COATING► PROTECTIVE COATING

• Ballast tanks, cargo/Ballast holds and upper and lower part of cargo old of bulk carrier cargo ( new construction) have to be HARD COATED

Other coatings may be considered provided that they are applied in accordance with the manufacturer’s specification and maintained

SOFT COATINGS ARE NOT ACCEPTABLE

► COATING CONDITION

• GOOD

- Only minor spot rusting

• FAIR

- Local breakdown at edges of stiffeners and weld connections

- Light rusting over less than 20% or more of area under consideration

• POOR

- General breakdown of coating over 20% area under consideration

- Hard scale over more than 10% area under consideration



►Prompt and thorough repair (requirements extended to all types of ships)

• A "Prompt and thorough repair" is a permanent repair completed at the time of survey to the satisfaction of the Surveyor, therein removing the need for the imposition of any associated recommendation.

• Any damage in association with wastage over the allowable limits (including buckling, grooving, detachment or fracture), or extensive areas of wastage over the allowable limits, which affects or, in the opinion of the Surveyor, will affect the ship's structural, watertight or weathertight integrity, is to be promptly and thoroughly repaired.

CLASS RENEWAL SURVEY

Survey programme and preparation for survey

The Owner in cooperation with the Society is to work out a specific Survey Programme prior to the commencement of any part of:

the class renewal survey

the intermediate survey for bulk carriers over 10 years of age

The survey is not to commence until the Survey Programme has been agreed.

The survey programme at intermediate survey may consist of the survey programme at the previous class renewal survey supplemented by the hull condition evaluation report of that class renewal survey and later relevant survey reports.

The survey programme is to be worked out taking into account any amendments to the survey requirements after the last class renewal survey carried out.




Survey planning meeting

The establishment of proper preparation and the close co-operation between the attending surveyor(s) and the owner's representatives onboard prior to and during the survey are an essential part in the safe and efficient conduct of the survey. During the survey on board, safety meetings are to be held regularly.

Prior to commencement of any part of the renewal and intermediate survey, a survey planning meeting is to be held between the attending surveyor(s), the owner's representative in attendance, the thickness measurement company operator(s) (as applicable) and the master of the ship for the purpose to ascertain that all the arrangements envisaged in the survey programme are in place, so as to ensure the safe and efficient conduct of the survey work to be carried out.



CLASS RENEWAL SURVEYSurvey planning meeting

The following is to be addressed in the meeting:

schedule of the ship (i.e. the voyage, docking and undocking manoeuvres, periods alongside, cargo and ballast operations, etc.)

provisions and arrangements for thickness measurements (i.e. access, cleaning/de-scaling, illumination, ventilation, personal safety)

extent of the thickness measurements

acceptance criteria

extent of close-up survey and thickness measurements considering the coating condition and suspectareas/areas of substantial corrosion

execution of thickness measurements

taking representative readings in general and where uneven corrosion/pitting is found

mapping of areas of substantial corrosion, and

communication between attending surveyor(s), the thickness measurement company operator(s) and owner representative(s) concerning findings.




► Scope of Survey

In addition to the requirement of Annuals Surveys, all cargo holds, ballast tanks, including double bottom tanks, double side tanks as applicable, pipe tunnels, cofferdams and void spaces bounding cargo holds, decks and outer hull are to be examined, and this examination is to be supplemented by thickness measurement and testing required to ensure that the structural integrity remains effective. The aim of the examination is to discover substantial corrosion, significant deformation, fractures, damages or other structural deterioration that may be present.

All piping systems within the above spaces are to be examined and operationally tested to working pressure to attending Surveyor's satisfaction to ensure that tightness and condition remain satisfactory.

…/…




…/… The survey extent of ballast tanks converted to void spaces will be specially considered by the Society in relation to the requirements for ballast tanks.

A bottom survey in dry condition is to be a part of the class renewal survey. The overall and close-up surveys and thickness measurements, as applicable, of the lower portions of the cargo holds and ballast tanks are to be carried out during this bottom survey in accordance with the applicable requirements for class renewal surveys, if not already performed.Lower portions of the cargo holds and ballast tanks are considered to be the parts below light ballast water line

…/…




…/…

Where provided, the condition of the corrosion prevention system of ballast tanks is to be examined.For ballast tanks, excluding double bottom tanks, where a hard protective coating is found in poor condition, and it is not renewed, where soft coating has been applied, or where a hard protective coating has not been applied from the time of construction, the tanks in question are to be examined at annual surveys. Thickness measurement are to be carried out as deemed necessary by the Surveyor.

…/…




…/…

When such a breakdown of hard protective coating is found in water ballast double bottom tanks and it is not renewed, where a soft coating has been applied, or where a hard protective coating has not been applied from the time of construction, the tanks in question may be examined at annual surveys. When considered necessary by the Surveyor, or where extensive corrosion exists, thickness measurement are to be carried out.

Where hard protective coating in cargo holds is found in good condition, the extent of close-up surveys and thickness measurements may be specially considered



CLASS RENEWAL SURVEY …/…




Hatch Covers and Hatch Coamings

A survey of the items listed for Annual Surveys is to be carried out, in addition to all hatch covers and coamings.

Checking of the satisfactory operation of all mechanically operated hatch covers is to be made, including:

stowage and securing in open condition

proper fit and efficiency of sealing in closed condition

operational testing of hydraulic and power components, wires, chains, and link drives.

Checking the effectiveness of sealing arrangements of all hatch covers by hose testing or equivalent.

The close-up survey and thickness measurements




Thickness Measurement

The extended thickness measurements are to be carried out before the survey is credited as completed.

Suspect areas identified at previous surveys are to be examined. Areas of substantial corrosion identified at previous surveys are to have thickness measurements taken.

The Surveyor may further extend the thickness measurements as deemed necessary.

When pitting is found on bottom plating and its intensity is 20% or more, thickness measurements are to be extended in order to determine the actual plate thickness out of the pits and the depth of the pits. Where the wastage is in the substantial corrosion range or the average depth of pitting is 1/3 or more of the actual plate thickness, the pitted plate is to be considered as a substantially corroded area.





For areas in tanks where hard protective coatings are found to be in a good condition the extent of thickness measurements may be specially considered by the Society.

For single skin bulk carriers, representative thickness measurements to determine both general and local levels of corrosion in the shell frames and their end attachments inall cargo holds and water ballast tanks is to be carried out.

For double skin bulk carriers, representative thickness measurement to determine both general and local levels of corrosion in the transverse web frames in all water ballast tanks is to be carried out.





Thickness measurements is also to be carried out to determine the corrosion levels on the transverse bulkhead plating.

The extent of thickness measurements of the transverse bulkheads may be specially considered provided the Surveyor is satisfied by the close-up survey, that there is no structural diminution, and the hard protective coating where applied remains efficient.
