A cheap, easily made and disposable method of containing oil spills has now been developed by a Swedish designer, Captain Erling Blomberg. It is available in forms suitable for both coastal and deep sea use. The coastal barrier, known as Trelleborg Red Eel, consists of interlocking sections of double PVC plastic sheeting 60 cm wide. At close intervals along this are welded pockets filled with a small amounts of ballast sand below wedge- shaped cellular plastic bodies acting both as supports and floats. The pockets are sealed with double stapling. The wall floats steadily in the water with two-thirds of its depth submerged. Captain Blomberg has made two further developments to this system for ocean use. The first is the Vinga Sweeping Boom for collecting spilt oil from the sea surface. In this case the boom has a deeper wall with flexible glass fiber laths, and is formed into a triangular sweep with a funnel collecting point for the oil. This boom is towed between two tugs. The Wreck Boom intended to surround a ship involved in a collision or grounding where damage to oil tanks occurs, is constructed on the same principle as the coastal and sweep booms, but with strengthened plastic walls which have a tensile strength of 5000 kg.
