In South Korea, KCTC used a 324-axle SPMT to move a naval block of 14,754.19 tons, surpassing the previous mark by Lamprell and entering the Guinness World Records.
A load of 14,754.19 tons took KCTC’s SPMT to the Guinness World Records in Goseong, South Korea, on June 23, 2016, by moving the largest individual naval block ever transported by this system. The article data is from KCTC and Guinness World Records.
World record with giant naval block
KCTC CO., Ltd., from the Republic of Korea, achieved the record for the heaviest load ever transported by self-propelled modular transporters, known as SPMTs. The recorded weight was 14,754.19 tons, equivalent to 16,263.71 US tons.
The transport was carried out in Goseong and entered the Guinness World Records list as the world’s largest heavy cargo transport vehicle. The feat involved a naval block manufactured at the Samkang MNT shipyard.

The block measured 110.5 meters in length, 50 meters in width, and 40 meters in height. With these dimensions and total weight, the structure was recognized as the largest individual naval block in the world at the time.

324-axle SPMT took the piece to the dock
To carry out the land movement, KCTC used a 324-axle SPMT, equipment specialized in transporting heavy loads. The operation took the naval block from the Samkang MNT shipyard to the dock.
After this stage, the same system was used to roll the block onto an 80,000-ton gross tonnage floating dock, which was moored on site. The process required controlled movement of the structure.
The operation marked the company’s entry into the Guinness Book of World Records for transporting the world’s heaviest load by self-propelled modular trailer. The official recognition took place on June 28, 2016.

From the floating dock to Jinhae Bay
After receiving the naval block, the floating dock was moved to Jinhae Bay with the support of a tugboat. Then, the block was launched into the bay using the dock’s own ballast capacity.
After the launch, the ship block was floated to a semi-submersible ship waiting nearby. This movement was also done with the help of a tugboat.
From this transfer, the structure proceeded by sea to Singapore. The route completed an operation that started at the shipyard, passed through the dock, and ended with the international shipment of the naval block.
KCTC surpassed Lamprell’s previous record
With the transport, KCTC broke the previous Guinness world record in the same category. The previous record was 13,191.98 tons and belonged to Lamprell.
The new record positioned the company as the global record holder for the heaviest load transported by SPMTs. For KCTC, the result also represented recognition of its capability in the heavy cargo transport sector.
The company presented the achievement as part of its challenges in innovative logistics services. The transport of the 14,754.19-ton naval block became the world reference in the category recognized by Guinness.
The case remains linked to the extreme use of logistical technology applied to giant naval structures.
