Case study – Tanganyika Explorer

Surestream strives to collect the most accurate and effective data possible. And often this requires an innovative approach.

This is exemplified by our redesign of a fishing research vessel in Lake Tanganyika to acquire seismic and lake-bed coring and environmental monitoring through water samples.

The challenge

The boat had been built for fisheries research which was ABS to design and there were issues with its stability. Therefore we have devised a creative way to solve this.

To provide additional stability we are fitting sponsons to the vessel that project either side of the hull, which will to provide an environmental and operational benefit.

Environmental benefit

Part of the refit will include the installation of a water treatment system which will ensure that all water discharged from the vessel complies with MARPOL (International Convention for the Prevention of Pollution from ships) regulations.

There will be an oil and water separator installed in the bilge to prevent any accidental discharge of fuel oil or lubricants.

All dry waste will be separated and compressed prior to recycling onshore.

A bespoke refueling system will be installed for the support boat to prevent any spillage of diesel oil. In addition, the space inside the sponsons will provide additional fuel storage alleviating the requirement to refuel the vessel on the lake.

Competitive edge

There is currently no other boat on the lake equipped for seismic surveying and Surestream will be the first to shoot seismic since the 1980s.

The Tanganyika Explorer will have a 3km seismic streamer and a seismic source consisting of two clusters of three guns generating 500 cubic inches.

The addition of the sponsons will increase the rear-deck working area by two meters and improve the vessel’s overall stability. These will also be modified to carry 50% extra fuel which increases the vessels endurance.
