Aqua-Tech Diving Services, based in Durban, South Africa, offers a variety of different merchant shipping and civil services to the offshore industry. With experienced divers, we are able to offer timely solutions for your diving requirements and are available to attend to your requirements in all ports around South Africa.
With our sister company Divers Tech, we have expanded into northern Mozambique, Port of Nacala, where we have managed to gain exclusive permission to complete underwater hull cleaning and propeller polishing at outer anchorage.
We are also associated with many big firms in South Africa with regards to the surveying and maintenance of pipelines.
Aqua-Tech Diving Services offers hull cleaning services to the offshore industry, which includes the cleaning of the flat bottom, sides, grids, sea chests and rudder. It is a known fact that every dollar spent on a hull clean and propeller polish saves the company $8 in fuel. Our expertise in this field runs to over 1,000 vessels of all different lengths and drafts.
We are specialised in a mixed gas system that allows our divers to continue with a hull clean where the vessel is drafting over 12m. For these services the fees are slightly higher but it has been known that this system is effective and efficient.
During a propeller clean, all growth is sanded off first and then the disc pads are changed for polishing pads. Thousands of dollars are lost annually due to the inefficiency of the propeller. This can be caused by many things, including marine growth and mechanical damage, which can result in:
A smooth and properly polished propeller costs less to maintain, reduces fuel consumption by up to 10% and does not foul easily.
The Rubert Gauge Roughness Comparator has six roughness finishes that can be graded A – new propeller finish, and F – rough surface finish. We strive for grade A finish.
We offer a range of in-water surveys, including visual inspections, photographic surveys and CCTV surveys. Our experienced teams have the capability to handle every aspect of the underwater inspection process, producing detailed reports for a wide variety of purposes, including:
Class surveys can vary in detail and length depending on the requirements of the client. The degree of reporting depends on whether the survey is undertaken for specific months or for two or three years of a dry-docking extension period or instead of dry-docking.
We offer the following vessel inspection services: visual with photo documentation, closed circuit TV and video, and crack detection and definition.
Our ship repairs include kettle patches, crack arrests, blanking, sealing and cofferdams (small and large). The general underwater repair service includes the following:
Our range of pipeline services includes pipeline installations, pipeline surveys, and pipeline maintenance and repairs. In addition, we assist the large corporate plants with their fire reservoirs and clean water reservoirs.
We are available to help in berth extensions as well as in general survey work and the repair of quayside and underwater structures.
It is very important to take safety seriously when diving in contaminated waters. We are available to complete a safe dive in these types of waters as we have the correct equipment available for use.
