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.

Keeping Genset Fuel Flowing During Disasters
Developing A Strategy To Ensure The Availability Of Fuel For Your Generator System Is A Key Element Of Disaster Planning.

By Robert M. Menuet, PE, GHT Limited, Arlington, Va.
06/01/2011

Originally published at: Consulting-Specifying Engineer

Mr. Menuet states that as part of your disaster plans you should "consider installing a fuel filtering or polishing system that will remove moisture and help prevent fuel degradation. Sediment that can build up in the bottom of storage tanks can be stirred up when fuel is delivered, often resulting in clogged filters and injectors, or decreased engine performance.

Fuel polishing and filtration helps minimize this buildup. Also consider fuel additives that will prolong fuel life, suspend contaminants so they can be trapped by the system filters, protect against corrosion, and prevent biological growths."

Our commercial, government, and institutional operations depend on the continuous availability of electrical power to run critical equipment. Prolonged, large-scale power outages, though rare, have significant financial and service delivery impacts. You need to be ready when disaster strikes.

Disasters vary in type and severity. Fuel supply planning for local severe weather events and regional blackouts is vastly different from the strategies required to defend against an unforeseeable terrorist attack or an extraordinary natural catastrophe such as Hurricane Katrina. The considerations outlined in this article are intended to guide you through the planning process to defend against reasonably predictable disasters.

Diesel vs. natural gas

Diesel-fueled generators are better suited for larger power requirements than natural gas-powered generators, yet require more physical space and maintenance to sustain a reliable fuel source. Building owners typically select natural gas generators when they require a lower initial capital investment and prefer not to maintain an on-site fuel supply.

Because natural gas is supplied by the local utility and delivered underground, the primary factor that building owners can control in relation to disaster defense is the purchase of non-interruptible service. Your utility will typically charge a slightly higher rate in exchange for a guarantee of fuel availability during a local disaster event, but many owners find this preferable to managing a diesel fuel supply for their generator.

When choosing between natural gas and diesel, it is important to note that natural gas generators may not satisfy local life safety requirements. If the utility source is not deemed reliable for emergency operations by the local authority, diesel engine generators are generally the only practical alternative.

For buildings that shelter critical business functions or have other high availability requirements, the decision to use an on-site diesel-powered generator is often made as part of overall disaster planning. Once this choice is made, there are numerous factors that can influence the configuration of the fuel supply. Considerations that can make this process more manageable include:

  • Fuel quantity
  • Refueling availability
  • Storage and compartmentation
  • Fuel quality
  • Safety and security

Fuel quantity

Identifying the amount of fuel needed to power your critical equipment during a reasonably predictable natural catastrophe is the first step. A rough consumption calculation for diesel generators is 7 gallons of fuel per hour for each 100 kW of generator rating; i.e., a 200 kW generator would consume 14 gallons of diesel fuel per hour. A typical goal for on-site storage is three days’ worth of fuel. A site requiring a 2 MW generator installation should have approximately 10,000 gallons of available stored fuel to provide a three-day supply. To ensure the necessary amount is on hand in the event of a disaster, you should factor engine exercising into your equation, and understand that refilling a partially depleted storage tank may not be practical until sufficient fuel is depleted to justify a fuel delivery. Purchase a storage system that will accommodate your disaster-threshold fuel plus the amount you will consume for engine testing as part of regular maintenance.

When determining the amount of fuel to store on-site, you must consider the criticality of your location and the nature of your operation at the site. If your facility provides critical functions required for your business that are not duplicated in another location, a larger quantity of fuel should be considered to ensure continued operations during an extended power outage. Consider the impact an extended utility outage would have on your organization’s bottom line. The data center of an online retailer would likely face far greater revenue losses during an extended power outage than the administrative office of a sales force that telecommutes and travels on a regular basis. Storing fuel can be expensive, so a business case should be developed that considers capital expenses and risk factors. Weigh the installation costs and maintenance requirements of storing fuel against the financial impacts of downtime—including the direct costs of lost revenue, recovery of operations, and the potential loss of customers.

According to the American Red Cross, “As many as 40% of small businesses do not reopen after a major disaster like a flood, tornado, or earthquake. These shuttered businesses were unprepared for a disaster; they had no plan or backup systems.”

Refueling availability

Refueling availability will impact your decision on how much fuel to store on-site. Is it financially and logistically feasible to store all or some of the desired amount in your building or on your property? Can you arrange to have a supplier outside of the region bring fuel when needed? In the second scenario, the fuel supplier down the street may be affected by the same natural disaster, so arranging delivery assurances from several geographically disparate suppliers may make sense. Selecting remote suppliers that use different transportation routes can further ensure refueling availability when a disaster has a widespread impact. Typically it is not practical—logistically or economically—to store more than several days’ supply on-site, so a balance between on-site storage and delivery assurances from suppliers should position you to survive an extended loss of electrical power.

Storage and Compartmentation

On-Site Storage—For the fuel you store on-site, the first consideration is conforming to local and state codes, Environmental Protection Agency (EPA) regulations, and National Fire Protection Association guidelines. Codes are intended to safeguard buildings and their occupants, while EPA is primarily concerned with the environmental impact of spills. Sustainable design certifications that encompass building energy usage, such as the U.S. Green Building Council LEED program, may also influence how much and where the fuel is stored.

The amount of on-site fuel storage will likely dictate storage locations and configurations. Large amounts of fuel are typically stored outside the building, either in above- or below-ground tanks. Below-grade storage requires EPA compliance for leak monitoring, and may necessitate groundwater monitoring and other spill detection methods. Local and state codes may have additional requirements for outdoor storage solutions.

For outdoor generators, engineers often specify that the fuel be stored in belly tanks under the generator. This can be a convenient, space-saving option, though there is a practical limit to the amount of fuel a belly tank can hold. If a tank is too large, stairs, platforms, or ladders may be required to gain access to service the generator. If a belly tank is too small, your operating time will be limited if it is your only method of storage. Discuss these considerations with your operations and maintenance staff.

In-building storage may be the best solution for smaller amounts of stored fuel. It also offers better protection from temperature fluctuations, weather events, and tampering. An example from Hurricane Katrina illustrates this point. As noted in “FAILURE OF INITIATIVE: Final Report of the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina,” “Many of the parish EOCs [Emergency Operations Centers] and public safety facilities were wiped out or flooded. Jefferson Parish…was in better shape to respond because it had protected its EOC. Jefferson Parish Emergency Manager Dr. Walter Maestri explained the EOC was in a hardened facility—an old incinerator with cement walls—with the command center, living quarters, and emergency generator all on upper floors...[and] it was able to keep operating at some level.”

Fuel stored within your facility will require compliance with building codes, local and state codes, and building insurance requirements. Building and structure insurance policies often have strict requirements for the type and amount of fuel and storage equipment.

Compartmentation—While compliance with building codes and other mandatory requirements will result in a safe installation, there are other choices a user can make to improve the availability of the stored fuel. Compartmentation can help safeguard some or all of your reserve if a single localized event occurs, such as an explosion or fire. With compartmentation, the total amount of fuel is divided among multiple tanks. Fire- and blast-resistant separating-structures ensure there are barriers between tanks to prevent a local event from affecting the entire supply.

Compartmentation also supports the availability of backup fuel if one tank develops quality problems. Also, the use of multiple storage vessels helps limit cross-contamination should one tank be replenished with contaminated fuel.

Fuel quality

If you store fuel on-site, consider installing a fuel filtering or polishing system that will remove moisture and help prevent fuel degradation. Sediment that can build up in the bottom of storage tanks can be stirred up when fuel is delivered, often resulting in clogged filters and injectors, or decreased engine performance.

Fuel polishing and filtration helps minimize this buildup. Also consider fuel additives that will prolong fuel life, suspend contaminants so they can be trapped by the system filters, protect against corrosion, and prevent biological growths.

Temperature Considerations—Atmospheric temperatures can affect fuel quality. At approximately 30 F, fuel begins to cloud as the paraffin in the fuel starts to solidify. At 15 F, this solidification can turn into wax and can be severe enough to clog filters in the system.

Most providers offer winter blends designed to minimize clouding. If financial or logistical reasons necessitate the use of a summer blend fuel as you enter colder weather, other strategies to prevent this problem include additives, heat trace of piping, and immersion tank heaters.

Safety and security

Ensuring the safety of building occupants and the security of your fuel supply is fairly straightforward. During facility design, provide a rated room for fuel and generators stored in the building. Locate it near a loading dock or other low-traffic area, and provide controlled access. When using outdoor storage, critical facilities will likely have perimeter security in place to safeguard their fuel supply and generators. For less intensive facilities, secure walls or fencing around the fuel storage tanks is the most common protection strategy.

Planning ahead

It is impossible to predict every disaster scenario that could impact your fuel supply. But with early, careful planning, you can determine the amount, availability, storage, protection, and quality of a fuel supply that can support your operations through many of the most common natural catastrophes that occur in your region. A balanced strategy that considers costs and risks will ensure the success of your plan.

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.

Now that's Clean Fuel! Fuel Polishing Works Wonders

Tammy Anstett - Tuesday, May 03, 2011
Amazing difference!
Fuel Polishing for the TRINIDAD AND TOBAGO COAST GUARD 

This is an extreme case as the fuel sat unused in contaminated tanks for nearly two years. A Reverso 600 GPH was used to complete the polishing. The FPS 210 can perform equally well and the FPS 150 is good for smaller tanks and the FPS 80 for very small tanks.

Fuel Polishing question - Fuel Replacement

Tammy Anstett - Wednesday, April 27, 2011
Q: We have a number of diesel fuel tanks for backup generators.  We normally replace our fuel once per year and use very little during the course of a normal year. Our tanks are inside and never exposed to very high or very low temperatures. Does fuel polishing improve this replacement time? By how much? 

A: Yes, fuel polishing systems when installed correctly will prevent the accumulation of water in the bottom of the tank and extend the life of your fuel thereby reducing your replacement time.

Water at the bottom of the tank allows bacteria, mold and other biological organisms to live in the tank, feed on the fuel and create sludge. In addition, fuel oxidizes over time which creates the dark brown color that you see. This too can all be filtered out with a polisher.

(The use of additives such as ILFC Ten-35 should be added to the tank every time you fuel or every six (6) months. This will cause all water in the tank to coalesce and drop to the bottom as Free Water where the polishing system can remove it before bacteria starts to grow. ILFC is also a stabilizer and Cetane enhancer.)

You can easily extend the life of the fuel beyond two (2) years and in some cases three (3) years with fuel polishing. The ROI on a large fuel polisher would be one (1) year or less. 

Cetane Numbers and Your Engine

Tammy Anstett - Wednesday, September 22, 2010
We are now offering the ILFC Ten 35 Fuel Additive in our store. ILFC TEN 35 gives you greater fuel efficiency and is designed to be completely soluble in fuel oils and can be added directly to fuel in storage. Ten 35 helps increase your cetane number and is core part of our Fuel Management Systems.

Why Do I Need To Worry About Cetane Numbers?

The longer diesel fuel is stored, the lower the cetane number. Even if the fuel quality is good (low particulate, sludge or water buildup) the fuel will not perform at the level necessary for the engine to run at optimal performance.

What is a Cetane Number?

The cetane number is to diesel fuel what the octane number is to gasoline. The higher the cetane number - the better the fuel will burn. It is the performance of diesel fuel’s combustion quality - not a measure of the fuel quality itself.  A higher cetane number indicates more energy is available to the engine. Therefore, you have greater fuel efficiency due to a shorter ignition delay time and more complete combustion of the fuel.

An appropriately high cetane number means improved cold starting, smoother running, less smoke at start-up, improved fuel efficiency, improved engine durability, fewer emissions, more power and reduced noise and vibration.

How Does the Cetane Number Affect Engine Performance?

Running a diesel engine on fuel with a lower than recommended cetane number can result in rough operation (noise and vibration), difficulty in starting – especially in cold temperatures, low power output, excessive sludge deposits, increased exhaust emissions and excessive wear.

The ASTN Standard Specification for Diesel Fuel Oils (D-975) states. "The cetane number requirements depend on engine design, size, nature of speed and load variations, and on starting and atmospheric conditions. Increase in cetane number over values actually required does not materially improve engine performance. Accordingly, the cetane number specified should be as low as possible to insure maximum fuel availability."

Thus you should match engine cetane requirements with your fuel cetane levels for optimal performance.
