Singapore's first Port Operations Control Room Centre (POCC) de-commissioned, as new upgraded centre takes over control. The decommissioning of the centre at at Tanjong Pagar Complex (POCC-TPC) marks the retirement of Singapore's first POCC after more than 28 years of faithful service in ensuring navigational safety of vessels in the Singapore Strait and Singapore's port waters. First commissioned on 1 May 1984, POCC-TPC initially used VHF radios to manage vessel traffic in Singapore until the first radar based Vessel Traffic Information System (VTIS) was installed in 1990.The VTIS allowed POCC officers to see the positions of vessels in real time on a screen and provide navigational assistance to these vessels.
