A Follow-up Pair of RAmparts 3200 CL Tugs for Repeat Owner

November 24, 2017

In 2011, Ocean Pioneer and Ocean Perfect, the first two RAmparts 3200 CL tugs developed by Robert Allan Ltd. exclusively for Cheoy Lee Shipyards, Hong Kong were delivered to M/s Ocean Sparkle Limited, the largest Indian tug owning and operating company with more than 80 tugboats under its fleet. Since then, 33 sister tugs of this CL series have been constructed by the same builder for their clients around the world. It is very rewarding to see Ocean Sparkle Limited returned to Cheoy Lee Shipyards, ordering two more units of the same series of this constantly improving design from this highly experienced and competent shipbuilder. The two newly built tugs, Ocean Leader and Ocean Legacy left Hong Kong for their home port of Mumbai recently. They are scheduled to be deployed at an LNG terminal in India.

  • Length overall: 32.00 m
  • Beam, moulded, extreme: 12.40 m
  • Depth, moulded: 5.40 m

The two new tugs were designed and constructed to Lloyds’ requirements with the following notation:
