TECHNAVA SA, as an exclusive certified representative and Service Partner of Yoowon Industries Steering Gear & Deck Machinery, utilizes an experienced local team of service engineers and, upon reviewing your vessels’ equipment details, is able to provide you with a draft maintenance plan for YDFT (Ram type) steering gears based on a 5-, 10-, 15- and 20-years overhauling interval, along with the estimated days required for the job completion.

In reference to planned maintenance:

• It is recommended for the crew to proceed with the required measurements once per year. These measurements will be further evaluated by our Yoowon team – both mechanical and operating conditions of the S/G – and we will revert with necessary comments and actions if required. The relevant Pre-Inspection check sheet can be provided upon your request.
• There is a minimum plan for overhauling, as proposed by the makers of steering gears, on a 5-, 10-, 15- & 20-year basis.

However, this is subject to the existing condition and maintenance done so far. From our side, we can support a minimum as outlined below:

We recommend, at a minimum:

• Hydraulic pumps overhauling
