A Condition of Class (CoC) is a formal requirement or recommendation issued by a classification society after a ship’s survey, stating that certain deficiencies, damages, or issues must be rectified within a specified time frame to maintain the vessel’s class status.
In simple words, it’s a temporary permission to sail with the understanding that a specific problem or deficiency will be corrected by the due date.
✅ Why is a Condition of Class Issued?
A CoC is issued when:
- The ship has deficiencies or damages that do not immediately threaten safety but need attention.
- A surveyor notices wear and tear, corrosion, minor cracks, equipment non-compliance, or overdue maintenance during surveys or inspections.
- The vessel can continue operating but must comply within the given deadline to avoid suspension or withdrawal of class.
✅ What Happens If a Condition of Class Is Not Rectified in Time?
- The classification society may suspend or withdraw the ship’s class status.
- Port State Control inspections may detain the vessel.
- The vessel becomes commercially unattractive, as charterers and insurance companies require a vessel to be in full class.
✅ How Are CoCs Managed?
- All CoCs are listed in the vessel’s Quarterly Listing or in the class status report.
- They come with a clear description of the deficiency, assigned due date, and follow-up survey requirement.
- Once rectified, the owner must notify the class society, and a surveyor will verify and close out the CoC.
✅ Example of a Condition of Class Entry:
CoC No.: COC/OS/2023/04
Description: “Corrosion pitting found on main deck plating, port side, near frame 35. Requires repairs.”
Due Date: 30 June 2024
✅ Key Points to Remember:
- A CoC is not an immediate safety threat but a mandatory action item.
- Must be tracked by the owner/operator and closed out within the given time.
- Failure to comply can result in class suspension and serious commercial implications.
