The Dutch fleet came under Shell Tankers N.V. in 1954, merging La Corona and the Netherlands Indies tanker operation. Lloyds instead gives La Corona’s formation as 1912 and rename as Shell Tankers in 1959; the B.V. name followed in 1972. Curaçaosche Scheepvaart, formed in 1917, also came under Dutch Shell management. Somerset Shipping’s vessels were bareboat-chartered to and managed by Shell Tankers.
