Answer
A Dispensation is an official, time-limited exemption granted by the Flag State Administration allowing a ship to sail or operate without fully complying with a specific statutory requirement (due to equipment breakdown, missing spares, or crew shortage).
Step-by-Step Application Process:
[Chief Engineer identifies defect] ──> [Company Technical/DPA Review] ──> [Official Flag State Submission] ──> [Class Survey & Conditional Issuance]
Technical Justification (The Chief Engineer’s Duty): You must write a detailed technical report explaining the breakdown, the troubleshooting already performed, the exact parts required, their delivery lead time, and the definitive date/port where the repair will be completed.
Company Intervention: The Technical Superintendent and DPA review the report and formally draft an application to the Flag State Administration (e.g., DG Shipping for Indian-flagged vessels).
Risk Assessment & Mitigation Measures: The application must include an risk assessment proving that the vessel can operate safely in its current state. For example, if a BWTS is dead, the mitigation is retaining ballast or exchanging it in deep sea. If an auxiliary engine is dead, the mitigation is ensuring the remaining generators can handle the maximum sea load with 100% redundancy.
Class Recommendation: The Flag State usually instructs the vessel’s Classification Society (Recognized Organization) to board the ship, carry out an inspection, and issue a formal statement confirming that the vessel is safe to proceed for a single voyage or a limited period (typically max 30 to 90 days).
Issuance of the Dispensation Letter: Once satisfied, the Flag State issues an official Letter of Dispensation. This document must be kept on the bridge/engine room and presented to any Port State Control auditor to prevent detention.
