The bow is in the form of a pair of hydraulically operated pincers that open to scoop effluent into a skip on the vessel's deck via a pulverising unit located in the hold. Water drawn in with the effluent is filtered through a series of grills before being oxygenated and then ejected through the stern.

The refuse skip is positioned amidships forward of the cabin for easy removal by crane and the 9 tonne steel vessel is designed for transportation between harbours on a special low-load trailer.

Main propulsion power is a Perkins Sabre M215C, while auxiliary power for the hydraulics and a firefighting and wash-down hose located at the stern is from a Perkins Sabre M85T.

The turbocharged and intercooled 6 cylinder, 6 litre M215C develops 225hp at 2,500rpm and gives the Pelican a top speed of up to 10 knots with the pincers closed. When these are opened for dredging, this is reduced to between 0.5 and 3 knots. The turbocharged M85T is a 4 cylinder, 3 litre engine producing 85hp at 2,600rpm.
