McDermott International has completed a wellhead platform for Pemex, one of four the Mexican state player will put to work on its Ayatsil-Tekel heavy oil field in the Gulf of Mexico.
The US contractor landed the contract to build the eight-leg Ayatsil-B jacket and deck for the Bay of Campeche project in May 2012 with a bid of $90.1 million.
The 11,535-tonne structure, which was built at the company’s Altamira yard in Tamaulipas, Mexico, has now been delivered to Pemex.
Read more on the Ayatsil project in Friday’s upcoming issue of Upstream where Pemex is reported to have increased the number of bidders to provide a floater.
Ayatsil-B was awarded by Pemex along with three other platforms in 2012: Operadora Cisca landing Ayatsil-A for $98.1 million at its Tuxpan yard in Veracruz; ICA Flour Daniel grabbing Ayatsil-C at its Industria del Hierro yard in Tampico for $94.1 million; and Commsa getting Ayatsil-D at its Arbol Grande yard for $88.9 million.
The 15-slot platforms will all have topsides weighing about 5000 tonnes each, including accommodation modules. Pemex mandated that the bidders include specifications for the flagship project to handle lighter crude for blending.
Pemex has already suffered one significant setback at Ayatsil, the Ayatsil-A jacket slipping into the sea during a transport and installation operation. It is understood that skirt pile guides were compromised in a heavy ocean swell, allowing the jacket to descend to the seabed unguided in a water depth of 126 metres.
Ayatsil has been attributed with a critical role in helping Pemex claw back some of the output that has been lost due to decline at the Cantarell field.
Future development plans at Ayatsil involve a floating production, storage and offloading vessel.
