(Bloomberg) — Daewoo Shipbuilding & Marine Engineering Co., the world's third-largest shipyard, led advances in rivals in South Korea and Singapore on expectations of orders for drill ships and offshore platforms in Brazil.

Daewoo Shipbuilding gained 4.7 percent to 47,850 won, the highest in four months, in Seoul. Sembcorp Marine Ltd., the world's second-biggest maker of oil rigs, rose 2.6 percent to S$4.41 in Singapore, the highest this year.

Petroleo Brasileiro SA, owner of the largest Western Hemisphere oil discovery in three decades, plans to order 40 drill ships and platforms worth about $30 billion, according to a company statement yesterday.

The Brazilian company, also known as Petrobras, plans to spend $112 billion through 2012 to increase its oil and natural gas production and expand its refining and distribution units.

"Petrobras' plan triggered expectations demand for offshore projects will increase and will benefit shipyards at a time when there are concerns about cargo-ship demand weakening," said Yoon Pil Joong, an analyst at Samsung Securities Co. in Seoul.

He has "buy" ratings for Daewoo Shipbuilding and Samsung Heavy shares.

Sembcorp Industries Ltd., parent of Sembcorp Marine, rose 4.8 percent to S$4.60. Keppel Corp., the world's biggest oil rig maker, added 1.9 percent to S$11.86.

Samsung Heavy Industries Co., the world's largest builder of ships used for drilling in deep waters, closed unchanged after gaining as much as 2.5 percent.
