations take the stage in 2023, a new study from the multi-sector industry coalition SEA/LNG claims. In the study, compared three scenarios in an investment case study,  including an LNG retrofit, a scrubber-fitted VLCC running on heavy fuel oil, and a conventional VLCC sailing on very low sulphur fuel oil(VLSFO). When it comes to meeting the Carbon Intensity Index(CII), LNG performs best, it would maintain rating B until it slides into C mid-2027 before finally slipping to D in 2032. LNG retrofit offers financial incentives to ship owners with regard to future fuel prices, especially taking into account the likely introduction of carbon pricing in shipping.

新加坡港和鹿特丹港是世界上最大的燃料加注港，也是亚欧航线上的重要枢纽。为助力高效、可持续的航运发展，新加坡海事及港务管理局（MPA）和鹿特丹港务局签署了一份合作备忘录（MoU），以建设世界上最长的绿色数字航运走廊。两国港务局将与航运公司、燃料供应商以及其他相关企业组成广泛的联盟，共同应对替代燃料在成本、可用性、安全性以及航程限制等方面面临的挑战。此外，该谅解备忘录还希望通过创建共享数据、电子文件和标准的数字贸易通道，优化海上效率，实现安全和透明的货物流动。

Maritime and Port Authority of Singapore and Port of Rotterdam to establish world’s longest Green and Digital Corridor for efficient and sustainable shippingSingapore and Rotterdam are among the largest bunkering ports in the world, making them vital links on the Asian-European shipping lanes. Each alternative fuel has its own challenges relating to costs, availability, safety, and restrictions in range. To tackle these challenges, the two port authorities agreed to bring together a broad coalition of shippers, fuel suppliers and other companies to collectively work on potential solutions. Beyond alternative fuels, the MoU also aims to optimise maritime efficiency, safety, and the transparent flow of goods by creating a digital trade lane where relevant data, electronic documentation and standards are shared.
