Umuroa Offshore Painting and Maintenance Contract
TBS’s New Plymouth based operation secured the maintenance painting project, for Pro-Safe Production Services New Zealand, onboard the ship “Umuroa” in January 2013.

The Umuroa is a floating platform storage and offload (FPSO) facility located in the Tui Oilfield off the Taranaki coast.

Specifically the project is for the ongoing refurbishment programme of the ship’s decks, equipment and process modules (piping, vessels and structural equipment), all of which are subject to the severe marine environment. Corrosion control on this vessel is extremely important to meet and comply with the requirements of Maritime New Zealand and operating certification requisites.

Makatote Rail Viaduct Life Extension Project
The Makatote railway viaduct is located between Ohakune and National Park in the Central North Island and is a critical link in the North Island Main Trunk Line.

The last full repaint of the viaduct was carried out during the 1950’s with subsequent touch ups completed in the 1990’s. This life extension project will be the first full refurbishment of the steel structure in 60 years. The scope of the project includes:

the design, build and installation of a complex access and containment system that can be moved along the structure as work progresses; removal, containment and disposal of the existing lead based coatings system; replacement of heavily corroded steel components;
strengthening of the steel trusses with the addition of new steel components; and application of a new red oxide coatings system to restore the viaduct to its original form.

Methanol Reformer #2 Turnaround Project
Methanex contracted TBS to remove existing brick and ceramic fibre modules from the “coffin walls” and auxillary burner zone inside the Meth 2 Reformer.

The shutdown involved the management of 50 staff and some 30,000 labour hours. Work was performed over a 6 week period involving closely supervised, night and day shift rotation on a 12 day fortnight basis.

Such an intensive work program ensured that the plant was out of commission for the shortest time possible so as to minimise cost while not compromising Quality or Health and Safety standards.

Rotary Kiln Relining Contract
Bluescope Steel undertake programmed maintenance shutdowns on each of its 4 Rotary Kilns.

On a ‘staged basis’ TBS typically perform 2 programmed shutdowns per year whereby each kiln is inspected and areas of degraded refractory brick lining are identified for breakout and replacement.

Generally this would involve replacement of a 25 – 30m section of the 4.6m diameter Kiln and casting of the Dam Section. Work associated with shutdowns often extends to the specialist breakout and reinstallation of ‘gun-sprayed’ refractory in other plant items associated with the Kiln.
