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.
The principal particulars of the Rasalkir 1 and its sisters, the Rasalkir 2, and Rasalkir 3 are as follows:
| Length BP Beam, Moulded Depth, Moulded Maximum Draft Power |
– 31.00 metres – 12.00 metres – 5.36 metres – 5.20 metres – 4720 kW total |
The vessels have been built and classed to American Bureau of Shipping notations:
A1, , Towing Vessel, Fire-fighting Vessel Class 1, 
AMS, ABCU, Unrestricted Navigation
The propulsion machinery consists of a pair of Yanmar 8EY26 medium speed diesels, each producing 2,360 kW at 750 rpm. This power is transmitted via two Kawasaki KST-220ZC/B Rexpellers. On trials, Ras Alkir 1, Ras Alkir 2 and Ras Alkir 3 met or exceeded all performance expectations with the following results:
| Bollard Pull Ahead Bollard Pull Astern Free running speed, at full RPM |
– 72 tonnes – 67 tonnes – 13.5 knots |
To enable extended endurance at sea, the vessel has the following tank capacities:
| Fuel Potable Water Ballast Foam Detergent / Dispersant Recovered Oil Oily Water Dirty Oil Sewage |
