Energy-efficiency

Working with energy-efficiency


 

At J. Lauritzen, energy-efficiency is a top management focus as we consider it key to both business success and environmental responsibility. Not only does energy efficiency benefit the environment, it also leads to lower costs and improved competitiveness.

In our work to align our environmental efforts throughout the Group, several initiatives have been started to help us operate more efficiently and to help us comply with the environmental principles of the UN Global Compact.

Energy-Efficiency Project

In 2011, we initiated a joint Group project with the objective of enhancing fuel-efficiency and reducing emissions throughout our fleet. The Energy-Efficiency Project involves both bulk and gas carriers with the aim of identifying extensive solutions for more energy-efficient operations.

Our goal for the first two years was to reduce fuel consumption and cut emissions with up 10% whilst also achieving significant cost-savings. In 2013, we found that we had reached beyond this goal. 

The project focus on main and auxiliary engines, fuel and bunker management, energy consumption and voyage planning.

In March 2013, J. Lauritzen’s Executive Committee decided to strengthen the Energy Efficiency Project with a formal steering committee. The steering committee includes the presidents of each of J. Lauritzen’s business units and is headed by the CEO.

The efforts put into the Energy-Efficiency Project and the way new ideas are applied vary in the business unit. This is mainly because Lauritzen Kosan operates all functions from ship manning to technical operations, whereas Lauritzen Bulkers have outsourced technical management to specialised service providers, which makes a difference in how energy-efficiency initiatives are applied. The efforts put in by Lauritzen Bulkers are expressed through the business unit's Vessel Energy Renovation Plans, whereas Lauritzen Kosan's efforts are manifested in the REJUICE project.

Vessel Energy Renovation Plans

Lauritzen Bulkers’ Vessel Energy Renovation Plans (VERP) is a fleet performance catalogue that covers optimisation of auxiliary machine consumption, including pumps, fans and air conditioning, plus additional initiatives for technical and operational optimisation.

The ambition behind the VERP is to increase awareness of the importance of saving fuel, both in an economic and environmental perspective, and to improve knowledge of high tech solutions in our fleet of bulk carriers.

A VERP is always ship specific, and the potential savings vary from ship to ship. So far, the VERP has been implemented on seven vessels realising fuel-savings of approximately 7%.

REJUICE

Lauritzen Kosan's REJUICE project is an initiative with the objective to optimise energy-efficiency by cutting fuel consumption, for the benefit of our customers and the environment.

The project was launched in 2012, after a study showed that a significant reduction in emissions could be achieved through an improvement of current operational practices, such as trim and ballast conditions, hull cleaning, improved management of power consumptions and optimised fleet utilisation. Thus the REJUICE project includes energy-efficiency initiatives in several areas:

  • Voyage performance
  • Ship performance
  • Fuel management
  • Main and auxiliary engine
  • Energy consumption
  • Organisation and management

Through the installation of energy-saving equipment on our vessels, along with improved energy usage, we are able to save up to 10% of total fuel consumption and we have achieved proportional reductions for emissions to the environment.

ECOPRODIGI

ECOPRODIGI is a 3-year project funded by the Interreg Baltic Sea Region Programme which will conclude in 2020. Its goal is to bring eco-efficiency and digitalisation to the maritime industry. 

J. Lauritzen is participating in the “Vessel Performance Monitoring” element of the ECOPRODIGI project. This element has three main focus areas:

1.    The utilisation of AIS (automatic identification system) and hindcast data for the improved analysis of vessel performance
2.    Implementation of machine learning to prevent engine breakdown
3.    Developing tools to assist onboard personnel in energy efficient operations
