1Which international standard sets mandatory requirements for protective coatings in dedicated seawater ballast tanks of new ships?

A.IMO PSPC (MSC.215(82))

B.NACE SP0108

C.SSPC-PA 1

D.ISO 12944-5

Explanation: IMO Resolution MSC.215(82) — the Performance Standard for Protective Coatings (PSPC) — sets mandatory requirements for dedicated seawater ballast tanks of all ships of not less than 500 GT and double-side skin spaces of bulk carriers ≥150 m, and became mandatory on 1 July 2008.

2What is the minimum nominal dry film thickness (NDFT) required by IMO PSPC for coating of dedicated seawater ballast tanks?

A.320 micrometres (µm)

B.125 micrometres (µm)

C.200 micrometres (µm)

D.500 micrometres (µm)

Explanation: IMO PSPC specifies an NDFT of 320 µm for ballast tank coating systems, achieved through a minimum of two spray-applied stripe coats and two spray-applied full coats, with light-coloured topcoats.

3Under the IMO PSPC 90/10 rule for ballast tank coating thickness measurements, which statement is correct?

A.90% of readings must be ≥ NDFT and the remaining 10% must be ≥ 0.9 × NDFT

B.90% of readings must be ≤ NDFT and 10% must exceed it

C.100% of readings must be ≥ NDFT with no exceptions

D.90% of readings can be any value if average ≥ NDFT

Explanation: The 90/10 rule states that 90% of all DFT readings must be greater than or equal to NDFT (320 µm), and none of the remaining 10% may fall below 0.9 × NDFT (288 µm). The maximum DFT is governed by the coating manufacturer’s maximum specified DFT.

4Which ISO 8501-1 surface preparation grade does IMO PSPC require for ballast tank steel after primary blasting?

A.Sa 2½

B.Sa 1

C.Sa 2

D.St 3

Explanation: IMO PSPC requires Sa 2½ (very thorough blast-cleaning) per ISO 8501-1 for ballast tank steel — both for the steel surface and for damaged areas of shop primer and welds during secondary surface preparation.

5What surface profile range does IMO PSPC specify for ballast tank steel after abrasive blasting?

A.30 to 75 micrometres (µm)

B.10 to 25 µm

C.100 to 150 µm

D.200 to 300 µm

Explanation: PSPC specifies a surface profile of 30–75 µm for ballast tank steel, measured per ISO 8503. Below 30 µm gives insufficient mechanical key; above 75 µm risks rogue peaks protruding through the coating.

6Which standard governs the assessment of dust quantity and size class on surfaces prepared for painting?

A.ISO 8502-3

B.ISO 8502-4

C.ISO 8502-6 (Bresle method)

D.ISO 8503-2

Explanation: ISO 8502-3 specifies the pressure-sensitive tape method for assessing dust on prepared steel surfaces. PSPC requires dust quantity rating ≤1 for dust size classes 3, 4, and 5.

7Per ISO 8502-4, what is the recommended minimum margin between steel surface temperature and dew point before coating application?

A.3 °C (5 °F) above the dew point

B.Equal to the dew point

C.1 °C below the dew point

D.10 °C below the air temperature

Explanation: ISO 8502-4 and most marine coating manufacturers require the steel surface to be at least 3 °C (5 °F) above the calculated dew point to prevent invisible condensation that would cause flash rust and impair adhesion.

8The Bresle patch test (ISO 8502-6) on marine steel measures which contaminant?

A.Surface-soluble salts (chlorides, sulfates)

B.Dust

C.Oil and grease

D.Mill scale

Explanation: The Bresle method uses an adhesive patch and a small water volume to extract surface-soluble salts (primarily chlorides) from the prepared steel, measured by conductivity and converted to mg/m² — critical for ballast tanks because residual salts drive osmotic blistering.

9What is the maximum residual soluble salt level (as NaCl equivalent) recommended by IMO PSPC for ballast tank steel?

A.≤ 50 mg/m²

B.≤ 200 mg/m²

C.≤ 5 mg/m²

D.No specific limit, manufacturer’s discretion

Explanation: IMO PSPC specifies a maximum residual salt content (as NaCl equivalent) of 50 mg/m² before primer application. Higher salt levels promote osmotic blistering once the tank is in service.

10Which secondary surface preparation requirement does IMO PSPC impose on weld seams, edges, and surface contaminants?

A.Sharp edges rounded to a minimum 2 mm radius (or 3-pass grinding), weld spatter removed

B.Edges may remain sharp if coating DFT is doubled

C.Welds need only be wire-brushed

D.Only the first 100 mm from edges needs treatment

Explanation: PSPC Table 1 requires edges treated to a rounded radius of at least 2 mm (or equivalent 3-pass grinding), weld spatter removed, sharp burrs ground, and surface contaminants removed. This is essential for the coating to achieve adequate film build over edges (edge retention).

About the AMPP Marine Coatings Exam

The AMPP Marine Coatings Inspector Specialty (Marine Coating Inspection Specialty) is a specialty endorsement on top of an active AMPP Coating Inspector Program (CIP Level 1, 2, or 3) credential. It validates the inspector's ability to apply IMO PSPC (MSC.215(82)) requirements for dedicated seawater ballast tanks, inspect newbuild and drydock work on ships and offshore structures, and assess marine-specific coating systems — hull anticorrosives, tiecoats, self-polishing copolymer (SPC) antifoulings, foul-release silicones, boot-topping, deck topsides, tank linings on chemical and crude tankers (PSPC-COT, MSC.288(87)), and cathodic protection on submerged steel. Candidates complete a 4-day Marine Coating Technology course (in-person or online) followed by an online-proctored theory exam delivered via Meazure Learning / ProctorU.

AMPP Marine Coatings Study Tips from Top Performers

1Memorise the IMO PSPC 'big six' for ballast tanks: 320 µm NDFT, 90/10 rule, Sa 2½ to ISO 8501-1, profile 30-75 µm per ISO 8503, soluble salts ≤50 mg/m², and two stripe coats plus two full spray coats — these recur throughout the exam

2Understand the difference between SPC antifoulings (biocide released via hydrolysing copolymer) and foul-release silicones (no biocide, low surface energy; needs vessel speed >12-15 knots to shed fouling) — distractor pairs lean heavily on this

3Drill the ISO 8501 family: 8501-1 Sa/St grades for uncoated steel, 8501-2 P Sa/P St for previously coated maintenance work, 8501-3 welds and edges, 8501-4 hydro-jetting flash-rust (FR L/M/H) and SSPC-SP WJ levels

4Know the ambient triad: steel ≥3 °C (5 °F) above dew point (ISO 8502-4), RH ≤85% per PSPC, surface temperature checked with a contact thermometer — and recognise when stop-work is required

5Practise cathodic protection numbers: protective criterion more negative than −0.80 V vs Ag/AgCl seawater, sacrificial anodes Al-Zn-In or zinc in seawater (Mg avoided), and the link between over-protection and cathodic disbondment of coatings

6Study coating failure diagnosis by visual cue: osmotic blistering (fluid blisters from residual salts), amine blush (sticky bloom from humid epoxy cure), mud-cracking (over-thick IOZ), alligatoring (hard over soft), filiform (worm tracks under thin film), outgassing pinholes (IOZ topcoated without mist coat)
