Motor-Services Hugo Stamp (MSHS) operates a turbocharger division. The business is based in Fort Lauderdale, Florida, and has provided turn-key services for the maritime and stationary power industries for almost 30 years.
The MSHS turbo division recently deployed its advanced retrofit technology on a retrofit job involving a Napier turbocharger. MSHS successfully completed the retrofit from a Napier SA105 to a Napier NA355 turbocharger on a Ruston 12 RKC engine, providing stationary power in the Caribbean. The engine, an aged installation, suffered from limited power output due to low boost and high exhaust temperatures. The Napier SA105 turbocharger was no longer supported by the original equipment manufacturer’s (OEM) current product line and the availability of spare parts and tooling could no longer be guaranteed without significant price increases and long lead times, which could lead to extensive engine down times. For ageing applications approaching the point where they need major component replacements, retrofitting an engine’s turbocharger is a cost effective alternative to replacing all the turbocharger’s core components.
The design of the NA355 that replaced the Napier SA105 meant that no further modifications to the application were needed, as the NA355 specifications met the requirements for the retrofit application. It offers superior aerodynamic technology and is more efficient than the SA105 turbocharger. New technology prolongs the time between overhaul (TBO) contributing to lower maintenance costs throughout the engine’s remaining lifespan. Newer turbocharger models are built with maintenance friendly access to main components and are manufactured using the latest technology and superior materials, which offer a higher wear resistance.
MSHS provided the complete new Napier NA355 turbocharger matched to the engine’s specification and the customer’s requirements. The MSHS engineer performed the retrofit on site within five days. The engine downtime was kept to a minimum to reduce the impact on the customer’s daily operation. After the retrofit, the engine and turbocharger were closely monitored during the test run to ensure safe operation.
The Napier NA355 improved the engine’s efficiency thanks to its newer technology. This reduced the engine’s fuel consumption by up to 4 per cent, leading to lower operational costs. The engine’s longevity will be extended through lower operational temperatures and reduced thermal stresses on the combustion elements. Using the latest technology enables MSHS to provide long-term support including customised inventory solutions which guarantee superior responsiveness. In times of increasing pressure to improve fuel consumption and reduce exhaust emissions, retrofitting an existing engine with a new turbocharger is an effective method of prolonging the engine’s lifetime and increasing its efficiency while decreasing its environmental footprint.
Providing turbocharger services and spare parts has been an integral part of the company since its inception. The MSHS turbocharger division provides comprehensive services and renowned technical expertise, which is what led Napier to appoint MSHS. In addition to providing retrofits at the turbocharger reconditioning centre, MSHS engineers are able to restore turbocharger blades as well as other critical parts to OEM specifications. The starting point for every blade reconditioning process is a thorough non-destructive test. After determining the exact extent of the damage to the turbine blade the engineer uses aerospace quality welding material and state-of-the-art technology to restore the blade’s affected areas and re-shape its geometry. Cost savings are in the order of 80 per cent of the cost of a new turbine blade. A turbocharger works in high temperatures and its critical parts have to withstand a huge amount of stress. Chipped or cracked blades pose an unacceptable operational risk.
MSHS is also the authorised distributor and service centre for most of the world’s major diesel engine and turbocharger manufacturers. The turbocharger workshop provides round the clock services to the Caribbean, Central America, Europe, and the USA and it is looking to expand further. The company proudly operates in conjunction with quality management systems standard ISO 9001:2008 certification. It provides marine users and stationary power plants with qualified and experienced OEM factory-trained service engineers and technicians to carry out repairs and overhauls for Napier, MAN, MET, PBS and KBB turbochargers.
MSHS’s turbocharger division is equipped to handle a complete range of turbocharger repairs. It offers the widest range of inventory parts in the Americas for various turbocharger brands and models, including Napier product ranges 5, 7, and 8 series; Mitsubishi’s MET; MAN’s axial TCA, NA/S, NA/T9 and radial TCR, NR/S; PBS Turbo’s PTR, PTD, and PDH; KBB’s axial M-type and radial ST, HPR, and R-types, for major components such as turbine rotors, nozzle rings and cover rings.
Retrofit installations of Napier turbochargers have been completed both on board vessels, and on stationary power production plants located in the Caribbean and the United States. MSHS’s latest retrofit programme results in prolonged engine life, reduced time between overhauls, and an improved environmental footprint. The company’s newest retrofit service is designed to avoid turbocharger failures and to provide improved engine performance.WTG
