汇舸环保集装箱氮气实船应用

近日，汇舸环保自主研发的箱式氮气发生系统成功装船交付，该系统全部一体化集成在经船级社认证的标准尺寸集装箱内，从而允许和普通货物箱一起进行堆叠和运输。同时，整机采用空冷防爆设计，无需外接冷却水和其余船舶改装，插电即用（可配备集装箱发电机实现自供电），且出口氮气指标达到流量550Nm³/h、纯度97%、露点-60℃，具备惰化和除气双模式。其移动便捷、部署灵活、操作独立的特点能够满足大部分B型仓和有临时氮气使用需求的工作场景，例如，在船舶燃料仓进行维保之前，预先将箱式氮气系统吊运至船上，实现在船舶航行过程中提前完成仓室的惰化和换气，从而确保船舶进坞后能够立即开展维保工作。

汇舸环保作为一家全球领先的船舶环保设备及系统供应商，在船用氮气发生系统领域有着深厚的技术积累和丰富的业绩经验，其变压吸附式（PSA）和膜式氮气发生系统也已广泛受到市场青睐，近三年来总订单量已突破百台套，其中，油轮和化学品船订单量占51%，多采用大型PSA式氮气系统，流量最大达到4500Nm³/h，已在2024年开始陆续交付；集装箱及其余船型订单量占49%，多采用膜式氮气系统，某知名航运公司仅在2022年12月份就向汇舸环保采购了40台套膜式氮气系统，目前该项目部分船也已成功交付。此外，由氮气发生系统衍生的高压氮气增压机、DBB阀组、高压气瓶单元及PV breaker等产品，汇舸环保都能提供一站式解决方案及配套服务。

该产品之所以能在短期内快速发展，离不开其独有的设计和产品自身的优势，整个系统内的关键设备如空压机、中空纤维膜、程控阀门等部件均采用欧洲一线品牌，结合汇舸环保独有的工艺设计，不仅能够降低系统整体空耗和能耗，也保证了系统的稳定性。同时，汇舸环保还在氮气系统上添加了Playback和Troubleshooting等功能，能够实时回放存储数据并且进行远程监控，大大提高了售后问题的处理效率。

未来，随着IMO对绿色航运环保要求的不断提高，传统惰气系统将逐渐被氮气发生系统所取代，各类新燃料船舶的增加也将进一步推动氮气发生系统的应用。汇舸环保也将围绕集团“推动绿色能源，保护蓝色地球”的理念，持续推动船用氮气发生系统的智能化和绿色化发展，致力于成为船用氮气行业领先的系统供应商。

Recently, ContiOcean successfully delivered its self-developed containerized nitrogen generation system onboard.This system is fully integrated into a standard-sized container certified by classification societies, allowing it to be transported and stacked like regular cargo containers. The system features air-cooled and explosion-proof designs, requiring no external cooling water or modifications. It is plug-and-play (with the option to equip a containerized generator for self-supply) and delivers nitrogen with performance indicators of 550 Nm³/h flow rate, 97% purity, and -60°C dew point. It supports dual modes for inerting and degassing. With its mobility, flexible deployment, and independent operation, the system is well-suited for most Type B tanks and scenarios requiring temporary nitrogen supply. For instance, the system can be hoisted onto the vessel before fuel tank maintenance, allowing inerting and degassing of the tank during the voyage and enabling immediate maintenance upon docking.

As a globally leading supplier of marine environmental equipment and systems, ContiOcean has extensive technical expertise and experience in marine nitrogen generation systems.Its pressure swing adsorption (PSA) and membrane-based nitrogen systems have also gained significant market recognition. Over the past three years, total orders have exceeded 100 units. Of these, 51% were for oil tankers and chemical carriers, predominantly featuring large PSA systems with a maximum flow rate of 4,500 Nm³/h, which began delivery in 2024. The remaining 49% were for container and other vessel types, mainly adopting membrane-based nitrogen systems. For example, a leading global shipping company procured 40 units of membrane nitrogen systems from ContiOcean in December 2022, with some ships in this project already successfully delivered. Additionally, ContiOcean offers one-stop solutions and supporting services for auxiliary products derived from nitrogen generation systems, such as high-pressure nitrogen boosters, DBB valve assemblies, high-pressure cylinder units, and PV breakers.

The rapid development of this product is attributed to its unique design and inherent advantages. Key components within the system, such as compressors, hollow fiber membranes, and automated control valves, are sourced from leading European brands. Combined with ContiOcean's proprietary design, this ensures reduced system air consumption and energy consumption while maintaining stability. Furthermore, the nitrogen systems are equipped with Playback and Troubleshooting functions, enabling real-time data playback, storage, and remote monitoring. These features significantly improve efficiency in addressing after-sales issues.

Looking ahead, as the IMO continues to enforce stricter green shipping and environmental regulations, traditional inert gas systems will gradually be replaced by nitrogen generation systems. The rise of alternative fuel ships will further drive the application of nitrogen systems. ContiOcean will adhere to its mission of “Promoting Green Energy, Protecting the Blue Planet,” striving to advance the intelligence and eco-friendliness of marine nitrogen generation systems and solidifying its position as a leading supplier in the marine nitrogen industry.
