The retrofit concept

MAN Diesel’s retrofit concept consists of a broad range of

solutions where its PrimeServ af ter-sales division applies

the latest developments within diesel technology to

engines in service, in the process bringing them up to cur-

rent standards and meeting modern emission levels and

lowering running costs.

The concept applies to all MAN Diesel engines (both

marine and stationary), propellers and turbochargers. It

can even be applied to engines from other manufacturersand has multiple benefits for engines, vessels and

shipowners alike:

• Improved engine performance

• Engines in service updated to modern standards

• Lower fuel and lube-oil consumption leading to lower

operating costs

• Longer time between overhauls

• Emissions reduction

• Life-cycle extension

• Monitoring and controlling equipment to facilitate

operations

• Major fuel conversions where requested

Emissions reduction

MAN Diesel regularly introduces design innovations in the

field of emissions reduction, while the IMO’s Tier-II and Tier-III

emission regulations also exert a great influence on modern

engine technology. MAN Diesel’s engine portfolio recently

became fully Tier-II compliant, and older two- and four-stroke

engine generations can easily be made compliant through

a variety of retrofit techniques like the installation of slide

fuel-valves and start-limiters. The retrofit concept also covers

more comprehensive installations such as the NOx-reducingWIF (Water In Fuel)/FWE (Fuel Water Emulsification) system.

Monitoring and controlling equipment

Diesel technology becomes more advanced with every year

but MAN Diesel engines can be upgraded to reap the benefit

of the new technology. This includes advances in monitoring

and controlling systems that improve safety and optimise your

engines performance. These include the PMI (cylinder-pres-

sure analyser) system and bearing-wear monitor.

Life-cycle extension/reliability improvement

Apart from techniques designed to upgrade your engine’s

performance, MAN Diesel PrimeServ can also enhance life-

times and general reliability, extending the useful life of your

engines through the retrofitting of anti-corrosion valves and

coated nozzle rings, to mention just a few possibilities. More

comprehensive retrofit options such as engine up-rating are

also available.

Fuel and lube oil-saving packages

The consumption of fuel- and lubricating-oil is one of the big-

gest expenses in modern shipping. PrimeServ can minimise

your engines’ oil use and maximise the return on your invest-

ment through the retrofitting of cutting-edge technology de-

signed to make your vessel ever more efficient. This includes

such retrofits as the Alpha Lubricator, stepped liners/pistons,

turbocharger retrofit with VTA technology, and tailor-made

slow steaming on request.

Major fuel conversions

As the price and availability of fuel varies, it can become

more economical to change the fuel that powers your prime

mover, or at least to have the option of switching between

fuel types. Fuel conversion is a large undertaking but one in

which MAN Diesel PrimeServ has long experience, including:

• Heavy Fuel Oil to Dual Fuel – MAN Diesel four-stroke

48/60 and 32/40 engines and PC-engines

• Gas conversion

• Heavy Fuel Oil retrofit-kit (common-rail retrofit)

MAN Diesel PrimeServ provides original spare-parts andservice facilities for MAN Diesel’s two- and four-stroke diesel

engines, generating sets, turbochargers, CP propellers and

complete propulsion packages. To support this, it operates a

worldwide, round-the-clock service, 365 days a year through

a network of service headquarters and service centres.
