Dry Dock
Preparing a docking means connecting due dates, ship condition and work with surveys, checks and redelivery. This module explains those connections, distinguishing planning, technical evidence and documents.
To define the project, consult planning, contracts and sister ships. To understand the survey due and items to prepare, consult the bottom/IWS, dry-dock survey, ESP cargo-hold and component topics; UTM and RIT explain different forms of evidence. Coating, waste and hot work connect specifications, checks and responsibilities. Warranties explain follow-up of defects found after repair.
The IHM concerns hazardous materials and inventory updates; PSPC and AFS address coatings within different scopes. Each topic provides explanations, references, examples, mistakes, checklists and FAQ. Choose a topic from the actual question: the catalogue order does not prescribe a work sequence.
Dry Dock Entry Planning
Dry-dock planning starts from statutory and class due dates, ship condition and yard capability; timing, scope and contingencies must be built for the specific project.
Bottom Survey and In-Water Survey (IWS)
The bottom survey must make the hull and related items verifiable. In dry dock or afloat, preparation, evidence quality and the applicable regime determine what can be examined and credited.
Survey in Dry Dock
A dry-dock survey connects items to examine, preparation, evidence and acceptance. Classification and statutory certification have their own scopes and authorities; follow-up remains open until findings, repairs and documents are reconciled.
Coating and PSPC (Performance Standard for Protective Coatings)
Steel protection depends on coating preparation, compatibility, application and checks. In dry dock, observed condition and specification guide the repair; the CTF and records make the work verifiable.
Thickness Measurement (Ultrasonic Thickness Measurement, UTM)
A UTM reading is useful when it measures the material with a suitable method and remains linked to location, reference and conditions. The report supports hull assessment; the displayed number does not itself decide acceptance.
Tail Shaft Survey
A tail-shaft survey examines the propeller shaft, bearings, seals and propeller as an assembly. Understanding the installed arrangement helps prepare relevant evidence, distinguish monitoring from survey and follow defects through to an outcome accepted by class.
Rudder and Sea Chests (Sea Chests and Sea Valves)
The rudder steers the vessel; sea chests and valves connect the hull to seawater systems. A dock survey makes the condition, clearances and tightness of these components assessable, linking each finding with the required checks and restoration.
Anchor and Chain Cable Survey
An anchor and chain cable survey connects equipment examination, wear measurements and component identity with service condition. The survey helps identify defects, support renewal decisions and make the equipment returned on board verifiable.
Cargo Hold Survey for Bulk Carriers (ESP)
Cargo-hold surveys connect structural examination, access and thickness measurements to the ESP programme. Findings and ship history guide further investigation; reports, repairs and outcomes must remain traceable to the areas examined.
Shipyard Waste Management during Dry Dock
Waste management in dry dock links each job to an identified stream, collected separately and followed through to its documented destination. Ship and yard agree responsibilities, containment and delivery evidence before work starts.
Managing Shipyard Repair Contracts
Specification, bid and contract define the shipyard work. During execution, variations, tests and outstanding work must remain linked to authorised decisions and the agreed redelivery.
Managing Post-Repair Warranties (Warranty Claims)
Managing a post-repair defect means documenting facts, checking notice terms and receipt, preserving evidence and following the remedy. The claim outcome and the ship’s safe restoration require distinct evidence.
Dry Dock Scheduling for Sister Ships (Sister Ship Scheduling)
Experience from the first ship helps prepare sister ships’ dockings when it leads to targeted verification on each vessel. Differences, inspection outcomes and individual due dates guide work, quantities and docking sequence.
Hong Kong Convention: Inventory of Hazardous Materials and Green Passport
The IHM links hazardous materials to their locations and quantities on the individual ship. Part I is maintained during the operational life; Parts II and III are prepared before recycling. In dry dock, the inventory is checked against removals and new installations.
Next-Generation Coating: Planning the Dry Dock Choice
Select the external anti-fouling system against AFS compliance, operating profile and planned maintenance. Advertised coating life does not change bottom-survey and docking due dates.
Hot Work Permit at the Shipyard: Ship-Dock Coordination
The hot-work permit must coordinate ship and yard: permission to enter a space does not mean welding or cutting is permitted inside it.
Remote Inspection Techniques (RIT): Drone and ROV Inspections
RIT brings images and, where included, measurements to the surveyor from hard-to-reach parts of the structure. Understanding whether the result is usable means linking the activity, system capability, position and coverage to the required examination and its acceptance.
