NEW RAL-DESIGNED TUG FOR SUEZ CANAL DUTY

NEW RAL-DESIGNED TUG FOR SUEZ CANAL DUTY

Friday, November 26, 2021 

The first RAstar 2800-CL ASD escort tug, 'Svitzer Suez 1', designed by Robert Allan Ltd (RAL) of Canada and built by Cheoy Lee Shipyards, has been delivered to Svitzer Egypt LLC and will soon commence operations in the Suez Canal.

Svitzer is the first owner of this new escort tug design and a further nine tugs to this design have already been ordered with Cheoy Lee. One of the primary goals of the fresh design was to make it extremely flexible allowing for various propulsion machinery options, IMO Tier III solutions, deck machinery choices, accommodation layouts, etc. all with minimal impact on the overall design. This was to allow Cheoy Lee to easily offer customized solutions to clients even at a relatively late stage in the construction process. The hull form has the proven sponsoned shape typical of all RAstar designs and was refined and tested using CFD to ensure the desired free running performance, manoeuvrability, and escort performance characteristics. The superstructure has a low profile for working under the flare of attended vessels. Design work was completed to ensure compliance with all the major classification societies’ rules, and it exceeds many flag and/or owner specific safety requirements.

The first 28.4m RAstar 2800-CL design was constructed to Lloyd’s Register rules with notation: ✠100A1 Escort Tug, Fire Fighting 1 with Water Spray, ✠LMC, ✠UMS, IWS.

Main propulsion comprises a pair of CAT 3516C diesel engines, each rated at 2350 kW at 1800 rpm, and each driving a Kongsberg model US 255S P30 Fixed Pitch Z-drive. The electrical plant comprises two identical Caterpillar C 7.1 diesel gen-sets each with a power output of 118 kWe.

On trials, the Svitzer Suez 1 exceeded performance expectations, recording bollard pull of 82.1t, 77.6t, and a free running speed, ahead, of 13.3 knots

While Svitzer Suez 1 is the first of the line, RAL says it is already clear that this design will be popular with operators, citing the initial orders for ten of this entirely new escort tug as testaments to the confidence in RAL's design capabilities and the build capabilities of Cheoy Lee Shipyards.
