Best Practices and Digital Tools for Dry

Proven strategies that help operators execute on-time, on-budget dry docking while maintaining quality standards and minimizing operational disruption.

Early Planning & Berth Reservation

Start 12 Months Early: Korean shipyards book up 6-12 months in advance. Late booking results in berth unavailability, premium pricing, or undesirable timing.

Planning Approach:

Identify 2-3 month window for dry dock 12 months out based on commercial schedule and survey due dates
Request quotations from 4-6 shortlisted yards - compare not just price but total value, reputation, technical capability
Secure berth with deposit (10-20% of estimated cost) to lock in pricing
Maintain backup yard as alternative if schedule changes required

Impact: Early planning secures preferred berth at competitive rates and provides adequate time for parts procurement, avoiding expensive rush orders.

Comprehensive Work Specification

Document Everything: Detailed work specification prevents misunderstandings, cost disputes, and rework. Acts as contract defining expectations.

Key Components:

Hull Work: Steel renewal locations with drawings, coating specifications (IMO PSPC if applicable), surface preparation degree
Machinery: All machinery items for overhaul with extent of work, spare parts to be used, performance testing requirements
Quality Standards: Reference applicable standards (IACS, ISO, IMO), NDT testing requirements, welding procedures
Schedule: Tentative work schedule by week, critical path items, milestone dates

Best Practice: Living document updated as additional work identified. Change order process defined upfront. All variations documented and approved before execution.

Proactive Parts Procurement

Parts Availability Critical: Missing spare parts cause $30K-50K per day delays. Proper planning avoids expensive rush air freight.

Procurement Timeline:

6 Months Before: Identify all required parts. Obtain quotations from suppliers
4-5 Months Before: Order long-lead items (major machinery components, propeller, specialized coatings). Lead time 12-20 weeks
2-3 Months Before: Order standard parts (seals, gaskets, bearings, filters). Lead time 4-8 weeks
1 Month Before: Confirm all deliveries. Track shipments. Expedite delayed items

Critical: Missing one $500 bearing can delay $1.2M dry dock. Detailed parts tracking essential - know what's ordered, where it is, when it arrives.

Common Questions

How far in advance should we book dry dock berth in South Korea?

Book 6-12 months in advance for major Korean shipyards. Busan/Ulsan yards: 3-6 months typically sufficient. Geoje yards (Samsung, DSME): 6-12 months required due to high demand. Booking late results in: (1) No berth availability forcing schedule compromise, (2) Premium pricing for short-notice bookings, (3) Compressed preparation time. If dry dock driven by survey due date, start planning immediately after previous dry dock completion.

What causes dry dock costs to exceed budget?

Primary overrun causes: (1) Steel renewals exceeding estimates (30-50% of overruns) - surveyors find additional corrosion during tank inspections. Average special survey discovers 50% more steel work than initially estimated. (2) Machinery issues (20-30%) - equipment internal condition requires overhaul despite acceptable external appearance. (3) Weather delays (10-20%) - rain delays coating work, each extra day costs $30K-50K. (4) Scope creep (10-15%) - adding nice-to-have items not in original scope. Mitigation: Budget 25-35% contingency, detailed pre-dry dock inspections, fixed-price contracts where possible, strict change order approval, real-time cost tracking.

How do we select the right shipyard in South Korea?

Selection criteria beyond price: (1) Technical capability - Can yard handle your vessel size and complexity? Experience with your vessel type? (2) Reputation - Ask other operators about their experience. Check on-time completion rate and quality. (3) Survey relationship - Is yard experienced with your class society? Good relationship smooths process. (4) Communication - English-speaking project managers essential for complex work. (5) Location logistics - Port access, crew change facilities, parts delivery infrastructure. Process: Request detailed quotations from 3-4 shortlisted yards. Ask for references from recent customers. Consider site visit before final selection. Sometimes mid-price yard with excellent reputation better than cheapest with unknown quality.
