Arbitration Involving Shipboard Emissions-Capture Retrofitting Disputes

1. Introduction

Shipboard emissions-capture retrofitting disputes arise when shipowners, shipyards, engineering companies, equipment manufacturers, financiers, and technology licensors disagree over the installation, performance, cost, or regulatory compliance of onboard carbon capture systems.

Shipboard carbon-capture retrofits (often called Onboard Carbon Capture and Storage — OCCS) involve installing equipment that captures CO₂ from ship engines and exhaust systems before release into the atmosphere. The technology requires integration between:

• main engines;
• exhaust gas systems;
• carbon capture units;
• liquefaction equipment;
• storage tanks;
• monitoring and verification systems.

International maritime regulators are developing frameworks for OCCS, including technical standards for testing, certification, measurement, and verification.

Because retrofit projects involve multiple jurisdictions and highly technical engineering obligations, arbitration is frequently selected for resolving disputes.

2. Nature of Shipboard Emissions-Capture Retrofit Disputes

A. Engineering Design Failure Disputes

Example:

A shipowner contracts with a marine engineering company to install an emissions-capture system.

Contract requirements:

• capture 80% of CO₂ emissions;
• maintain vessel speed;
• avoid excessive fuel consumption;
• complete installation during dry dock.

After installation:

• capture efficiency is only 45%;
• engine performance declines;
• vessel operations are disrupted.

The arbitration issues become:

• Was the design defective?
• Were performance guarantees breached?
• Did the owner provide inaccurate vessel data?

B. Delay in Retrofit Completion

Ship retrofits often must occur during limited dry-docking periods.

Disputes may involve:

• missed installation deadlines;
• loss of charter income;
• increased docking expenses;
• regulatory penalties.

The tribunal examines:

• project schedules;
• contractor responsibility;
• delay notices;
• mitigation efforts.

C. Cost Overrun Disputes

Carbon-capture retrofits involve expensive modifications.

Common disputes:

• unexpected structural reinforcement costs;
• additional piping requirements;
• increased energy consumption;
• redesign expenses.

Questions include:

• Who bears unforeseen costs?
• Was the contract fixed-price or cost-plus?
• Did the owner approve variations?

D. Performance Guarantee Claims

Technology providers may guarantee:

• CO₂ capture percentage;
• energy efficiency;
• operational reliability.

Failure may lead to claims for:

• damages;
• replacement;
• repair;
• termination.

E. Regulatory Compliance Disputes

OCCS projects must interact with:

• IMO environmental rules;
• classification society requirements;
• national maritime authorities;
• carbon-accounting regimes.

Future disputes may concern whether captured CO₂ qualifies for emissions reduction calculations.

3. Arbitration Issues

1. Jurisdiction and Arbitration Clause

Ship retrofit contracts often include:

• London arbitration;
• Singapore arbitration;
• ICC arbitration;
• ad hoc UNCITRAL arbitration.

Disputes may arise regarding:

• whether subcontractors are bound;
• whether technology licensors are parties;
• whether warranty disputes fall within arbitration.

2. Applicable Law

A retrofit agreement may involve:

• shipowner in Greece;
• shipyard in China;
• technology supplier in Norway;
• financing bank in Singapore.

The tribunal must determine:

• governing contract law;
• applicable maritime law;
• environmental obligations.

3. Expert Evidence

Arbitrators commonly rely on:

• naval architects;
• marine engineers;
• emissions specialists;
• classification experts.

Technical questions include:

• capture efficiency;
• energy penalty;
• safety compliance;
• vessel stability.

4. Force Majeure Issues

Contractors may argue:

• supply shortages;
• equipment manufacturing delays;
• regulatory changes;
• unavailable storage infrastructure.

The tribunal examines whether such events were foreseeable.
