SEMINAR ON SHIP OPERATIONS — Attendees at the Seminar on Ship Operation in Heavy

Weather, held recently at Webb Institute of Naval Architecture, Glen Cove, N.Y. 11542. Lec- tures and discussions covered the latest developments in shipboard instrumentation to assist in optimizing ship behavior at sea and in weather routing procedures to minimize delays due to rough seas.

The Parcel Tanker Trades

The term parcel tanker has no precise meaning, but it is frequently applied to highly specialized ships designed to carry highly specialized liquid cargoes (which of- ten have severe hazards as regards toxicity, corrosiveness, inflammability, or a combina- tion of these, or which must be kept free from all contamination) in relatively small cargo lots, perhaps with a minimum of some 500 tons. In Study Number 58, a rather more liberal interpretation of the term par- cel tanker has been adopted, and all tankers of a greater sophistication than a conven- tional refined products carrier, and their

Norfolk Houston San Francisco cargoes, have been included, subject to a minimum size of 10,000 dwt. The minimum size enables the analysis to concentrate on inter-regional deepsea trades. In many ways, this is the most fascinating sector of the tanker market, containing not only relatively simple ships, but also those embodying the most advanced technology for transporting and handling bulk liquid cargoes. However, there is increasing pressure for international standards to be applied to the transportation of all dangerous liquids by sea, and this pressure is having a profound influence on the design and operation of parcel tankers.

After introducing the concept of the par- cel tanker and explaining the nature of some of the legislative/regulatory pressures on the owners and operators of these ships, the study moves on to identify cargo types and to analyze the main inter-regional move- ments of chemicals, solvents and vegetable oil cargoes on a matrix basis for the years 1973 and 1975. A comprehensive fleet analy- sis follows (by ship type, size, age and ma- jor operator) which allows comparisons to be made between the balance of supply and demand of ships for the historical years an- alyzed. Finally, some projections are made of the likely developments in the chemical trades up to the early 1980s and of the po- tential future supply / demand balance for parcel tankers.
