Project Engineer: Ashley Verhulp

Design Team: Albert de Klerk, Tashriq Pandy

Location: Clanwilliam

Year: 2020

Decription: The electrical works associated with a new 400kWp, grid-tied PV solar power plant. This included the installation of 1080x PV panels on the roof of the Spar shopping centre in Clanwilliam, 4x 82.8kVA grid-tied inverters generating a total of 330kVA, interfacing with the main incomer, networking and a secure VPN for remote management and maintenance.

Project: Additive Injection

Project Engineer: Ashley Verhulp

Location: Pretoria, Klerksdorp & East London

Year: 2020

Decription: The electrical and mechanical works associated with a new pneumatically operated additive injection system.

This included the installation of a new pneumatic air line supplied from the on-site compressor, a pre-fabricated pump skid consisting of a pneumatic pump and pressurisation vessel, new additive injection blocks in the road loading gantry and associated pipework.

Project: MV Upgrade

Project Engineer: Ashley Verhulp

Location: Durban IVT

Year: 2019-2020

Decription: The electrical and civil works associated with decommissioning the existing 6.6kV plant reticulation infrastructure and upgrading it to 11kV.

The project included comprehensive load studies, new 11/0.42kV and 11/0.52kV transformer designs , Ring Main Unit (RMU) designs, updated 11kV reticulation layout throughout the plant, safe decommissioning and removal of the old 6.6kV system, and the successful commissioning of new 11kV system, including correct MV protection coordination.

New 525V and 420V MCCs were also constructed to ensure that main LV distribution boards were in line with the latest technological trends.

Lastly, further financial savings were realised by the client as we were able to reduce the NMD significantly. A decision which was made possible by studying the power quality data log, initially conducted at the beginning of the project. A further saving was realised as the Voltage Surcharge costs were now reduced from 12.75% to 10.5%.

Project: Tank Farm Lighting Upgrade

Project Engineer: Ashley Verhulp

Location: Klerksdorp

Year: 2018-2019

Decription:The electrical works associated with upgrading the lighting in the tank farm and surrounding areas, in accordance with SANS 10389-1: Exterior Lighting, Part1 - Artificial lighting for exterior areas for work and safety. The project successfully increased the lighting levels at all key areas in order to meet with the necessary requirements. The design was first modelled with 3D simulation lighting software before being implemented in phases. It incorporated LED lighting as far as practically possible and maximized the reflectance from the tanks to spread illumination evenly.
