Present Condition of Heavy Marine Fuel from Point of View of Shipping Company
By Takashi Shiotsu, Toshikazu Takase, Yoshikazu Nagai, Yasuhiro Kurose, Fumio Kawaguchi, Toshinori Moriwaki
We have had the recognition it is the first step of engine trouble preventive measures that properties of fuel oil are clear at the time of use based on the trade custom which quality of marine fuel oil does not have guaranteed and has transacted. Therefore, when the ship that we are operating supplies fuel oil in world each port, by picking a sample and analyzing it in our laboratory, it is made use of our ship in safe operation maintenance. For safe operation of a ship, we ask for making the best of in the production and distribution processes of heavy oil to the supplier, and from now on it is necessary as a user to continue a property investigation of supplied fuel oil.

Measurement of Lube Oil Consumption by Laser Displacement Detector
By Takahide Kawano, Hiromi Kondoh, Yutaka Inui
This paper describes the results of lube oil consumption test in order to ensure sufficient reliability of a diesel engine, employing a prototype engine of 200 mm-diameter cylinder. The authors have tried to use a high-precision laser displacement detector in detecting the change of the lube oil surface levels in order to obtain the lube oil consumption rate when the continuous operation of the diesel engine is being performed. It was confirmed that the measurement of the lube oil consumption rate of the engine by using a laser displacement detector is more effective than the conventional method of measuring the lube oil level by visual observation. And, this paper presents the achievements that have been obtained through the tests as above described.
