The bacteria can cause a variety of infections, including pneumonia, meningitis and blood-poisoning.
It is understood four employees have been infected, with tests being carried out on others.
"The Public Health Agency (PHA) is working with the Health & Safety Executive Northern Ireland (HSENI) and Port Health colleagues to investigate a cluster outbreak of pneumococcal disease at Harland and Wolff, Belfast," a spokesman for the PHA said.
"A small number of employees working at Harland and Wolff have been confirmed as having pneumococcal disease.
