Horizon says that the OMV (New Zealand) Ltd operated oil development had made substantial progress recently on building both the wellhead platform and the floating production, storage and offloading vessel (FPSO) components of the 48.8 million barrel oil field.
Perth-based engineering and construction firm Clough Ltd early this year won the approximately $180 million overall contract for the Maari platform fabrication and installation.
The Maari wellhead platform, to be erected in 102 m of water in PMP 38160 some 80 km offshore Taranaki, has had a number of major contracts let for sub-components, Horizon says.
The contract to fabricate the platform was awarded to Kencana HL in Malaysia. The first steel was cut in August at the Kencana fabrication yard where the wellhead platform's base, tower and deck are being constructed
The contract for the topsides module's fabrication went to GPS/Transerve which will be fabricated in Lumut, north of Kuala Lumpur, near the Kencana yard.
All major equipment for the topsides modules has been sourced, while 23 purchase orders have been placed for a variety of equipment packages with only three minor packages remaining to be placed.
The inspection and verification/certification services contract was awarded to Lloyds.
Dockwise won the semisubmersible heavy transport vessel (SSHTV) contract for its vessel Mighty Servant I to carry the wellhead platform to New Zealand.
Tank testing of the simulating float off from the SSHTV, tow to the Maari site and installation has been successfully completed.
Metocean monitoring of the float-off location in Admiralty Bay near DÚrville Island in the Marlborough Sounds of the South Island just south of the Maari site is underway. Resource consent has been received for deployment of a met buoy in Admiralty Bay.
The overall contract for the FPSO was won earlier this year by Tanker Pacific Offshore Terminals of Singapore.
Horizon says in its progress report that fabrication has commenced in Batam, Indonesia of the process modules, vessels and mooring turret.
FPSO conversion is scheduled to start when the tanker Andaman Sea arrives at the Jurong Shipyard in Singapore on 1 January 2007, and will take some 10 months to complete.
Major long lead items have been ordered including steam boilers, turbo-alternators, control system, heat exchangers, water injection pumps, flowlines, riser and umbilicals.
Tank testing of the FPSO, mooring and flowlines simulating a wide variety of met-ocean conditions, including a 100-year storm, has been successfully completed.
The Maari development will involve an unmanned wellhead platform housing the wellheads of the 5 production and 3 injection wells, linked via subsea flowlines to the FPSO vessel anchored 1.5 km away.
