Setting Out & Topographical Survey at the Freeport of Monrovia, Liberia
THS Concepts were appointed by Pharos Marine to undertake an existing survey of 2 navigation towers and the setting out/realignment of the towers, which had been built incorrectly. The Freeport of Monrovia is an important freight terminal in Liberia, West Africa. The problem was that the existing towers had been built at an incorrect angle. As a result, the ships travelling in would have had to travel through the port's breakwater which obviously could not happen. The navigation tools were so flawed that no ships entered the port at night! Chris and Tom surveyed the existing, incorrectly-built towers. They were approximately 8 degrees off of the line they should have been on. 8 degrees may seem like insignificant, but the port stretches 1.5 km so it equated to a big error. We assisted with the new building work and orientated and level the tower base, before leaving the Liberian contractors to finish the foundations.
