TTS moves into the AHTS market

The AHT winches can be delivered with various features and customized adapted. TTS can now offer 200 tons, 300 tons, 400 tons, 500 tons and 550 tons winches in various models like for example drums, drum sizes and spooling devices.
According to the company: – We offer our products with high pressure hydraulic (HPH) drive. Today these winches are generally delivered with low pressure hydraulic drive, but our high pressure drive solution is fully adapted to the AHTS market and can match any requirement from our customers. We have been working very close to some of the major ship designers and are very confident with our solutions. By using HPH drive we can easily adapt to new requirement and future demands from owners, class society and authorities to technology for use on AHT winches which we are working on already now and hope to launch in 2008. Today there are several misunderstandings in the market for low pressure hydraulic (LPH) vs HPH. These misunderstandings are especially towards the following topics:
• Reliability
• Dynamic breaking
• Quick release
• Torque
Reliability
The winch power requirement are the same whatever drive solution used, so based on this the LPH system requires five times as much oil flow as the HPH system to create the same effect.
TTS: – With this you will get five times as big oil pillar between valve and motor acting as a spring. You also have to accelerate a larger mass substance to a wanted speed and this will also require longer time. Larger components because of larger oil flow also results in larger inertial masses.
– We are using high torque low speed radial piston motors from Hägglunds. These motors have supreme performance and are well adapted for AHT winch drives.
– When it comes to oil cleanliness our system can operate with a cleanness of NAS 9. We are using return filters and blocked filter alarms to avoid damage on the equipment. For example LPH require typical cleanliness of 9 -11 which in fact are almost the same as HPH. And due to this fact the LPH more or less require the same when it comes to flushing and installation as for HPH.

TTS consist now of over 1250 employees all over the world and is one of the major suppliers of ships equipment. To the offshore market TTS can offer cranes in various sizes, anchor handling/towing winches, and a lot of other equipment like moon poles, smaller winches like anchor windlass, tugger winches, capstans. TTS is aiming to be a more and more complete supplier to the offshore segment. Earlier this year TTS acquired Sense EDM. This is a company that delivers drilling equipment both onshore and offshore and will be a focus area in the TTS Company aiming for the offshore segment.
