The letters 'K' and 'S' of Keppel Shipyard are combined to create the simple and bold form to project the "honest, vigour, dynamism and progress" of the company to the world.

The logo was created for the incorporation of the shipyard on 1 September 1968 as a wholly Government-owned commercial operation. It previously existed as the Dockyard Department of the Port of Singapore Authority.

A logo competition was launched in mid-February that year and invites were sent out to various schools in Singapore. Keppel did not engage a profession advertising agency because it wanted "to encourage local talents to demonstrate their skills" instead. The only stipulation was the logo had to be in red and white in keeping in its corporate colours.

Of the 182 entries received from 75 participants, this logo by 18-year-old Sim emerged the winner. The second year Advertising Art student of the Baharuddin Vocational Institute won $500 for her effort. Consolation prizes of $50 were also presented to Eng Siak Loy, Wong Fook Seng, Sim Kwan Ser, Chew Tai Theng, Lee Tee Song and Tay Siew Chiah.

In 1996, the logo was replaced when Keppel consolidated its different companies to form Keppel Corporation.
