From the President Dear Fellow Members: Since last reporting to you, I am pleased to advise you that an agreement has been executed with the Rotterdam Port Council for our 1998 convention. As part of the program, our Insurance Committee has virtually completed its program of a world overview. Commitments for speakers from Africa, Asia, Europe and, of course, the United States have been received. We are still searching for someone to present the American perspective. Among the social highlights of the convention is a scheduled lunch at the Rotterdam City Hall. More details including the probability of an address to be given by the Mayor of Rotterdam will be included in later articles and in our Journal of Commerce advertising program. We expect to have the most extensive social program ever scheduled, including a dinner tour of the Rotterdam harbor, which not only will be delightful but an excellent chance to socialize and network with your colleagues. On a less upbeat note, with regret I advise you that because of a reassignment of responsibilities at Hapag-Lloyd (America) Inc., Joe Carone has resigned as a Director of our organization. It is the Board's hope that, in the future, Joe shall rejoin us. However, his membership is still intact. We will miss Joe not only for his chairmanship of the insurance program, but for his insightful comments and guidance in matters that come before the Board. Personally, I'll miss seeing Joe at our monthly meetings. Good humor was always his hallmark. It will seem strange to proceed without Joe who has been a member and a Director from our initial meeting. We wish you all the best in your new position at Hapag-Lloyd (America) Inc. and look forward to your return to the Board. The new chair of the Committee is Monica Fekete of Brown, Sims Wise & White who has served as Co-Chair of the Insurance Committee. Ted Schroeder and Peter Vickers Co-chairs our Membership Committee, along with Executive Director, David Letteney, and have been hard at work to increase our membership both as to the number of members and the industries and interests they represent. If you know of anyone who would have an interest in joining our organization, particularly from the airline and trucking industries, we would be most please to contact them. If someone comes to mind, give Ted or David a call and one of them will follow up and make sure a membership application is in that person's hand. | ||||||||||||||||

Highway Weight Laws in the United States and the Transport Of Reefer Containers To and From Ports (Editor's note: This article was
suggested by an IRTA member. It is hoped that it fills a
need) Every country in the world with a road system more sophisticated than dirt paths has some means of regulating the weight and size of trucks using its streets and highways. When designing bridges engineers need to make assumptions regarding the gross weight of trucks, distance between axles and the number of heavy vehicles that will be on a bridge at any given moment. Pavement designers need the same information in order to develop specifications for substructure, optimum paving material and its thickness. In many countries, military considerations play a big role: Can the highway be used as an airstrip? What will be the weight of tanks traversing the highway? Among industrial countries, the United States has one of the most stringent set of highway weight laws and also one of the most confusing since, in addition to the Federal Bridge Formula applicable to the Interstate system, each state has its own laws and exceptions. This article can do no more than attempt to explain some of the peculiarities and exceptions that affect reefer container loading. Indeed, the best source of advice on how much cargo can be loaded into a reefer is your favorite drayman who, after all, runs the gauntlet of highway weighing stations and portable scale teams every day and is most familiar with local conditions. Moreover, the configuration of the container equipment tendered by the ocean carrier can make a difference in loading decisions. So, at the risk of telling you some things you may already know, here goes. The U.S. Federal Bridge Formula is a standard developed by highway engineers that relates a vehicle's gross weight to the spacing in feet between any two sets axles, the number of axles of the vehicle and the maximum legal load on each axle. The distance between axles is important because it affects the load-bearing capacity of a bridge. The U.S. maximum allowable gross weight is 80,000 lbs. The maximum allowed axle load is 12,000 lb. on the tractor steering axle, 20,000 lbs. on a single axle and 34,000 lbs. on a tandem axle. Thus, an 18 wheeler (one steering axle and two tandems) can carry 80,000 lbs. But wait. There's a couple of catches. A forty foot trailer or container does not have sufficient distance between the two tandem axles together with the steering axle to permit a full 80,000 lbs. gross. Moreover, it is virtually impossible to load any vehicle in a manner that will achieve the maximum axle weights of 12, 34 and 34 thousands pounds. We'll return to this in a minute. Now lets talk about reefer containers, chassis, tractors and generator sets. A 40 ft reefer will weigh between 9700 and 13,000 lbs., depending on whether it is of all-steel or aluminum and steel construction. A typical 40 ft chassis will weigh around 6700 lbs. Tractor weight can vary between 13,000 and 17,000 lbs. Then, there's the generator set. Is it mounted "clip on" fashion at the nose of the container or underslung under the chassis? A generator set with 50 gallons of fuel will weigh around 1500 to 1600 lbs. Some nose-mount gen sets equipped with 125 gallon tanks can weigh 2550 lbs. but these are generally intended for rail mini-bridge shipments. Thus, a 40 ft reefer, chassis, gen set and tractor can weigh between 31,000 and 38,500 lbs. For estimating purposes, 33,200 is probably a realistic figure. Now to determine the permissible cargo weight of this 33,200 lb. unit. It is not sufficient to merely subtract this number from 80,000 lbs. A typical five axle unit of this type would in theory have an allowable gross weight of 78,500 lbs. from the bridge formula tables. The steering axle load will be no more than 9500 lbs., reducing the cargo load by another 2500 lbs. Therefore, subtracting 33,200 lbs. from 76,000 lbs. we are left with a permissible cargo weight of 42,800 lbs. Once the packing of the container begins the weight distribution within the container becomes important. Each set of tandem axles should not be loaded beyond 34,000 lbs. This is nearly impossible to achieve if there is a nose-mount clipon generator set which will bear directly on the tractor tandem. Also, an attempt to balance the weight may interfere with uniform loading to achieve proper air flow. Then there are the exceptions to weight laws which various state legislatures have passed in order to attract exports through their ports. Several southern states have such exceptions and will allow up to 94,000 lbs. on trucks with proper permits. The ports of Oakland and Los Angeles/Long Beach have established "overweight corridors" so that heavily loaded reefers can travel between transloading and consolidation facilities and container terminals. However, none of these exceptions to state laws apply on the Interstate System. Federal authorities will not allow any variation from stated axle and gross weight limits. They insist that the states enforce them at weigh stations on the Interstates. This article has been slanted toward the exporter who needs to know conditions between his loading facility and the port. For the importer, a different set of conditions obtain. An import container may have been packed in a country with higher weight limits such as the European Union where 38 metric tons or 83,752 lbs. is permitted. Taiwan allows 97,570 lbs. under certain conditions. Other countries may not enforce weight laws at all and containers will be loaded to the maximum. The importer in the U.S. is faced with a real problem when his shipper overseas sends a container which, when mounted on U.S-style equipment, will exceed highway weights. He must decide whether to have the container stripped at the pier at a very high cost and possible prejudice to the quality of the cargo or risk a heavy fine by moving it to destination intact. Given sufficient warning of the overweight condition, the importer may be able route it through a port with an overweight corridor or one of the Southeast ports which have exceptions for heavy loads. To summarize: The importer or exporter should know the conditions under which his shipments are to move over the highway. The trucker transporting the load should be consulted in each instance and, where import loads are concerned, such advice should be sought before the shipment leaves the overseas shipper's premises.
ANATOMY OF AN UNUSUAL MARITIME
CASUALTY Master's Report to Owners: I write in haste in order that you will get this report before you form your own preconceived opinions from reports in the world press, for I am sure that they will tend to overdramatize the affair. We had just picked up our pilot and the apprentice was having difficulty in rolling the pilot flag up. I therefore proceeded to show him how and, coming to the last part, told him to "let go." The lad, although willing, is not too bright, necessitating my having to repeat the order in a sharper tone. The Chief Officer, overhearing this from the chartroom and thinking it was the anchors that were being referred to, repeated the "let go" to the Third Officer on the forecastle. The effect of letting the port anchor drop while the vessel was proceeding at full harbor speed proved too much for the windlass brake and the entire length of the cable was pulled out, "by the roots". I fear the damage to the chain locker may be extensive. The braking effect naturally caused the vessel to sheer in that direction, right towards a swing bridge that spans a tributary to the river up which we were proceeding. I rang up Full Astern but there was insufficient time for the engines to react. The swing bridge operator showed a great presence of mind by opening the bridge. Unfortunately he did not think to stop vehicular traffic. The result being that the bridge partly opened and deposited a Volkswagen, two cyclists and a cattle truck on the foredeck. In his efforts to stop the progress of the vessel the Third Officer dropped the starboard anchor, too late to be of practical use for it fell on the swing bridge operator's control cabin. Up to now I have confined my report to the activities at the forward end of my vessel. Aft, they were having their own problems. At the moment the port anchor was let go the assisting tug was tying up astern. The sudden braking effect of the port anchor caused the tug to "run in under" the stern of my vessel just at the moment when the propeller was answering my order of Full Astern. The prompt action of the Second Officer, in securing the line to the tug, delayed the sinking of the tug by some minutes, thereby allowing the safe abandoning of that vessel. It never fails to amaze me - the actions and behavior of foreigners during moments of minor crisis. The pilot for instance is at the moment huddled in the corner of my day cabin alternately crooning to himself and crying, after having consumed a bottle of gin in a time worthy of inclusion in the Guinness Book of Records. The tug captain, on the other hand, reacted violently and had to be forcibly restrained by the Steward who now has him handcuffed in the ship's hospital. I enclose the names and addresses of the drivers and their insurance companies of the vehicles on my foredeck, which the Third Officer collected after his somewhat hurried evacuation of the forecastle. These particulars will enable you to claim for the damage they did to the ship's railings. I am closing this preliminary report for I am finding it difficult to concentrate with the sound of police sirens and their flashing lights. Had the apprentice realized that there is no need to fly a pilot flag after dark, none of this would have happened. Signed, S. Sailbad, Master (AND ATTEND IRTA'S 4TH ANNUAL CONVENTION AND CONFERENCE, ROTTERDAM HILTON, MAY 17, 18 AND 19) |
