JANUARY 18, 2013 — Manahawkin, N.J., headquartered JonRie Intertech LLC has introduced a new JonRie Series "220" double drum escort / assist winch.
JonRie delivered its first three ship sets last year to Caribbean Tug-Z and Seabulk Towing. The fourth ship set will be delivered this spring to Seabulk Towing and a fifth ship set — a larger version — is to be installed on a new Marine Towing of Tampa ASD this summer.
All five ship sets feature JonRie's constant tension (active heave compensation) / constant scope systems.
All five tugs should be in service by the start of 2014 and feature independent drives for each drum and JonRie's standard foot pedal for hands free operation. Also featured on each drum are JonRie's tension read out system. The bow winches also share their hydraulic power unit (HPU) with aft capstans and towing winches.
The winches were originally designed for submarine docking but now are being used to handle barges and as a redundant line on all ship assists and escort work the tugs will be involved in.
This type of redundant line tethered to the ship is standard on the Panama Canal.
