About us

KST Maritime PTE LTD

KST Maritime PTE LTD was established in 1991 under a joint venture between Keppel Shipyard Investments Pte Ltd, which is a part of Keppel Offshore & Marine under the umbrella of Keppel Corp, and Smit Singapore Pte Ltd, Which is a part of Royal Boskalis Westminster N.V. (“Boskalis”). In 2022 Rimorchiatori Mediterranei, the mediterrenan harbour towage leader, bought the 100% of the share of KST Maritime PTE LTD and became the first European operator in Far East.

Rimorchiatori Mediterranei has always been proud of staying on top of the service it provides, and has always been eager to fine-tune its operations to respond to customer’s needs. Our Group operates both in Italian ports (Genova, Salerno, Ravenna, Trieste, Ancona, Ortona, Vasto, Termoli, Pescara, Milazzo, Augusta, Catania, Pozzallo, Siracusa), in Malta, (Valletta, Marsaxlokk), in Norway (Floro), in Grecia (Atene), in Colombia (Santamarta), in Singapore and in Malaysia. Powerful and modern tugs are important factors which have contributed to improve tug maneuverability and reduced towing service time. This constant upgrading has always been a “priority” for the harbors in which the Group operates.


Today we own, manage and operate a versatile fleet of 73 highly manoeuvrable Azimuth Stern Drive (ASD) Harbour tugs ranging from 1,600 to 5,600 BHP which are capable handling any types and sizes of vessels. In Singapore alone, we have 24 tugs dedicated exclusively for harbour operations.
