About LionRock Maritime

LionRock Maritime provides highly accurate data and data-derived insights about tugboat operations across every port in the world. LionRock Maritime combines towage industry expertise, human creativity and data technologies to deliver decision-grade tugboat analytics software.

Executive Summary

Problem: Tugboat fuel consumption is strongly influenced by captains speeding patterns during transit and non-operational sailing, often referred to as lightsailing. Small deviations from optimal speed, especially during mobilisation and demobilisation, can accumulate into significant excessive fuel costs and CO₂ emissions. In many operations, this is not consistently measured and managed.
Solution: PowerCaptain enables structured monitoring of captain sailing behavior by tracking ECO-speed compliance across captains, tugs, ports, and jobs. It provides benchmarking, trend visibility, and feedback mechanisms that support more economical sailing.
Benchmarks: ECO-speed compliance is measured against defined baselines and categorized into “Good”, “Attention”, and “Intervention” to ensure consistent performance evaluation.
Typical Impact: Improved speed discipline leads to measurable fuel savings, reduced CO₂ emissions, and more consistent operational performance across ports.

Executive Answer

In harbor towage, a large share of fuel consumption occurs outside active towing, particularly during transit, standby, and repositioning.

Transit sailing speeds vary significantly between captains. Without structured monitoring and feedback:

Speeding often goes unnoticed
Performance differences remain hidden
Fuel inefficiencies accumulate over time

PowerCaptain addresses this by making sailing behavior measurable and comparable.

By tracking ECO-speed compliance across all operational levels, operators can:

Identify excessive speeding patterns
Benchmark captains and ports consistently
Create transparency and accountability
Influence behavior toward more economical sailing

The result is not about improved reporting, but active control over fuel consumption through behavioral management.

Common Causes / Issues in Capacity Planning

Lack of structured speed monitoring across operations
No visibility into captain-specific sailing behavior
Absence of standardized ECO-speed benchmarks
Limited linkage between speed behavior and fuel impact
Inconsistent feedback loops to captains
Difficulty comparing performance across ports and fleets

These gaps prevent operators from actively managing one of the most controllable drivers of fuel consumption.

Solution Overview: Managing and Optimizing Captain Sailing Behavior

Fuel measurement becomes powerful when it is linked to business decisions. The four dashboards shown above represent the core strategic use cases.

Step 1: Step 1: Company-Level Monitoring (Central Management View)

This view is designed for central management overseeing multiple ports.

It provides:

Aggregated KPIs (tugs monitored, fuel saved, cost reduction, CO₂ savings)
Lightsailing performance trends across ports
Weekly/daily/monthly trend tracking

This allows management to:

Track performance development over time
Monitor fuel savings and efficiency improvements
Identify overall behavioral trends rather than isolated cases

Step 2: Savings Tracking Across Ports

This section shows fuel savings development per port over time.

Key functionality:

Weekly fuel savings tracking
Port-level contribution to total savings
Trend comparison across periods

This enables:

Clear visibility into which ports are improving
Tracking of fuel efficiency gains over time

Linking behavioral change directly to financial impact.

Step 3: Port-Level Performance Monitoring

The port performance view provides:

ECO-speed compliance vs baseline
Fuel saved per port
Performance classification (Good / Attention)
Number of jobs and captains involved

This enables port managers to:

Identify underperforming ports
Compare actual vs baseline performance
Focus attention where intervention is needed

Step 4: Detailed Port View & Trend Analysis

Within each port, users can:

Analyze lightsailing performance trends over time
View speed distribution across intervals

Frequently Asked Questions

Why is sailing speed during transit such an important driver of fuel consumption?

A significant portion of tugboat fuel consumption occurs during transit, standby, and repositioning rather than active towing. During these phases, speed is largely determined by captain's decisions. Even small increases above optimal speed can lead to disproportionately higher fuel usage. By managing this behavior, operators can directly influence one of the most controllable components of fuel cost.

How does PowerCaptain help improve ECO-speed compliance?

PowerCaptain provides clear visibility into sailing behavior across captains, tugs, and ports. It tracks ECO-speed compliance, benchmarks performance, and highlights where speeding occurs. By combining this with rankings and trend analysis, it creates transparency and accountability, which supports behavioral change and encourages more economical sailing practices.

Can PowerCaptain be used to manage performance across multiple ports?

Yes. PowerCaptain enables centralized monitoring of ECO-speed compliance across all ports. Management can track trends, compare performance, and identify where improvements are needed. At the same time, users can drill down into individual ports, captains, or tugs to understand the underlying drivers of performance.

How does PowerCaptain link speed behavior to fuel and CO₂ savings?

The platform connects speed data with fuel consumption models to estimate the impact of sailing behavior. Improvements in ECO-speed compliance are translated into fuel savings and corresponding CO₂ reductions. This allows operators to quantify the financial and environmental benefits of improved captain behavior and track progress over time.
