Answer
If a vessel causes a pollution incident just after leaving the dry dock (e.g., a leaking stern tube, a bottom plug not secured, or a sea chest valve failing), or may be from bunker tanks. As just coming out of DD, so all cargo tanks will be mostly empty. the financial and legal fallout is massive.
What applies and why:
MARPOL Annex I / Indian MS Act 2025: The Master must immediately execute the SOPEP (Shipboard Oil Pollution Emergency Plan) and report the incident to the coastal state authorities. Failure to report constitutes a criminal offense under the MS Act.
P&I Club (Protection and Indemnity): The ship's P&I insurance will immediately step in to cover the costs of pollution cleanup, third-party damages, and fines. Why? Because Hull & Machinery (H&M) insurance only covers physical damage to the ship itself. Pollution is a third-party liability, which falls strictly under P&I.
Subrogation (The Shipyard's Liability): Even though the P&I Club pays the immediate fines and cleanup costs to the Coastal State, the P&I Club will execute the principle of Subrogation. If the leak was caused by shipyard negligence (e.g., yard workers failed to tighten the bottom plug), the P&I Club will legally step into the shoes of the shipowner and sue the shipyard to recover the costs.
Bunkers Convention 2001 : These IMO conventions apply to ensure strict liability. They require the shipowner to maintain insurance (proven by a certificate carried onboard) to cover pollution damage.
