Wartsila power for Iran box ships
The six ships will each be equipped with a Sulzer 7RTA72U-B low-speed main engine, having a maximum continuous power of 21,560 kW at 99 rev/min. They will also each be supplied with three Wartsila diesel generating sets, two sets with Wartsila 8L20 engines each of 1,360 kW output at 900 rev/min, and the third set with a Wartsila 6L20 engine of 1,020 kW at the same speed.
The main engines will be built at Wartsila's Trieste factory in Italy while the generating sets will be manufactured at the Vaasa factory in Finland. Engine deliveries to the shipyards are due between July 2003 and February 2004.
To meet the delivery dates required by IRISL, four of the ships will be constructed by Aker MTW and two by Kvaerner Warnow Werft in Rostock-Warnemünde, Germany. Both yards are managed by Aker Kvaerner Yards. Delivery of all six vessels will be completed by mid 2004.
The ships are of the MTW 2500 type, with a length of 207.4 m and beam of 29.8 m. They have stowage for 2478 TEU with 200 reefer sockets. The ships' service speed is 22.3 knots on a design draft of 10.1 m.
This latest order will bring to 16 the number of containerships of this design with Sulzer 7RTA72U-B main engines and Wartsila 20 generating sets. A series of ten vessels with the same main engines and generating sets are under construction at Aker MTW with the first having been delivered in 2001.
