How voyage optimisation protects margins in a CII-driven market

While CII is not a new regulation, its commercial consequences continue to intensify. A vessel’s carbon performance now shapes negotiations, influences fixture decisions, and can trigger financial penalties if ratings decline during the charter period. Charterers therefore require a way to balance profitability, timelines, and CII exposure without compromising commercial momentum.

Voyage optimisation sits at the centre of this balance. By grounding decisions in trusted data and transparent performance insights, charterers can confidently navigate the complex trade-offs between operational efficiency and commercial outcomes.

Moving beyond bunker savings 

There is a common misconception that optimisation is synonymous only with cutting fuel costs. While reducing fuel consumption is critical for lowering costs and emissions, it is not the only metric that defines a successful voyage. Focusing exclusively on bunker savings can sometimes lead to hidden losses.

Voyage optimisation requires a holistic view. Advanced technology combined with human expertise allows you to:

• Balance critical factors: Weigh bunker prices against market rates and commercial targets.
• Enable real-time decisions: Identify if slowing down to save fuel might cost more in lost time in a high-market environment.
• Optimise the supply chain: Create value for cargo owners, vessel owners and operators alike.

The ZeroNorth platform turns data into insights and actions, ensuring you maximise the profitability of the voyage as a whole delivering benefits for profit, people and planet.

The regulatory impact: Why CII is now a charterer’s concern

Historically, vessel efficiency was the shipowner's domain. However, the introduction of the Carbon Intensity Indicator (CII) has fundamentally altered this dynamic, creating a landscape where charterers now face tangible liability for a vessel’s carbon performance. We aim to make the complex clear.

The risk is real; a vessel that drops a letter rating during a charter period can trigger contractual penalties. Yet, this challenge also presents an opportunity to proactively manage scores through data-driven voyage optimisation. This approach allows you to:

• Simulate impact: See the CII impact of a voyage before it begins.
• Select the right strategy: Choose routes and speeds that meet commercial deadlines while protecting the rating.
• Track compliance: Track and report emissions effectively, transforming compliance from a burden into shared success.

Fix with confidence: the value of pre-fixture intelligence

Are you fixing based on paper promises or performance reality?

A persistent challenge in chartering is the discrepancy between a vessel's "brochure" description and its actual consumption. When these don't align, margins erode.

The solution is validated performance data.

Using ZeroNorth’s data ecosystem, you can assess a vessel’s true capability before you fix. This pre-fixture intelligence allows you to move beyond generic warranties and:

• Account for the variables: Instantly see the impact of hull fouling and weather history.
• Make better comparisons: Benchmark candidate vessels against one another with granular accuracy.
• Drive fairer negotiations: Base your charter party agreements on transparency and trust, not just static descriptions.

The futility of the 'claim game'

The post-voyage "claim game" is an effort-intensive process that often strains relationships. We believe in a more collaborative approach.

By sharing a single source of truth—a platform where both owner and charterer view real-time vessel performance data we can prevent underperformance before it escalates. Optimising the voyage collaboratively offers several advantages:

• Real-time alerts: Immediate notification if a vessel deviates from its warranted consumption.
• Corrective action: The ability to solve problems during the voyage rather than after.
• Partnership: Shifting the focus from apportioning blame to making global trade green together.

A clear direction forward

The industry is changing, and traditional methods are no longer sufficient to manage the complexities of modern chartering. ZeroNorth is a very clear direction. It points straight to a destination where technology and trusted data improve vessel performance and deliver real emission reductions.

We are proud to be a purpose-led organisation. By acting with confidence yet humility, we can navigate these complexities together. We invite you to join us in this transformation, ensuring your chartering strategy is profitable, fair and sustainable.

Frequently asked questions:

1. How does voyage optimisation benefit charterers beyond just fuel savings? 

While fuel efficiency is crucial, true voyage optimisation takes a holistic view to maximise overall profitability. By using advanced technology and trusted data, charterers can balance bunker costs against market rates and commercial targets. This approach ensures you are not losing money on time to save on fuel, ultimately optimising the supply chain for profit, people and planet.

2. How does the CII regulation impact a charterer’s liability? 

The introduction of the Carbon Intensity Indicator (CII) means charterers now face potential liability for a vessel's carbon performance during the charter period. To avoid contractual penalties or "pinco" clause disputes, charterers must proactively manage emissions. Data-driven tools allow you to simulate a voyage's impact on the CII rating before it begins, reducing the costs of compliance.

3. Why is independent vessel performance data critical before fixing a vessel? 

Relying solely on "brochure" descriptions can lead to overconsumption and unexpected costs. Accessing independent, trusted data helps charterers assess a vessel's true performance profile, including factors like hull fouling. Leveraging an ecosystem with billions of data points ensures you make informed decisions based on reality rather than theoretical specifications.

4. How can real-time data prevent post-voyage performance claims? 

The traditional "claim game" is effort-intensive and strains relationships. By adopting a collaborative approach and sharing a single source of truth, both owners and charterers can view real-time performance data. This transparency allows for immediate corrective action if a vessel deviates from its warranted performance, shifting the focus from apportioning blame to solving problems together.
