In one of the most prestigious biofuel tests, bp and Maersk Tankers, with the support of the Danish Maritime Authority, have carried out tests using marine fuel mixed with biofuels in tankers. They said this demonstrates that sustainable biofuels can be used as a marine “alternative fuel” to help reduce carbon emissions in shipping.

The tests were carried out using two product tankers chartered on time from Maersk Tankers. The ships were the four years Maersk Cirrus, a 39,999 dwt tanker and the five-year-old child Maersk browser, a 45,999 dwt tanker. Each vessel was supplied with bp Marine B30 biofuel, which is 30 percent fatty acid methyl esters (FAME) mixed with ultra low sulfur fuel oil (VLSFO). According to bp, FAME is a renewable alternative biofuel produced largely from recycled cooking oils and renewable oil sources. It has physical properties similar to conventional diesel and is also non-toxic and biodegradable. The origin and production of the raw materials used to produce FAME are certified for their sustainability according to internationally recognized standards.

The tests saw the ships sail from Rotterdam to West Africa. Throughout the trials, tests were carried out to assess the reliability and performance of the B30 biofuel blend in the main engine, auxiliary engine and boiler of each vessel, as well as any impact on the fuel tanks to determine the level of interchangeability with other types of fuel.

They reported that they did not observe any adverse effects on equipment or machinery during or after the tests. No modifications to the engine or infrastructure were necessary, they said, demonstrating the suitability of sustainable biofuels for use as an “alternative fuel”.

bp works with companies in key industrial sectors that have significant carbon emissions to manage, supporting their decarbonization work. Based on the results of recent testing, bp aims to provide regular biofuel blends for their on-time operated and chartered vessels when refueling in the Netherlands, subject to owner and state approval. of the pavilion. This is part of his ongoing efforts to help decarbonize the shipping industry.

Maersk Tankers, for its part, indicates that it is developing and deploying solutions that help shipowners boost the economic and environmental performance of their vessels. Through its pools and industry-wide collaboration, the company works in partnership to contribute to a more sustainable future for the industry.
