Navis NavDP4000

Overview

Field of interest of the company founders since early 1980 was the development and tests of the automatic control system for hovercraft, type of the ships with much faster dynamics comparing to majority of the offshore vessels.

This experience and fundamental knowledge of the subject was the base for the successful lunch of the first system on board of “Candy Pioneer” in February 2000.
Around 800 systems now serve our customers on board of the ships in major oil and gas offshore development areas.

Unique algorithms help us to keep the position of the vessels with fast dynamics, lightweight and shallow draft — fast crew boats and jack-up rigs vessels, or in cases when fast reaction from the system is required.

In 2002 we have delivered dynamic positing system for the first water jet driven fast crew boat in the world. Since than we deliver around 150 systems to boats with different propulsion configurations — from simple in build and operation fixed pitch propellers and to recently developed and delivered hybrid driven ones.

Opinion after software upgrade of DP Control System:

“Actually, this updated software is perfect!

There are new Min Power Heading and Hold Area modes when vessel is on standby outside of installation’s 500m zone. When these modes are ON, diesel generator power consumption is minimum in compare to previous Dynamic Positioning software version, 1 x Bow thrusters (BT) is stopped and ready for auto start on demand by DP system. No more noise from thrusters high RPMs. Vessel is like weathervaning and following environmental forces within predefined by DP operator sector.

Full DP Mode: Bow thruster Group Bias – Excellent function. Bow thruster are working in opposite direction to avoid frequent clutching in and thus saving bow thrusters contactors. Same, one Bow thruster is running and in case the system demands more than 25% of thruster force, then 2nd bow thruster is being started and working in required direction.”

HIL test

Since the first installation we use hardware-in-the-loop technique for software debugging and hardware checks.
As a matter of fact we arrange system commissioning first in our office, as that is much easier to fix all the issues at home having the whole developers team behind the system.
While we are connecting the system to the test bench we check connection of hardware components as well. Only after that we deliver and commission system on board.
Today we use this approach not only for the new systems, but every upgrade, literally each single component before being shipped is tested on a HIL test bench.
Confirm, we do that even for non class systems.

Main benefits

The simplest user interface

HIL test of every system delivered

Set of fuel saving modes

Custom control modes even for single ship

Service where it is needed

Transparent and predictable cost of system ownership

Commissioning and sea trials

Having perfectly pre-tuned system and checked documentation we can provide fast commissioning for the yard and very stable system for the owner. Bearing in mind small number of failures due to extensive tests at manufacturing facility, we can keep compact service team comparing to the rest of the companies in the industry.

Critical applications

For critical application we have developed extended logging system, which allows to have ideal base for both incident investigation and preventive maintenance.

Fuel saving

Set of fuel saving modes is available for applications where it is possible to decrease accuracy of position keeping and as an exchange reduce fuel consumption.

Footprint on the bridge

We currently have the most compact system on the market in terms of footprint on the bridge, addressing challenges of the projects with space constraints on the bridge.
