The software employed by the DS MKII, developed by JOWA Technology, controls a specially designed blend fuel valve that provides a controlled 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 auxiliary engines, and is type-approved by Germanischer Lloyd.
After initial on-board testing was successful, Jo Tankers has decided to install the DS MKII on nine more vessels, as well as adding the technology to its new building projects in Korea.
“We are very pleased with the easy and quick retrofit installation of the system into the existing fuel systems on board,” said Andrew Hills, fleet manager at Jo Tankers.
“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.”
