WORLD/Ballast ­ A new study by Lloyd's Register of Shipping raises serious concerns for the safety of most existing vessel types and configurations using the sequential method of ballast water exchange.

Many of the ballast conditions for the 26 ships used in the study indicated invariably that there was insufficient longitudinal strength, draught forward, propeller immersion and bridge visibility.

The report "Lloyd's Register Study On The Sequential Ballast Water Exchange Method" has just been released by Lefteris Karaminas, principal surveyor, advanced studies group, research and development department at Lloyd's. It comes at a time when West Coast states and B.C. ports are promoting ballast water exchange as a stop-gap measure to prevent the introduction of aquatic nuisance species.

The International Maritime Organization currently recognizes the sequential and the flow-through methods of ballast water exchange. In the former, a ballast tank is emptied and filled, usually in mid-ocean, the theory being that any harmful organisms will be flushed out in the exchange. However, as Karaminas points out, pumping and piping systems undergo an increased workload, and it requires careful planning to lessen the risks imposed on the ship. These risks include longitudinal strength, dynamic loads, excessive trim, bottom forward slamming, propeller emergence, intact stability and bridge visibility.

"If ballast exchange operations on existing ships, especially those utilizing the sequential method, are carried out without understanding or controlling the risks, then the ship's safety could be endangered," Karaminas said in an interview.

He suggested the shipping industry starts looking for feasible solutions acceptable to all parties concerned ­ administrations and operators, in particular. "The study describes various options to mitigate the risks which could be imposed by the sequential method. . . Solutions should not be imposed, but be part of a selection process which, at the end of the day, will satisfy the needs of the administrations and still be practical for the operators."

Karaminas said that the study serves as a reference document for administrations who intend to develop ballast water management policies.

The study began last October, testing 26 ships in both light and heavy ballast conditions, using the sequential method for all ballast tanks. These vessels comprised three single skin tankers, one double skin tanker, four double hull tankers, four single side skin bulk carriers, five containerships, two liquefied natural gas carriers, two self-discharging bulk carriers, three oil-bulk-ore carriers and two general cargo ships.

Apart from containerships, most cases caused propeller emergence. Some of the other dramatic results cover longitudinal strength, i.e. permissible still water bending moments, shear forces and cargo torque. The study showed:

* All single skin tankers and oil-bulk-ore carriers indicated insufficient longitudinal strength.

* Some double hull tankers indicated insufficient longitudinal strength.

* Single side skin bulk carriers indicated that longitudinal strength could be sufficient only in the light

ballast condition.

* One of the two self-discharging bulk carriers indicated insufficient vertical bending strength.

* Containerships and liquefied natural gas carriers indicated sufficient longitudinal strength.

* General cargo ships indicated sufficient longitudinal strength only in the ballast arrival condition.

WASH./Intertanko ­ Washington State is figuring out what to do next, now that the U.S. Supreme Court has struck down some of its tough oilspill prevention rules.

"We're still evaluating the decision," said Stan Norman, from the state's Department of Ecology, the day after the March 6 court ruling. He said the state hoped to get some specific interim guidelines out to planholders shortly. In a unanimous decision, the justices ruled that four key parts of the state's tanker regulations were pre-empted by federal law. These covered imposing general navigation watch procedures, English language skills for

crew members, training and maritime casualty reporting requirement. For example, the state requires tankers to put a third watchman on deck in periods of bad visibility and to have at least one deck officer who speaks English.

The justices said federal laws pre-empt states from setting their own standards to prevent oil spills from tankers -- except to address "peculiar" local conditions. The ruling basically ends a long legal dispute between the state and Intertanko, the International Association of Independent Tanker Owners. Justice Anthony Kennedy ordered the remaining parts of the regulations be sent back to the federal trial judge so that their validity could be reassessed "in light of the considerable federal interest at stake." These include requirements setting maximum crew work hours, drug and alcohol-testing policies, operating procedures and personnel policies.

Harry Hutchins, executive director of Puget Sound Steamship Operators Association, is pleased with the court's decision, and surprised by the consensus and range of the ruling. He said, to give the state its due, when it first brought in the regulations ­ tougher than the federal laws enforced by the U.S. Coast Guard ­ the Coast Guard hadn't caught up with them. Now though, the Coast Guard has caught up, and the state's are unnecessary, he said.

However, Washington's Attorney General Christine Gregoire said the ruling strikes a terrible blow to Washington's Puget Sound protection, and called on the U.S. Coast Guard to strengthen its tanker regulations.

The tanker industry and federal government were supported by 15 foreign governments and a variety of shipping and business groups. Twenty-one states and territories and many other organizations supported Washington's case. The ruling may affect laws and regulations already on the books in 12 other U.S. states.

U.S./Emissions ­ A lawsuit filed on behalf of an environmental group seeks to compel the U.S. Environmental Protection Agency to regulate air pollution by large ocean-going vessels serving U.S. ports.

The lawsuit was filed in the U.S. Circuit Court on Feb.24 by Earthjustice Legal Defense Fund, on behalf of the Bluewater Network. It seeks to compel the EPA to create strong emission standards for large ocean-going vessels, claiming they impose a significant smog burden on U.S. port cities.

ALASKA/Emissions ­ The EPA issued violation notices five days later against six cruise lines operating in Alaska last summer, claiming 13 of their ships violated air pollution laws.

Notices of Violation were issued to Holland America Line, (operating the Nieuw Amsterdam, Statendam, Veendam and Westerdam); Princess Cruises, Inc. (Dawn Princess, Sea Princess, Sun Princess); Celebrity Cruises, Inc. (Galaxy, Mercury); Norwegian Cruise Lines, Inc. (Norwegian Dynasty, Norwegian Wind); Carnival Cruise Lines, Inc. (Jubilee); and World Explorer Cruises. Inc. (Universe Explorer).

The EPA said these 13 ships fouled the air in Juneau, Seward and Glacier Bay, at times emitting smoke that significantly exceeded state and federal limits for visible emissions. The companies have 30 days to respond to the notices and the opportunity to meet with the EPA before any further action is taken.

John Hansen, president of the North West CruiseShip Association, said the EPA's actions were discouraging, as the agency used information the cruise lines had gathered themselves as part of a program to ensure high levels of environmental performance. He said the notices contributed little to cooperative discussions now under way between industry and government officials, looking at ways of reducing air and water pollution.

WASH./Pipeline ­ The U.S. Department of Transportation's Office of Pipeline Safety (OPS) has ordered Olympic Pipe Line Co. to modify its internal testing and inspection plans before OPS will allow Olympic tothe section of pipeline closed after an explosion in Bellingham in June 1999. Three people died after the pipeline ruptured, spilling 277,000 gallons of gasoline and subsequently exploding in Whatcom Falls Park, Bellingham.

ALASKA/Oil ­ If Valdez's planned tanker tax goes ahead, the state could lose about $2.4 million in royalties and severance taxes for next year's budget, the House Transportation Committee heard in March.

The City of Valdez's gain would be at the expense of the state, the Anchorage Daily News reports. However, the loss would be offset within a few years. The tax would increase the oil industry's cost of transporting crude to the Lower 48, thus decreasing royalties and severance taxes paid to the state. In November, Valdez City Council unanimously passed an ordinance after watching its tax base decline along with the diminished value of the trans-Alaska oil pipeline and tanker terminal. Oil and gas industry officials are strongly opposed to the planned tax.
