For Chief Engineer and Second Engineer,

This post will cover preparations for drydocking until entering.
Shipyard departments: Carpentry, Electrical, Hull, Marine, Mechanical, Piping, Electrical, Steel, Support service

Preparations before Dry-docking

3-6 MONTHS PRIOR
1. Repair Specifications (AKA “Docking Specs” etc)
Intro: This is a collection of jobs to be done by the shipyard, and usually prepared by the Chief Engineer to submit to Tech Supt/Vessel Manager for approval. Split into “Electrical” and “Mechanical” categories and numbered for easy reference during meeting. The shipyard will assign to their various departments accordingly. Note: DOES NOT include ship crew’s jobs. Make a separate plan for ship crew’s jobs to submit to the Tech Supt/Vessel Manager for approval.

How to prepare:
– Survey jobs (check what’s due i.e. Annual, Intermediate, Special, CMS survey items)
– Routine dry dock jobs (e.g. Large electrical motors for overhaul)
– Jobs not part of survey scope but crew is not able to carry out (e.g. Retrofit BWTS, corroded superstructure needing major cutting and welding)
– Check vessel’s or sister vessel’s past Repair Specs for reference (if available)

2. Reference materials to prepare:
A) Docking plan

* Especially important as Sea Chests, Echo Sounder and Speed Log Transducer will be cleaned/checked. CE and 2E must be familiar with all overboard discharge marks. Names and locations as given below:

B) Both E/R and Hull piping drawings
Especially important for checking specs for replacement of pipe spools, valves, etc.

C) Construction drawings (Structural steel renewal)

D) ALL machinery manuals
* Would be helpful to have a spreadsheet of all the machineries, maker, model, WEIGHT for easy reference by repair team!

E) Previous class survey reports (as applicable)

F) Previous clearance and measurements (especially major components such as stern tube wear down, main engine bearings clearance measurements etc)

G) All tanks, cofferdams and their capacities
Useful for planning tank cleaning (manpower, materials, manhours).
Various references available for this, such as Capacity Table (or “tank calibration” book)

Or Capacity Plan

3. Spare parts and special tools
A) Double check spare parts and special tools ROB (especially on old vessels or second-hand vessels where important special tools like wear down gauge might be missing)
B) Check the fleet management system for any expected deliveries before entering dock
– Don’t make double orders unknowingly, it’s troublesome to cancel and costly if delivered.
– Consider consumption and extra quantity in case of damage by human error during dry docking

4. Shore connection
– Check condition of Shore Power connection bus bar for rust, wear etc. especially for older vessels. Repair/order spares as necessary.

1-2 MONTHS PRIOR

1. Plan minimum bunkers (F.O, M.G.O, L.O, F.W) and ballast carried
A) Plan minimal safe top-up of M/E and A/E L.O to facilitate less wastage when engine overhaul carried out and crankcases are cleaned
B) Cross-reference with class survey status report + voyage plan to plan how much minimal amount to top up in each tank, to help facilitate transfers and tank cleaning in drydock (especially for F.O tanks, it’s a hassle)
2. Draw up list of items to offload for overhaul/repair (e.g. large electrical motors)
3. Plan and carry out hold/tank cleaning/gas freeing before arrival
4. Pump engine room bilge wells to minimum suction, and clean engine room tank top and bilges
5. Run O.W.S. to reduce bilge holding tank to minimum level to facilitate cleaning in drydock. Monitor working performance and report if unsatisfactory especially if old design, as rectification can be done easier during drydock.
6. Flush bilge lines thoroughly after O.W.S operation. Clean O.W.S and renew components (e.g. coalescers) as necessary, especially when expecting IOPP survey during drydock
7. Mark out all valves and sea chests strainers to be cleaned/overhauled
8. Measure dimensions of flanges for yard to connect cooling S.W. line (e.g. for A/C and refrigeration), and prepare blanks if necessary
9. Test Emergency Generator on load
10. Secure heavy loads
11. Prepare firefighting plans, safety measures, equipment and brief the crew
10. As appropriate, reduce sludge tanks ROB according to company’s instructions (e.g. shore disposal or incineration) and prepare them for cleaning

1 WEEK PRIOR
1. Take and record soundings of all tanks and cofferdam
2. Flush sewage treatment tanks and sewage treatment plant thoroughly, for easy shut down, cleaning and close inspection in drydock. Sewage and grey water will be disposed by yard during drydock.
3. Plan M/E, A/E and boiler changeover to D.O/M.G.O with adequate time
4. Same time plan for F.O and L.O purifiers to stop at the right time
5. Secure CO2 systems with lockout before entry into dock
