     8.
    Take tension leg drilling platform (TLPS) as an example


    Note: Also called jack-up platform, this type of platform is towed by a tug to the operating site, and the leg is raised to the seabed to fix it for drilling operations.
    After the operation is completed, the leg is retracted and then towed away.


    Some of the certifications or documents that the owner/manufacturer/supervisor may require are as follows:


    1.
    The inspection report of the workshop primer and the certificate of the classification society, which are the same as those of the ship;


    2.
    The third-party test report of coating performance under C5-M, Im2 and C5-M/Im2 corrosive environment, the minimum requirement is high durability according to ISO12944-6.
    At present, most of them are required to follow the test procedures in ISO20340/M501, which are higher than ship requirements.


    3.
    The inspection report or classification society approval certificate passed by the PSPC of the ballast tank coating is the same as that of the ship


    4.
    The inspection report of the drinking water tank coating or the Ministry of Health's product license for drinking water sanitation and safety, which is the same as that of ships


    5.
    Superstructure (living cabin, engine room) internal coating low-spread flame inspection report, the same as the ship


    6.
    Provide on-site technical service NACECIP2 or similar certificates of the same level, which is the same as that of ships


    7.
    Does the bottom of the platform need to use anti-fouling paint? At present, there is no final conclusion on whether it is used or not.
    Some owners require it, and some do not use it.
    If it is used, it will choose a variety with good static anti-fouling performance, and will require relevant certification and certification documents of anti-fouling paint, which is the same as that of ships.


    8.
    The coating on the legs below the water surface must have an inspection report (26 weeks or 4200 hours) or related certificates (note: the reinforcement of item 2) that is resistant to cathodic disbondment, which is similar to that of a ship.


    9.
    Performance of similar projects


    10.
    A written commitment to guarantee the protection period of 15-20 years

        Nine, the certification of marine coatings-several terms

      Nine, the certification of marine coatings-several terms


    1.
    IMO: International Maritime Organization, all ships at sea will have an IMO number


    2.
    IACS: International Association of Classification Societies.
    Marine ships must be classified, and some offshore platforms must also be classified.


    3.
    MSC: Maritime Safety Committee (a subsidiary of IMO)


    4.
    SOLAS Convention: Convention for the Safety of Life at Sea (mainly stipulating the safety and pollution prevention of ships)


    5.
    PSPC: refers specifically to the IMO "Performance Standard for Protective Coatings of Special Seawater Ballast Tanks for All Types of Ships and Double Side Side Spaces of Bulk Carriers".
    The 81st IMO Maritime Safety Committee (MSC81) approved the "Performance Standard for Protective Coatings at the Double Sides of Ships' Special Seawater Ballast Tanks and Bulk Carriers" (PSPC), and stipulated that this standard is applicable after July 1, 2008 All newly-built ships over 500 gross tonnage that have signed a construction contract.
    In the IACS common specification, it is required that bulk carriers with a length of 90 meters and above and oil tankers with a length of 150 meters and above that have signed a construction contract on or after the date when the IMO passes the coating standard (expected on December 8, 2006) must comply with the IMO The coating standard.

    Certification of marine coatings-certification of several key products

       10.
    Certification of marine coatings-certification of several key products


    The most critical, costly, long-period, and difficult to obtain certifications:


    1.
    Workshop primer


    2.
    Anti-fouling paint system


    3.
    PSPC (ballast tank coating performance)


    The above 3 must be present, otherwise it will not be able to enter the field of ship coatings (to make the whole ship)


    4.
    Cargo oil tank coating performance of crude oil ships: mainly for oil tankers, but it is not ruled out that it will be used in the fuel tanks of other ships.


    The classification society factory approval certificate will only list the products that have passed the product inspection and certification.

        11.
    Certification of Marine Coatings-Workshop Primer

      11.
    Certification of Marine Coatings-Workshop Primer


    1.
    Pass the inspection according to GB/T6747-2008 (normal production, type inspection once every 4 years);


    2.
    The introduction of PSPC and cargo oil tank standards puts new requirements on workshop primers.
    That is, the shop primer must pass the required performance test together with the subsequent epoxy coating.
    If it fails, at least 70% of the secondary surface treatment must be removed.


    3.
    In terms of offshore engineering, M501 stipulates that when the shop primer needs to be retained, the shop primer must also pass the corresponding test and qualification certification together with the subsequent main coating.


    After certification:


    ? 1.
    The classification society factory approval certificate will contain the certified workshop primer;


    ?2, the classification society issued the approval certificate of the corresponding workshop primer;


    ? 3.
    The inspection agency issues an inspection report;


    4.
    Those who have passed the PSPC or cargo oil tank performance certification will have an inspection report together with the main coating;


    ?5.
    IMO will record the shop primer + main coating that passed the PSPC test, and it will be available on the website.


    Note: Because shipyards tend to retain good workshop primers, it is unlikely that they will use workshop primers different from other parts for ballast tanks and cargo oil tanks.
    Therefore, there are currently only inspections or shipboards in items 1-3.
    Class society approval certificate, without the 4th certificate that passes the PSPC together with the main coating, it is difficult to sell the workshop primer to the shipyard.


     12.
    Certification of marine coatings-anti-fouling paint system

     12.
    Certification of marine coatings-anti-fouling paint system


    Certification basis:

    Certification of offshore and marine coatings-difficult points

     16.
    Certification of offshore and marine coatings-difficult points


    1.
    Many certificates have a validity period, and they need to be re-obtained when they expire;


    2.
    Many certificates need to be reviewed annually;


    3.
    The standards on which the certification is based are often updated, and the certification has to be re-obtained after each update;


    4.
    Product updates or new products must be re-inspected and certified.


    5.
    If the relevant agencies (IMO, IACS, etc.
    ) introduce new requirements, the products must be updated and re-certified.
    For example, since IMO/MSC passed the "International Convention on Safe and Harmless Ship Recycling" in May 2009, all countries (including China, which are currently under formulation) will soon launch the "Limited Standards for Hazardous Substances in Marine Coatings".
    The total amount of, VOC, hazardous heavy metals, toluene/ethylbenzene and xylene will be regulated, which may trigger the renewal and re-inspection and certification of ship coatings.
    Such standards may also be cited by offshore structures.
