PEMEX Exploration and Production (PEP) has awarded Spain's Dragados Offshore a pipelay contract worth nearly $200million. Dragados will lay 38km of pipelines linking production platforms in the shallow-water Xanab and Yaxche oil fields in the Bay of Campeche with the Dos Bocas marine terminal in Paraíso, Tabasco state.
Last year (June 2012), Dragados announced the award of an EPC pipeline contract, to a joint venture between it and Swiber, for a 77km, 36-in.-diameter pipeline from the Coastal Connecting Platform to the onshore terminal in Dos Bocas. The project required horizontal directional drilling (HDD).
Four Swiber vessels used in the project, including two construction vessels: Swiber Concorde and Aziz, and two AHTS: Swiber Ada and Swiber Oslo were loaded onto Zhen Hua heavylift vessel and were transported 11,825nm from the port of Labuan, Malaysia and Trincomalee, Sri Lanka, to Dos Bocas.
The Concorde started laying the pipelines from a designated midway point towards Enlace Litoral platform. The Aziz prepared the 16in. crossing and laid the 810m HDD string near to the PEMEX terminal in Dos Bocas, according to Swiber.
Dragados Offshore’s fabrication yard, near the city of Tampico and Swiber office in Ciudad del Carmen provided logistical base and support.
Swyber said "At 77km, this is the longest single laid, trenched pipeline, with the largest pipe diameter of 36in., in Mexico."
