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.
