Logimatic implements Logix-based solution to improve ship-wide control and alarming capabilities on 80-year-old yacht

 

Background

Launched by Queen Alexandrine in 1931 and commissioned in 1932, Her Danish Majesty’s Yacht (HDMY) Dannebrog serves as the official and private residence for Queen Margrethe II of Denmark, the Prince Consort and members of the Danish Royal Family when they are on official visits overseas and on summer cruises in Danish waters.

Operated by the Danish Navy, HDMY Dannebrog has seen a number of upgrades and enhancements during its illustrious career. During the latest improvement effort, Danish system integratorLogimatic, was awarded the contract to design and install a modern shipboard control and monitoring system.

Logimatic had already undertaken a number of significant and highly successful marine control solution installations for the Danish Navy. For this project, the system integrator once again turned to trusted collaborator Rockwell Automation – with whom it had shared its previous successes – for an advanced monitoring infrastructure that would help bring the eighty year-old ship up to modern marine standards.

Challenge

“The major issue we faced was the age of the ship,” explains Søren Abildsten Bøgh, application engineer, Logimatic. “Both the outdated physical on-board restraints and the plans available to formulate the design and installation weren’t in a format that complimented modern design procedures.”

As well as the age of the ship and the restricted space available, Logimatic also faced significant time constraints. “We started in late November 2011 and had to get the project finished by February 2012,” Bøgh explains.

The electricians would have to find all the signals and the functions of all the analogue lines and the control system had to be finalised before Logimatic was able to start programming. During the installation phase, numerous issues became apparent to the third-party company undertaking the electrical wiring issues, which impacted Logimatic’s work on the design and operation of the control system. As a result, the control solution engineering had to remain fluid right up to the point of handover in order to accommodate the unforeseen issues raised during the installation and testing phases. “There was significant information flow backwards and forwards,” explains Bøgh, “and we saw almost continual changes relating to design issues.”
