Port Klang is the principal port of Malaysia on the Strait of Malacca. Known during colonial times as Port Swettenham, it was renamed Port Klang in July 1972 and has since become the largest port in the country. It is located about 6 kilometers southwest of the town of Klang, and 38 kilometers southwest of Kuala Lumpur.
Port Klang was also known as the National Load Centre.
Located in the District of Klang, it was the 14th busiest container port (2022) in the world. It was also the 12th busiest port in by volume (million TEU) in 2018 and as of July 2020 was the top location for aluminum stockholding for LME, the top metal exchange in the world.
South Port has a wharf with 8 berths. Berths are identified by English numerals and alphabets, which may range from English numerals 1 to 7A with English alphabets. There are three types of cargo unloading and loading facilities at the wharf, namely liquid cargo, bulk cargo and breakbulk cargo. The wharf has infrastructure for handling liquid cargoes at berths 1 and 2, bulk cargoes at berth 3 and breakbulk cargoes at remaining berths.
The port has two types of anchorage within the port limits, outer anchorage and inner anchorage. There is one outer anchorage each seaward of the South Channel and the North Channel, which are identified as Outer Anchorage South Channel and Outer Anchorage North Channel. The Outer Anchorage South Channel lies in the Pintu Gedong area to the east and southeast of the South Fairway Buoy, where ships anchor awaiting berthing instructions, and also for ship to ship transfer (STS) activities. However, anchoring of vessels within 1 nautical mile 1.9 km radius of the South Fairway Buoy is prohibited. On the other hand, The Outer Anchorage North Channel is the recommended anchorage for vessels waiting for pilots about 0.5 nautical miles (0.93 km) before the pilot boarding ground, where the water depths is 15–22 metres (49–72 ft).
