Improved Outlook

Into Next Decade Seen

By Canadian Shipyards

The Canadian Maritime Indus- tries Association, which represents

Canada's shipbuilding, ship repair, offshore and ocean industries, re- ported in its 1987 annual statistical report that the "outlook through 1988 into the next decade appears promising."

Several new contracts were awarded in this year's first quarter, the reported noted, and Canadian yards expect further contracts from the government and fisheries for new vessels or refittings and repairs this year. Naval contracts are also pending, the association said.

The association also cited reports of "significant" new hirings of em- ployees since the beginning of this year.

Omnithruster Waterjets

Offer Maneuverability

In Polar Regions —Literature Available

Omnithruster bow and stern thrusters installed aboard one of the

Soviet Union's newest research ves- sels are providing excellent are ice management and maneuverability, according to the Santa Fe, Califor- nia-based company.

The 7,600-dwt Akademik Fedor- ov, operating in the harsh ice condi- tions of the Antarctic, is fitted with

Omnithruster bow and stern thrust- ers. The 1,300-kw aft Omnithruster unit, a model JT 1700, delivers a thrust of about 12 tons at 493 rpm and can propel the ship forward at about 3 knots and at lower speeds in other directions. The system sucks water from underneath the keel and directs the thrust in the required direction by steerable nozzles.

Some of the basic concepts of high velocity waterjet ice manage- ment were devloped by the presi- dent of Omnithruster, C.M. Aker.

Some of those primary concepts in- clude the use of a specially designed intake to reduce or virtually elimi- nate ice ingestion, the development of special shaped and positioned nozzles to deflect ice chunks that would otherwise impinge upon the ship's propellers, and the evolution of a two-phase flow air/seawater mixing device for ice lubrication, without the use of air compressors.

The Omnithruster auxiliary propul- sion system has also been redesign- ed to enable it to operate in ice regimes utilizing actuators and shock-absorbing devices combined with means of freeing ice in the actuating vanes, so that operation of the system is possible utilizing not only side thrust, but fore and aft auxiliary propulsion as well.
