Mr. Peter is from Liberia and is a professional contractor for construction projects in Liberia. On April 5th, 2021, we received an email from Peter. There is a river in Liberia as his working site, he wanted to pump sand from the river and used the sand for construction after treatment. He had contacted someone who would provide the sand pumping equipment for the filter. Now, he contacted us about the sand dredging machine.
After receiving the email, we sent an email confirming the detailed working condition to him. Because the engineers needed to know the specific detail to confirm the river sand pumping boat which we supplied is the most suitable type for the customer.
The detailed working condition was as follows:
According to the information Peter sent, the engineers recommended the 10-inch River Sand Mining Dredger for him, equipped with our 10-inch heavy-duty sand pump. The specification of the River Sand Mining Dredger is as follows:
In order to facilitate the operation and maintenance of customers, we have considered the following aspects in the design of the River Sand Mining Dredger:
After we sent the design specification of the River Sand Mining Dredger, Mr. Peter said they would need some time to consider and discuss it. On Apr. 15th, 2021, we received feedback from Peter again. He discussed with his engineers and operators to confirm the design whether was suitable for them and whether they could operate it smoothly. He also requested we contact the technician in the workshop who was responsible for loading. The loading engineer calculated the space of all the goods and confirmed that all the goods ordered by the customer could be loaded into 2* 40 HQ containers. After all of his questions has been answered, we signed the order. The total order included one set 10-inch River Sand Mining Dredger, one set propeller, 400m discharge PE pipes, and 30 pairs of floaters for some pipes. Then, we sent the PI with bank payment information together.
We received a 40% advance payment for the River Sand Pumping Machine from the customer on Apr. 20th. Then we arranged the production in our workshop. The production time we requested was 25 working days( till May 23). Finally, the River Sand Mining Dredger completed production in May. 20th. The River Sand Mining Dredger was finished as scheduled, then we did the running testing next. During the whole testing time, all the engines could be started smoothly and the pump was work well. So, we sent the testing video of the River Sand Mining Dredger to the customer. Mr. Peter was very satisfied with the testing video. On May. 21st, he paid the 60% balance and asked us to arrange the shipment. According to his requests, we booked the earliest containers and vessel for him on the 22nd. The shipping time is on May 29th, so we loaded the River Sand Mining Dredger on the 25th.
Then we charged the other things and confirmed the detailed information of the bill of loading. When all the detailed information was confirmed, we helped Peter do the necessary documents for customs clearance about this 10-inch river sand pumping boat and pipeline. After the vessel has left the port, we sent him the schedule for reference. " Nice service and professional support! Pleasant cooperation! Thanks for all the help and kindness!" Mr. Peter said.
