Mexican state oil company Petroleos Mexicanos on Wednesday signed a technology-transfer agreement with four domestic shipbuilders and Spain's Barreras.

Pemex said in a statement that the goal of the accord was "to share experiences with the aim of boosting the capabilities of Mexico's shipbuilders and auxiliary industry."

The agreement was signed by Barreras, which is Spain's largest private shipbuilder and is 51 percent controlled by Pemex, and Mexican shipbuilders Talleres Navales del Golfo, Servicios Portuarios, Fundiciones Rice and Servicios Navales Industriales.

During the signing ceremony, Pemex CEO Emilio Lozoya reiterated his company's commitment to revitalizing Mexico's long-stagnant shipbuilding sector by promoting the construction of new vessels at competitive prices.

This effort is evidenced by Pemex's fleet-renewal program, which calls for the construction of 22 "minor-fleet" vessels such as tugs, barges, lighters and specialized multipurpose vessels in coordination with the Navy Secretariat, the statement said.

"As part of this important initiative, 10 units will be built by Mexican shipyards with the support of the domestic auxiliary industry," Pemex added.

Pemex officially took control of the Hijos de J. Barreras shipyard in Vigo, a city in the northwestern Spanish province of Galicia, on Dec. 16.

Pemex and Barreras closed their investment deal on Nov. 26, with the Mexican oil giant purchasing a 51 percent stake in the Spanish shipyard for 5.1 million euros ($6.9 million). EFE
