Power systems contractor uses engine monitors

Schaller, a manufacturer of monitoring and safety systems for large diesel engines and gas turbines, has signed a cooperation agreement with Burmeister and Wain Scandinavian Contractors.

Schaller, a manufacturer of monitoring and safety systems for large diesel engines and gas turbines, has signed a cooperation agreement with Burmeister and Wain Scandinavian Contractors (BWSC), a turnkey operator of power systems.

In addition to cooperating on field tests, BWSC is intending to use Schaller's monitoring and safety products for the protection of power plants, and to ensure the highest level of availability and reliability of production of electricity at highly competitive capital costs.

Schaller 's monitoring and safety devices the Bearing Condition Online Monitoring System (BeCOMS) and the Single Compartment Oil Mist Online Detection System (SiCOMS) can be easily adapted to and used on any two- and four-stroke engine.

The BeCOMS Mk III analyses the time course of thermoelectric voltage generated by friction of any moveable part in the engine and triggers an alarm if a pre-set level of friction is exceeded.

In addition to triggering an alarm like the former versions, it reliably identifies the compartment in which the engine failure appears.

Even slightest scratches of the crankshaft on bearing shell surfaces are monitored.

The alarm system shuts down the engine automatically, or allows operators to stop the engine.

The new SiCOMS does not use any suction or piping arrangement.

Instead, it continuously measures and analyses the oil mist concentration inside the engine compartments and includes a data logger and viewing software.

This allows the continuous observation of oil mist formation during any time of its development.

Both systems can be easily integrated into the control and management system of ships and power plants, using the Modbus and Canbus interfaces.

Remote control and remote monitoring of both monitoring and safety devices BeCOMS and SiCOMS, is additionally provided by either a separate Schaller 'data evaluator unit' or simply a PC.

The sophisticated software features remote monitoring of up to 16 SiCOMS sensor units on one PC, or 4 BeCOMS devices.

Approval by classification societies such as Germanischer Lloyd for both systems is currently pending.
