SOCIETA ESERCIZIO CANTIERI,

Viareggio ... ... SEC fosters radical change in build system

Ranking as a European leader in the construction of high-technolo- gy stainless steel chemical carri- ers, Societa Esercizio Cantieri (SEC) has raised its game both by taking on substantially larger tankers, and by moving into the field of advanced RoRo freight ships.

The common link in the two ele- ments of the company's business strategy is the adoption of a pro- duction system based on simulta- neous construction of sections of each ship at several sites along the

Ligurian coast, including

Viareggio, from where project con- trol is exercised.

The arrangements, contributing to a self-described 'Copernican' renewal of Italy's largest, private- ly-owned shipbuilder, have enabled SEC to increase its mar- ket scope beyond the previously 14,000 to 15,000 dwt maximum vessel size. No less important, the new system has enhanced its com- petitiveness in lead times and in execution of multiple-vessel pro- jects, and is expected to yield ben- efits in unit cost efficiency.

Thus, the first of the new breed of

RoRo trailerships ordered by

Swedish operator Stena is being constructed in three main sections at three plants: respectively at

Viareggio; at the ORAM yard premises in La Spezia purchased by SEC; and at Genoa, where it is involved in a joint venture with

GMG. The aft part of the ship is being built at Viareggio, where a slipway has been demolished to make additional space for the new process.

Joining of the mid-body from La

Spezia and forward section from

Genoa will take place in a 820 x 131-ft. (250 x 40-m) graving dock in the latter port.

Transportation of sections between the points of production will be effected using two specially adapted, 328 x 131-ft. (100 x 40-m) barges bought by SEC. To increase the company's operating flexibility still further, it has also obtained a site in Livorno harbor.

Delivery of the first of the 12,350- dwt Stena series, offering a trailer laneage of 2,705 m and a service speed of 22 knots, is anticipated in the latter part of 1997.

The step change in production and organization has extended

SEC's business potential to dou- ble-hulled tankers in the handy- size category, the immediate result of which has been the sealing of two contracts with domestic own- ers for an advanced new type of 22,500-dwt chem tanker.

The SEC Group, which absorbed the neighboring Benetti yard at

Viareggio in 1990, has significant experience in the field, having con- structed 32 chem tankers since 1972.

The new 22,500-dwt sisters for

Marnavi and Finaval constitute another stage in the development of specialized tanker technology, incorporating aspects of the

Greenchem concept developed by

SEC in mind of increasing envi- ronmental requirements.

One of the key features of the design is the adoption of a diesel- electric installation which will cover all shipboard energy needs including the propulsive power delivery for different operating modes up to a maximum service speed of 16 knots.

A while ago, SEC was disappoint- ed in its hopes of entering the fast
