ACS Bulk Carrier Safety Jpdate The International Association of Classification Societies (IACS) is accelerating completion of the :argo hold element of its Enhanced Survey program. As a result, all pre-1987 bulk carriers of 492 ft. (150 m) in length or greater and classed by IACS members that have not been through an Enhanced Special Survey by January 1, 1997, will have to com- plete the cargo hold survey ele- ment of this survey before January 1, 1998. This deadline will ensure completion of IACS checks on all relevant vessels approximately 12 months earlier than expected, when the Enhanced Survey Program was implemented in 1993. Acceleration of cargo hold sur- veys is one measure detailed by IACS in its extensive submission on bulk carrier safety initiatives to the May meeting of IMO's Maritime Safety Committee. Other unified requirements con- cerning bulkhead and double bot- tom strength in a hold flooded con- dition, hatchcover strength and side shell and frame construction are being evaluated. For existing ships, IACS is also evaluating other options including possible upgrades based on new- building requirements, or an alter- native of homogenous rather than alternate hold loading of heavy cargoes. Permanent Secretary James Bell said that IACS' main objective is to develop a "unified, comprehensive and realistic approach to improving structural survivability." He added that IACS is seeking practicable means for reduction of risk from structur- al failure to the existing bulk fleet, and setting high safety standards for the design of new bulk carriers. GHH Borsig Established Following the approval of the German Federal Cartel Office, MAN GHH of Oberhausen and DBB of Berlin have established GHH Borsig. The new company encompasses the worldwide activi- ties of both enterprises in the field of turbomachinery. Corporate leadership is with MAN GHH, who holds a majority share of 75.1 per- cent. The new company is part of the MAN Group, with a product range covering turbocompressors, gas and steam turbines, turboex- panders and process-gas screw compressors.

To date, Hitachi Zosen has received a total of six orders for single hull VLCCs from Golden Ocean. These are the first two double hull VLCCs ordered by the group. The newly ordered VLCCs are Hitachi Zosen standard type ves- sels, reportedly capable of carrying 2.2 million barrels of crude oil safe- ly and economically. Hitachi MAN B&W 7S80MC type diesel engines will be used as their main engines. These VLCCs will be built at the Ariake Works, which has built var- ious types of vessels since it began operations in 1973, including a total of 31 VLCCs and ULCCs.

Railko's composite bearings are specific for rudder, stabilizer and steering gear applications, and in the stern/tube propeller shaft as- semblies. The bearings are report- edly able to continue to work at full power in sea-water, in the event of a seal failure.

Our Autoship systems have speeded up our work - and they let us use all of our knowledge, experience and creativity to develop the design that best meets the needs. How do we do it now? Once we've optimized the ship numerically, we design the hull form in Autoship. It's a full NURBS-based 3-D modeling program and it's automatically faired. Throughout, we can check hydrostatics and resistance on-line with Autopower. That saves us a lot of time, and we use it to look for extra speed. Next, we define all the tanks and compartments in Autohydro. Calculating volumes and balancing the ship is easy and quick, so we can spend more time to optimize the layout. We define the structural members in Autobuild; the program automatically checks for interference and generates a bill of materials and a complete list of weights. That eliminates manual drafting, saves the yard manhours, and reduces the usual worry about weight. To save even more, we can export direcdy to NC cutting machines, radically reducing lofting and nesting costs. Yes, all these programs come from the same place - Autoship Systems, the world's largest developer of Windows™-based marine software. With Autoship, the entire design process, from concept to cut plates, is a smooth, seamless flow. Autoship helps us produce better designs, faster, with lower construction costs...benefits you appreciate, and our competitive edge! Gain the competitive edge!
