Oil and Gas Middle East looks at the CM32 range of Caterpillar engines, designed for deep sea offshore drilling.
The deployment of ultra deep sea semi-submersible drillships, rigs, and to reach deeper offshore oil and gas reserves, is becoming a more viable option to oil companies as new discoveries become harder to find.
Looking at the US' current situation in the Gulf of Mexico, there is a willingness to move into waters as deep as 10 000 feet to get access to the estimated 18 billion barrels of oil and 76.5 trillion ft3 of natural gas found in the region.
One thing that is crucial for the rigs, drillships and FPSOs is the provision of reliable drilling power. In such remote locations and depths, you need to ensure that your engine provides constant and efficient output to supply this.
"Once the bit starts turning, power failure is not an option," declares Steven Percy, regional territory manager for Caterpillar Middle East.
And this is exactly what the company strives for in providing their engines. The CM32 is the company's range of medium speed diesel engines designed for offshore drilling in deep locations.
They come in varying sizes - the 6CM32 measuring in at nine metres long and weighing 52 metric tonnes, compared with the 16CM32, which measures 12 metres in length and weighs-in at around 110 metric tonnes.
"There is a trend in the drilling industry for deeper offshore wells because most of the easy fields have been found, so we are seeing a lot of demand for semisubmersibles and drillship engines. Caterpillar is continuing to invest in large engine technology, with new engines currently in development, and we are seeing more enquires coming in every day for these types of product," says Percy.
Percy explains that for engines in remote locations, reliability and durability are absolutely vital. Caterpillar attempts to ensure this through stringent quality control at every stage of the manufacturing process, and through ongoing preventative maintenance.
"It's a multiple stage process, right from component manufacture, engine assembly, engine testing at factory, installation on the vessel, and then very thorough testing and commissioning once installed on the vessel, in order to make sure it meets all of our criteria, as well as the customers criteria," he says.
The King is calling for a halt to exploration, but do you agree?
