Diagomar Plus is a proof of Lubmarine's commitment to meeting the exacting safety and performance
demands of today's shipowner. This advanced easy-to-use system is backed by the high standard of
service and quality that customers have come to expect from a leading name is marine lubricant technology.
Diagomar Plus is an essential cost-saving tool which allows shipowners to minimise equipment breakdown
and to maximise oil life.

Diagomar Plus was developed by Lubmarine in co-operation with Intertek Caleb Brett, which is recognised as a
world leader in the inspection and testing of lube oils, fuels, petroleum products and chemicals.
> As a service, Diagomar Plus offers:

High speed: fast on-the-spot analyses of lubricant samples with rapid delivery of results,
High efficiency: automatic transfer and storage of test results to a full historical database
available for consultation by customer via the internet,
High reliability: the latest technology and state-of-the-art measuring equipment,
More user-friendly operation: Diagomar Plus is designed for extreme simplicity of use,
Three strategically located laboratories: Rotterdam, Singapore and Columbus,
The added value of a technical expert to make diagnosis of and comment on each analysis.

SAMPLING KITS

Sampling kits complete with a set of 18-bottles are available for sample preparation.
Each kit contains a leaflet with full instructions for drawing and dispatching samples,
vessels can choose the analysis laboratory nearest to their current stop-off port.
If extra kits are required, a request can be made on the oil sample label, and dealt with immediately.

A COMPLETE RANGE OF ANALYSES

Viscosity

Viscosity is a measure of the ability of the lubricant to flow. Diagomar Plus provides an
automatic viscosimeter indicating viscosity at 40°C and 100°C. The viscosity of a lubricant
cannot be used in isolation to assess lubricant condition. However, it provides very useful
information when used in conjunction with other determining factors such as the level of
oxidation or contamination by fuel, water or other elements.

Insoluble Products

In service, the lubricant in an engine is contaminated by a number of insoluble products.
Monitoring their presence provides a very good indication of the operating condition of the
engine or the effectiveness of the purifier or the filters. It also safeguards against breakdowns
since a sudden increase in the presence of insoluble products indicates a malfunction.

Flash Point

The flash point is the temperature at which the application of a flame will ignite the vapours
produced by an oil sample heated under standard conditions. Below a certain value there is a
high risk of very serious incidents in service including crankcase explosion.
Flash Point must therefore be monitored very carefully.

Water Content

Water, even in small quantities, is always unwelcome in a lubricant because it can act as a
contaminant. A check of the water content will indicate any defect in the engine, the
auxiliary equipment, or -if one is fitted- in the purifier. Where water is present, testing determines
whether it is fresh or sea water.

BN or Alkalinity Reserve

During the combustion process the sulphur contained in the fuel produces acidic products
that can damage the engine. This acid must be neutralised to avoid extensive corrosive wear
of the liner or rings. This important function is performed by specific additives in the lubricant,
the amount and type of which are measured by the BN (Base Number) which represents the alkalinity reserve.
Close monitoring of the BN in service is essential to ensure that the lubricant still has sufficient
alkalinity reserve to perform correctly.

Wear Metal Elements

Monitoring changes in metal elements (measured in parts per million or ppm) provides vital
information on how patterns of wear develop inside the machinery. Regular monitoring will
allow detection of any sudden increase in elements, such as iron, copper, lead or tin, which would
indicate that excessive wear was occurring.

Contamination

Lubricants can be also contaminated in service by fuel. Monitoring the presence of
vanadium, nickel and aluminium provides important information about such contamination.
Other elements such as sodium, magnesium or boron may confirm contamination by sea water
or by the cooling agent.

These analyses are systematically carried out on engine oil.

For other lubricants used on board, such as hydraulic oils, gear oils, compressor oils, turbine oils
etc, there are specific analyses that can accurately indicate the condition of both the lubricant
and the equipment.

RESULTS AT A GLANCE

For shipowners and managers, time is too precious a commodity to be wasted
ploughing through analyses reports.

Each report has a colour-coded alarm which makes the results easy to read
and easy to understand.

URGENT Action recommended
CAUTION Investigation requested
NORMAL Oil in good condition fit for further use

For each alarm, a technical expert makes diagnosis and comments.

Lubmarine's final reports include the results of the last four analyses in one easy-to-follow table,
with symptoms and comments separated from the figures for extra clarity. This simple format enables
customers to view at a glance how the principal characteristics have evolved over the reported
time scale. Reports can be viewed on the web.

Analyses must be carried out on a regular basis. Curves are plotted and extrapolated to
indicate trends. Any deviation from these curves must be investigated further.
Risk of malfunction and breakdown can be minimised.

For the purposes of routine analyses, when manufacturers make no recommendations,
the figures in the table below can be taken as an average.
