Both vessels will be of the ABS Class, and are expected to be built at one of Nam Cheong’s subcontracted yards in China as part of the company’s built-to-stock series.
Each of the vessels will have a length of 100m and will be capable of accommodating 300 people, with scheduled delivery in the second quarter of 2013.
The vessels will each be equipped with an eight-point mooring system and a 300t crane.
With the latest contract, the order book of Nam Cheong has increased to RMB1.06bn ($167m) for 2012 so far, a figure that has already surpassed the RMB757m ($119.3m) it recorded in 2011.
Nam Cheong executive director Leong Seng Keat said Petronas, Malaysia’s national oil firm, has budgeted RM300bn ($47.3bn) for 2011 to 2015.
"With the boom in the oil and gas industry, more of our Petronas-licensed customers are benefiting from higher utilisation of their marine vessels," Keat said.
In August 2012, Nam Cheong received contracts worth $43.81m to supply one platform supply vessel (PSV) and two anchor handling towing supply (AHTS) vessels.
The ABS-class PSV has been ordered by an unnamed West Africa-based company, and will be 75m long, have 3,000dwt capacity and will be equipped with a Dynamic Positioning 2 system.
Nam Cheong sold one of the 5,150bhp AHTS vessels to a Norwegian-based firm that will own, operate and manage the vessel under a long-term charter contract with Petrobras.
The second AHTS vessel was sold to a shipowner based in the Middle East and will be deployed in the region’s waters.
Both AHTS vessels will have a length of 59m and a bollard pull of 62 tonnes.
