1. PURPOSE
Transnet National Ports Authority (TNPA) Ship Repair Facility has been identified by the Government under
the Operational Phakisa programme to undertake upgrade of the existing Ship Repair infrastructure. The
pump house, structural and civil works upgrade forms part of this Government initiative.
The purpose of the specification is to outline the list of activities to be completed by the Professional Service
Provider (PSP) when undertaking the detailed engineering design for the Dry Dock pumping system and its
associated structural, mechanical, electrical, civil components and SCADA system. The appointed PSP shall
incorporate the condition assessment and complete the design development of the Engineering report
inclusive of the budget estimate for executing the project.
2. BACKGROUND
The dry dock pumping system project forms part of the Phakisa initiative 05 for the Port of Durban. The dry
dock pumping system is located in the Graving Dock Area, Port of Durban. The graving dock was constructed
between 1922 & 1923 and commissioned in 1923. The equipment installed at this dock has been in service
for over 90 years. This operational equipment consists of 3 main pumps / motors, valves, piping, auxiliary
pumps, sluice pumps and associated electrical supplies. The operational system / equipment is mainly used
to drain the water from the dock and pumping water into the sea for the purpose of ship repair and
maintenance in the dock. The equipment and infrastructure within the precinct is in poor condition and has
exceeded the design life span. Repairs have become increasingly expensive due to the age of the installation,
spares availability, and the shortage of vendors skilled in the repair of such old equipment. The existing dry
dock operational system as listed in clause 3.3 is in need of renewal due to extended operational service.
The desired requirement is that the process of emptying the dry dock be reduced to an average of 3 hours
with two on duty pumps and one standby per shift. The appointed PSP will be required to undertake a
holistic design development of such system as per the approved standards.

3. SCOPE OF WORK
3.1 Pumping System condition assessment & technical assessment
Conduct condition assessment & technical assessment of the dry dock pumping system to gain an
understanding of the pumping mechanism in order to identify the shortcomings and the necessary
improvements required to achieve the design objective. Track information from Dry Dock personnel
to get clear information of operations, historical maintenance and breakdowns.
3.2 Design Premise
Design premise to be developed in line with the condition assessment outcomes for approval by
TNPA prior to proceeding with the detailed design. Some key indicators are principles of sustainable
design development, low carbon foot print, lower maintenance, optimum functionality, robustness,
desired lifespan not less than 50 years, corrosion protection; discharge rate; energy efficiency etc.
Cogeneration during dock filling procedure to be investigated and incorporated into design of the
new pumping system.
