Inspections/full package, Frosio-Nace certified Inspectors

D*C*C* is also pleased to present our thoughts/suggestions regarding a continuing long term planning, program/service regards to:

• surface treatment during dry dockings

• overall status reports

• inspectors during dry dockings

• onboard maintenance courses for vessel crew

• ballast tank inspection courses for involved officers onboard

• technical advices regards to paint specifications, job specifications, yard quotations etc.

This can be carried out on day by day basis (daily rates) or as a full package with a price pr. Vessel pr. year or a price for the entire fleet pr. year.

Background: As most of cargo’s today (pricing/quality) is decided due to the conditions of class for the vessels (Cap. 1, 2, 3), it is important to maintain/upgrade the vessels overall conditions, in order to achieve/maintain predefined class rating. When this is said “not to waste unnecessary finances,” upgrading areas not needed in order to achieve the class ratings, but not to be forgotten in the long term planning as well. As the background and skills vary amongst Superintendents and the Officers onboard, it can in most cases be difficult to ensure that the surface treatment/maintenance is uniform and optimized across the entire fleet.

D*C*C* suggestions/solutions D*C*C* can/will enter into a long term arrangement with ship owners regarding ballast tanks, coated cargo tanks, hull, deck, superstructure etc. all areas coated.

This includes:

• In cooperation with owner’s Superintendents, creating an overall plan for the vessels based on status reports and dry docking schedules

• Carry out inspections, in order to get a full status report of all the vessels

• Inspection of the vessels 12+/- month prior dry docking proposals for action needed incl. paint/job specifications etc

• Provide companies with paint inspectors during entire dry dockings

• Technical service/advice from office in Poland

• Frequently meetings, D*C*C* project manager updating/status for owners Superintendents

• We envision Frosio or Nace certified Coating Inspectors

• Scope:

• To evaluate the overall paint condition in ballast tanks: forepeak, Db. 1Ps & Sb. Db. 2 . Db. 3 Ps & Sb. Db. 4. Db.5 Ps & Sb. Db. 6. Db. 7 Ps & Sb. Db. 8. Db. 9 Ps & Sb. Aft. Peak tank.

• Make proposal for paint/repair specification and suggest remedial action needed in order to bring the protection of the areas up to predefined standard, in this case CAP 2.

• Ratings: Tanks has been inspected and rated according to IACS criteria’s an requirements

• GOOD, FAIR, POOR

• GOOD: condition with only minor spot rusting. GOOD: Condition with spot rusting on less than 3% of the area under consideration without visible failure of the coating. Rusting at edges or welds, must be on less than 20 % of edges or weld lines in the area under consideration

• FAIR: condition with local breakdown of coating at edges of stiffeners and weld connections and/or light rusting over 20% or more of areas under consideration, but less than as defined for POOR condition. FAIR: Condition with breakdown of coating or rust penetration on less than 20 % of the area under consideration. Hard rust scale rust penetration must be less than 10 % of the area under consideration. Rusting at edges or welds must be on less than 50 % of edges or weld lines in the area under consideration.

• POOR: condition with general breakdown of coating over 20% or more of areas or hard scale at 10% or more of areas under consideration. POOR: Condition with breakdown of coating or rust penetration on more than 20% or hard rust scale on more than 10% of the area under consideration or local breakdown concentrated at edges or welds on more than 50 % of edges or weld lines in the area under consideration.

• IACS clarification of “GOOD”, “FAIR” and “POOR” coating conditions

GOOD FAIR POOR

Breakdown of coating or area rusted (1) < 3%

3 – 20 % > 20 %

Area of hard rust scale (1)

- < 10 % ≥ 10 %

Local breakdown of coating or rust on edges or weld lines (2) < 20

% 20 – 50

% > 50 %

Notes (1) % is the percentage of the area under consideration or of the “critical structural area” (2) % is the percentage of edges or weld lines in the area under consideration or of the “critical structural area” (3) spot rusting i.e. rusting in spot without visible failure of coating

Observations and assessments in ballast tanks:

The existing coating system assessed is a Zinc epoxy shop primer followed by two coats of coal tar epoxy averaging from 400 to 800 microns.

Conclusion:

Apart from aft. Peak tank, which is in good condition, all tanks are in fair condition when blistering, corrosion and delaminating taken into consideration.

The blistering followed by corrosion appears mainly due to two reasons. Zinc salts from the Zinc shop primer, when wet, the Zinc salts are extracted from the shop primer and creates blistering. Also the pattern of the blistering indicates a lack of ventilation when the following coats were applied during new building stage.

Recommended action:

To limit further blistering and corrosion in near future, and to achieve cap 2 rating, we recommend to repair the affected areas by means of sand washing and recoating. This surface treatment appears to be the best solution regards to the economic aspect holding it up against fully blasting within the next few years time. The price for sand wash and coatings is approx. Half the price holding it up against a full blast/coating.

This could be carried out as a voyage repair in order to save off hire costs but also in order to save money on the actual m2 price when quoted for by ship yards that has a tendency of quoting too high prices due to inexperience regards to sand-washing. If voyage pattern allows a team of two men could bring all tanks up in cap 2 rating within a couple of seasons when supervised and instructed properly.

Job-specification

Ballast tanks.

1. H.P. fresh water wash all areas for repairs

2. Sand wash all blistered and corroded areas, with pressure of 160-350 bar.

4. Flush all areas for repair by means of hosing down the tank with freshwater. All areas for coating to be 100% clean prior coating.

5. Dry the tanks by means of good ventilation.

6. Apply full coat of mastic alu, to a min. Dft. Of 200 mic.

7. Apply stripe coat of mastic to all weld seams, scallops and hard to reach places in affected areas.

8. Apply full coat of mastic dark coloured to a min. Dft. Of 200 mic.
