East Kalimantan → Koh Sichang freight planning
This is a commercially identifiable Southeast Asian thermal-coal route rather than a manufactured SEO combination. S&P Global states that its Southeast Asia Thermal Coal marker uses a same-day dry-bulk freight assessment for East Kalimantan to Koh Sichang on a 55,000 mt Supramax basis.
Use Supramax or Ultramax as the first comparison for a ~55kt stem, then test laycan, port time and bunker assumptions in the CharterPulse estimator.
What moves the freight number?
Owner positioning, exact Kalimantan loading location, loading method, draft, laycan, bunker level, Thai discharge terms, cargo quantity and port productivity can materially alter the final rate. A modeled voyage therefore should be treated as a planning range until checked against current tonnage and owner ideas.
Suggested workflow
Start with 55,000 MT, compare Supramax and Ultramax, adjust port time and bunker basis, then use the WhatsApp market-check handoff from the estimator. The handoff preserves the route, cargo and planning class so a broker does not need to reconstruct the requirement.
