Small but Flexible

Shoalbuster Baloe

With a length of 23 meters, Shoalbuster “Baloe” is the smallest vessel in our fleet. With a draft of minimum 2,10 meter and a bollard pull of 22-ton, she can operate flawlessly without any problems in the shallow waters.

Shoalbuster “Baloe” has proven herself time after time to work without any problems in the dredging, offshore wind farm support, civil marine construction, surveying, and oil & gas industry. With three hydraulic pins installed on the aft, the safety for crew and vessel is optimized while anchor handling. And with a hydraulic crane fitted to the vessel, she can do lifting operations without any problems within the limitations.

For ploughing operations, an A-frame can be installed and both A-frames as ploughs are owned and operated by Herman Senior.
