OCS’s hydraulically powered hose spoolers are an important part of the jetting spread as it houses the 8” water supply hose (fed from the jet pump) & 4” air-hose, configured in a chiksan such that the water/air supply are continuous as the spooler reels out the hoses. The water supply hose is of high strength anti-kink type where it is durable and prevents kinking/collapse during operation. In order to keep less tension on the hose and protect the hose, the deployment and recovery should be assisted by deck crane. A pressure gauge is installed on the inlet of the spooler to obtain the direct pressure reading before the water enters the jet sled.
