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.
