Navigating Energy and Emissions

The importance of ship energy and greenhouse gas (GHG) emissions has grown significantly for vessel owners and charterers. With increasing regulatory pressures, charterers making decisions based on vessel emissions and ports offering incentives for cleaner ships, benchmarking a vessel's energy and emissions performance against peers has become common practice for many companies, driving technical and operational improvements.

The ABS Advantage

As the maritime industry navigates a rapidly changing regulatory landscape, ABS provides precise, data-driven insights to help clients stay compliant, competitive and cost-efficient. Leveraging global vessel datasets, advanced analytics and continuous specialist support, ABS delivers actionable roadmaps for decarbonization success, including:

Benchmark studies on efficiency and emissions
Design evaluations
Energy efficiency technologies
Powering performance assessments

Harvey Energy Tri-Fuel Vessel Shapes Future of Sustainability

The Harvey Energy will become the first ABS-classed dual fuel and battery vessel and the first U.S. flagged OSV equipped with a battery/converter system.

ABS Services

ABS applies proprietary tools to prepare peer group energy and GHG emissions insights through a comprehensive suite of services and solutions:

Peer-Group Benchmarking

For each peer group, the client specifies the following:

Containership
Bulk carrier
Tanker
Gas carrier
Liquefied natural gas (LNG) carrier
Combination carrier
General cargo ship
Refrigerated cargo carrier
Roll on/roll off (ro/ro) cargo ship
Ro/ro cargo ship (vehicle carrier)
Ro/ro (passenger ship)
Cruise passenger ship

Built within the years xxxx to yyyy. If no range is specified, then the range will be taken from 1980 to the present.

Analysis based on vessel size and operational capacity. The client will select the range from capacity xxxxxx to capacity yyyyyy.

For bulk carriers, tankers, containerships, gas carriers, LNG carriers, general cargo ships, refrigerated cargo carriers and combination carriers, deadweight tonnage (dwt) is used as capacity.

Gross tonnage (gt) is used as capacity for cruise passenger ships and ro/ros (cargo ships, vehicle carriers and passenger ships).

Evaluating metrics for a specific operational year starting from 2019.

Energy and Emissions Metrics

Deliverables for each peer group include graphs with metrics combining:

Energy
Fuel consumption
CO₂e
Automated emissions reduction (AER)
GHG fuel intensity (GFI)
Distance
Speed

Ship energy and greenhouse gas emissions have become important factors to vessel owners and charterers. ABS can assist you with your energy and emissions insights.
