Cost-benefit sharing framework for energy efficiency investments

Introduction

Maritime is a central part of sustainable global supply chains due to its low energy consumption per ton-mile goods transported. 

Sustainable maritime decarbonization is only achieved by transitioning to energy and fuels with low well-to-wake emission footprints. No single sustainable fuel can meet the global fleet’s demand. Sustainable energy and fuel production is part of the larger energy transition. Maritime’s fuel choices will be influenced by cross-sector demands and energy infrastructure build-out.

The challenge of scaling sustainable fuel production makes energy efficiency improvements of the global fleet essential to achieve net-zero in 2050. The needed energy efficiency technologies and operational solutions for improving energy efficiency of the fleet exists today, however they are not experiencing system-wide adoption in today’s commercial setting. 
 
While regulatory framework on energy efficiency is being reviewed in light of the revised IMO GHG strategy ambition and specific targets towards 2030 and 2040; there are potential avenues fitting today’s commercial setting that the industry actors mainly – Ship Owners, Ship Charterers and Ship Managers can choose and deploy. 

 

Project objective

The project will provide a guideline to help eliminate the barriers that prevent a wider adoption of energy efficiency technologies in international shipping. These barriers are not specific to ship types or contractual constructs between multiple parties of influence and are common across the industry. Well known barriers are: 

  • Misaligned incentives between stakeholders who have influence on a ship’s energy efficiency upgrade/ retrofitting e.g. divergent approaches to ships’ technical or operational energy efficiency among Ship Owner, Ship Charterer, Cargo Owners, and/ or Technology Provider. 

  • Lack of transparency and standardization for calculating and verifying benefits from EET implementation 

  • Ambiguity of roles and responsibilities among stakeholders, preventing optimal performance of EETs after installation and during their operational lifetime

  • Consequently, there is no platform for Ship Owners, Ship Charterers, Technology Providers, and Cargo Owners to establish shared cost and benefit agreements that could promote faster adoption of EETs onboard an existing fleet. 

 

This project aims to provide a toolbox consisting of two guideline documents outlining steps to take when upgrading a fleet’s energy efficiency through EET retrofits and financed by a cost-benefit sharing model. The guidelines cover: 

  • A technical methodology to document, monitor and verify benefits from an EET upgrade

  • A contractual template for cost-benefit sharing between a Ship Owner & a Ship Charterer as part of a Time Charter party agreement 

 

The guidelines are based on operational experience and real-world use cases. Concepts will be demonstrated to work in practice through pilot projects with MMMCZCS’s partners.

Project highlights and outputs


1. Technical Guideline for EET benefit tracking

This guide provides the MMMCZCS’s recommended best-practice procedures for tracking the benefits of EETs retrofitted to existing vessels to reduce propulsion power requirements. The procedures include calculating fuel savings with a sufficient level of confidence and transparency to support each party’s own commercial decision making on cost-benefit sharing.

2. Pilots with the Center and industry partners

The pilot cases represent the practical, real‑world foundation of this project. The scopes have been developed in close collaboration with our industry partners. Our pilots test Energy Efficiency Technologies (EETs) directly on operating vessels, demonstrating how the project concepts work outside a theoretical setting.

Through the live industry cases, partners are evaluating the technical performance of EETs, validate the benefit‑tracking methodology, and explore how collaborative commercial models can support wider adoption. The pilots also strengthen cooperation across the value chain, bringing together Ship Owners, Ship Charterers, Technology Providers, and other stakeholders to jointly overcome barriers and unlock the full potential of EET across the industry.

The insight from these pilots will directly support the broader goal of accelerating adoption of energy‑efficiency upgrades across the global fleet.

3. A common framework for owners & charters to agree on cost-benefit sharing

The work towards a common framework is one of the key highlights of the two project phases.

Close collaboration & evaluation with project partners, have shown that such a framework is needed to reflect real operational conditions, commercial realities, and the diverse perspectives of industry stakeholders.

The purpose of a collaboration framework is to provide a standardized, user‑friendly structure that can help Ship Owners and Ship Charterers to align on incentives, clarify responsibilities, and simplify negotiations.

By agreeing on clear principles for how costs and efficiency gains can be shared, we can support more predictable and scalable commercial arrangements coming into force and that accelerate investments in fleet energy‑efficiency upgrades.

Pilot examples


Seaspan & Hapag Lloyd

The two companies have agreed to initiate a joint pilot project centered on a single Seapan vessel undergoing dry dock, during which it will receive a series of energy‑efficiency upgrades of varying scale. The purpose of the pilot is to establish a structured, data‑driven approach to tracking both costs and benefits arising from these upgrades, enabling the parties to evaluate how benefits can be shared in a transparent and balanced manner.

The pilot will rely on performance data collected from the vessel before and after the dry dock period. VPS will act as the independent third‑party verifier, supporting both parties in the handling, validation, and interpretation of data. Once the upgraded vessel returns to service, its operational performance will be monitored over a defined period, forming the basis for a tabletop exercise in which the two companies jointly assess how the measured benefits can be allocated.

The charterparty addendum will serve as the foundational framework for this cost‑benefit sharing assessment. Through the pilot, the partners aim to test how such an agreement can be practically applied, creating a clearer understanding of how commercial models for energy‑efficiency investments can be adapted to support collaboration and mutually beneficial outcomes.

DP World, VPS & MPC Containers

The Center worked with DP World shipping solutions, MPC Container Ships and VPS to demonstrate how energy‑efficiency upgrades can be supported through a transparent cost‑sharing model. DP World shipping solutions and MPC C jointly invested in several technical improvements on an MPC Container owned, DP World shipping solutions‑chartered vessel and agreed to share both installation costs and any resulting fuel‑saving benefits through an amended Charter Party.

VPS monitored the performance improvements, while all partners contributed insights on how the agreement was structured and implemented. This collaboration aimed to show case and present a cost‑benefit sharing framework that can be applied more broadly across the shipping industry.

This specific pilot highlights and underline the real potential of collaboration and data driven decision‑making, however also show the need for a data driven cost benefit‑tracking model & charter‑party guidance.

Total Energies

TotalEnergies and MMMCZCS collaborating to evaluate the impact of an engine‑optimizer software system currently being tested on one of TotalEnergies’ chartered vessels.

The pilot focused on assessing the fuel‑saving potential of the technology in real operating conditions. By carrying out the study together, the teams gained practical insight into how the Phase I guideline procedures apply to this type of Energy Efficiency Technology (EET).

In addition to documenting the system’s performance, the collaboration also explored how such technologies should be incorporated into a transparent and balanced cost‑benefit sharing framework. The findings provide both parties with a clearer, evidence‑based foundation for evaluating similar EETs going forward.
