Offshore New Zealand
Pro-Safe Production Services
Up to January 2016
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.
The project team typically consists of four crew members at any one time and includes skilled blaster/painters, experienced foremen and a Project Manager. The shift rotation is a weekly fly-in/fly-out arrangement of two crew members at a time. All crew members working on the ship must hold a current offshore medical certificate and have completed the Basic Offshore Safety Induction and Emergency Training (BOSIET).
TBS’ first three months of the painting campaign maintenance has included coatings refurbishment around the accommodation block completed via dry abrasive blasting with full containment. There have been some isolated areas where wet abrasive blasting has been used around dust critical areas. Going forward, maintenance work will commence in zone one production areas, meaning the introduction of UHP water jetting to the project.
One of the major challenges for the project team is working on an offshore facility where sea and weather conditions can be extreme. The Umuroa is a 258m long x 46m wide vessel and is bow anchored to the sea bed. This anchoring system ensures the ship is always facing into the wind but leaves the ship subjected to sea pitch and rolling, which presents an ongoing dynamic challenge to all onboard.
In addition to this, the weather also affects the fly-in/fly-out rotation of staff, with flights sometimes being delayed or postponed due to weather and or sea conditions.
