Schlumberger has affirmed its commitment to the deepwater market with launch of the DeepSTIM II - the second in a new line of advanced stimulation vessels for deepwater service. The new vessel surpasses the size of the first DeepSTIM by 10 ft., making it the largest stimulation vessel operating in the Gulf of Mexico. The new-generation DeepSTIM design integrates Schlumberger expertise in marine, mechanical, electronic and chemical engineering, and DeepSTIM II incorporates design improvements made after the first vessel was launched in 1999. Measuring 270 x 56 ft., the vessel's large capacity provides reliability in severe weather and allows the vessel to remain at sea for long periods.
