In the meantime Valles was further building up on its close personal relationship with the Japanese building families, in particular with the Namura family's shipbuilding group, the Higaki's family's Imabari Group and lately with the Tsuneishi Group's Kambara family. In fact, Valles has been part of the history of these Groups and it was a Valles ship, the 42,000 dwt MV FEDERAL BULKER, that in 1971 was the Namura shipyards largest vessels to that date. The Federal Bulker too served faithfully under the Valles fleet and was only sold after more than twenty-three years of service.

Also in 1971, the Group took delivery of the MV SEATRANSPORT from Namura, a 16500 dwt modern bulk carrier with cranes.

It was once again with the Namura Group that Valles placed an order for a series of three 37,000 dwt oil tankers, the first oil tankers to be constructed by the shipyard and the first new building oil tankers for the Company. These ships the MT SEASERVICE, MT SEABORNE and MT SEASTAR were delivered to Valles over a period of time in 1972 and 1973. These vessels were chartered to the Mobil Oil Company for ten years and were successfully operated in the harsh North Sea environment. Whilst the Seaservice and Seaborne served all their useful life under the Company's flag, the Seastar was sold in 1983.

In 1987 and 1988 the Company secured two long-term charters with Navios Corporation of Stamford, USA. To service these contracts the vessel purchased two high specification panamax bulk carriers, the NAVIOS BULKER and the LUCKY BULKER.

In 1991, the Group took delivery of the MT SEAFALCON from Imabari and it was the first new building to be registered under the Hong Kong registry.

In 1995, Valles transferred its day to day operations to Vancouver, Canada under Valles Steamship (Canada) Ltd.
