The Saudi Port Authority has recently taken delivery of three Robert Allan designed RAmparts 3200-W tugs.
The tugs, named Rasalkir 1, Rasalkir 2 and Rasalkir 3, are powerful ship-handling/terminal support tugs designed to act as harbour, escort, pollution control and fire-fighting tugs, and will assist in mooring, unmooring and all maintenance requirements in the ports of the Kingdom of Saudi Arabia, in both the Red Sea and Arabian Gulf waters.

The tugs were constructed at Zamil Offshore Services in Saudi Arabia with close collaboration with Robert Allen naval architects to establish the final specification and vessel layout. The tugs hulls double chine form, with a sweeping chined stern, is reflective of the well-proven Robert Allen design. In addition the large escort skeg is fitted forward to enhance the indirect towing capability and to provide enhanced roll stability.
