ment. A construction diver may also wear a light frog suit in inspection dives, for example. The maintenance and servicing of equipment and machinery is also an es- sential part of construction diving activities. Dressing properly for the different seasons is also important. “Whatever the season, the basic prin- ciple is that the diver should not get too cold or hot. In addition to technical layers, a woollen garment may be worn under the diver’s dry suit, so even in six-degree water in winter they manage OK. The only challenge in winter is freezing equipment, which must be avoided. In the summer, on the other hand, the surface waters can be really warm, so sweat comes easily as they work,” Baltic Divers Ltd’s Teleni. “A construction diver’s equipment also includes breathing gas tubes. The surface crew monitor the gas supply, and under- water working hours are strictly specified according to diving systems in compliance with safety standards. The breathing gas contains oxygen and nitrogen. In shallow waters, the working time can be up to two hours at a time, but at deeper levels, such as 15 metres, the working time is, accord-

ing to safety regulations, 70 minutes. The breathing gas can, of course, be enriched with oxygen, in which case the working time under water can be extended. Con- versely, a diver must surface to take hours- long breaks between dives in order to re- move nitrogen from the bloodstream and avoid the diver’s sickness, ‘bends’,” says Divecon Ltd’s Venemies. CHARACTERISTICS OF A DIVER Less than 20 or so professional divers grad- uate each year, of which only a few end up as construction divers. The work is mentally and physically demanding, but with the right attitude it is also rewarding.

“A good construction diver wants to de- velop and succeed in his work. With effec- tive teamwork and increasing experience it is rewarding to be able to deal with all kinds of challenges that confront you. Ulti- mately, a satisfied customer is the greatest thanks a construction diver can receive,” says Teleni. “Good construction divers are character- ised by their use of common sense, a cool disposition and team spirit. And challenges are overcome daily with good humour – it’s the right attitude to take,” concludes Ven- emies.

A CONSTRUCTION DIVER’S HELMET is a technically complex device. It includes a diving phone as well as illumination and recording equipment. Surface personnel can monitor the diver’s work with the aid of a display monitor. IN ADDITION TO TECHNICAL LAYERS, a woollen garment may be worn under the diver’s dry suit, so even in six-degree water in winter they manage OK.
