Since 1935 Scully has been setting standards in tank filling safety. Our systems provide static grounding protection, prevent spills, and ensure safe loading in everything from rail tank cars, tank trucks, and storage tanks. There are a number of different options available to ensure safe transfer of hazardous liquids into rail tank cars.
For extra loading safety, Scully also offers the ST-15 Overfill Prevention Control Unit and portable Cane Sensor for top loading spill protection. For multiple, single compartment tank cars, specify one Control Unit and Sensor per tank car.
Api rp 1007 loading and unloading
Based on these weaknesses, analysis improvement approaches for Swiss Split were developed considering the generic elements of the transport chain, starting from the transhipment to the unloading at the final destination. The loading of the containers at the seaport and the rail transport from the seaport to the hinterland terminal will still not be carried out by Swiss Split. Thus, the operational conditions and the costs for these parts remain unaffected.
Today two general types of rolling stock are used for Swiss Split: standard flat wagons with wooden floors and conventional container wagons. Both types include two and four axle versions. The big difference between these vehicle types is that container wagons have no floor. This means loading and unloading equipment (e.g., forklifts) is unable to operate on these container wagons. Thus, additional equipment such as moveable ramps is required to load/unload the containers. Therefore a moveable ramp replaces the missing floor of the container wagons.
The type of wagon which is used depends on the technical equipment that is available for the unloading of containers at the destination sidings. Larger sidings are generally equipped with specific loading equipment to load and unload the containers. These sidings can be served with container wagons. On the other hand, smaller sidings often only have forklifts or industrial trucks available to unload containers. These vehicles need a continuous floor to operate on the wagon. Therefore, these sidings can only be served by conventional flat wagons.
As part of the ViWaS project, new wagon designs were developed for Swiss Split. The new wagons were designed to improve both the loading/unloading process on sidings and the transhipment process in terminals. The goal was to improve the service without increasing wagon-costs.
In the next steps additional modules like a surveillance of the load status of the wagon, sensors to detect condition of the payload, weight sensors to measure the axle loads or equipment for automatic brake tests will be integrated. This will support the goal to reduce the staff required at sidings and regional stations. The loading platform will be equipped with a GPS module, too. Thus, the risk of a loss or theft of the platforms is reduced by far.
If you have circular dependencies, which is very common for example when you are dealing with reloading a package, you must unload all the modules in the group in one go. You can't do this with reload() because it will re-import each module before its dependencies have been refreshed, allowing old references to creep into new modules.
Note that this will not work if the GC is turned off, or if reloading data that's not monitored by the GC. If you don't want to mess with the GC, the original answer might be enough for you. 2ff7e9595c
