Did you know
- The Wärtsilä Sulzer RTA84C was introduced in 1988, specifically designed to meet the demands of large container ships. It was developed from the earlier RTA84 model.
- The RTA84C is part of the broader RTA series, which began in 1981. It sits within the RTA-C family, which also includes the larger RTA96C, introduced in 1994 to address the need for even higher power outputs for future container ships.
- The RTA84C was chosen for its high power output at optimal shaft speeds, competitive cost, and economical fuel consumption across its operating range. It also offered reliability and durability, leading to low maintenance costs and extended times between overhauls.
