After the completion of each stage (blasting, sweeping, scraping, etc.) and before painting,
area will be inspected and approved by Owners Representative and Painting company
representative (including dry film thickness measurements).
All the hull paints shall be Owners supply.
The surface preparation and the application of paint shall be in accordance with the paint
manufacturers recommendations and the requirements of the Manufacturers
Representative who will be present all that time (paint maker product data sheets are to be
strictly followed.
The entire exterior surface of the hull, keel to rail, stern to bow including rudder and
propeller shall be thoroughly cleaned by high pressure ( minimum 300 bar) fresh water to
remove all scale, loose paint back to firm edge, marine growth, salt crystals and other
foreign substances. Sufficient hose length and access shall be provided to enable jet nozzles
to be not more than 30 cm from hull surface. After HPFW cleaning the salt content on the
hulls surface shall not be more than 50 mg/m2.
Areas contaminated with oil or grease shall be degreased using soluble detergent
compatible with paint in use and thoroughly rinsed.
All blasting shall be done by clean grit or other suitable material used by the shipyard
propelled by clean, dry, oil free air. During blasting the Contractor shall close off all
ventilators, doors, sea valves inlets, etc. to prevent the ingress of grit.
Abrasive material shall be new and not recycled.
Effective precaution shall be taken to prevent grit entering rudder and propeller shaft
bearings.
The sides of the vessel shall be protected (handrails on deck) with suitable material in order
to protect the main deck from being contaminated with abrasive material (plywood or
other).
No blasting shall take place in the vicinity of wet paint or in the vicinity of the vessel (same
dry dock) after blasting for this vessel will have been completed and steel surfaces cleaned
(dry air, fresh water hose down washing).
If blasted surfaces have rusted prior to painting, then re-blasting will be required.
Prior to painting, ships side scuppers shall be plugged and any overboard discharges in use
shall be carried clear of hull via plugs fitted with hose, pipes or equivalent which conduits
shall be carried down to the dock bottom. Allow for access as required. Paint shall be
applied only to perfectly dry surfaces, free from dust, salt crystal fouling, loose paint,
cleaning residue and other impurities in accordance with paint manufacturers
requirements.
When more than one coat is specified, subsequent coats shall not be applied until preceding
coat has sufficient curing/drying time in accordance with the time interval recommended by
the paint manufacturer. The same applies for immersion time upon completion of the
underwater bodys coating work.
If condensation appears on the outer shell of blasted tanks the Owners Representative
should be consulted regarding the draining of such tanks before recoating commences.
Where blasting is carried out edges of existing paints are to be feathered to allow
for proper bonding of new paint + to ensure all loose paints is removed. Feathering
can be achieved by either blasting or disc papering.
Page 27
Technical Specification for the 1st Special Survey of STX HN 1245-6
Dry film thickness measurements shall be carried out prior to application of each coating.
Obtained values significantly lower (15%) than the design values described in these
specifications, will require additional coating with the same paint until design values have
been reached. In such cases additional paint will have to be supplied from the Contractor at
his account.
Cost increase from delays resulting (additional days in the dry dock, delayed delivery, etc.)
from wrong application of the coating system, resulting into re-application of the same coat
will not be accepted from the Owner.
The paint manufacturers representative and paint data sheets requirements are to be
followed to ensure correct surface preparation and paint application. The paint
manufacturers recommendations with respect to spray equipment pressure, nozzle tip size,
spray angle and paint film thickness will be strictly adhered to. Film thickness shall be
continuously monitored to ensure that over thickness and under thickness is held to a
minimum. Sags, runs, spray dusts and overspray shall be avoided or brushed out. If not,
Owners Representative reserves the right to require re-blasting and refinishing of affected
area. All anodes and transducers as well as propeller shall be protected against paint by
grease soft soap or masking tape.
Since the new IMO rules antifouling paints are to be used, the classification society will
need to issue an antifouling statement of compliance certificate. This will confirm
compliance with the new IMO rules for antifouling paints. Any requirements of the Class
surveyor should be adhered to during the hull treatment and paint application to allow the
issuance of such a certificate
