To provide a laser-type gas analysis system for ships which can predict the correctness of a concentration indication value of a measurement target gas during an operation and can make a flexible response to a correction operation.SOLUTION: The present invention relates to a gas analysis system (1) for analysing a measurement target gas in a discharged gas of a ship, and the system includes: a laser-type gas analysis meter (2); a discharged gas purifying device control disc (3) for controlling the discharged gas purifying device and collecting data; and data analysis units (4, 5) for analyzing the data. The data analysis unit measures the degree of separation between the concentration indication value as correction information and the engine output value by using the correlation between the concentration instruction value and the engine output value acquired by the discharged gas purifying device control disc.SELECTED DRAWING: Figure 1 【課題】運用中における測定対象ガスの濃度指示値の正しさを予測でき、校正作業に柔軟に対応できる船舶用レーザ式ガス分析システムを提供することを目的とする。【解決手段】本発明は、船舶の排ガス中に存在する測定対象ガスのガス分析を行うガス分析システム（１）であって、レーザ式ガス分析計（２）と、排ガス浄化装置の制御とデータの収集を行う排ガス浄化装置制御盤（３）と、前記データを解析するデータ解析部（４，５）と、を具備し、前記データ解析部は、前記濃度指示値と前記排ガス浄化装置制御盤にて取得したエンジン出力値との相関性を利用して、校正情報としての前記濃度指示値と前記エンジン出力値との乖離度合いを計測する、ことを特徴とする。【選択図】図１
