Programmed Total Marine Services – OMV/MODEC

FPSO MV Raroa is 252 metres long and 42 metres wide – a vessel of unprecedented scale in Port Nelson. A converted Aframax tanker, it required extensive works as part of an $80 million project. Kernohan was lead contractor and at the helm of resolving the significant infrastructure and resourcing challenges associated with the project. The scale of works demanded coordination of a large workforce from diverse local suppliers, specialist expertise to meet stringent standards and rigorous project management.

Kernohan commenced its working relationship with Holcim’s Westport cement manufacturing plant in 1977. When the number 2 tyre on Cement Kiln 2 failed Kernohan was appointed lead contractor. What started off as emergency repair developed in to a complex replacement job.

With anticipated closure in 2016 it was critical that a cost effective, fit for purpose solution be found for the remaining lifetime of the plant. The chosen option was a first – a new untried method using a laminated tyre.

Duration 12 days

Budget $1.2 million

  • Worked extensively with Holcim and suppliers to explore and source a fit for purpose replacement tyre option.
  • Given the complexity, scale and risk the project involved 6 months pre-planning.
  • Kernohan assumed the lead project management role coordinating all parties, suppliers and delivery of work.
  • 40 x tradesmen worked rotating 24/7 shifts to convert.

“Their integrity at work was highly valued and to be honest, they’ve set the standard for me in future roles.”
