New offshore drilling power module
Here’s the new QSK60 offshore drilling power module.
It’s rated at 1,855 hp at 1,200 rpm with a 10% overload capability and is integrated with an AvK DSG99 alternator at 2,150 kVa and 690 v. The maker says its unit is suited for durability, reliability, and power density requirements of high-hour and hard-duty cycle applications such as drilling power modules with no major midlife top-end overhaul requirement.
The modular common rail (MCR) fuel system enables full-authority electronic control over fuel timing, quantity, pressure, and delivery rate shape. Precision control over the number of injection events enables optimum performance, fuel economy, smooth power delivery, better idle stability, and reduced engine noise, as well as providing the capability for an in-cylinder Tier 2 emissions solution, the firm notes. The company points out that it has optimized the MCR fuel system for load requirements in drilling applications, allowing the power module to achieve a 4-9% fuel economy advantage over competitive Tier 1 and Tier 2 products of similar speeds and ratings. The MCR fuel system also gives the QSK60 power module a fine-tuned fuel calibration to meet all marine regulations, including EPA Marine Tier 2, IMO Tier 1, and EC Directive Regulations.
The firm designed its product for the lowest installation cost for repowers by using customer interfaces similar to competitor packages for quick installation in rigs that allow for the easiest accessibility. The QSK60 is also designed with common mounting arrangements for drilling applications.
The power module offers an electronic information system with a C-Command Elite and Elite Plus panel designed to protect and enhance engine performance and manage cost. The electronic information system and special panels provide customers rugged controls that are able to stand up to marine environments and use flexible presentations of engine parameters, multilingual touch screens with full-color text and graphics, and remote panel options to simultaneously monitor up to eight engines.
