Multi Ocean Shipyard (MOS), one of Southeast Asia's largest, anchors Tanjung Balai Karimun's port economy on Karimun Island (IDTJB), offering roughly 1,300 m of waterline and 10-15 m water depth for new-building, dry-docking, repair, and maintenance of vessels up to 50,000 DWT. Positioned in the Strait of Malacca southwest of Singapore and west of Batam, the port sits on one of the world's busiest shipping lanes. Designated anchorage areas let transiting vessels wait safely, while ship-to-ship bunker fuel supply is a core service here. Large-scale container or general cargo handling is not the port's focus — that role belongs to nearby Singapore and Batam. Tanjung Balai Karimun instead specialises in maritime services: repair, maintenance, and bunkering for ships passing through the strait.
