Stern tubes
On boats equipped with water-cooled, oil-lubricated stern tubes, there should always be enough water in the bottom after peak (or in the stern tube cooling tank) to cover the stern tube before using the main engine.
Indicator cards and condition monitoring
Indicator charts from the main engine, where applicable, shall be taken in accordance with equipment operation report instructions or as required by the supervisor
A second mechanic vacancies to ensure that the timing and combustion conditions are correct. This information should be sent to the company in a monthly status report.
Ideally this should be done while the ship is on a straight course with no expected course changes. Sea conditions are preferably calm, with minimal wind and current forces. The vessel should be fully loaded with as little trim as possible.
Main engine vessels equipped with the means to obtain data for manufacturers' performance programs, second engineer vacancies, must forward relevant data to the company in a monthly status report. This data should be transmitted more frequently to suggest that poor or reduced performance is suspected.
if the Second Engineer is vacancy and has Vibration Monitoring. Portable vibration monitoring equipment is provided on specific vessels to evaluate the operation of rotating mechanisms. The manufacturer's instructions supplied with the equipment must be followed. Concept
The use of this equipment is to identify trends. Therefore, accurate record keeping and analysis of previous readings is essential to identify changes in vibration levels present in equipment. This way, costly breakdowns can be avoided. Conversely, scheduled maintenance may be delayed if the readings obtained remain at a constant level. Where not provided by the company, the chief mechanic should list all major rotating and reciprocating machines for monitoring. Three positions on each piece of equipment must be selected and marked with paint. Tests are carried out on the bilge/suction line When testing the bilge and suction lines, there is a possibility of water entering the engine room. To avoid this possibility, the following practice should be followed when performing these tests (second mechanic vacancy). Testing of suction devices should be carried out using practical pumping tests. Tests for valve tightness should be carried out by increasing the pressure in the line. Conversely, instead of a pressure test, the condition of the valves can be checked, but the tightness of the valves must be checked. The bilge and ballast suction lines must not be subjected to pressure exceeding 3 bar during testing. The tests carried out must be recorded in the deck logbook. All isolation and shut-off valves between ballast pumping systems and bilge/bilge suctions should be closed and the pressure in the bilge suction pipes should be controlled to avoid overpressure in the mains. After the ballast and bilges have been pumped out, secured and insulated, the individual systems must be checked. The practice of simply closing a series of valves should be avoided to save time during future pumping (second mechanic vacancy). minimum During the voyage, the holds should be sounded daily. the results should be kept in the deck logbook.
