1.

Hull Inspection: This involves a comprehensive examination of the vessel's hull, including the
outer plating, internal structure, coatings, anodes, and corrosion-prone areas. It may include
thickness gauging, ultrasonic testing, and visual inspections.
TSI to estimate the required area of cleaning and specify under water areas and the proper way
of cleanings high pressure cleaning prices vary according to way of cleaning refer to dry/ tariff
sheet
2. Propeller and Shaft Survey: This survey focuses on the propeller, shaft, and associated
components. It includes an assessment of the propeller's condition, shaft alignment, bearing
clearances, and propeller shaft seals. Spare requisition for simplex seal (outer and inner seals) to
ordered soon as possiple
3. Machinery and Equipment Inspections: This entails inspecting and testing various machinery and
equipment on board, such as engines, generators, pumps, boilers, refrigeration systems, steering
gear, and electrical systems. The objective is to ensure they are in proper working condition and
comply with relevant regulations.
4. Safety Systems and Equipment Checks: This involves verifying the functionality and compliance of
safety systems and equipment, including fire detection and suppression systems, lifeboats, life
rafts, lifebuoys, navigation lights, and signaling devices.
5. Tank and Compartment Surveys: Tanks, compartments, and spaces (fuel, ballast, cargo, and void
spaces) should be inspected for structural integrity, corrosion, leaks, and cleanliness. Gauging,
ultrasonic testing, and visual inspections may be necessary.
6. Stability and Load Line Survey: This survey focuses on assessing the vessel's stability criteria,
including verification of load lines, intact and damaged stability calculations, and compliance with
relevant stability regulations.
7. Electrical and Automation Systems Inspection: This involves a detailed examination of the vessel's
electrical systems, including generators, distribution panels, motors, control systems, and
automation equipment. It may include checks for proper grounding, insulation resistance, and
functionality.
8. Navigational and Communication Equipment Assessment: This entails inspecting and testing the
vessel's navigational and communication equipment, such as radars, GPS systems, ECDIS, AIS, VHF
radios, and satellite communication systems.
9. Life-Saving Appliances Inspection: This includes a thorough examination of life-saving appliances,
such as lifeboats, rescue boats, life rafts, life jackets, immersion suits, and emergency evacuation
systems.
11. Documentation and Record Review: The dry dock administration may review various vessel
documents, including certificates, maintenance records, logbooks, and surveys, to ensure
compliance with regulations and the validity of existing certifications. Cargo System Inspection: If
applicable, inspect the cargo systems, including cargo holds, hatches, pipelines, valves, pumps,
and loading/unloading equipment. Check for any signs of damage, corrosion, leaks, or
malfunctions.
12. Anchor and Mooring Equipment: Inspect the anchor and mooring systems, including anchor
chains, windlasses, capstans, winches, and mooring lines. Ensure they are in good condition,
properly secured, and capable of performing their intended functions.
13. Ventilation and HVAC Systems: Assess the vessel's ventilation and HVAC (Heating, Ventilation,
and Air Conditioning) systems, including ducts, fans, filters, and air-handling units. Verify their
operational efficiency, cleanliness, and compliance with ventilation standards.
14. Pipework and Plumbing: Inspect the vessel's pipework and plumbing systems, including
freshwater, sewage, and ballast systems. Check for leaks, blockages, corrosion, and ensure proper
functioning of valves, pumps, and fittings.
15. Hull Cleaning and Maintenance: Coordinate hull cleaning, including the removal of marine
growth, fouling, and barnacles. Also, consider hull coating maintenance, such as touch-ups,
repairs, or full recoating, as necessary.
16. Rudder and Steering System: Inspect the rudder and steering system, including pintles, gudgeons,
bearings, hydraulic cylinders, and control mechanisms. Verify proper alignment, lubrication, and
operation.
17. Accommodation Areas: Evaluate the condition of accommodation areas, including cabins,
common spaces, galleys, and sanitary facilities. Ensure compliance with cleanliness, safety, and
hygiene standards.
18. Life Safety and Firefighting Systems: Inspect the vessel's fire detection and suppression systems,
including fire extinguishers, fire alarms, smoke detectors, and emergency lighting. Test the
functionality of emergency escape routes and signs.
19. Sea Chests and Valves: Check sea chests, sea valves, and associated piping for cleanliness, proper
operation, and any signs of blockage or corrosion. Ensure valves are properly exercised and in
good working condition.
20. Bilge and Ballast Systems: Assess bilge and ballast systems, including pumps, valves, strainers, and
alarms. Inspect for any leaks, blockages, or malfunctions that could affect water drainage or
stability.
