Construction and engineering group Aveng Grinaker-LTA says its mechanical and electrical contracts division is making good progress on the electrical installation of nine harbour tugs, with work having started on the second and third tugs.
The first tug, the 31-m-long Mvezo, was launched in November, forming part of the Southern African Shipyards and Transnet National Ports Authority’s R1.4-billion tug-building programme.
The Mvezo is undergoing final fit-out and readiness for harbour and sea trials. The company notes that completion and handover of the last vessel was on time and schedule for the end of February 2018.
Aveng’s scope of work included procurement, commissioning assistance and attendance during harbour and sea acceptance trials at the Southern African Shipyards, in Durban.
Work also includes the supply and installation of marine-pattern cable ladder racks, support steel and watertight cable sealing penetrations, as well as the provision of all cable installation, glanding and termination materials.
Aveng Grinaker-LTA will further carry out the installation, termination and testing of all ships’ marine-approved electrical power, control, navigation and communications systems cables, as well as the installation of the main electrical switchboards and subdistribution boards and panels.
The team will also assist in commissioning all electrical power, control, navigation and communications systems.
