APPLICATION The requirements apply to the surveys of the hull structure and piping systems in way of cargo holds, cofferdams, pipe tunnels, void spaces, fuel oil tanks within the cargo length area and all ballast tanks. The requirements contain the minimum extent of examination, thickness measurements and tank testing. When substantial corrosion, and/or structural defects are found, the survey is to be extended and is to include additional close-up surveys when necessary. In all cases the extent of thickness measurements is to be sufficient as to represent the actual average condition. Special consideration may be given to the extent of close-up surveys and/or thickness measurements in cargo holds as required for class renewal, intermediate or annual surveys, when all internal and external surfaces of hatch coamings and hatch covers, and all internal surfaces of the cargo holds, excluding the flat tank top areas and the hopper tank sloped plating approximately 300 mm below the side shell frame end brackets, have protective coating is found to be in good condition. Bulk Carrier Rules and Regulations - 30/06/07

Special consideration may also be given to existing bulk carriers, where Owners coat or re-coat cargo holds, in accordance with the Manufacturers’ recommendations. Nevertheless, prior to re-coating the cargo holds, scantlings are to be assessed in the presence of a Surveyor of the Society. Special consideration (or specially considered) is intended to mean as a minimum, that sufficient close-up inspection and thickness measurements are taken to confirm the actual average condition of the structure under the coating. …/… Bulk Carrier Rules and Regulations - 30/06/07

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. Bulk Carrier Rules and Regulations - 30/06/07

extent of the thickness measurements acceptance criteria
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 suspect areas/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. Bulk Carrier Rules and Regulations - 30/06/07

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. …/… Bulk Carrier Rules and Regulations - 30/06/07

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 Bulk Carrier Rules and Regulations - 30/06/07

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. Bulk Carrier Rules and Regulations - 30/06/07

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 Bulk Carrier Rules and Regulations - 30/06/07

CLASS RENEWAL SURVEY …/… Bulk Carrier Rules and Regulations - 30/06/07

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 Bulk Carrier Rules and Regulations - 30/06/07

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. Bulk Carrier Rules and Regulations - 30/06/07

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 in all 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. Bulk Carrier Rules and Regulations - 30/06/07

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.
