Shipping company fits fuel switch

The GL type approved DS MKII is claimed to provide a reliable solution to problems caused by incorrectly performed changeover between high sulphur HFO and low sulphur distillate fuels. After the first on-board test, Jo Tankers decided to fit the DS MKII to nine existing vessels, in addition to newbuilding projects in Korea.

The DS MKII is claimed to provide a controlled, safe and reliable change-over from HFO to MDO/MGO and vice versa, as well as a safe blend fuel operation whenever required. The system can be used for both main engines and auxiliaries. The software controls a specially designed blend fuel valve and the unit can be adapted to the available space on board, which according to Jowa can sometimes prove to be very limited in case of retrofits.

The company says that the DS MKII gives a rapid and noticeable return on investment. “We are very pleased with the easy and quick retrofit installation of the system into the existing fuel systems on board”, says Jo Tankers fleet manager Andrew Hills. “We now know that we meet the strict sulphur levels requested in the SECA Areas and in other environmentally controlled areas. They can be reached both by using the Diesel Switch DS MKII for a complete change-over or for running on blend fuel. We appreciate the software feature including the history log for change-over and/or blend fuel procedures performed. This saves us time and money, but it is also advantageous for the environment. To protect the environment as much as possible is very important, both for us as a responsible shipping company, as well as for our customers.”
