A pontoon is used on a river to transfer materials to a barge.The pontoon is constructed from high density polyethylene and has amass of 40 tonnes. The dimensions of the pontoon are 19 m long x10m wide x 0.75m high.
a) What is the freeboard of the pontoon when it is floating inthe river?
b) What additional mass (tonnes) can the pontoon carry if amaximum draught of 0.45m is available?
c) If the additional mass is to be carried as sand (density1600kg/m3) in a container 6 m long and 5m wide, how deep a layer ofsand can be carried? If instead of sand, the pontoon is to carrybentonite at a density of 2600kg/m3, what depth can be carried?
