摘要

2010年10月13日San Diego停泊中の主機関 カム軸点検時、No．2及びNo．3シリンダの燃 料カム表面に爪で引っかかる程度の亀裂のよ うな線を確認した。%During inspection of the main engine camshaft while the ship was at the berth in San Diego on October 13, 2010, crew members confirmed that there were lines, like cracks, which just hindered the movement of a fingernail against them, on the surfaces of fuel cams of Nos.2 and 3 cylinders.
