The LPG vessels were received following their over 8,000 nautical mile journey from China. All four vessels were positioned close to each other on the same ship, ready for ro-ro transportation onto dry land.
In conversation with the client, ALE elected to use two 2-file, 20-axle PSTs to load-in the LPG vessels. This decision was taken to enhance the cost-effectiveness of the project, as PSTs could cover the required road, rail and gravel terrain while still maintaining a pace in line with the wider project schedule.
A few months prior to the move, ALE utilised its Route Survey Tool to analyse the many obstacles between the port and the installation location. This tool attaches to the roof of the survey vehicle, logging points of interest so that the ideal transportation route can be planned, and time outside the vehicle minimised during execution.
Using this data, the 60m long LPG vessels were transported across a 3.1km route from port to site. The chief obstacle in their path was the Richards Bay Coal Terminal railway lines.
The delivery trains travelling on these lines are essential to the operation of the Richards Bay Coal Terminal; any disruption to deliveries would have a severe impact on the export of coal.
To ensure smooth passage, ALE staff attended induction training on site at the terminal, and worked in close contact with local traffic management staff to minimise disruption. Having crossed all rail lines, the LPG vessels arrived at their installation location.
ALE was able to mobilise equipment worldwide – in this case moving skidding equipment from Spain to South Africa – to allow transportation and installation to take place together. Four 500t skid shoes were used to move the vessels approximately 30m to their final positions.
This project will allow LPG to be imported into South Africa in much greater quantities, circumnavigating a low domestic supply and allowing the country to seriously consider more environmentally-friendly power generation. The facility is planned to be operational during 2020.
