  • Description

    Equipment ranging from one-man underwater scooters to huge underwater bulldozers, was on display when the second International Ocean Development Exhibition opened in Tokyo on Wednesday (October 4).

    Among the first visitors were nine observers from The People's Republic of China, who are attending the ocean development conference with which the display is associated.

    The one-man scooters can take an Qualung diver down to about 200 feet (about 60 metres) with a maximum speed of three knots. They are Japanese, like the underwater bulldozers. There are two types of bulldozer--one which operates in shallow water, the other is able to work the seabed up to a depth of around 200 feet (near 60 metres). The latter is operated by remote control through closed-circuit television "eyes", and its range of tasks includes levelling the seabed for plant cultivation. its makers are now developing underwater borers and dredgers, which will be operated in similar way.

    Another underwater gadget looks rather like a helicopter. It carries two "aquanauts" to a depth of about 160 feet (??? metres) where they can emerge for about four hours' underwater exploration. the "submersible" can be driven a long way underwater, making it a useful exploration vehicle.

    A heavy-duty device from Canada, called "Pisces", enables scientists to work in shirt-sleeves at depths of around 6,500 feet (2,000 metres). It has a robot arm at the bow which can collect rock or plant samples.

    A United States company is showing an off-shore survival capsule, which they think may replace conventional life-boats on ships, particularly oil tankers. It is already used on oil rigs and drilling platforms, and it can be launched from a single davit in 30 seconds. The capsule holds 28 people and, having its own oxygen supply, engine, food and water, offers full protection from water, fire and fumes. A version for conventional ships should be available by the end of the year.
