Our engines were approaching 22,000 hours and we again decided to renew the engines. They are more reliable, and it works out more cost effective than overhauls. Reliability is essential in our business. A breakdown in season is not an option.
We have used Scania Engines and Twin Disc Gearboxes in our larger vessels for over 35 years. It was a logical replacement to our vessel Solent Cat. Originally fitted with Scania DI14’s and Twin Disc MG5114’s in the year 2000, we stuck with the same reliable power train. However, this upgrade, we decided to opt for the electronic controls for the Gearbox as well as the engine.
The last Scania’s were electronic, so we chose the MGX Twin Disc to complement the system, giving us Twin Disc EC300 electronic controls. This preserves the drive train thoroughly and protects as well as prolongs the whole system.
Our installation was completed by our own staff and management. By the day of sea trials, there was minimal work to be done, followed by a very successful running trial proving an excellent installation with impressive results. We took a little extra time and managed to achieve alignment as close as four thou across the whole coupling gave a very smooth running engine.
The gearbox is connected to the shaft via an R&D Coupling to increase the smoothness of the vessel and its drive.
We would wholeheartedly recommend all parts that we have used this installation that include Scania, Twin Disc and R&D.
When ordering our new vessel, we specified the Twin Disc Quickshift MGX-5136SC as this would keep continuity amongst our fleet and also the crews were familiar with operation of this gearbox, the smooth and direct drive through the main engine ease of controls, the main factor is the technical support, with back up service that M.I.T provide to our fleet.
The heavy demands placed on the marine gears and propulsion systems by constantly changing from ahead to astern when bed levelling, have been met with 100% reliability from the Twin Disk MG 514 units. It was an obvious choice to choose Twin Disc for our new vessel, the high level of reliability makes them ideally suited for the type of work to be undertaken.
As a family, we have used MIT for two generations now. We have purchased at least 4/5 gearboxes from MIT for our various boats. We have always found them to be very informative, and helpful. I wouldn’t consider using anyone else for gearboxes.
ESL provides the critical service of pilot boarding and landing to the Ports of London and Medway. In order to help it meet the needs of the business, Twindisc gearboxes were selected for our latest pilot boats, Estuary Elan and Elite. Over the past 30 years, we have forged a strong working relationship with MIT. The excellent customer support and response times MIT provides, coupled with its years of experience and expertise in the industry, has been essential in maintaining ESL’s operation.
MIT is one of the very few companies that understand the need to get a commercial boat back out to sea ASAP! When we have a mechanical breakdown MIT are our first phone call…. and then the lifeboat!
We have four Twin Disc units on our charter boats operating day trips to St Kilda 50 miles West of the Outer Hebrides, and we have never had a bit of trouble from them.
We have covered well over 100.000 miles with one vessel now and have never had a spanner near them.
