While owners have long recognized the link between clean hulls and lower fuel costs, lack of reliable data has slowed investments in optimizing hull performance. But with improved sensor technologies and data analysis tools, hull performance is getting a second look. Owners seeking to lower fuel costs and comply with pending regulations on emissions and invasive species often look to equipment manufacturers to meet their needs. From new efficient engine designs to alternative fuels, scrubbers to ballast water treatments systems, owners face some expensive decisions.

Wärtsilä Introduces Upgraded RT-flex50 Engines

Wärtsilä has introduced a new, "-D" version of its RT-flex50 low-speed marine engine type with a higher power rating and lower fuel consumption compared with the existing "-B" version. The maximum continuous power output of the RT-flex50 has been raised by 5.1% from 1660 to 1745 kW/cylinder (2260 to 2375 bhp/cylinder) in the "-D" version at the same running speed of 124 rpm. Thus, with five to eight cylinders in-line, the RT-flex50 in the "-D" version covers a power range of 6100-13,960 kW (8300-19,000 bhp) at 99-124 rpm. At the same time the brake specific fuel consumptions (BSFC) have been reduced by 2 g/kWh. Thus at the maximum continuous rating R1, the full-load BSFC has been reduced from 171 to 169 g/kWh.
