Application

The ship’s chief engineer required several modes of operation in order to

optimize the performance of the yacht’s electrical system.

During normal operation, the load on the ship can be supplied by one genset, but when seas are

rough and the ship’s stabilizers are running, there is a need for additional generation.

In this mode of operation, both gensets must run continuously.

Also, the ship needs to be connected to shore power when in port.

In order to eliminate a blackout on the ship during the power transfer,

and to reduce the amount of load generated to the shore power,

a scheme was developed to provide an automatic closed transition using a Woodward SPM‐D.

Using the sequencing functionality of the EGCP‐3. the control is configured to

start an additional unit two seconds after the load on the master unit exceeds 75%.

When the load reduces to below 30%, the slave unit is removed from the system after 60 seconds.

The controls needs to be able to trade master/slave relationships,

so a switch is used to place one control in Auto and Run w/ Load (Master)

and the second unit in Auto (Slave). Both controls have the option to operate in either

mode—so if sequencing needs to be avoided, the operator can place both

controls in Auto and Run w/ Load, and both units will share the entire electrical load.

Sea Jewel is a 160 ft (49 m) yacht that uses two Caterpillar 3304 gensets for electric

power. The ship’s original control system needed repair but had been discontinued;

additionally Lloyd’s registration was required to comply with new insurance

guidelines. So Sea Jewel Ltd contacted Governor Control Systems Inc. (GCS) to

purchase, install, and commission two Woodward EGCP‐3 LS units to control these

two Cat gensets. The EGCP‐3 LS combines engine, generator, power system,

switchgear, bus and generator monitoring, protection, and control functions in a

single, compact, and cost‐effective package. Woodward representatives were

present to help in the commissioning.

Electrical System

The Sea Jewel’s two Cat 3304 gensets are rated for 80 kW each. Each genset is

controlled by a Woodward EGCP‐3 LS and can connect to the ship electrical load via

its generator breaker. The load can also be supplied by shore power when in port.

To synchronize the boat to shore power, a Woodward SPM‐D delivers

synchronization signals to the two EGCP‐3 LS units and closes the breaker when

phase and frequency are matched.

Conclusions

The commissioning of the Sea Jewel was a success, and operation of an EGCP‐3 and SPM‐D illustrated the

adaptability of Woodward controls to any application. By applying the EGCP‐3 LS units to the control of

the Cat gensets and the SPM‐D for synchronizing the shore power, the Sea Jewel now has a reliable

system to begin their chartering business this summer. Woodward would like to thank Sea Jewel Ltd and

Governor Control Systems for their time and energy on this project and congratulates them on a great

control system.

The DVP is designed to control valves and actuators with either limited angle torque

(LAT) or brushless DC (BLDC) motor types. The driver positions based on resolver

feedback located on the valve or actuator. The DVP uses the latest in Woodward

control architecture, the robust controller to provide high-speed precise valve control.

The DVP is designed for plug-and-play installations on many valve types. Woodward

has integrated smart technology into the new generation of valves and actuators

called an ID (identification) module. Upon connection to a valve or actuator equipped

with an ID module, the DVP automatically reads critical valve-specific information to

set up the driver. After this auto-detection and customer configuration, the DVP is

ready for use. Both pre-manufactured connectorized cables and terminal connection

models are available.

The DVP is available in multiple configurations:

• Ingress Protected IP30 or IP66 models available

• Connector or terminal block outputs; conduit option available on IP66

• 125 Vdc or 24 Vdc power input options available

• EGD (Ethernet), CANopen, Analog (4–20 mA or 0–5 Vdc), PWM configurable input options

• Electric actuator driver

• Triple redundant EGD (Ethernet) or dual redundant CANopen digital communication options

• IP30 or IP66 enclosures

• ID module compatibility for plug-and-play operation

• Connector, terminal block, or conduit options

• Certified for International Hazardous Locations (CE Mark/ATEX, IECEx, CSA) and Marine

Applications

The Woodward DVP is the state-of-the-art driver for electric

actuation. It features a rugged and compact design.

The DVP is designed for use with various Woodward valves and actuators.

It provides positioning based on a demand signal from the control system.

Multiple input type configurations allow the DVP to be used with many different turbine controllers.

The driver supports redundant installations.
