In preparation for the 2020 sulphur cap and to better manage switching between fuels, NYK and Nippon Yuka Kogyo an NYK Group company, have teamed with Horiba a Japanese specialist engineering organisation. to develop a new sulphur-in-oil analyser for ships. The new device is based on an existing device used at ashore.

Using this new analyser, NYK will be able to thoroughly comply with regulations limiting sulphur oxides (SOx) from vessels, as well as optimise the company’s use of low-sulphur fuel oil, the company said. In addition, the device can be used to better manage the switch between fuels with different characteristics when entering or leaving emission control areas.

Engineers must change to low-sulphur fuel before entering ECAs by calculating the time that the sulphur concentration in tanks and pipes will fall to 0.1% or less. This new easy-to-operate sulphur-in-oil analyser for ships has been developed to meet this demand.

NYK says the onboard Sulphur-in-oil Analyser can analyse a wide range of fuel, from C heavy oil to light oil. Maintaining the accuracy and reliability of onshore analysis centres, the compact new analyser uses disposable sample cells to keep clean, even in the engine room, and allows onboard engineers to confirm that the sulphur concentration in fuel is under 0.1% before entering an ECA.
