RAstar 4000 DF

Among the most high-performance escort tugs in the world with the ability to generate indirect forces of approximately 200 tonnes, the RAstar 4000-DF (dual fuel) tugs are part of the new generation of increasingly environmentally-friendly, yet powerful tugboats from Sanmar.

The tugs have been designed by Vancouver-based Robert Allan Ltd. (RAL). The larger RAstar 4000 DF vessels will be the most powerful Azimuth Stern Drive (ASD) escort tugs on Canada’s west coast, and will rank among the world’s highest-performing escort tugs.Measuring 40.2m LOA, with a 16m beam and maximum draft of 7.4m, these extremely strong tugs can achieve an impressive maximum bollard pull of 100 tonnes, and are designed to operate effectively with optimal efficiency in even the most demanding conditions.

Capable of running on either diesel or LNG, the tugs earn their green credentials by featuring a diesel exhaust after-treatment system in full compliance with IMO Tier III emissions standards, the most stringent such standard in existence for the international marine industry and, in a major advance towards a sustainable future, by the ability to perform the entirety of long-distance escort missions using only LNG, dramatically cutting emissions, in particular of CO2, compared to even Tier III standards.

The RAstar 4000 DF escort tugs will perform the majority of their missions using natural gas as their primary fuel. This allows major emissions reductions compared to conventional diesel tugs of the same power, in compliance with the most stringent emissions standards in the international marine industry. In addition to these environmental benchmarks, the escort tugs will be capable of pollution response/oil spill recovery, fire fighting of marine terminal fires, person overboard response, and emergency towage of vessels.
