MEL South Island Office

2018 has been a busy year for the South Island team who have relocated the MEL office from Christchurch to Nelson. MEL Nelson offers the full suite of services of MEL and has a team of 4 senior people.  The South Island Manager is Colin Brown.

This year MEL Nelson has established a new office based in Richmond, Nelson and we have now been in operation one year. Establishing a new engineering business has required persistence and we are now supplying Engineering services to a number of local timber processing industries, a Fish Oil Processing plant and local ports.

Work has included guarding audits and design for the pulp and paper, meat, hop and vegetable processing industries working with Worksafe in some instances.  We have been working alongside other engineers in the design and construction of a Mussel Oil extraction plant using high pressure CO2 to extract the oil.  

2019 will be about maintaining quality service and increasing our presence as our client base grows.

On behalf of the South Island team I would like to wish everyone a very happy and safe Christmas and a prosperous new year.

APPITA Pan Pacific Fibre Value Chain Conference

Darrin Hawkes and Greg Brown attended the conference in Rotorua from the 4th to the 6th December and took the opportunity to catch up with existing and new customers in the Pulp and Paper sector. Darrin presented a paper titled “Achieving Stretch Targets in Minimum Time” as part of the maintenance section of the conference. His example was the project management work MEL completed for a 350 m2 weld overlay of a continuous digester in a Kraft pulp mill. MEL was responsible for overall project development and management. Specialist international weld overlay contractors were engaged to operate a mechanised welding process with multiple local contractors providing support.

The work took place February this year during an extended shut. Working 24/7, utilising 9,500 man hours it took 16 days to complete. The overlay consumed 24 t of welding wire, 40 t of argon and was all managed via access through a 1.2 m diameter port in the vessel.
