First Quarter 2021 Shaft power components

The marine industry is tough. Whether you are operating a single vessel or an entire fleet, challenging sea conditions, rising costs and increasing environmental and safety regulations are affecting profitability and operational efficiency. Technical knowledge gaps and reduced crew numbers present further challenges; staying ahead in the marine industry requires a concerted effort across many fields.

When a ship is out at sea, outside support is a long way off and rough seas present extreme working conditions. Equipment reliability and flexibility is therefore paramount. SKF’s marine solutions encompass easy, cost-efficient products and a full portfolio of high-quality components designed to deliver high reliability, serviceability and long service life to keep customers’ operations running smoothly.

The company’s extensive marine portfolio includes seals, rolling, slewing and plain bearings and housings, fin stabilisers and steering gear solutions, condition monitoring, power transmission products (couplings), automatic lubrication systems and related services.

For most machinery, even small oil leaks can present a big problem. Today’s increasingly aggressive lubricants can threaten seal performance, damaging vital equipment which can lead to unplanned maintenance and subsequent downtime. Fitting the right seals will reduce friction, retain lubricity and keep contaminants out of the system. SKF has the necessary expertise to help identify the right seal for each individual application. Simplex and all SKF seals are designed to provide cost-effective, reliable sealing performance. Available in a range of designs, sizes and materials, these products can be delivered promptly around the globe.

The operational efficiency of the line-shafting of a ship’s propulsion plant is mainly determined by the quality of the bearings used. Simplex Intermediate bearings, characterised by their short shell length, are developed especially for this purpose as short, plain bearings.

The running properties of the bearing metal have been optimised with a technically advanced bonding of the bearing metal and shell and can be precisely aligned to avoid edge loading. The vital lubrication of the bearing is safeguarded in the Simplex bearing at all times, even at low shaft speeds. Temperature sensing, monitoring and cooling systems are available for unfavourable operating conditions.

Stabilising systems and steering gears play an essential role in improving the all-important on-board experience for passengers and crew. SKF’s wide range of fin stabilisers and steering gear solutions are designed to provide a vessel with better roll reduction on rough seas and can help maintain speeds while reducing fuel consumption.

Ship uptime relies on high performing and available machinery on board. In tough sea conditions, assessing the condition of auxiliary machinery without having to disassemble the equipment is more important than ever before. SKF’s condition monitoring solutions enable complete asset condition maintenance for the entire fleet, or a single ship, and are designed to serve a fleet CM program as a foundation of the fleet Condition-Based Maintenance (CBM) strategy that complies with the class societies´ recommendations and requirements. SKF’s condition monitoring solutions and all related equipment are aligned with ISO and class requirements.

Power transmission products play a key role in overall bearing performance. They are literally the vital link between moving parts in equipment. To help optimise overall machine performance, SKF has developed a wide range of power transmission products engineered to give engineers more design choices according to performance and cost considerations.

Coupling systems are critical components that connect vital applications such as propeller shafts, propellers and rudder assemblies. If couplings are off by just a fraction, they can be prone to premature wear and shortened life cycles. SKF coupling systems are designed to resist high torques to provide maximum strength– reducing downtime while keeping operations running.

Vibration, high mechanical loads, contamination and moisture are all threats to bearing and gear service life in marine applications. Like any mechanical system, moving parts in engines, gearboxes, propeller shafts, steering gears, winch drives, deck cranes or other auxiliary equipment require proper lubrication to function optimally. SKF and Lincoln automatic lubrication systems help to optimise marine operations by enabling efficient and safe fleet maintenance of all types of vessels.
