Our Commitment


our commitment

PSA constantly innovates through automation and the use of intelligent systems to enhance its customers' hubbing operations and competitiveness.

Its operations are managed on a network of more than 300 advanced servers.

Applications such as PORTNET® and Computer Integrated Terminal Operations System (CITOS®) have given PSA the edge to achieve greater levels of productivity and efficiency.

Flow-Through Gate

The Flow-Through Gate, introduced in 1997, is a fully automated system that identifies container trucks and gives drivers instructions within 25 seconds.It handles an average traffic flow of 700 trucks per peak hour, and 9,000 trucks per day.

After a manifest is submitted through PORTNET®, the fully automated and paperless process at the gate clears trucks entering the port within 25 seconds, with the following steps:

  • The truck arrives at the in-gate. The driver taps his PSA pass on the Self Service Terminal (SST) and verifies his identity through a fingerprint biometric reader or keys in his Personal Identification Number (PIN).
  • The truck is weighed at the weighbridge.
  • The gate picks up the truck's identity from the In-vehicle Unit (IU) at the dashboard.
  • The gate's Container Number Recognition System (CNRS) captures the container number via Closed-Circuit Television (CCTV) cameras.
  • The system checks the driver's identity, truck's identity, weight and the container number against the manifest and clears the truck for entry.
  • The system sends a message to the driver's mobile phone or Mobile Data Terminal (MDT) on the exact position in the yard where the container will be stacked.

In 1999, the Flow-Through Gate System was conferred an Innovation Award at the 11th UK Seatrade Awards for its contribution to the port's excellence.



Portnet.com, a subsidiary of PSA Corporation, helps the entire port and shipping community to increase productivity and efficiency through the greater use of information technology and the Internet. Through constant technological innovation, Portnet.com has consistently been positioned at the forefront of e-business operations in the maritime and shipping industry.

A PSA flagship IT solution – PORTNET® is the world's first nation-wide business to business (B2B) port community solution and a winning entry in the National Infocomm Awards (2006). It has provided the logistics industry with a single sign-on network portal. Through it, PSA has connected shipping lines, hauliers, freight forwarders and government agencies, helping them to manage information better and synchronise their complex operational processes.

From managing complex transhipment processes of shipping lines (EZShip®), supporting slot exchanges among alliance partners (ALLIES™), enabling companies to monitor performance and make critical business decisions (TRAVIS™), integrating port documentations seamlessly with the haulage processes and workflow (Haulier Community System™) to providing a documentation portal between shipping lines and shippers (CargoD2D™), PORTNET® simplifies and synchronises millions of processes for customers moving their cargo through Singapore.

Over 10,000 integrated users rely on the system's unparalleled capability to provide real-time, detailed information on all port, shipping, and logistics processes crucial to their businesses. PORTNET® processes more than 220 million transactions a year.



PSA Singapore's extensive connectivity and staggering volumes are supported by its IT backbone - Computer Integrated Terminal Operations System (CITOS®). First developed in 1988, CITOS® is an Enterprise Resource Planning system that coordinates and integrates every asset from prime movers, yard cranes, quay cranes to containers and drivers.

Previously, resources were allocated to specific areas of the yard and they stayed there regardless of needs elsewhere. With CITOS®, PSA has a powerful tool that allows the port to manage its equipment and people seamlessly, flexibly and in real-time.

Some examples of how CITOS® directs our port operations:

  • Berthing System
  • Ship Planning System
  • Yard Planning System
  • Resource Allocation System
  • Flow-through gate
  • Reefer monitoring

On a typical day, 60 vessels of different sizes call at our port. Although a high number of them arrive out of schedule, our berth planning system allows most of them to be berthed on arrival.

Planning begins 72 hours before the ship arrives, when the shipping line applies for a berth and sends ship stowage and connection instructions to PSA Singapore through PORTNET®.

Once berthed, the quay cranes unload boxes destined for other ports and load boxes brought in by other vessels. The prime movers are tracked individually via the Global Positioning System (GPS) and distributed dynamically among the vessels.

The prime mover moves off to a container holding area in the yard. There, the yard cranes lift containers from prime movers and stack them in the yard. The sequence is reversed for delivery out of the yard to a connecting vessel.

Containers are not stacked in a random manner. When the information is keyed into the system through PORTNET®, CITOS® automatically generates ship stowage plans and yard layout plans based on factors, such as:

  • Ship stability (for stowage planning)
  • Weight
  • Destination
  • Size
  • Special requirements (e.g. reefers, dangerous goods, out-of-gauge cargo, tight connections)

This allows PSA Singapore to:

  • maximise land use and optimise container retrieval
  • track the location of each container
  • maximise resource productivity by planning ahead

Remote Crane Operations & Control

The RCOC (Remote Crane Operations & Control) system, introduced in 2000, supports the running of Remote Yard Operations for Pasir Panjang Terminal.

It enables PSA Singapore to break away from the conventional yard operations where every yard crane is operated by an operator. The operator only handles the mount or offload of container at the chassis lane. The rest of the action is fully automated by the Overhead Bridge Cranes (OHBC). With RCOC, a 6-fold increase in productivity is achieved. 


RCOC comprises of a suite of system applications that have the following capabilities:

  • Built-in intelligence that optimizes the jobs to be executed and the deployment of Overhead Bridge Cranes and prime movers.
  • Real-time monitoring and control of the remote operations
  • Real-time live video and data streaming of images from the OHBC cameras and data signals exchange between the OHBC and the operator’s consoles to achieve similar quality of service as if the operators are physically on the OHBC executing the jobs.

As a result of the RCOC solution, PSA Singapore achieved the following benefits:

  • Reduced manpower
  • Higher yard productivity
  • Higher comfort level for crane opertors
