Russian Ship started in September 1994. First loading and offloading locations were surveyed. A structural model of the unloaders was prepared for the strength analysis of the unloaders subjected to the inertia loading dur- ing transportation.

Various seafastening scenarios were analyzed and the optimum con- figuration was selected.

The Stakhanovets Ermolenko departed on Jan. 9. During the voyage, the maximum experienced roll motion was on the order of 13 degrees in a 15-second roll period, well within the design limits of the seafastenings. Weather was favor- able and the transport went smoothly. On Jan. 25, the ship arrived at the anchorage of Huasco,

Chile.

In February 1995, two ship unloaders were safely delivered to the refurbished Guacolda pier in

Huasco, Chile. The unloaders were shipped fully erected by Trinav Ship- ping (Barbados) Ltd., using the Rus- sian heavy lift ship Stakhanovets

Ermolenko. Argonautics Marine

Engineering of Sausalito, Calif., provided all the engineering and supervision required for the safe load-out, seafastening, transporta- tion and offloading of the unloaders.

The two Paceco Corporation-de- signed luffing type ship unloaders were built by Sade Vigesa at the

Verolme yard in Angra dos Reis,

Brazil. Each unloader measured approximately 51.5 ft. x 33 ft. (15.7 x 10 m) with a total height of ap- proximately 170.6 ft. (52 m). Total shipping weight was 465 tons.

The transport engineering

Dockwise Transports MHI Cranes

Using New Bracing System

Dockwise NV, which says it is the op- erator of the largest fleet of semi-submers- ible heavy-lift vessels in the world, success- fully moved two fully-erected post-Panamax container cranes on board the Dock Ex- press 11, using a new, reportedly cost- effective bracing system.

An unusual feature of this transport is that the cranes were shipped without any welded diagonal steel bracing pipes.

Due to the good seakeeping character- istics of the Dock Express type of vessel, the forces acting on the cranes due to the motion of the ship in a seaway are report- edly much lower than the forces acting on a barge. This enables the cranes to be braced by a system of tensioned wires in- stead of massive welded steel bracings. This method results in considerable cost savings for the crane builder.

Both cranes were builtby Mitsubishi Heavy

Industries (MHI) in Hiroshima.

The Dock Express 11 leaving the port of Hiroshima with a cargo of two fully-erected post-Panamax container cranes bound for Hong Kong and Yantian, China, braced with tensioned wires. The red painted gooseneck crane is destined for the MTL Terminal in Hong Kong. The blue painted crane with its boom upright has been delivered to the new terminal in Yantian.

Westport Shipyard To Deliver Alaskan Explorer1

Kenai Fjord Tours, which hosts day excur- sions out of Seward, Alaska, to Kenai Fjord

National Park, will take delivery of a new 100-ft. (30-m) boat built by Westport Shipyard, Inc. of

Westport, Wash., this spring.

Randy Rust, general manager of Westport, announced that his company will build theA/as- kan Explorer, designed to operate off the coast of the Kenai Peninsula in Alaska. The 149-passen- ger, U.S. Coast Guard-certified vessel will be licensed for coastwise service.

Designed by Jack Sarin Naval Architects of

Bainbridge Island, Wash., the vessel will be based on the 100 x 22.6-ft. (30 x 6.9-m) Series 9500 high-speed hull, which has been tank tested to 45 knots. However, powered by 3512 DITA (Continued on page 25)
