Inter-Island Cement Shipping: Lessons from the Khatulistiwa 8 Sinking
Inter-island cement shipping is back in focus after the cargo ship MV Khatulistiwa 8, carrying 1,850 tonnes of cement from the PT Semen Indonesia (SIG) special terminal in Tuban to Sampit, Central Kalimantan, collided with a sand barge and sank on the night of 7 October 2026. Seventeen of the 18 crew survived, one crew member was found dead three days later, and the cargo was lost. For building-material buyers outside Java, it is a reminder of the value of buffer stock, cargo insurance and suppliers with a back-up plan.
Timeline: an inter-island cement shipping voyage that ended on the seabed
According to the Directorate General of Sea Transportation at the Ministry of Transportation, the Indonesian-flagged ship left the SIG Tuban special terminal at 17:30 WIB. At about 21:37 WIB, the agent was told by the chief engineer that the ship had hit a sand-laden barge towed by the tug TB Berkat Bahari, about 9 nautical miles from the terminal, and that the forward hull was leaking. VTS Surabaya broadcast the information on radio Channel 16.
- Cargo: 1,850 tonnes of cement in polysling packaging, Tuban to Sampit.
- 23:07 WIB: 17 crew including the master were rescued by TB Amazon Harbour and taken to the SIG Tuban terminal.
- 23:45 WIB: the ship listed and sank; the cargo went down with it.
- Follow-up: the Tanjung Pakis harbour master (KSOP Class III) issued a Notice to Mariners, deployed patrol boat KNP 485 with Basarnas Brondong, and is monitoring possible pollution. The cause is still under investigation.
- 10 October 2026: Kompas.com reported that the chief officer, Mayan Petter Saba, was found dead about 2 miles south of the collision point. The ship was reported to belong to PT Elano Kusuma Shipping.
Why this matters to building-material buyers
Cement, tiles, steel and light steel for projects in Kalimantan, Sulawesi or eastern Indonesia usually travel by sea from plants and warehouses in Java. One lost ship means one cancelled delivery, and buyers at the destination must wait for the next vessel. We found no official report of cement supply disruption in Sampit after this accident, so this article does not claim a shortage. But the risk is real for any project that depends on a single shipment.
Practical steps for inter-island deliveries
- Buffer stock: do not schedule a concrete pour or installation on the day the ship is due; leave room for delays.
- Cargo insurance: ask whether the price includes marine insurance, who the insured party is and which documents a claim needs.
- Split shipments: for large volumes, consider several sailings so not all material is on one ship.
- Hand-over point: state in the contract when risk passes from seller to buyer (warehouse, loading port or project site).
- Packaging: bulk cement, jumbo bags and 40–50 kg sacks unload differently; check the equipment at the destination port.
