It was only in 1965 that Valles placed an order with the Hakodate shipyard in Japan for its first new building, the MV SILVER SHELTON. The Silver Shelton was a 16000 dwt bulk carrier, classed with Bureau Veritas. Since that time the "Silver" fore name has been proprietary to Valles and there has always been at least one vessel in the Valles fleet with the "Silver" or end with "BULKER" and the oil tankers are generally named to begin with "SEA".

In 1967, Valles placed an order for its first new building outside Japan, when a contract was signed with Taiwan Ship Building Corporation now known as China Shipbuilding Corporation, Taiwan for the MV SILVER CLIPPER a 27,000 dwt bulk carrier. This vessel was the largest vessel to be built at that time in Taiwan or China and was designed by Valles' in house team led by naval architect Mr. Ikeuchi. The vessel proved to be very lucky for the Company and since then there has always been a SILVER CLIPPER in the Valles fleet. The present SILVER CLIPPER is a 151,000 dwt bulk carrier, coincidentally also built by China Shipbuilding Corporation, Taiwan in 1993.

Valles and CSBC Taiwan have enjoyed many record breaking contracts, the next of which was in 1973 when the Company placed an order for the first panamax bulk carrier to be built in Taiwan, the 60000 dtwt bulk carrier, the MV HERCULES BULKER. This ship faithfully served under the Valles flag for more than twenty years and was only sold to Greek interests in 1994.

In 1972 the Groups founder, Mr. C. S. Koo, passed away leaving Mr. K. M. Koo the sole beneficiary of his estate.
