Singapore’s first duel-fueled tug has completed its first towage operation, successfully assisting a vessel to unberth in the Port of Singapore.

The 50-tonne bollard pull harbor tug PSA Aspen was built by Robert Kuok-backed shipbuilder PaxOcean in China and recently arrived in Singapore.

Designed by Robert Allan, the tug is equipped to operate in either diesel or LNG mode and is compliant with IMO emission requirements.
