Environment

Since 2008, Solvang ASA  has collected, systematised and analysed data for consumption of natural resources, sailed distances, cargoes carried, and other information. The tool for collection and analysis were developed in-house and fine-tuned in accordance with our experiences. The collection and measurement of operational data was started in preparation for ISO 14001 (environmental standard) certification, which was achieved in 2010.

We suspected the potential to preserve natural resources within our operations. After some months of collecting data, we were able to identify the extent to which our environmental footprint could be lessened, and start measures to reduce consumption. A systematic approach, the presentation of results and valuable contributions from our seafarers have made this project a success.

The graph to the left shows the development of energy efficiency and NOX-emission for different age groups of LPG tankers with cargo capacity of 60,000 cbm. The graph to the right shows the development of specific cylinder oil consumption (g/kWh) over a five years period.

Below is our KPI matrix for environment. It displays consumption and emissions for 2012-2018, and targets for 2019.
