CIMC Raffles to Deliver AGOSTO-12 to Coastal Contracts Ahead of Pemex Job

China's Yantai CIMC Raffles Offshore Ltd. (CIMC Raffles) will deliver AGOSTO-12 -- the company's self-designed jackup gas compression service unit (JUGCSU) -- to Malaysia's Coastal Contracts Bhd from its Longkou Shipyard in China on Friday, Aug. 28 before setting sail for the Gulf of Mexico to commence a contract, the firm said in a press release Thursday.

CIMC Raffles' TAISUN200B-design AGOSTO-12, classified by the American Bureau of Shipping (ABS), consists of a rectangular hull with four cylindrical legs support. The hull, measuring 246 feet (75 meters) in length and 164 feet (50 meters) in width, is equipped to operate during the Category III summer hurricane season in the Gulf of Mexico. It can cope with a maximum wind velocity 188.9 feet or 57.6 meters per second in 180 feet (55 meters) of water depth, 62 feet (19 meters) air gap, 49 feet (15 meters) soil penetration and 54 feet (16.5 meters) maximum design wave height.

AGOSTO-12 has 4 sets of hydraulic pin jacking system with 3,200 metric ton (MT) normal jacking and 6,000 MT storm holding capacity -- currently the most advanced hydraulic jacking system in China. The JUGCSU has the world's largest diameter cylindrical legs -- with a diameter of 14.7 feet (4.5 meters) and a length of 367.4 feet (112 meters) -- to meet water depth requirement, harsh environmental conditions and high jacking load as well as a small bearing area spudcan.

The JUGCSU, which has an environmental-freindly dual fuel engine to reduce emissions of sulfide and other pollutants, "can swap the diagonal legs without the need of ballast adjustment during preload, which save 75 percent preloading time relative to single leg preload," CIMC Raffles said.

On arrival in the Gulf of Mexico, AGOSTO-12 will commence operations at the Cantarell oil field for Petroleos Mexicanos (Pemex) under a charter with Coastal Contracts.

CIMC Raffles disclosed that the Cantarrell field is currently estimated to flare 600 million cubic feet per day (MMcf/d) of associated gas, causing serious air pollution. This will be reduced to 200 MMcf/d as AGOSTO-12 will recycle the associated gas and reinjects it into oil layer, aiming to raise oil recovery rate.

In a separate announcement, Coastal Contracts revealed that the JUGCSU is contracted to Pemex for $370 million under a 12 year charter for enchanced oil recovery.
