Categories of repairs and maintenance
Basically, repair work can be classified as follows:
Regular scheduled maintenance
Items that can be classified under this include:
Preventive Maintenance - This category requires items to be opened for inspection and major repairs at specified intervals or after a specified number of hours of operation. Maintenance is carried out regardless of the condition of the machine to keep the machine in satisfactory operating condition.
Applicants for second mechanic positions should be aware that periodic inspection of required items and certain machinery is in accordance with the established schedules of the classification societies listed in their annual and quarterly inspection status.
Inspection/maintenance of safety equipment items in accordance with the requirements of flag states, regulatory and classification authorities, namely: annual maintenance of life rafts, pressure testing of portable fire extinguishers, etc.
Unscheduled maintenance
This applies to internal and external decks, superstructures and bulkheads, mast and rigging, deck hardware and mooring fittings, piping and valves and other miscellaneous fittings.
For these items, the decision of the chief mate or chief engineer is based on the development of a repair and maintenance plan, taking into account differences in the vessel's age, design and maintenance requirements.
Conditions and trading patterns may lead to
Condition-based maintenance can also fall into this category. This is dictated by the operating characteristics or physical condition of the machine, as determined by regular or continuous testing of applicable parameters, and is performed only when operating conditions deteriorate below a satisfactory standard, but before breakdown or failure occurs.
Repair
This can be divided into:
Damage repair – which may consist of:
Collision damage.
The stevedore damaged the vessel and its equipment as a result of mishandling and negligence.
Corrective repair work is sometimes called breakdown maintenance and is performed only to restore a machine or component to operating condition after a failure or malfunction due to normal wear and tear.
Periodic and emergency repairs - This includes items such as routine docking, as well as all repairs and maintenance not available to ship personnel.
Warranty Repairs - This usually applies to boats that have been recently taken from the yard and this period usually lasts twelve months from the date of delivery.
From the date of delivery, all faults arising due to faulty housing design, construction, mechanisms, etc., incorrect installation or damages arising due to faulty design, etc., until the expiration of the warranty period, the developer will accept them at his own expense.
Warranty repairs may also be the repair of newly installed equipment on board an existing vessel in the event of any failure due to a fault caused by manufacture during the stated warranty period.
Responsibilities and order
Both the chief engineer and chief engineer, as well as the senior director, are key personnel on board who are responsible for the development, efficiency, planning and distribution of maintenance work in accordance with departmental requirements.
The foreman, together with department heads, should meet regularly as necessary to develop a maintenance program, coordinate the activities of various departments, establish areas of responsibility and develop a sequence of actions. In their meetings, they should also identify potential hazardous areas on the ship that could compromise the safety of the ship and personnel and develop ways to take corrective action as a priority.
Before undertaking routine major repairs and maintenance of machinery or equipment on ships, which involves shutting them down, permission must be obtained from the master, who will then consider whether the safety of the ship will be affected during immobilization or whether the ship's charter requirement will be met . will be difficult.
A progress report must be submitted to the office on a monthly basis.
In the event of any maintenance or repair of an important or critical nature, which may include the disabling of essential equipment that affects maneuverability, seaworthiness or prevents the vessel from performing its essential operational tasks, the office must be immediately informed to take necessary action.
