Sampling frequency
Bast oil samples are collected at quarterly intervals (sent every January/April/July/October where practicable) and sent for laboratory analysis in accordance with normal equipment operation.
If the initial oil analysis report is unsatisfactory or is deemed necessary for further analysis, subsequent samples must be taken and submitted for testing to confirm the analysis results.
Additional testing of the stern tube system for water should be carried out if the SENIOR MECHANIC suspects water contamination in the stern tube system.
If the test report states that the equipment is deficient and corrective action has been taken, then an oil sample should be taken 1 month after corrective action has been taken, or sooner if deemed necessary, and sent for analysis at the next convenient port. The vacancy of a senior mechanic requires attention and knowledge to manage the entire machine team.
Analytical report
The Lub oil test report must be submitted promptly to the ship's Master/Chief Engineer without undue delay. The Chief Mechanic, upon receipt of the test report, shall immediately take the corrective measures recommended in the test report and closely monitor the operational condition of the equipment.
The Chief Engineer shall record any corrective action taken in the ship's monthly maintenance reports for submission to the Ship's Management Office. All test reports must be submitted in due order for inspection or review if deemed necessary.
The vessel must report to management when a specimen lands on shore. The Superintendent must make arrangements with the agent to ensure that the sample is actually delivered and sent to the testing laboratory.
The purifier must operate at minimum performance and at a specified temperature. The correct gravity disc should also be used. The main engine lubricating oil must be continuously centrifuged, and when circumstances permit, the engine lubricating oil will be poured into the repair tank if it is full to heat, settle and then return to the crank housing through the centrifuge.
Electrical installation (senior mechanic vacancies)
The number of alternators on load, whether at sea or in port, depends on the operational and internal requirements of the ship and must always be sufficient to ensure safe continuity of supply. Idle main and emergency diesel generators should be checked weekly and, if installed, remote and automatic controls checked.
When the ship is navigating in narrow waters, entering and leaving port, etc., a standby alternator should be in use and share the load at the main distribution board. The ship's shaft alternators, if installed, should not be used for electrical or domestic loads when the ship is sailing in pilotage waters or during river passages (chief engineer vacancies).
Support mechanisms
In all cases where redundant units are installed, the operating time should be evenly distributed between the two units. All automatic switching devices must be checked when the units are put into operation and when they are stopped. Disconnections should be checked at regular intervals.
Boiler equipment
Adjustment of safety valves: It is necessary that after each inspection the safety valves are adjusted to the correct safe operating pressure.
This adjustment must be made to the satisfaction of the surveyor the first time steam is raised on the boiler. In cases where the combustion devices are designed in such a way that the normal operating pressure of the boiler cannot be achieved until the vessel is put into operation,
Safety valves must be adjusted by a senior mechanic to the correct safe operating pressure. This must be recorded in the ship's log and communicated to the classification society and company by telex. The logbook entry must be presented to the next class inspector present for verification and completion of the societies' records.
Emergency Steering Gear (notice of vacancy for senior mechanic)
The emergency steering gear must be checked at least once every three months. An appropriate entry must be made in the engine room test log and in the Official OLS Log (Ship's Log) or Deck Log.
Emergency steering operating instructions must be posted on the website. More detailed information about the SOLAS steering gear test rules can be found in the SOLAS V-Shipping Safety chapter. These rules must be strictly followed and considered as a minimum requirement.
US CFR requires additional testing before entering US waters beyond SOLAS requirements.
Once the opening pressure is set and approved by class society, the pressure adjustment mechanism of the safety valve must be locked and no one must interfere with it. For emergency situations when the boiler requires ventilation, the safety valves should only be activated remotely.
