SELF PROPPELED RING WASHER / WASHING RAFT

As the years have past, salmon cages have grown larger and the need for new and dedicated equipment to the handle the larger cages has arrisen. Conventional ring washers are mounted on service boats or connected to work boats with hoses and cables and their use is time consuming and labour intensive. Servi is now proud to present a 100% self propelled and self contained ring washer which is capable of all washing operations and requires only two operators.

During the development of the wahing raft, technical personnel from the farms, cage manufacturers and washing contractors were all consulted and provided valuable input to the the new raft concept. The teamwork resulted in a raft which covers all washing and service needs in an efficient, safe and economical manner. The ring washing raft has been tested for two years and has successfully washed 170 kilometers of cage rings. The raft has excelled during trials and users have been particularly pleased that no dissasembly of the net cage anchoring system is required and work is carried out in a safe and comfortable fashion. The time taken to wash one ring is around 20 minutes.
