Power Take Off

Marinediesel offers various PTO options with all of the engines we manufacture. In fact, the list of applications would be quite large, were we to list them all. Some examples of PTO options we have provided in the past, for both marine and industrial uses include:

  • Alternators
  • Pumps
  • Hydraulic Motors
  • Fire Control Systems
  • Blower Systems
  • Lifts, Davits, and Cranes

In fact, PTO is a standardized option, and a variety of shafts and couplings can be provided, depending on the use. You need merely ask your dealer or distributor to add it to your purchase and we will do the rest!

Arctic Trucks, Iceland

Short posting today. We were recently in Iceland meeting with Arctic Trucks. A very interesting application for Marinediesel engines. Iceland has both challenging terrain and a challenging environment for any engine. Outside of the capitol, Reykjavik, there are mostly gravel roads, rivers to be forded, and many areas unsuitable for standard passenger cars. Marinediesel allows customized power and torque that can easily meet these challenges.

Arctic Trucks has produced vehicles specifically designed to conquer the environment for over 25 years. Visit their website for more information about their unique products.

VGT: THE diesel alternative to outboards

Outboards are common on small, high speed craft. Indeed, on some vessel types, they are often though of as the “default” propulsion method.

Why?

  1. They are cheap.
  2. They are easy to maintain.
  3. They provide “pretty good” speed.
  4. They do not take up much space.
  5. They are lightweight.
  6. A row of them, side-by-side “looks” fast and impressive.

However, outboard engines have some serious disadvantages and limitations:

  1. Outboard engines are usually gasoline automobile engines that are mounted vertically to a gearbox and drive system as a single unit. The forces generated by these engines are vertical, rather than horizontal, resulting in a substantial loss of power and a drastic increase in wear.
  2. Gasoline (petrol) is an explosion and fire risk, especially with government vessels or those used in the offshore industry. (Diesel is a much safer fuel)
  3. Gasoline is usually more expensive than diesel. Additionally, gasoline engines always consume fuel at a higher rate than diesel engines. (In some markets, the differential is as much as 50%).
  4. Outboard engines have a life cycle that is usually no more than a few hundred hours, at best. (You can  easily replace an outboard five times before needing to rebuild a VGT engine… Not so cheap now, eh?)
  5. Outboard engines are, by their design, limited in the number of propulsion options (You get what you get. With a VGT engine, you can use jets, surface drives, a variety of stern drives, or traditional shafts.)
  6. Diesel engines provide far more torque than outboard engines (Outboards cannot even come close).
  7. The vessel will always perform better with a VGT engine and proper propulsion system. ALWAYS.

The Marinediesel VGT Series of engines was designed to be the lightest, most powerful engines in their class. Our compact size and high power output make them an ideal alternative to the use of outboard engines. The VGT will, quite simply, fit where other engines may not.

Vessels can be equipped with Marinediesel inboard VGT engines at only a slightly higher cost than equipping the same vessel with large outboard engines, and that slightly higher cost is recouped very quickly in a much longer service life and the substantial fuel savings received. In fact, on larger outboard vessels, the use of outboards for propulsion is often equated by simply flushing money down the drain. They always cost more in the long term. In fact, many of our customers refer to outboards as “throwaway” engines. They run them full throttle until they simply break, and replace them with a new engine.

sunk-cost

This “ease of replacement” and “ease of repair” is very much an illusion. The Marinediesel VGT Series will last up to five times longer than the average outboard before requiring an overhaul. Additionally, our remote mounting options give the VGT Series an ease of maintenance that approaches even the best designed outboard.

Additionally, the higher power and torque give a much better level of performance and control than an outboard-equipped vessel. Outboards, by design, are limited in the amount of operational control that they can provide, particularly regarding trim. A well-designed propulsion package with inboard engines will give a higher level of control and speed than even the best outboards on the market.

Finally, outboard engines are external, and thus, noisy by design. They are very difficult to control noise, and are often impossible for effective noise control.

If you want to look into the feasibility of using our VGT engines instead of outboards, and experiencing the meaning of true performance, Contact Us or your local Marinediesel Distributor for a quote today.

VGT Series Break-in Procedures

When engines are new, they require certain break-in, or run-in, procedures before they are subjected to heavy use. The reason is that, though the engines are tested at the factory, seals and gaskets need both heat and time to form a good seal, and the engine needs time to properly lubricate. If proper break-in procedures are not followed, severe engine damage can result.

Below is the procedures for our VGT Series of engines.

The Marinediesel VGT series engines need break-in time before being operating to its full potential. This is due to the design characteristics of the base engine.

Follow the recommendations below:

0-5hrs: Use varied load and rpm but do not load the engine above 50% throttle and keep maximum rpm below 2500. Do not stay at one load and rpm configuration for more than 30 minutes at a time.

5-10hrs: Use varied load and rpm but do not load the engine above 60% throttle and keep maximum rpm below 2800. Do not stay at one load and rpm configuration for more than 30 minutes at a time. A few short WOT trials up to 3600 rpm is allowed for performance trials

Do an oil and filter change after the engine has run a total of 10hrs.

10-30hrs: Use varied load and rpm, the engine can be used up to 100% throttle and full rpm for shorter periods. Do not stay at one load and rpm configuration for more than 30 minutes at a time.

Do an oil and filter change after the engine has run a total of 50hrs.
Use oil and filter as specified in the engine technical manual.

If you have any questions regarding this break-in procedure please consult the technical department at Marinediesel in Sweden.

 

 

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

COMMISSIONING
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.
