Jo Tanker, a Norwegian ship owner, has reached changeover and blend fuel requirements by installing JOWA Technology Diesel Switch DS MKII. The switch is type-approved by Germanisches Lloyd and leads to meeting the sulphur emissions levels in CARB and SECA areas. The DS MKII Diesel Switch has been developed by Swedish-based Jowa Technology. According to the company it provides a reliable solution for the shipping industry. Incorrectly performed changeover will create both short-term, as well as long-term problems for crew, engine, environment and the owner. After the first on-board test, Jo Tankers was convinced by the positive results achieved by the JOWA Technology DS MKII Diesel Switch. This lead to the installation of the DS MKII in nine more vessels, in addition to new building projects in Korea. "Since we installed the DS MKII we have been experiencing very positive results onboard our vessels", says Fleet Manager Mr. Andrew Hills. The DS MKII provides 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, as well as for the auxiliary engines.The DS MKII has unique software developed by JOWA Technology, controlling a specially designed blend fuel valve and has an overall architecture that can be adapted to the available space on board, which sometimes can prove to be very limited in case of retrofits.
JOWA Technology says that the low-cost investment for the DS MKII gives a rapid and noticeable return on investment (ROI). “We are very pleased with the easy and quick retrofit installation of the system into the existing fuel systems on board”, Fleet Manager Mr. Andrew hills at Jo Tankers explains.
Another significant factor for Jo Tankers was environmental concern. Here, the investment in the Diesel Switch has resulted in a noticeable improvement. "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." After installing DSMKII, Jo Tankers has achieved automatically controlled, safe and economical optimized changeover procedures from HFO to MDO and vice versa.
