Ship energy efficiency

Measures for ship design and operation to save costs and meet decarbonization requirements

Energy efficiency driven by compliance 

To remain operative and competitive, ship owners and operators must capitalize on energy efficiency. Decreasing energy consumption will reduce the associated greenhouse gas (GHG) emissions. The IMO is regulating and monitoring GHG emissions through multiple indexes, KPIs, plans, and reporting schemes such as EEDI and EEXI, EEOI, CII and SEEMP.

Voluntary standards such as the ISO 50001 and CSI (Clean Shipping Index) or company specific KPIs are becoming more commonly used to demonstrate to third parties the achievements made in reducing consumption.

Energy efficiency driven by profitable ship operations

Emerging technologies can be used to operate smarter, saving both fuel and costs. Determining the measure, technology, or energy source (fueltype -wind-assisted or solar-based balance) that suits your fleet or ship requires in-depth knowledge and experience.

Accurate maritime data can have a profound impact on the way ship operators and owners monitor the safety, sustainability and performance of their vessels. However, obtaining and extracting the maximum potential from this vast amount of data can be challenging.

New fuels can also have a lower energy density and be more expensive. This can require improved route planning and optimization of the on-board energy consumers.
