Tips & Procedures for day-to-day operation of your Cummins Onan Marine Generator

Here are some good general tips. You’ll find other helpful information in your Operator’s Manual which can be supplied by Cullys (just contact our office!)

  • Inspect and clear sea water strainers of debris, do not wait under they clog. Lack of inspection could result in seawater pump impeller damage
  • Inspect area around generator set to be sure nothing has moved or been knocked loose (rags, cleaning equipment, tools, spare parts, etc.) while underway, that could block air inlet or outlet or damage wires or hoses
  • Inspect generator est for fluid levels, leaks, and required service intervals based on operation hours and perform any identified maintenance as necessary

Ship Wastewater Discharge Performance Needs Enforcement, says ACO Marine

ACO Marine, together with a group of leading wastewater treatment system manufacturers and environmental organisations, has called for a revision to MARPOL Annex IV in order to verify the ongoing performance and discharge criteria of sewage treated systems onboard ship.

While there are rules in place for verifying discharge parameters, these relate only to type-approval testing in land-based establishments. There is currently no enforcement of the wastewater discharge criteria once a system has been installed and becomes operational onboard ship.

ACO Marine Managing Director Mark Beavis said: “The main contention is that we believe there are type-approved systems in operation at sea that are scientifically incapable of treating sewage waste.”

A paper co-authored by Beavis – Sewage Treatment with No-Sludge Production – A False Claim, and a Non-Conformity – attests: “Some manufacturers claim their sewage treatment plants do not produce sludge. Unfortunately, conformity assessment bodies have approved their equipment. But they have certified impossibilities and created certified ‘magic boxes’. These systems contravene science.”

Beavis said: “Sewage treatment plants protect the marine environment by turning raw sewage into less harmful effluent that meets specific discharge criteria set by the International Maritime Organisation. As a by-product of the treatment process sewage sludge is created that has to be either treated onboard or incinerated ashore. This sludge is a by-product or all treatment processes. But instead of being separated from the treatment process, this sludge is being flushed out in the effluent.

“These ‘magic boxes’ would not be able to perform no matter how well they are operated and we are very concerned about the environmental damage these systems are causing.”

While the rules were tightened with MEPC.227(64) and the use of dilution water limited during performance tests, this has not prevented the certification of these so-called sludge-free systems.

“Certificates have become licenses to pollute. Something is very wrong,” the authors state in the paper.

Existing Guidelines do not explicitly prohibit no-sludge systems but the authors believe the type approval regime is a “contradiction to the IMO’s intentions”. 

“There is a lot at stake: the credibility of the approval regimes, the liabilities to shipowners and yards, a level playing field, the IMO’s environmental aspirations and ultimately, the pristine marine water that we have agreed to protect,” say the authors.

The paper was co-authored by Mark Beavis, Managing Director, ACO Marine; Dr Wei Chen, Future Program Development Manager, Wartsila Water Systems Ltd, UK; Dr Elmar Dorgeloh, Manager Director, Development and Assessment Institute in Waste Water Technology at RWTH-Aachen University (PIA), Germany; Holger Hamann, Managing Director, Holger Hamann Consulting; Matthew MacGregor, Executive Director, TEi-Testing Services; Dr Daniel Todt, Project Manager R&D, Ecomotive AS; Niclas Karlsson, Managing Director, Clean Ship Scandinavia; Mark Mellinger, President, Headhunter Inc; and Felix von Bredow, Board of Hamman AG.

The authors call for IMO, its Member States and the approval assessment bodies to identify and to acknowledge the issue and establish protocols in order to prevent such non-conformities from reoccurring.

Prevent Fuel Varnishing

If you don’t run a tank of petrol each month, you could be risking the performance of your Cummins Onan RV Generator

If you store your RV over the winter, or don’t operate it often enough to refuel the petrol tank every month, you could develop a fuel varnishing problem in your generator engine.

Fuel varnishing is a gummy residue that clogs the generator carburettor and fuel pump. It’s caused by the deterioration of fuel that sits in the engine too long, and it happens in a surprisingly short period of time. Depending on fuel quality and storage conditions, gasoline can deteriorate in as little as 30 days. As long as you refuel frequently with fresh gasoline, and exercise the unit regularly, fuel varnishing is less likely to occur. But if you leave the same gasoline in the tank for several months, you’re very likely to have problems.

Fuel varnishing affects many engines but it’s more noticeable in generators because the engines are smaller. Even the slightest decrease in efficiency has a big impact on performance. A generator with varnish buildup may start but run like it needs a tune-up. It surges, accelerating and decelerating, but rarely settles at a stable operating speed. In many of the gasoline powered units, engine speed directly affects generator voltage output and frequency. As speed increases/decreases, so does the voltage and frequency.

The only ways to prevent fuel varnishing are to treat the contents of the tank supplying fuel to the generator with a fuel preservative and to exercise the set. Many quality fuel preservative and stabilisers are available. We recommend adding this preservative to the petrol, especially on infrequently used RVs.

Emptying the tank won’t prevent fuel varnishing because a small amount of fuel always remains in the generator carburettor. If you plan to leave the tank empty, we recommend that you add a special mixture of fuel and a preservative before you run the tank dry so the residual fuel contains the preservative.

Once varnishing has occurred, adding a preservative won’t correct the problem. You need to add a fuel cleaner, and manually scrub the varnish from the fuel system parts.

By understanding how to properly care for your RV generator and protect against fuel varnishing, you’ll enjoy better performance and longer operation. It may seem strange that “not” using a product causes it to fail faster. With generators, though, that’s exactly the case.

Important: Problems caused by fuel varnishing will not be covered under warranty.

SLCE Watermakers / Newsletter

Cruise Project

SLCE watermakers has just completed the 2nd sea trials of the first ship from the EDGE series, manufactured at Chantiers de l’Atlantique and designed for the shipowner Celebrity Cruises. Two units, each producing, 1 100 tpd of water with a salinity of less than 50 ppm are installed. These units from the XLE range benefit from an energy recovery system.

Mining Project

SLCE watermakers, through its representative in Chile ARSEPUR, received an order from BECHTEL, the engineering company in charge of Quebrada Blanca II project for TECK. SLCE watermakers will deliver, early 2019, two 40-footer producing each 1 160 tpd of freshwater. A third one will be delivered late 2019. The designed is based on the very heavy-duty range GBW60. The installation will operate at 4380 m above mean sea level in harsh environment.

Navy Project

NAVAL GROUP renewed its confidence in SLCE watermakers by entrusting the design and supply of the reverse-osmsosis watermakers for the future frigates FTI. Each unit, based on the SD22 design, will produce 32 m3/24h of freshwater. SLCE watermakers will also supply the hydrophores and the post-treatment subsets including post chlorination and hardness adjustment of the produced water.

Hotel in Saint Barthelemy

Following the hurricane IRMA that ravaged the island of Saint Barthelemy last year, the reverse-osmosis unit of the hotel “Le Barthélémy” was out of order and irreparable. Located in the basement, the installation of a new skid-mounted unit was impossible. SLCE watermakers has therefore delivered a unit in modules to be assembled on the spot on the old chassis. Since mid-June, the hotel has a new SH31-806 unit producing 90 m3/24h of freshwater.

Bahamas Island

BOUYGUES CONSTRUCTION recently ordered a container including an ultrafiltration pre-treatment followed by a reverse-osmosis process, producing 500 tpd of freshwater. The equipment will benefit from an energy recovery system. The unit will be located on the Exclusive Bahamian Marine Reserve Island dedicated to MSC Caribbean cruise guests. After producing the water during the construction phase, the unit will produce the freshwater to the guests.
