Lamor's GTA pumps for harvesting seaweed

Aquaculture

Seaweed has been an important local food source in South Asia for generations. One innovative seaweed farmer in the Maldives had an idea to use Lamor’s GTA pumps to increase his production.

Seaweed, sometimes called sea vegetables, is an ancient food in South and East Asia. Recently it has become a trendy superfood all over the world, thanks to its flavour and nutritional properties.

 

The old way to harvest seaweed for food is for divers to swim to the sea floor and cut the plants by hand. The plants either float to the surface on their own or need to be carried, where they are collected on board a vessel.

 

This method is slow, inefficient and in some cases dangerous for the divers. A seaweed farmer in the Maldives wanted a better solution and contacted Lamor to find out the options together.

Lamor’s GTA pumps are submersible Archimedes screw pumps. They were developed with the idea of being a multi-purpose pump to be used in oil spill response activities, emergency offloading of oil, tank cleaning, pipeline maintenance or sludge removal. However, the Maldives entrepreneur and Lamor wondered if these versatile pumps could be used for harvesting seaweed. This was not in the engineers’ minds when they designed the GTA pumps, but they soon realised this could be a perfect application.

 

The pumps’ smooth pumping action and easy flow was created to not emulsify oily water, but it also wouldn’t damage fragile seaweed. The compact pumps were constructed with light, seawater resistant aluminium – weighing from 25-49 kilos (55-108 lbs.) – and could be easily manoeuvred by divers on the sea floor. The GTA pumps have a cutting knife fitted on the inlet in order to slice ropes or other debris in oil spills, but that knife could also cut seaweed.

The Maldives seaweed farmer was able to dramatically increase his productivity and efficiency by using a Lamor GTA pump. Safety was also improved, as divers didn’t have to remain submerged for such a long time.

"The GTA pumps were designed with the high criteria required for emergency response operations, but these qualities also made the pumps perfect for other applications we never even considered originally, like harvesting seaweed."
