Denso Protects Footbridge Suspension Wire

Winn & Coales Denso Steelcoat 100/400™ system was chosenby Hampshire Rigging Services of Romsey to protect thesuspension of the footbridge at Thames Ditton Island, Surrey.

Corrosion Prevention for Steel Suspension Wire Rope - United Kingdom Vol: 34 No. 1, Date: 09. 2017, Page: 3

For this recently completed project the Denso Steelcoat™ systemwas applied to a steel wire rope which is fitted to the four tower topsfrom which the footbridge is suspended. The wire rope where thegroove fits in is approximately 1 metre in length and 44mm diameter.

Particular attention was given to the application of Denso Steelcoaton the four tower tops and the anchorage bars, which had previouslysuffered from some corrosion. Following surface preparation, the DensoSteelcoat system applied by Hampshire Rigging Services consisted ofDenso Hi-Tack Primer™ followed by Densyl Profiling Mastic™ for fillingawkward profiles. This was then followed by Denso H i-Tack Tape™,Denso Ultraseal Tape™ and Denso Acrylic Topcoat™.

project and did much of theassembly and construction ofthese sections top-side beforeslinging the large, wrappedassemblies down into theground. Once the remainingconnections were joinedtogether below grade, theywere finished being Densowrapped and then backfilled.

The process of assemblingthe sections and then protectingthem before going in theground was much easier fromthe contractor’s perspective asit helped minimize much of thein-trench work and permitteda better overall application ofthe Denso system.

Some of the Denso Petrolatum Tape System installation was applied prior to placing in-situ.

The pipeline loopings of a section of the existing Victorian Transmission System and Northern InterconnectSystem will provide natural gas security of supply on the East Coast of Australia.

The final stage, being loops 6 to 9 of the VNIE pipeline project was awarded to Spiecapag Lucas JV (SCL)in late 2015, where construction was carried out nearby the country townships of Seymour, Wangaratta andChiltern in Victoria, Cootamundra and Young in NSW. Loops 6 to 9 saw more than 162 km of pipe delivered

between Seymour and Young at strategically placed holding yards some 500km apart.

Denso Protal 7200™ - Australia’s PipelineCoating of Choice

APA Group’s Victorian Northern Interconnect Expansion (VNIE) Pipeline Project comprised ofthree stages, which have been constructed over the last 3.5 years. The VNIE pipeline loopingsfall within both states of Victoria and New South Wales (NSW) and is made up of 16” and 18”

2LFBE coated mainline steel pipe. Stages one and two of the pipeline loopings were constructedby McConnell Dowell and Nacap Australia, which consisted of loops 1 to 5 and were

completed between 2014 and mid-2015.

Denso Australia was again engaged for the supply of Denso Protal 7200™ high build epoxy for field jointcoating materials and mainline repairs by SCL given the strong working relationship, which has been formed

over recent years namely supplying APA’s Eastern Goldfields Pipeline Project and Jemena’s QueenslandGas Pipeline Looping project using Protal 7200 for FJC.

The selection of Denso as thesupplier of choice is a testamentto the confidence that bothSpiecapag, Lucas and DensoAustralia have developed overthe course of the previousprojects and the suitability ofProtal 7200 as a user friendly,high performance, high buildepoxy coating system.

The project itself was carriedout over a 15 month periodthrough some extremelychallenging constructionconditions due to unseasonalrecord setting rain events acrossNorthern Victoria and SouthernNew South Wales. Nevertheless, constructioncontinued and saw the coatingof more than 8,000 mainlinefield joints, applying Australianmanufactured Protal 7200. Theepoxy was supplied in 800 litrekits to be utilised with SCL JV’sthree purpose-built coating rigs.These comprised of pluralpumps and generators for sprayapplication of the Protal 7200.

Manual kits of 1.5 litres weresupplied for tie-ins and 400mlrepair cartridges for any repairs.

The project in total saw morethan 25,000 litres of Protal 7200consumed during theconstruction period. This project,along with APA Group’s EasternGoldfields Pipeline, Jemena’s

BPGIC is an important tank storage operator who’s licenced activities in Fujairah,UAE cover the storing of (crude oil, fuel oil, all kinds of oil products and gas), as

well as building, managing and investing in refineries including theextraction and exploration of crude oil.

After discussions with the consultants MUC, BPGIC approved theuse of the Denso Steelcoat Tank Base Protection System™ for alltheir tanks on their new Fujairah storage facilities terminal. Thisapproval was based on the successfull record of the Denso systembeing used by other tank farm operators in Fujairah. The Densoprotective system was applied by contractors Audex. The projectwas completed in March 2017.
