Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

Abstract: The present invention relates to a method for acquiring location information of an observation buoy reflecting influence of an ocean current and a method for assessing damage risk relating to spilled oil dispersion of a sunken ship by using same location information. At least one small observation buoy is floated on a target sea area, and a relay buoy collects location information from the observation buoy and predicts ocean current distribution of the target sea area on the basis of the collected information; and the predicted ocean current distribution is applied to a step of predicting spilled oil dispersion in a surrounding sea area so that damage risk relating to spilled oil dispersion of a sunken ship is precisely assessable.
