Case Study: Guaranteed Power - Patria

For 50 years, the Linnavuori tunnel complex in Nokia has been home to a repair shop for heavy-duty engines operated by the Finnish Navy and various industrial plants.

A tunnel complex excavated in the rock of Linnavuori, Nokia, houses a modern repair shop whose facilities and equipment represent the state-of-the-art in Europe. This is Patria’s repair shop for diesel engines, which mainly specialises in large diesel engines operated by the Navy and nuclear power plants.

The same tunnel complex also houses a unit that services and repairs gas turbine engines from aircraft and industrial plants. Seppo Tamminen, head of Patria’s diesel engine unit, says that diesel engine maintenance is one of Patria’s lesser known but key competence areas.

“The repair of large maritime diesel engines began here as early as 1964,” Tamminen says.

A clientele representing both the civilian and military sectors
Our first proper diesel engine client was the Finnish Border Guard, which had the Mercedes-Benz (current MTU) engines of its Lintu class patrol boats serviced at the Linnavuori facility.
At about the same time, the first Russian-made M50 engines of the Finnish Navy’s Nuoli class motor gunboats were sent to us for servicing.

Since then, nearly all engines of the Finnish Navy combat vessels have been serviced at Patria.

“Bursting with power, the 56-cylinder radial engines of the Tuima class missile boats are particularly worth mentioning,” Tamminen says.

Over the years, the repair shop’s clientele has expanded to include the civilian sector. In the early 1990s, the emergency power generators at the Olkiluoto and Loviisa nuclear power plant were added to our service range.

Over the last few years, Patria has maintained different types of diesel engines operated by the Army armoured units, shipping companies, ferry transport companies, mining companies and various industrial plants.

Assignments at short notice
Each year, 12 to15 large diesel engines are overhauled in Linnavuori, a figure supplemented by a large number of smaller projects. In addition, a large amount of maintenance and installation work is carried out aboard customers’ vessels, or on other premises.

“Overhauls involving extensive work are performed at Patria’s repair shop, while smaller jobs can be carried out on the customer’s premises,” Seppo Tamminen states.
Erkki Martikainen, a type rated engineer for maritime engines, says that maintenance teams set off on assignments at short notice.

“Rapid action is required if, for example, a problem develops in a vessel’s main engine, and the ship needs to set sail after refuelling,” Martikainen says, illustrating a typical scenario.
Newer engines may also develop problems with their electronics, for which Patria’s experts can provide solutions.

Reliability is everything
Maritime engines are one of Patria’s key product groups. With regard to their maintenance, reliability is at a premium, Erkki Martikainen states.

“Reliability is the outcome of work undertaken by our professional personnel, of our adherence to the guidelines provided by the engine and device suppliers, and of our using original spare parts. These are the principles that we strictly adhere to,” Martikainen says.

For example, the main engines of the Navy missile boats are given an overhaul every 6,000 operating hours. Intermediate maintenance is carried out every 3,000 hours.

“At Linnavuori, engines are subjected to test runs following maintenance. This ensures that the engines will work properly, their adjustments are as required and no leaks occur,” Martikainen says.
Less extensive maintenance and replacement operations are performed by the customers themselves. Even then Patria is often involved, for example, in the maintenance of removable components such as fuel system devices.

“The customer detaches such devices from the engine and ships them to us. At Linnavuori, we inspect the devices and return them to the customer after the completion of maintenance.”

Spare parts for ageing engines
A testimony to the high standard of expertise found in the Linnavuori tunnel complex lies in the fact that Patria has long been the authorised repair shop for MTU engines in Finland. Well-functioning cooperation with engine manufacturers ensures that Patria is also able to obtain spare parts for older engines.

“Repairing old engines rarely poses a problem. For example, MTU is able to deliver parts and seals subject to wear and tear straight off the shelf for engines that may be up to 50 years old,” Erkki Martikainen says.

In addition to engines, Patria provides maintenance services for other devices in vessels’ engine rooms.

“On combat vessels, for example, our service covers the entire power line from engines to clutches to shafts to gears, and further down to the water jet impeller,” Seppo Tamminen says.
Patria’s diesel engine repair shop carries out joint projects with the company’s other business areas. For example, the extensive mid-life upgrade project for the Rauma Class Fast Attack Craft was implemented in collaboration with Patria Systems. Linnavuori had responsibility for overhauling the vessels’ propulsion system.

Lockheed Martin, DSME to Co-Build Multi-Mission Combat Ships

(From Press Release)  Lockheed Martin and Daewoo Shipbuilding & Marine Engineering (DSME) have signed a comprehensive teaming agreement to partner on the Multi-mission Combat Ship (MCS), which is based on a DSME hull design and intended for the corvette market.


Both companies bring valuable experience and unique capabilities to the teaming arrangement. Lockheed Martin has a proven track record of developing and integrating complex systems into a wide variety of U.S. and international naval vessels. DSME is one of the world’s largest shipbuilders and has a rich history of producing highly capable naval vessels for the Republic of Korea and other international customers.

“DSME’s MCS hull design coupled with Lockheed Martin’s expertise in program and systems integration will allow the team to bring this capable ship to the international marketplace at an affordable price,” said Joe North, Vice President of Littoral Ships and Systems at Lockheed Martin Mission System and Training.

“Together, we bring not only the best experience, expertise and resources, but also the right dedication and focus to offer coalition navies a multi-mission corvette-sized ship designed to meet future threats,” he added.

“This Teaming Agreement on MCS and strategic cooperation will not only provide our customers with high capability vessels on time, but also further facilitate our two companies’ joint efforts in exploring opportunities on a global scale.” said Deog-Soo Kim, Vice President and the Head of the Naval & Special Ship Business Management Division at DSME.

“Moreover, the Korean government is pursuing ‘New-Economic Growth Activation by Defense Industry’ as one of the state development agendas and this agreement is a good example of achieving the objective,” he continued.

Lockheed Martin and DSME are continuing to explore additional business opportunities in the international naval market where integrated, multi-mission corvettes will play a vital role in coastal protection as well as regional operations.

SECOND KONGSBERG AUV AND SUBSEA TECHNOLOGY EQUIPPED INDONESIAN SURVEY VESSEL READY FOR DUTY

The second of two 60 metre oceanographic and hydrographic vessels designed and built by OCEA in France for the Indonesian Navy was handed over following a commissioning ceremony in Jakarta this March. The KRI 934 Spica, is the sister ship to the June 2015 delivered KRI 933 Rigel, which is already on active survey duty in Indonesian waters. Both are highly advanced aluminium multi-purpose ships, with ‘Full Picture’ technology packages delivered by Norway’s Kongsberg Maritime.


OCEA’s unique vessel design and aluminium construction is ideally suited to achieving highly accurate survey results at speed due to producing less cavitation across the hull during surveying. According to OCEA’s Director of Sales, Fabrice Epaud, this enables Kongsberg Maritime’s hydroacoustic systems on board to operate optimally and deliver highly accurate data at speeds up to 15 knots, close to almost twice that of standard survey operations.

“Aluminium is smooth in the water, hence creating less bubbles, which will enable the Indonesian navy to get the best results possible from the KONGSBERG subsea equipment,” explains Epaud. “It’s our job to make the best of the survey equipment we are installing for the customer, so we place a lot of emphasis on the integration when constructing a survey or multi-purpose vessel. The result is considerably more efficiency, which can save the customer time and money by completing more survey miles faster, and to a very high standard.”

The Indonesian Navy’s new vessels will be utilised to gain a better understanding of the seabed and waters of the Indonesian archipelago, so have been equipped with the most efficient and up to date technical and scientific equipment. OCEA worked in partnership with SHOM, the Hydrographic and Oceanographic Service of the French Navy, to optimise the selection and integration of the hydroacoustic equipment in addition to providing scientific training for crews and technical assistance in Indonesia.

The identical KONGSBERG scope of supply for both the KRI 934 Spica and KRI 933 Rigel includes a HUGIN AUV per vessel, EM 2040 and EM 302 multibeam echo sounders, EA 600 single beam echo sounder and side scan sonar, in addition to HiPAP hydroacoustic positioning systems. Both vessels have their own 8 m survey launches also equipped with Kongsberg Maritime subsea technology including the EM 2040 multibeam and EA 400 single beam echo sounder. The KRI 933 Rigel also makes use of an advanced Kongsberg Maritime Dynamic Positioning system.

“This was an extensive ‘Full Picture’ subsea delivery for two very advanced vessels designed and built by one of the leading shipyards in Europe,” said Helge Uhlen, VP subsea Sales, Kongsberg Maritime. “We have worked closely with OCEA to ensure the vessel owner can get the most out of the technology we have supplied, helping them to operate effectively and generate precise results even when surveying at high speed. It’s testament to the sophisticated design and construction methods OCEA uses and our on-going co-operation that survey results from the KRI 933 Rigel have already surpassed expectations.”
