Maui A

The Maui partners ran an extensive maintenance programme both onshore and offshore, including upgrading a vent tower on the Maui A platform and round-the-clock work at the onshore production station. The shutdown (the largest since commission in 1984) has cost an undisclosed several million dollars.

Maui Project

The project took 2 years of preparation, including a trial assembly/disassembly & test lift of the crane on shore.

In December 2010 the crane was mobilised from NZCG’s Auckland premises to New Plymouth. The boom was detached - to meet the maximum lifting capacity of the rig crane - and shipped with the carrier to the Maui A rig from the Port of Taranaki on 22 December 2010.

Preparation started at the 3rd of January and the actual shutdown commenced 26th of January and was completed on 23 February. The operation took place in a 24/7 setting, where marginal weather conditions gave limited slots for safe lifting.

Maui A - companies involved

OGST Involvement

NZ Crane Group got involved in the planning for the offshore part as early as 2008, when Group General Manager Cameron McCahill was approached to do a feasibility study deploying a mobile crane to the Maui A platform.

The Maui field, located in the Taranaki Basin about 35 kilometres west of Oaonui, produced 52.8 PJs of gas and 1.5 million barrels of oil in 2009.

Upon completion of the study, New Zealand Crane Group was awarded the contract to mobilise a suitable mobile crane from New Plymouth to the Maui A platform. The Grove GMK6220L crane with a boom length of 72 m + 13 m fly jib was selected for the job. It assisted with partially dismantling the old vent stack tower and replacing of corroded sections with new ones.
