SeaShield™ Systems Provide Long-Term Protection for Jetty Piles at Ullapool Harbour
60 years of innovation brings you the green line valve
In 2020 , Shearwater Marine Services were awarded a contract to install protection for jetty piles at Ullapool Harbour in the Scottish Highlands , on behalf of The Ullapool Harbour Trust .
Muller Coax have developed a patented energy saving valve which can offer up to 80 % power saving on similar sized valves . The new green line series has been specially developed as an energy efficient series of solenoid valves . For this reason directly controlled standard valves from Muller coax has been paired with completely new patented control electronics within the terminal box .
The valve has an optical position indicator as standard on the terminal box for the open / closed position , the position indicator as also available as an electrical signal . Flanged or
threaded from 15mm through to 40mm orifice and 100 bar rated the design in the electronic circuitry within the box allows :
• Different opening / closing speeds at the flick of a switch which helps to eliminate vibration and water hammer in the pipework .
• Holding voltage as low as 7.5 watts for the smaller 15mm valve reduces the power consumption when energised for long periods and the solenoid remains cold .

As consulting engineers on the project , Wallace Stone specified the use of SeaShield™ Systems supplied by Winn & Coales ( Denso ) Ltd to protect the jetty piles . SeaShield Systems have an extensive history of providing long-term corrosion protection to marine structures .
Shearwater Marine Services used a combination of the SeaShield 2000FD™ and SeaShield 70™ Systems on the piles and various supporting crossbeams on the structure .
SeaShield 2000FD consists of Denso Paste S105™ , Denso
The finished SeaShield Systems applied to the jetty
Marine Piling Tape™ and an outer HDPE jacket , which is hydraulically tensioned before being secured with stainless steel fixings .
The SeaShield 70 System was used to protect the crossbeams and is an excellent option on areas where piles have obstructions . This system consists of Denso Paste S105™ , Denso Profiling Mastic™ , Denso Marine Piling Tape™ and Denso Glass Outerwrap 70™ .

Are you ready to ship under ISPM15 regulations ?
For any UK business shipping goods within the EU , the latest changes to regulations will be a vital consideration . Wooden packaging , including pallets , must now meet ISPM15 standards when being shipped . This regulation ensures pallets have been treated to eradicate pests and are then stamped to reinforce this action has been carried out . While demand and prices for these types of compliant pallets will be on the rise , there are alternatives to consider .
The best alternative to Wooden Pallets , is Plastic Pallets . Plastic Pallets completely avoid the ISPM15 regulations , are more hygienic and reliable , and making the switch now will minimize any potential disruption to your supply chain now that these regulations have come into effect .
