MarineDiesel Services Profile: Engine Installation and Commissioning


Today’s article continues our series profiling MarineDiesel’s various services.

Engine Installation and Commissioning

MarineDiesel understands that when we sell an engine, we often need to be the ones who install and commission that engine. Most commercial shipyards are perfectly competent to install an engine, yet, particularly on new projects, factory installation is desirable. It is also important to note that all MarineDiesel distributors are fully trained in engine installation and can perform these services locally.

One of the most critical tasks related to the reliability of  the entire propulsion system is the installation of engine and drive system. This can be performed by the operator, boat builder or the local Marinediesel representative, but it can also be performed by Marinediesel factory engineers on site anywhere in the world.
MarineDiesel factory engineers provide first grade quality service,  as well as reducing  the risk of breakdowns and stoppages related to poor installation. It can also allow for time to train local technicians on installations, thus, for the future, enhancing the skill and know-how level of the operator’s or boat builder’s own staff.
A professional installation  not only assures smooth  operation, but it also reduces operational  costs. In this context, prolonging engine  life  and  maintaining  operational efficiency are key objectives that are addressed by this program.
Marinediesel  can also supply a full project management service, supported  by expert personnel  and by a global back-up service. All this is targeted at the goal of providing the operator with complete confidence that the engines will run efficiently with excellent long term service.
Quality based , cost effective service delivered by factory engineers
Opportunity for the transfer of technology and know how.
Operational costs minimized due to reduced risk of breakdowns and stoppages related to poor installation
Expert project management
Peace of mind with full OEM warranty

The  quality workmanship of the propulsion system installation is verifìed and signed off during the commissioning. Our  fìeld  service  engineers  are  uniquely experienced   in commissioning engines,  and  will ensure  that  every aspect of their  performance is fully tested  and  optimized before handover. This includes auxiliary equipment such as transmissions  and drive systems in liaising with other suppliers when necessary to ensure that every part of the installation functions correctly. Commissioning can be performed by Marinediesel fìeld service  engineers  on  site  anywhere  in the world. The  commissioning sign-off is also required  for warranty to take effect.



MarineDiesel Services Profile: Engineering



We at MarineDiesel often refer to ourself as an engineering company, rather than as a manufacturer. The reason we do so is that a substantial portion of our annual revenues come from engineering services, rather than engine sales.

As a diesel engine maker, we are required to invest in a substantial level of infrastructure that is highly specialized. This infrastructure is used to customize engines and design engines for specific purposes, which makes MarineDiesel ideally suited to offer complete engineering services to our customers, whether they use our engines or not. Indeed, we consider several of our competitors also to be customers, since we have completed many such projects for them. This is a primary selling point for MarineDiesel: We can usually accomplish things both quicker and cheaper than our much larger competition cannot.

These services include, but are not limited to:

  • Torsional vibration analysis
  • Flow simulation
  • Engine Testing
  • Emissions Testing
  • Compliance Testing (eg. NATO or Intrinsically Safe)

As long as our facilities allow it, in terms of size (We do not have the facilities to test two stroke, 2 mW engines, for example), we can offer customers complete turnkey engineering solutions. Our facilities are state-of-the-art, designed by GM. We have the latest test cells, software, and equipment.

MD ENGINEERING hosts three engine dynos in its test facility, with each test cell having its own unique measurement range and options. This provides us a great span in terms of engine size and application to better meet our client’s requirements and specifications. All cells are equipped with high frequency, multi-channel data logging.

MD Engineering has been involved in complete engine control systems in a multitude of areas, some areas where we have deep knowledge and long experience:

• Control safety systems
• Torque management and control
• Air system diagnostics (MAF, EGR, Swirl)
• EOBD and OBDII controls and diagnostics
• Engine thermal management control and diagnostics
• After treatment systems control and diagnostics
• Stop/start control
• Boost system control for a wide variety of hardware setups:
• Single wastgate turbo and by-pass turbo
• Two-stage turbocharging
• Supercharger
• Twin turbo
• VNT turbo

Our engineers and product analysis experts can take a wide client brief for comparative benchmark and cross product comparison. This includes all aspects of the process from virtual analysis, desktop studies, static and dynamic repeatable test scenarios to full product teardown, measurement reporting and recommendations.

MarineDiesel, through the normal course of business, maintains partnerships with numerous naval architects, engineering firms, automobile manufacturers, other engine manufacturers, and designers. In fact, we are often the ones providing the project management services on complex projects.

To illustrate, we recently were involved in a project where we provided the engines for a new boat, along with the design, and handled the entire contracting process with the shipyard.

MD Engineering is a division of MD Group that comprises of three divisions with fields ranging from engineering to powertrain supply and marine propulsion engines.

Financing Your Engines



Engines usually constitute a major percentage of the costs of any marine or industrial project. Indeed, on some high performance boat designs, the engines and drives can be as much as 30% or more of the total price.

By offering complete propulsion packages, engine, gearbox, and drive, MarineDiesel can often help offset some of these costs while guaranteeing performance levels.

However, formal financing is often a requirement for our customers, particularly on large projects.

Engine purchases are often very difficult to finance, due to the fact that it can be very difficult to separate an engine purchase from the purchase of the vessel. It comes down to risk: The finance company looks at the risk from the “what if the customer doesn’t pay?” perspective. This problem is compounded by the fact that engines depreciate up to 30% of their value on the date of commissioning, whether used beyond that date or not. Therefore, most engine manufacturers that offer financing are only able to make that offer when the engines are tied via lien to the financing of the vessel as a whole. This often causes conflicts with documentation or complications on the financing itself.

So, what is the solution?

MarineDiesel works with EKN, the Swedish government’s export finance department ( EKN Website ), to offer financing plans to our customers. The financing program requires approval, and is not available in every region or on every project, but we have financed numerous projects through them in the past, and the process is relatively straightforward.

Additionally, MarineDiesel works with other lenders in different regions, and we can occasionally make arrangements for specific projects. Simply inquire with us or your local distributor at the time of quotation and we will try and arrange a financing proposal for your project.




Some MarineDiesel Projects – Military Vessels



Today’s post continues the series of reference photos we have been posting this week. The photos below are of MarineDiesel projects related to military and government vessels.

Indeed, MarineDiesel’s specialization in high performance power is ideally suited to military vessels. Long life cycles and unmatched torque curves make MarineDiesel the best choice, and sometimes the only choice, for powering military vessels. Engines developed for recreational use simply cannot withstand the harsh operating conditions and power demands that military missions require.

If you have an upcoming project, contact us directly or your MarineDiesel distributor for a custom quote or proposal.




















MarineDiesel VGT + Konrad Performance Package



MarineDiesel has teamed up with Konrad to offer the most reliable engine and sterndrive high performance package in the marine market today.

Sterndrives have some distinct advantages as a propulsion system over other types of drive. They are capable of producing very high speeds and yet, can offer good maneuverability at slower speeds. Traditionally, the Achilles Heel of sterndrive systems has been their reliability and high cost of maintenance. They just could not stand up to the high torque produced by diesel engines and heavy, continuous use by commercial or government users.

Until Now…

Konrad is recognized as producing the only reliable sterndrive propulsion system that can withstand heavy commercial or military use.


The Konrad sterndrive can last over 2,500 hours between overhauls.

This makes the Konrad sterndrives the only real option available to commercial users. Drives produced for use with gasoline engines, or for intermittent recreational use generally require overhauls in as few as 400 hours. Though often inexpensive to purchase, they can quickly become extremely expensive to own over the long term. For commercial users, this adds up to many thousands of dollars of expenses over time.

The sheet below illustrates the cost advantages of Konrad over other brands of sterndrive.

When paired with MarineDiesel’s VGT Series of engines,

Please take a look and send us a note if you would like to have a custom quote on a package for your vessel.

Engine Ratings: Recreational vs. Commercial vs. Government



When purchasing a diesel engine for your vessel, often the first question that arises is, “what is the engine’s rating”?

Engines are manufactured with different ratings: The amount of power that the engine can produce over a period of time (hours) under a specific type of use. Every engine manufacturer offers engines designed for a specific purpose or use, often using the same block, but generally having different components between ratings. For instance, an engine may use a 5 liter displacement block, but come in several different models and ratings:

  • 400 hp @ 3,200 rpm for recreational use (Under ___ Hours per year)*Varies by manufacturer… there is no universal standard
  • 350 hp @ 3,200 rpm for light commercial duty (Under ___ Hours per year)
  • 320 hp @ 3,000 rpm for heavy commercial use (Over ___ Hours per year)
  • 400 hp @ 3,000 rpm for government use (Government use usually has wide variations in required power and hours of use)
  • 250 hp @ 1,800 rpm for continuous use (usually on gensets)


So, all of this means that the same engine might be rated to produce different power levels at different amounts of use under differing conditions.

MarineDiesel’s VGT Series is no exception. However, we rate our engines for heavy commercial or government use as standard, and derate the engines down at different power levels. By using ratings in this manner, our engines have a far higher reliability than the engines manufactured by our competitors. Indeed, two of our largest competitors ONLY rate their engines for recreational use, or with slight variations for commercial or government use.

What does this mean?

It means that their engines were designed to be used on recreational vessels (normally around 200 hours per year, maximum), but they are often used in excess of 2,000 hours per year annually on government or commercial vessels that usually operate under far harsher conditions.

MarineDiesel rates our engines on the assumption that they will be heavily used. Cables are shielded against RF. Metal connectors are used instead of plastic. Mounts and couplings assume heavy seas and vibration. ECUs are programmed to produce high, continuous torque. We assume dirty or bad fuel quality in remote locations. We assume a harsh climate. If a customer installs them on a recreational vessel, they simply get higher levels of reliability.

Heat disbursement is the biggest challenge we face. Higher horsepower under heavy use produces far more heat than the same horsepower under intermittent use. This heat needs to be dissipated. Therefore, though the engine block may be the same, the cooling system will likely be different, as will the turbocharger and fuel systems.
