has announced that this opera- tion will commence in mid-1981, complementing its existing ferry service that already caters for passengers, cars, and light vans using vessels that do not require a specialist RO/RO berth. The Navire Cargo Gear link- span consists of a 70-meter-long roadway supported on twin pon- toons. In normal service, these pontoons are ballasted, allowing the whole structure to rest firmly on the specially prepared and lev- eled seabed. At most states of the tide, these pontoons are sub- merged although, during periods of very low tide, they will be ex- posed. However, RO/RO vessels should still be able to work cargo as the prepared area is at a high- er level than the harbor bed at the seaward end of the ramp. Should it be necessary to move the linkspan then the pontoons are easily de-ballasted, allowing the unit to be towed to a new lo- cation. This facility also eases the problem of maintenance, routine or otherwise. Navire Cargo Gear sees the possibility of further linkspans being constructed to de- signs similar to that of the Doug- las unit, especially for applica- tions where weather conditions make it difficult for simpler or more traditional designs to be employed. Douglas will be the sixth location to receive a Navire Cargo Gear linkspan. Others are in service in Scotland, Norway, Finland, Rumania, and the USSR. Navire Linkspan To Serve Isle Of Man RO/RO Operation Navire Cargo Gear has released an artist's impression (shown above) of the roll-on/roll-off link- span that will revolutionize trans- port between the Isle of Man and the U.K. mainland. The innova- tive design developed by Navire Cargo Gear, working closely with consultants Burness, Corlett & Partners, provides a roll-on/roll- off facility for Douglas harbor able to handle ships at all states of the tide. It is also able to with- stand the severe weather condi- tions that frequently produce wave heights of considerable mag- nitude, even within the harbor confines. Being built to the requirements of the Isle of Man Steam Packet Company, which is to start a freight RO/RO service between Liverpool and Douglas, the link- span is fully portable, and can be moved from location to location with the minimum of difficulty. Initially, it is to be positioned alongside the Red Pier at Doug- las, but at a later date it may be moved to the northside of King Edward VIII pier. The Navire shipyard in Finland is now fabricating the linkspan, which will be ready for towage to the Isle of Man in May. The Isle of Man Steam Packet Company has chartered a freight-only, roll- on roll-off ferry from P&W and $2-Million Federal Grant Awarded To Massport For Pier Renovation Congressman J. Joseph Moak- lev (D-Boston) has announced a federal grant of $2 million from the U.S. Department of Com- merce's Economic Development Administration to Massport to complete renovation of Boston's historic Fish Pier. At a reception at the Capitol, Congressman Moakley, who has championed the project since its start, de- scribed the Massport project as "a catalyst for revitalizing the New England fishing industry with substantial economic impact on the Massachusetts economy." Under the three-year modern- ization program, the 65-year-old waterfront landmark property will undergo a major facelift that LAGlin Vertical Machines (LEADING BUILDER OF CONVENTIONAL MILLING MACHINES) 6 Models Available Metric Machines Available NC Mills We do a better job selling and repairing propellers.

This project will make the Boston Fish Pier the number one fish processing center on the East Coast," he added. Phase One of the restoration project, completed in the fall of 1980, provided for exterior re- habilitation of the three buildings on the pier, while Phase Two, which will begin this year, will finance improvements to the pier itself, a new utilities and road surface as well as interior im- provements to the buildings. The overall three-year $12.5-million project will be completed bv April 1982. R.B. Bittner Named VP And Chief Engineer For Riedel International Robert B.
