The committee also found some substandard equipment while visiting two projects -- Computerised Container Terminal Management System (CTMS) and Vessel Traffic Management Information System (VTMIS), confirmed the committee sources.

With the two, a total of six projects, including purchases of three container vessels, an excavator, an ambulance boat and a bay cleaner, which are currently being examined for alleged irregularities and corruption, involve around Tk  250 crore, the sources added.
