Jack Tighe Ltd was awarded the contract to scaffold, encapsulate, carry out surface preparation and apply protective coatings to Bent 27 – 34 within Immingham East and West gas Jetty’s.

We awarded the scaffold and encapsulation to one of our approved sub-contractors, SGS Ltd and carried out the surface preparation and painting using our own ICATS accredited, directly employed operatives. Six scaffold operatives and three painting operatives have been involved on this contract, supported by permanent on-site supervision and a designated contracts manager. Site inspections have been carried out by our Nebosh accredited H&S Officers and ICORR qualified paint inspectors.

All work was carried out over tidal water in the Humber Estuary, necessitating the use of a safety boat and the wearing of life-jackets and full body harnesses when working on the pilings. Tidal movements meant that, when working on the pilings, working hours had to be adjusted accordingly so as to avoid down-time and give the maximum possible curing time for the coatings.

Surface preparation of the steel surfaces was done by a combination of mechanical means using rotary wire brush and / or angle grinder fitted with flexible paper backed sanding discs and dry spot grit blasting. Paint application was by a combination of spray, brush and roller. Company owned plant, consisting of blast pots, diesel bowsers, spray pumps, clean air packs, spill kits, gas monitors, generators and a welfare unit were used along with hired compressors.

The specification was provided by Sigma Coatings and comprised:

  • Jetty: spot blast areas of corrosion to SA 2 ½, sweep blast all other areas to create a key and apply one overall coat of Sigmashield 880 to achieve a DFT of 425um
  • Jetty Pipework and Epoxy painted structure: spot blast areas of corrosion to SA 2 ½ , sweep blast all other areas to create a key, apply spot prime with Sigmacover 256 and then apply a full coat of the same material before applying an overall coat of Sigmadur 550.
    Jetty Handrails & all Pipework on East / West gas jetties: mechanically prepare all areas of corrosion to ST3 and apply coatings as to Jetty Pipework.
  • Environmental considerations were paramount on this contract and drip trays were used under all compressors with spill dry absorbent being available throughout at the workface. All paint materials were stored in a bunded storage container within the works compound and only small quantities required for each day’s operations were taken onto the jetty area.

Our client was Associated British Ports and the works were completed in November 2015. Contract commencement was in September 2014 and the final contract value was circa £693,000.
