WHAT DOES THE OSM THOME DRY DOCKING SUPERVISION INCLUDE?

Ship maintenance during a “dry docking” period encompasses a wide range of activities aimed at keeping a vessel in good working condition, ensuring its continued compliance with regulatory requirements, and when required, extending its operational lifespan.

The specific tasks can vary depending on the type of ship, its age, its operational profile, and regulatory requirements, but here are some common elements of a typical vessel’s docking maintenance activities.

 

1. Hull Maintenance:

    • Cleaning and painting the ship’s hull to remove biofouling and ensure corrosion prevention.
    • Inspecting and repairing any damage to the hull, such as cracks, dents, or structural damages.
    • Servicing of impressed current corrosion prevention system (if fitted) or renewals of sacrificial anodes.
    • Measurement of the tail shaft and rudder clearances. Replacement of tail shaft seals as required.
    • If the vessel has thrusters or a CPP, then their maintenance as per the maker’s recommended periodic servicing should be carried out.

2. Machinery and Systems Maintenance:

    • Regular servicing and overhauling of engines, generators, and auxiliary machineries; including their control and automation system, to ensure they operate efficiently and safely. Makers will be engaged to ensure that any required software updates are implemented.
    • Cleaning and inspecting auxiliary systems. Replacement of any leaking pipes, pumps and clearing of pipe and filter blockages that will impede the flow rates and affect correct operations in service.

3. Electrical Systems Maintenance:

    • Checking, maintaining and recalibration of electrical systems, including circuit breakers, wiring, switches, and control panels.
    • Replacing or repairing damaged or malfunctioning electrical components.

4. Navigation, Cargo loading and monitoring and Communication Equipment Maintenance:

    • Testing, software updates and calibrating of navigation instruments, such as GPS, LRITs, AIS, radar, gyrocompasses and echo sounders, amongst other navigational aids.
    • Ensuring the functionality of communication equipment like GMDSS radios, EPIRBs, SARTs and satellite communication systems.
    • Cargo loading software and monitoring systems to be checked by the maker for any updates or upgrades required.

5. Safety Equipment Maintenance:

    • Inspecting and servicing lifeboats, liferafts and their launching arrangements; immersion suits, life jackets, fire extinguishers, and other safety equipment that may be cargo-specific requirements.
    • Testing of fire detection and fixed suppression systems.

6. Deck and Superstructure Maintenance:

    • Cleaning, descaling and painting the ship’s deck and superstructure to prevent corrosion.
    • Replacing or repairing damaged deck components, such as railings; pipes and valves; cable trays, lighting and monitoring arrangement; windlass, winches and their associated mooring fixtures; or Cargo and/or provision cranes.
    • Periodic pressure testing of pipes on deck.
    • Periodic brake holding test for winches and windlass.
    • Periodic load testing of cranes.

7. Interior Maintenance:

    • Keeping the living quarters, sanitation and heating, ventilation, and air conditioning (HVAC) systems, and common areas clean and repairs or replacements will be executed to maintain compliance with safety and MLC requirements.
    • Repairing or refurbishing interior fixtures and furnishings that have excessive wear and tear from daily use.

8. Safety Inspections and Surveys:

    • Compliance with regulatory inspections and surveys by classification societies and flag state authorities.

9. Environmental Compliance:

    • Managing waste disposal and pollution prevention, and disposal of hazardous materials in accordance with environmental regulations.
    • May require the retrofit of systems for compliance with current regulatory requirements. Examples, Ballast Water Treatment systems and exhaust gas scrubber systems. Fuel Oil sampling points.

10. Crew Training (this will usually be done by visiting safety Coaches or by VMs):

    • Observation of crew in their execution of safety and operational activities; and implementing immediate corrective changes/training if any lapses are observed.
    • Briefing and training the crew on any updates in the company ISM/ISPS/MLC processes.
    • Briefing and training the crew with any environmental and regulatory updates.

11. Record-Keeping:

    • We will provide a daily work progress update.
    • Any work variation or additional work scope will be discussed with the Owner for acceptance, as these will typically have an impact on the budget prepared.
    • Liaison with yard for the compilation of a detailed docking report with records of maintenance, calibrations and repairs carried out.

Proper ship maintenance is crucial for the safety of the crew, the protection of the environment, and the longevity of the vessel. It also helps prevent costly breakdowns and ensures the ship’s continued ability to perform its intended functions.
