Skretting striving for world-class status at Invergordon Published:  03 February, 2009

A £5.2-million refit of the Skretting feed plant in Invergordon last Summer has raised its operating efficiency and Morten Ramsøy, Invergordon plant manager says they are now aiming at world-class status by applying the principles of Overall Equipment Efficiency (OEE).

“We will take performance at Invergordon to totally new levels and outperform all other fish feed factories in the UK,” claims Morten Ramsøy, Invergordon plant manager.

OEE is an internationally proven approach to driving performance efficiency in any production plant. “We use OEE in all Skretting plants and two plants in Norway are at or near world class standard, ranking alongside some of the best car production plants,” says Ramsøy. “Now Invergordon is going to be world class as well.”

Chris Bryden, Invergordon Production Manager, gives more details of OEE. “The three performance indicators used are Availability, Throughput and Yield. Availability is the proportion of time the production plant is working. Throughput is the productivity of the plant compared with the potential production per hour or day. Yield is the proportion of finished product that can be despatched to customers. To get the OEE figure, each is expressed as a percentage and they are multiplied together. is published by Special Publications. Special Publications also publish Fish Farmer, the Fish Industry Yearbook, the Scottish Seafood Processors Federation Diary, the Fish Farmer Handbook and a range of wallplanners.

“The investments increased availability as the lines are more reliable, and throughput, because they run faster. Yield is better because quality is improved.”

The 2008 upgrade included a number of changes and new equipment. One production line was completely re-designed and all three were given new oil and water inclusion systems to make delivery more stable and accurate. Transport systems were changed and sieves re-positioned to minimise dust and fragments in the feeds.

In February 2009, Invergordon will implement major improvements to the oil system, with four 600-tonne storage tanks and totally new heating and dosing equipment. “It will give us much greater flexibility, with the option to blend oils to meet customer demands more precisely with clearly differentiated products,” says Bryden.

“To hit world class, people are vital,” adds Ramsøy. “We are working with all the teams here to ensure they have the necessary competences. 
“My experience with OEE is that investments in equipment and maintenance make most of the contributions at first, lifting the score to about 70. From 70 to 85, it is all about the people — their motivation and hard work are what make the difference and I am confident, with the people we have here in Invergordon, we can make it.”
