Turkey is a key market for us for the maritime sector. Ship owners, operators, managers, marine surveyors, marine fire servicing companies all thrive in the country, especially around the key hub of Istanbul. Captain Erol has known Coltraco Ultrasonics for years and has been successfully promoting our range of ultrasonic ship survey and inspection products. Below are photos of his company Tuna Ship Supply headquarters based near Tuzla shipyard.

Marine servicing companies looking to offer ultrasonic watertight integrity tests as part of their service often need to comply with the IACS rules. Hence they will be looking for equipment complying with these.

One leading solution is used for testing watertight integrity of hatch covers on bulk carriers, ensuring water ingress is not a risk factor by identifying leak sites as small as 0.06mm. Cargo damage is one of the most prevalent claims for P&I Clubs. So customers choose Coltraco’s Portascanner WATERTIGHT to quickly and easily test hatch cover tightness. It is more accurate than traditional high pressure hose testing and is cleaner because there is no water run-off. It is more reliable than traditional chalk testing also.
