- The major, planned maintenance period where a vessel is brought to a shipyard and removed from the water for hull inspection, repair, and major machinery overhaul, typically every 5 years.
- Five-Year Special Survey Planning: Developing a comprehensive scope of work that aligns with the vessel's special survey cycle and Class requirements.
- Dry Dock Yard Selection and Negotiation: Vetting shipyards globally based on competence, availability, and negotiating the most competitive dry dock contract terms and pricing.
- Scope and Specification Development: Creating highly detailed specifications for all hull, machinery, and electrical works, including necessary retrofits (e.g., scrubber, BWTS).
- Critical Path Scheduling: Developing a precise project schedule that identifies the critical path and minimizes the total duration the vessel is out of service.
- Mobilization and Demobilization: Managing the safe and efficient transfer of crew, spare parts, and specialized contractors to and from the shipyard.
- On-Site Project Management: Assigning a dedicated, experienced superintendent team to provide continuous oversight and quality control during the dock period.
- Budget Control and Variation Order Management: Implementing a strict budget monitoring system and tightly controlling costs resulting from unforeseen repair work (variation orders).
- Hull Preservation and Coating: Specifying and supervising the application of high-performance anti-fouling and anti-corrosion coatings to maximize efficiency and longevity.
- Propeller and Rudder Inspection: Conducting mandatory inspections and necessary repairs/polishing of the propeller and rudder systems to ensure hydro-dynamic efficiency.
- Machinery Overhaul Coordination: Scheduling and managing the overhaul of main engines, auxiliary engines, and other critical pumps and compressors.
- Safety and Quality Supervision: Enforcing stringent safety protocols and quality control checks for all contractor work within the confined and high-risk shipyard environment.
- Sea Trial and Post-Dock Performance: Conducting necessary post-dock sea trials to verify all repaired and newly installed equipment performs to specification.
- Final Class and Statutory Sign-Off: Securing the necessary final sign-offs and renewed certificates from the Class surveyor to return the vessel to service.
