SEYMOUR, Ind. (November 1, 2011) -
Cummins Inc. (NYSE: CMI) announced today that the new QSK95 engine will be configured as a ready-to-install Offshore-Drilling Power Module (ODPM) with 2.1-megawatt (MW) output. As the world’s most powerful high-speed diesel, the 95-liter 16-cylinder QSK95 enables the ODPM to generate dependable prime power with high-load factor capability for oil and gas platform operations.
The QSK95 engine is rated 3000-hp (2125 kWe) at 1200 rpm to align with a standard ODPM output node used for moored semi-submersible drilling rigs, jackup rigs, drillships, floating and gravity-based production platforms.
While the QSK95 achieves 2.1-MW with 16-cylinders, other large high-speed diesels require 20-cylinders to achieve the same output. Compared with medium-speed engines, the QSK95 reduces the space envelope by up to 40 percent, with approximately 33 percent less weight.
When maximum power is needed for long periods, or when sudden overload occurs, the QSK95 has deep reserves of strength to handle it with ease. The QSK95 Modular Common-Rail System (MCRS), with up to 2200-bar high-pressure fuel injection, results in smoother, quieter and more fuel- efficient operations.
For critical emergency power, the QSK95 ramps up in seconds to provide seamless power without interrupting operations, due to the faster transient response provided by four compact turbochargers with the simplicity of single-stage air-handling.
“The need to drill deeper and increase productivity is driving the demand for stronger and more efficient offshore power modules, and our new QSK95 ODPM will be ideally suited to handle these higher electrical loads with non-stop dependability,” said Erik Drewry, Director – Cummins Oil and Gas Business.
“With drilling rigs and platforms using as many as six power modules, the reduced space and higher fuel-efficiency of the QSK95 prime mover provide a clear advantage. Operators can also expect to see higher levels of uptime availability than they have experienced from an ODPM generating 2.1 megawatts,” added Drewry.
The QSK95 ODPM will be available in a cost-effective, standardized base package, or with the option of easy customization to meet specific installation needs. The control system comes with a full suite of operational data, multilingual touch screens and safety protection features, providing easy interface with the rig’s local network with remote monitoring available.
The new QSK95 module will join the QSK60 Offshore-Drilling Power Module with 1.3-MW prime power output, recently introduced by Cummins. The two drilling-module engines share the same fuel system, turbocharging and electronic control systems to offer the benefit of installation and service commonality.
Low Emissions With Less Fuel
The QSK95 ODPM will offer a major advantage when it comes to meeting EPA Tier 4 and IMO very low-emissions marine regulations. By utilizing Cummins own Selective Catalytic Reduction (SCR) aftertreatment system to replace the exhaust muffler, the module retains an almost identical envelope.
Importantly, using SCR requires no change to the cooling or ventilation requirements of the power module in order to meet challenging emissions levels, retaining the global applicability of the QSK95 engine. While achieving Tier 4 low-emissions, the Cummins SCR system is capable of achieving fuel savings of 5 percent to 10 percent, lowering the overall cost of operation by more than the cost of Diesel Exhaust Fluid (DEF) required for SCR. These fuel savings are incremental to that of the QSK95 meeting Tier 2 emissions without aftertreatment.
Increased Uptime And Serviceability
The QSK95 ODPM has been designed with more inherent reliability to ensure the highest possible uptime availability. The engine is configured to provide faster and easier servicing procedures, with simple access to all cooling, oil and fuel system maintenance points on the engine.
Service intervals are a minimum of 500 hours, with the option of much-extended oil change intervals available by using the ELIMINATORTM oil purification system, which is mounted on the engine.
The goal of a leak-free engine is achieved by premium “press-in-place” seals on all critical joints, such as flywheel housing, gear housing and oil pan-to-cylinder block.
Cummins Electronic Control Modules (ECMs) provide a high level of processing power and memory to monitor, control and protect the engine systems, with easy interface for diagnostics.
