What KST Maritime does
KST Maritime Pte Ltd is a Singapore-based harbour towage and maritime services company founded in 1991. It operates a fleet of 61 Azimuth Stern Drive (ASD) harbour tugs ranging from 3,000 to 6,700 BHP, providing berthing and unberthing, coastal and escort towage, offshore support, ship-to-ship operations, firefighting, salvage, oil spill response, and emergency response services in the Port of Singapore and — through its Malaysian joint venture KSP Towage Sdn Bhd (formed 2003 with Straits Perkasa Services) — in major Malaysian ports and oil/gas terminals. The fleet is set to grow to roughly 78 vessels following the April 2026 acquisition of Seatrium's 17-tugboat fleet for S$104 million.
The company's customer base is enterprise B2B, comprising oil majors, offshore contractors, FPSO/FSO and LNG terminal operators, vessel owners and charterers (tankers, bulk carriers, container liners, cruise liners), shipyards, and global shipping agencies. The technology stack is fundamentally physical — modern ASD propulsion for high manoeuvrability and reduced service time — augmented by an integrated HSEQ management system certified to ISO 9001, ISO 14001, ISO 45001, and bizSAFE Star. There is no public pricing; contracts are bespoke enterprise agreements typical of port towage.
KST Maritime became a wholly-owned subsidiary of MedTug, a Mediterranean harbour towage leader, in 2022, after original shareholders Keppel Shipyard Investments and Smit Singapore divested. The MedTug group provides the only European towage platform in the Far East, with affiliate Maju Maritime operating alongside KST at the same Singapore head office. The company is privately held, headquartered at 460 Alexandra Road, Singapore, with 51-100 employees and 24/7 operations.

KST Maritime competitors and assessment
Company assessmentRegional players
- Wilson Sons: Brazilian integrated port and maritime operator with a substantial harbour towage division serving Brazilian and South American ports. Comparable to KST as a regional towage provider with a captive home-port advantage and similar vessel classes.
- Vallianz Holdings: Singapore-based offshore support vessel operator focused on Asia-Pacific oil and gas customers. Vallianz overlaps with KST's offshore support service module but is more exposed to long-term O&G charter contracts rather than port harbour towage.
- PACC Offshore Services: Singapore-listed offshore support vessel operator serving similar Asia-Pacific oil major customers. PACC overlaps with KST Maritime on offshore support for FPSO/FSO and platform operators but does not compete in core harbour towage.
Direct peers
- Svitzer: Global harbour towage leader and A.P. Moller-Maersk subsidiary, operating a large fleet of harbour tugs across major ports worldwide. Svitzer competes head-to-head with KST Maritime in Singapore and provides a directly comparable towage business model centered on ship assist, berthing, and escort services.
- Fairplay Towage: Pan-European harbour towage operator with presence in Spain, Germany, the Netherlands, and the Baltic. Direct comparable to KST Maritime's parent MedTug in size, fleet composition, and port-centric service model.
- Boluda Towage: European harbour towage specialist spun out of Boluda Corporation with operations across Iberia, West Africa, and Latin America. Highly comparable as a focused harbour towage player with international expansion strategy similar to MedTug's KST platform.
- SAAM S.A. Latin American port operator and tug provider with a large fleet of harbour tugs across the Americas. SAAM directly parallels MedTug/KST Maritime's model as a regional harbour towage specialist with growing international ambitions beyond its home region.
- PSA Marine: Singapore port operator PSA's wholly-owned marine services arm, providing harbour towage, pilotage coordination, and vessel traffic services in Singapore. PSA Marine is the largest domestic harbour towage competitor to KST Maritime, sharing the same primary customer base of vessel owners calling at PSA terminals.
- Boskalis (Smit Towage): Dutch maritime services group with a substantial global harbour towage business historically known as Smit Towage. Boskalis is highly comparable to KST Maritime as a major international towage operator with comparable vessel ranges and operating geographies.
Broad incumbents
- Tidewater Inc. Global offshore support vessel (OSV) operator with a large fleet of anchor handling tugs, platform supply vessels, and crew boats. Tidewater is a broader incumbent that overlaps with KST's offshore support segment (FPSO/FSO and platform assistance) but operates at a different scale and in deeper-water segments.
