Cost calculation

The OPS calculation tool permits calculation of the overall costs of a project under study. It calculates operational and investment costs and provides a means of assessing the effects of optimizing parameters like berth occupancy, electricity supply costs, fuel costs and so on… Cost calculation »

Costs

As the available examples and studies show, the required investments may vary considerably, depending on the local situation. In addition, cost calculations for RoRo terminals are different from those for container or bulk terminals… Costs »

Emission calculation

The OPS calculation tool provides a means of calculating the overall emissions reductions to be achieved by a given OPS project. In the tool, the energy source serves as a variable, allowing emission cuts to be calculated for several alternative scenarios… Emission calculation »

OPS calculation tool

This website offers a simple calculation tool that helps develop a feeling for the costs and benefits of OPS. The tool is filled out with characteristic data, but can be readily adapted to the local situation by changing the cost figures and data on the number of ships and their fuel consumption… OPS calculation tool »

Stepwise approach

Implementation of OPS requires input of plenty of detailed local data from the various stakeholders mentioned above and careful planning and study.Feasibility study There are many examples of feasibility studies being undertaken prior to implementation of an OPS project… Stepwise approach »

Step 1: Plan

1. Take advantage of the experience and knowledge available at other ports,    in reports and at authorities on OPS. 2. Find out what vessel fleet in your port would be most suitable for OPS,        preferably frequent-calling vessels with long port stays and offering the    greatest emission reduction potential… Step 1: Plan »

Step 2: Do

1. Select the vessel fleet/shipping line with the greatest cost effectiveness     and environmental benefits. 2. Choose the appropriate technical solution 3. If possible, purchase energy produced from a renewable energy source to    achieve a maximum environmental net benefit… Step 2: Do »

Cost effectiveness

The cost effectiveness of environmental measures is given by the ratio between their costs and benefits, the latter expressed in terms of avoided emissions. This yardstick allows different measures to be compared… Cost effectiveness »

Environment & health

Air quality and health concerns are the main reasons for installation of OPS in ports. This section provides an overview of the environmental and health benefits of OPS, while at the same time providing a brief description of alternative techniques… Environment & health »

Climate

Implementation of OPS provides an opportunity not only to improve air quality, but also to reduce emissions of carbon dioxide, one of the main contributors to global warming. By switching from fuel oil to gas as an energy source or, better still, to sustainably generated wind power, for example, CO2 emissions can be curbed… Climate »

Air quality

The switch from onboard-generated electricity to OPS will benefit local air quality significantly, as local emissions will be all but eliminated. These emissions will be replaced by lower emissions more remote from residential areas… Air quality »
