Ice Tech '81 (continued from page 36) which are expected to be of com- mercial importance during the re- mainder of this century, their lo- cation, quantity, physical charac- teristics and the market location to which they must be shipped.

Three potential marine transpor- tation systems are described in detail.

Paper No. 5—"Technical Devel- opment of An Environmentally

Safe Arctic Tanker" by B. John- asson, A. Keinonen, B. Mercer and J. Stubbs.

SYNOPSIS: Following Dome Pe- troleum's Arctic research and de- velopment experience, the overall safety criteria are introduced for an environmentally safe non- spilling Arctic tanker design.

Safety in ship/ice interactions and the prevention of major ice impacts by new remote sensing technology are addressed.

Paper No. 6 — "Development and Implementation of Ship Ice

Certificates" by D.D. Maksutov and Yu. N. Popov.

SYNOPSIS: Annual growth of cargo traffic and the lengthening of the navigation season in the

Arctic demand a large number of cargo and research vessels suited for ice navigation. Because of the possibility of ice damage, each ship should have an "Ice Certif- icate" containing information which ensures the fail-safe oper- ation of the ship. This paper de- scribes the background and re- quirements for "Ice Certificates" in the USSR.

Paper No. 7 — "Arctic Marine

Shipping Route Evaluations" by

D.F. Dickens.

SYNOPSIS: Recent studies have attempted to refine our under- standing of winter shipping con- ditions, particularly in dynamic areas such as the Beaufort Sea.

This paper uses several recent

Arctic shipping route evaluations as case studies, and attempts to isolate those ice characteristics considered amenable to a reliable statistical treatment, and relevant to vessel designers and operators.

Paper No. 8—"A Ship Transit

Model for Passage Through Ice and Its Application to the Labra- dor Area" by R.J. Gill, A. Aboul-

Azm, B. Terry and W.E. Russell.

SYNOPSIS: A transit time com- puter model for passage through pack and continuous ice is de- scribed, and the results of its ap- plication to offshore Labrador and

Lake Melville are discussed. The model uses ice conditions which are digitized along specific routes and outputs total transit time for passages at various times during the ice season.

Paper No. 9 — "Ice Conditions

Affecting Navigation in the Beau- fort Sea" by B.D. Wright and

D.L. Schwab.

SYNOPSIS: In this paper, quan- titative data on ice conditions in the Beaufort Sea are presented which include the distribution of ice type, floe size, undeformed ice areas and pressure ridge height, frequency and orientation. The data presented are currently be- ing used in the design of offshore production systems for the Cana- dian Beaufort Sea.

Paper No. 10 — "A Rational

Basis for Hull-Ice Strengthening

Criteria" by Capt. J.L. Coburn,

A. Nawwar and J.B. Montgomery.

SYNOPSIS: Several classification societies and various government regulations provide guidelines for strengthening of ice-transiting ships. However, there are incon- sistencies among these different guidelines, and ships have suf- fered hull damage from ice while operating in zones for which they were supposedly strengthened ad- equately. This paper reports on the results of a study to develop the basis for rational selection of ice-strengthening criteria.

Paper No. 11—"On the Struc- tural Analysis of Ice Transiting

Vessels" by P.C. Xirouchakis and

R. Stortstrom.

SYNOPSIS: This paper develops a methodology for a rational se- lection of ice-strengthening cri- teria for ice-transiting commer- cial ships so that the scantlings of structural members can be de- termined. The method predicts the load carried by each trans- verse bulkhead, the maximum bending moments developed in

Session 1: Operations and

Commercial Aspects

Regular Ro-Ro freight services and the problems of their membership or association to freight agreements (panel discussion)

The operation of a high- speed Ro-Ro service between Seattle-Tacoma and Alaska

The use of flat rack and platform containers on

Ro-Ro ships. The advantages and hazards of working these types of 'specials' in the Ro-Ro mode

Session 2: Ro-Ro Ship

Types and Design Features

The planning and design of a new concept of large

Combination Ro-Ro carriers now under construction (Joint Paper)

Forest products Ro-Ro's in the Eighties; cargo mix and flow patterns; new designs and economic criteria

Combined stabilization

Anti-Heeling Systems and their influence on Ro-Ro vessel and Ferry Design

Session .'i: Ro-Ro Ferries and Short-Sea Routes

The emergence of the super-jumbo ferry has brought extra demands on the capability of their Ro-Ro access and internal rolling agreements. A ferry forum will discuss their concept, realisation and service experiences.

Session 5: Ro-Ro Safety

Since the 1980 Conference, when major shipowners and designers gave their views on the stability of Ro-Ro ships, much attention has been focussed on recent accidents involving this type of tonnage. For this reason,

Ro-Ro 81 will again include a Safety Session on different aspects.
