当客户NAFTO需要运输德国卢纳道达尔炼油厂的一个旧加热器时，他们向Sarens寻求协助。2021年5月至6月，Sarens成功将580吨加热器从生产现场转移到拆除区。此外，Sarens还分别运输了一个旧浸水器、一个新浸水器以及两个管架。

When customer NAFTO needed to transport an old heater at the Total refinery in Leuna, Germany, they turned to Sarens for help. From May to June 2021, Sarens successfully moved the 580-tonne heater from the production site to a dismantling area. In addition, Sarens also transported an old soaker, new soaker, and two pipe racks.
旧加热器的运输作业标志了德国中部道达尔炼油厂改造的一个重要里程碑。这个项目涉及到许多来自不同国家的不同的人，他们将一同来协调运作。此外，这次恰逢新冠疫情的开始，导致会议延误，不仅需要重新安排会议时间，还需要重新安排运输操作。

The transport of the old heater marked a critical milestone for the turnaround of Total Refinery Mitteldeutschland Leuna. The project involved many different people from different countries, all working together to coordinate the operation. It also happened to coincide with the beginnings of the Covid-19 pandemic, leading to delays and the necessity of rescheduling not only meetings, but transport operations.
由于支撑旧加热器的混凝土立柱之间的空间有限，因此必须设计一种特殊的SPMT结构。这种解决方案创造出了一种独特的SPMT配置，其中包括一个K24ST 12轴平板车、一个PPU和一个K24ST 10轴拉伸平板车。拉伸平板车被分成两半，每半轴部分用机械连接块串联至中心12轴线平板车的每一侧。

Because the concrete columns supporting the old heater provided limited space between columns, a special SPMT configuration had to be engineered. This solution resulted in a unique SPMT configuration consisting of a K24ST 12L trailer and PPU combined with a K24ST 10L stretch trailer. The stretch trailer was split in half, with each half connected to a side of the centre 12L trailer with mechanical coupling blocks.
另外，由于支撑旧加热器的混凝土立柱位于平板车的机械连接块和液压软管的路径上，需要逐步插入平板车。当他们在加热器下面逐步前进的过程中，四名Sarens机组成员必须断开并重新连接连接块和软管。

Moreover, since the concrete columns supporting the old heater were in the path of the trailers’ mechanical coupling blocks and hydraulic hoses, the trailer needed to be inserted step by step. The four-member Sarens crew would have to disconnect and reconnect the coupling blocks and hoses as they progressed underneath the heater.
必要的设备包括SPMT和辅助设备，期间通过6辆卡车从Sarens总部运抵项目现场，总行程为700公里。卸载和组装特殊的SPMT拉伸结构花费了两天的时间。

The necessary equipment, including SPMTs and auxiliaries, was brought to the project site from Sarens HQ via six trucks that travelled a distance of 700 km. Offloading and assembling the special SPMT stretch configuration took two days.
由于这是在重要的炼油厂改造过程中首次使用此SPMT配置，因此确保SPMT工况不会出现任何故障或零部件丢失是非常重要的。为了确保顺利运行，Sarens在总部组织了一个测试SPMT的装置，在将设备运至现场之前完成检查所有部件和功能。

Because this was a first-time SPMT configuration to be used during an important refinery turnaround, it was important for the SPMT configuration to perform without any failures or missing parts. To ensure a smooth operation, Sarens organised a test SPMT set-up at headquarters, checking all parts and functionalities before mobilising the equipment to the site.



等设备抵达Leuna炼油厂，SPMT就被部署至旧加热器的下面，用来承载混凝土支撑柱的重量。为运输腾出空间，客户随后拆除了这些立柱。此次的拆除工作非常小心，主要是为不损坏装载的SPMT。

Once the equipment reached the Leuna refinery, the SPMTs were installed underneath the old heater, taking over the weight from the concrete support columns. The client then demolished the columns to make way for transportation to commence. This demolition was performed with extreme care so as not to damage the loaded SPMTs.
移除立柱后，Sarens小心翼翼地将加热器运出了生产区域，周围脚手架的两边只有几厘米的空间。由于货物的重心很高，因此在运输前已经进行了路线研究，以确保所有障碍都被清除，道路被关闭，以防止冲突。运输过程中没有任何中断，最终加热器被安全顺利地运抵了拆卸区。

With the columns removed, Sarens carefully drove the heater out of its production zone with mere centimetres of space on each side of the surrounding scaffolding. Because the cargo had a high centre of gravity, a route study had been done before transport to make sure all obstacles were removed and roads closed to prevent clashes. The transport proceeded without any disruptions, bringing the heater safely and successfully to the dismantling area.
波兰NAFTO公司的项目经理Krysztof Batory说:“你们对加热器的移除运输，让运输看起来十分的容易。”

“You made the transport seem so easy, driving the heater out of its place,” said Krysztof Batory, project manager for NAFTO Poland.
Sarens对成功完成该项目感到自豪，特别是在一个繁忙的改造时段，期间约3000名工人和许多承包商在同一地点工作，并在不断变化的新冠疫情期间采用了新的安全管理举措。Sarens技术项目负责人Matthias De Weerdt补充到:“由于Sarens与NAFTO的成功合作，该项目得以顺利实施，对此我们非常感谢NAFTO。”

Sarens was proud to complete this project successfully, especially during a busy turnaround with approximately 3.000 workers and many contractors working on the same site and adopting new safety procedures during an evolving Covid-19 pandemic. Matthias De Weerdt, Technical Project Leader, Sarens adds, "The smooth execution of the project was possible due to the successful cooperation between Sarens and NAFTO for which we are very thankful to NAFTO."
