The Low-Down on Ultra-Low-Sulfur Diesel Boat Fuel

The Low-Down on Ultra-Low-Sulfur Diesel Boat Fuel - Anything to Worry About?

http://www.boatus.com/seaworthy/magazine/SeaOct11_UltraLowSulfurDiesel.pdf

ALEXANDRIA, Va., November 17, 2011 - As a way to reduce particulate matter, ultra-low-sulfur diesel (ULSD), with only 15 ppm or less of sulfur, was mandated for use in most vehicles, boats and machinery as of December 2010. As a practical matter, however, ULSD has been around since late 2006 when 2007 model year vehicles with more advanced emissions control devices began requiring its use in cars. And since most fuel refiners don't have the capacity to offer more than one type of diesel, it's also been sold at marinas ever since.


During that time, the BoatUS Damage Avoidance Program has kept a close look out for any potential problems with the newer, environmentally-friendly fuel. Recently, the boat owner association's Damage Avoidance Program publication, Seaworthy, The BoatUS Marine Insurance and Damage Avoidance Report, investigated the issue and has these findings to share:

Lubricity: In diesel engines, having enough "lubricity" in the fuel is critical - without it, the engine would grind itself to a premature death. A lot of publicity has been given to ULSD because the process of removing sulfur from diesel fuel also removes much of the fuel's lubricity. Contrary to what some have said, however, lubricity is not a problem with ULSD. Minimum lubricity is a requirement of the ASTM-D975 diesel fuel standard and oil companies typically use a synthetic additive to return fuel to its pre-ULSD lubricity levels.  

Cetane: All diesel fuel must have a cetane rating of at least 40. Most regular diesel fuel has a cetane rating of 43 to 45, which should be fine for most boat engines.  The good news is that the cetane numbers remained the same with ULSD.

Gaskets: When the transition was made to low-sulfur diesel (LSD) in 1993, there were problems with leaking gaskets. Newer gaskets that resist leaking were developed, but there were some fears that the gaskets might not stand up to ULSD. After talking to numerous marina owners and engine manufacturers, leaking gaskets don't appear to be a problem.

Water and "Bugs": Microbial growth - bugs - need water to grow and have always been a concern with diesel fuel. ULSD holds less water than older, higher-sulfur fuels, which means that any water entering the tank is less likely to be absorbed and instead more likely to become a breeding ground for bugs. Biocides (and cold weather) kill the bugs but their tiny little carcasses pile up in funereal goo at the bottom of the tank. Tanks may need to be cleaned more often to prevent clogged filters and corrosion. The best defense is to keep tanks as full as possible (especially over winter storage) and keep a routine eye on the water separator.

Fuel Polishing - Diesel Fuel Service Cart

Tammy Anstett - Monday, May 09, 2011
The Diesel Fuel Service Cart (DFS Cart) from Reverso Pumps, Inc. is the first portable 3-in-1 fuel polishing system on the market that is lightweight, streamlined and designed to meet exacting industry standards for safety and efficiency. The compact DFS Cart can be maneuvered and operated by one person and wheels easily up to a vessel, tank or equipment. It also can easily go up-and-down stairs due to the built-in skids.

The DFS Cart utilizes the world-class 5-stage Separ Filter fuel/water filtration system that removes water and 99.9% of particulate from diesel fuel. Unlike competitor carts, the Reverso Pumps DFS Cart has numerous safety and environmental features including maintenance alarms, clogged filter alarms, a drip pan for spillage, shut-off valves and water level shutdown features.

The DFS Cart not only polishes stored fuel in underground and above-ground storage tanks, but also cleans the fuel when dispensing into equipment or polishes the fuel already in tanks.

Fuel Polishing question - Effective Fuel Management - You Need a Plan

Tammy Anstett - Wednesday, May 04, 2011
Storage of diesel is often an overlooked area – a popular misconception is that diesel fuel is “good for life”.
The reality is very different.

To fully understand the issues at play, it is worth taking into account several areas:
• The Diesel fuel quality standard
• The specification of supplied diesel
• Known issues
• Recommendations from the fuel supplier
• Discovering issues before they become problems
• Short and long term solutions

To look at these issues, we have been in conversation with BP and have utilised their available library of fuel data.

Canada Requires Two Percent Renewable Diesel Fuel

Tammy Anstett - Tuesday, March 08, 2011
OTTAWA, Ontario, Canada, February 14, 2011 (ENS) - The Canadian government has set a start date of July 1, 2011 for requiring an average of two percent renewable diesel in all diesel fuel sold in Canada.

Renewable diesel is defined as a diesel fuel substitute made from renewable materials such as vegetable oil, waste cooking oil, animal fat, fish oil or cellulosic feedstocks consisting of agriculture and forest biomass. Biodiesel is one common example of a renewable diesel.

"When we announced our Renewable Fuels Strategy, we were clear that the two percent requirement would be implemented subject to technical feasibility," said Environment Minister Peter Kent, announcing the new policy on Thursday. "After positive results, we are moving forward with this requirement which will result in further reductions in greenhouse gas emissions and ultimately in cleaner air for all Canadians."

Diesel Free from Biofuels

UK. MDL Marinas becomes first marina operator to respond to widespread diesel legislation concern


Monday, 17 January 2011


MDL Marinas, Europe’s largest marina operator, has become the first UK marina group to offer diesel free from biofuels at its marina fuel stations. The move comes in response to growing concerns of boat owners, and sees MDL Marinas lead the way in the industry to become the first marina operator to meet the new British standard in this way.

A growing number of boaters have expressed concern over the increased risk of diesel bug due to the introduction of new fuel legislation. Diesel bug is feared because it can contaminate fuel tanks - quickly clogging filters and causing loss of power and engine breakdown. MDL has been working to secure the new diesel and is now offering low-sulphur fuel which is free from all biofuels (FAME-free), in accordance with the new British standard BS 2869:2010 – Class A2.

Dean Smith, Marketing Director at MDL Marinas, said: “We understand our customers concerns over biodiesel content in marine fuel, and through the support of our supplier, we are delighted to be able to secure supplies of diesel which meet the new British standard.
“To ensure this fuel reaches the pump in top condition, we conduct regular fuel tank cleaning and testing. This supply and our steps to ensure we maintain our fuel quality, gives our customers all the environmental benefits of low sulphur fuel with the added peace of mind that the potential problems of biodiesel will be avoided.”
