EMRI A/S

Established in 1972, EMRI's core business is in the Manoeuvre and Steering Control of Ships, Bridge Instrumentation and Machinery Control Boxes. We use System Design and production ready documentation tools to react to a customers requirements.

Since the trend of the shipyards is to prefer a few, large system integrators, EMRI has chosen the role of the subcontractor's, i.e. only in very seldom cases will we deliver a system directly to a shipyard. Therefore EMRI usually teams up with one or two of the market leaders in integrated bridge and machinery systems and tailor-make attractive packages, that integrate optimally with other subcontractor systems.

The key areas to our success are in efficient design and documentation. Drawings and database files are exchanged over the internet on a daily basis with contractors, shipyards and other subcontractors. Final Instruction Books are produced both on paper and in electronic format. From 1999 the preferred formats are Autodesk's Drawing Web Format and Adobe's Portable Document Format.

JOYSTICK CONTROL SYSTEM

This is a low speed manoeuvring aid, useful in situations where the operation's area is of limited size, and where objects to avoid or to approach are visible and close. Any ship manoeuvre is the result of a combined translation and rotation of the vessel.

Rotation results from the application of turning power, i.e. opposing side forces fore and aft to the vessel. Translation results from the application of "thrust", i.e. side forces fore and aft in the same direction, and main power ahead/astern.

Under normal hand control, the captain estimates the necessary turning power and thrust, and by a complicated process decides the control strategy, i.e. the application of rudder angles, main propeller RPM and pitch and bow and/or stern thrust.

Under joystick control, the captain still estimates the turning power and thrust, and then simply orders the amount and direction. The thrust vector computer then selects a combination of settings of the available manoeuvre organs, able to develop the requested amounts.

Under DP control, the whole process is automatic: The ship is held on position by the combined use of all thrust-devices and controlled by satellite DGPS signals.
