On-Deck Shipment

On-Deck Shipments: Risks, Regulations & Best Practices in Maritime Logistics

On-deck shipments involve transporting cargo on a vessel’s open deck, exposing goods to weather and sea risks. This guide covers key considerations, legal frameworks (e.g., UCP 600), and strategies for safe, compliant operations.


What is On-Deck Shipment?

On-deck cargo is loaded above deck instead of in enclosed holds. Common for:

  • Oversized Items: Wind turbine blades, machinery.
  • Perishables: Requiring ventilation.
  • Specialized Cargo: Yachts, project cargo.

Key Risks: Weather exposure, shifting during transit, limited insurance coverage.


Legal Responsibilities & Liability

Shipowner Obligations

  • Ensure seaworthiness and proper lashing/securing.
  • Comply with Hague-Visby Rules (if B/L clauses permit on-deck transport).
  • Document cargo stowage in bills of lading (B/L) and charter parties (C/P).

Insurance & Liability Limits

  • Carrier Liability: Excluded unless negligence proven (e.g., improper securing).
  • Insurer Coverage: Often limited for on-deck cargo; requires explicit clauses.

UCP 600 Compliance for On-Deck Shipments

Article 26 Rules:

  • Transport documents cannot state “goods will be on deck” (banks reject such B/Ls).
  • Documents may state “goods may be on deck” if credit allows.
  • Exceptions: Perishables/hazardous materials requiring on-deck stowage.

ICC Opinion TA827rev

  • Copies of B/Ls aren’t deemed non-compliant under UCP 600.
  • Always mark perishable on-deck cargo; reject B/Ls if credit prohibits it.

Best Practices for Safe On-Deck Transport

  1. Secure Stowage: Use lashings, twist locks, and dunnage to prevent shifting.
  2. Weather Protection: Tarpaulins or waterproof covers for sensitive cargo.
  3. Crew Training: Regular drills on securing techniques and risk assessment.
  4. Documentation: Clearly state on-deck status in B/Ls and C/P agreements.
  5. Inspections: Pre-departure and mid-voyage checks for lashing integrity.

FAQ: On-Deck Shipment Essentials

Q: Is on-deck cargo covered by marine insurance?

A: Limited coverage unless explicitly included in the policy.

Q: How does UCP 600 affect letters of credit?

A: B/Ls must avoid definitive on-deck statements unless permitted by the credit.

Q: Can carriers avoid liability for on-deck cargo damage?

A: Yes, if stowage complies with contractual terms and no negligence is proven.


Conclusion: Mitigating On-Deck Risks

On-deck shipments offer flexibility for bulky cargo but require meticulous planning. Prioritize:

  • Compliance: Align with UCP 600 and Hague-Visby Rules.
  • Safety Protocols: Robust securing and crew training.
  • Transparency: Clear B/L terms to avoid disputes.
