MARPOL & ENVIRONMENTAL COMPLIANCE

Project Manager control of pollution-prevention systems, waste handling and environmental compliance

Refit work can create environmental risks through oily bilge water, sewage, garbage, chemicals, coatings, solvents, fuel, lubricants, tank cleaning, blasting residues and emissions.

The Project Manager is not the Flag Administration, environmental authority or statutory surveyor. The PM’s role is to coordinate the work, identify environmental risks, maintain awareness of applicable MARPOL requirements, control subcontractor activities and ensure that waste, discharges and pollution-prevention systems are properly managed during the refit.

MARPOL addresses pollution from ships through six technical Annexes. These cover oil, noxious liquid substances in bulk, harmful substances in packaged form, sewage, garbage and air pollution. Most Annexes also include special areas where stricter discharge controls may apply. 

Key responsibilities

• Confirm the yacht’s Flag, Class and applicable environmental regime.
• Identify MARPOL Annexes relevant to the vessel and planned work.
• Review pollution-prevention systems affected by the refit.
• Identify oily-water, sewage, garbage and hazardous-waste streams.
• Establish waste-segregation arrangements before work begins.
• Confirm approved shore reception facilities where required.
• Prevent uncontrolled discharge of oil, chemicals, sewage or garbage.
• Coordinate oily-bilge and sludge handling.
• Control fuel and lubricant transfer operations.
• Establish spill-prevention and spill-response arrangements.
• Ensure absorbent materials and spill kits are available.
• Coordinate sewage-system work and temporary arrangements.
• Maintain separation between hazardous and non-hazardous waste.
• Control paint, solvent, blasting and chemical waste.
• Prevent plastics and other prohibited garbage from entering the sea.
• Coordinate tank cleaning and residue disposal.
• Confirm emissions-related equipment is not modified without appropriate technical review.
• Maintain waste-transfer notes, receipts and disposal documentation.
• Record environmental incidents and corrective actions.
• Coordinate Flag, Class, port or environmental-authority involvement where required.
• Confirm pollution-prevention systems are reinstated and tested before redelivery.

MARPOL Annex V generally prohibits discharge of garbage into the sea except for limited specified exceptions, and it applies broadly to ships including pleasure craft and yachts.

PROJECT MANAGER COMPETENCY TEST

Scenario 1 — Oily Bilge Water

During refit work, a bilge contains water contaminated with oil and cleaning residues. A subcontractor suggests pumping it directly overboard because the yacht is stationary in the yard.

Question:
What should the Project Manager do?

A. Allow discharge because the yacht is not underway
B. Stop the discharge and arrange handling in accordance with the applicable pollution-prevention requirements and yard procedures
C. Dilute the bilge water first
D. Pump it out at night

Correct answer: B

Why:
Operational circumstances do not remove pollution-prevention obligations. Oily waste should be handled using the vessel’s compliant systems or approved shore reception arrangements as applicable. 

Scenario 2 — Garbage

A contractor proposes throwing plastic packaging into the harbour waste stream because it is “only a small amount.”

Question:
What is the correct response?

A. Allow it if the packaging is clean
B. Segregate and dispose of the waste through the proper shore-side system
C. Cut it into smaller pieces
D. Burn it onboard

Correct answer: B

Why:
MARPOL Annex V generally prohibits the discharge of plastics into the sea and requires controlled handling of ship-generated garbage. 

Scenario 3 — Sewage System

The yacht’s sewage-treatment system is out of service during refit, and the temporary arrangement has not been documented.

Question:
What should the Project Manager do?

A. Ignore the issue until sea trials
B. Establish and document a compliant temporary arrangement before use
C. Discharge directly into the harbour
D. Ask the crew to minimise toilet use

Correct answer: B

Why:
Sewage discharge is controlled under MARPOL Annex IV, subject to the vessel’s applicable regime and operating conditions. Temporary refit arrangements should therefore be controlled rather than improvised. 

Scenario 4 — Waste Documentation

Several drums of contaminated paint residue have been removed from the yacht, but no disposal receipt or waste-transfer record can be found.

Question:
What should the Project Manager do?

A. Close the work package because the drums have left the yard
B. Obtain appropriate disposal documentation and maintain traceability of the waste stream
C. Ask the subcontractor to confirm verbally
D. Delete the item from the waste register

Correct answer: B

Why:
Environmental control during a refit should include traceability of hazardous and regulated waste from generation through authorised disposal.

MODULE COMPLETION

Before completing this module, the Project Manager should be able to:

• understand the importance of plastics control
• identify common hazardous-waste streams
• establish spill-prevention and response arrangements
• coordinate approved shore reception and waste disposal
• maintain waste and disposal traceability
• understand when Flag, Class, port or environmental authorities may need to be involved
• ensure pollution-prevention systems are reinstated before redelivery
