ACTU-VATOR:

Folding Hatch Cover Innovation From The Main Deck, Inc.

RCCL Orders Second, $300-Million

Ship From Kvaerner Masa-Yards

Royal Caribbean Cruises Ltd. (RCCL) exer- cised its option to order a second 1,950-passenger cruise ship from Kvaerner Masa-Yards of

Helsinki, Finland. The ship is scheduled for delivery in September 1997 and will cost about $300 million.

RCCL currently has a 1,950-passenger ship on order with Kvaerner-Masa, for delivery in No- vember 1996. RCCL has committed itself to fleet expansion through new construction to approxi- mately $ 1.2 billion through 1997, making it one of the largest shipbuilding programs in the cruise industry's history.

AMSC In Agreement With Sprint

American Mobile Satellite Corp. (AMSC) signed a distribution agreement with Sprint Cellular, which provides wireless voice and data service to more than 750,000 customers. As a distributor of

AMSC's Skycell mobile satellite services for use in the maritime industry, Sprint Cellular will be able to offer comprehensive availability of mobile communications service regardless of location throughout the U.S. once the service begins in 1995. AMSC holds the Federal Communications

Commission license to construct and operate a mobile satellite service which will complement the existing terrestrial cellular system, provid- ing mobile voice, fax and data communications in all areas not covered by cellular.

The Main Deck, Inc. has designed a new type of folding hatch cover that may be fitted at both weather deck and tweendeck hatchways. In its simplest form, this type of hatch cover consists of two, flat-topped panels, similar in basic construc- tion to those currently in use and driven by hydraulics, but completely self-contained inside the hatch cover. Adjacent panels are hinged together so that they fold. The panel at the stowage end is hinged to a plinth, welded to the deck. Mechanical actuators, gearbox, drive shaft, pillow block bearings and electric motor are con- tained within the cover. The mechanical actua- tor unit designed for the system is reportedly very safe to operate, inexpensive and durable for a shipboard environment.

Components

Reportedly, parts and equipment of the ACTU-

VATOR system are relatively inexpensive, and due to the system's simplicity, repairs can be performed by ships personnel in port or under- way. The ACTU-VATOR lifting system is a simple arrangement consisting of the following components: • Electric Motor. Five-hp, coupled to accept a 2.25-inch stainless steel drive shaft. The motor is controlled by a hand-held control unit, attached to a flexible cable, plugged into the coaming or convenient receptacle, outside the cargo hold.

The control unit is attached to an electric cable, lengthened to suit. • Motor Drive Shaft. 2.25 in., stainless steel, supported midway by a pillow block bearing, running on to the gearbox. • Gear Box. Transfers power from the single, incoming drive shaft to a trans- verse drive shaft used to power the mechanical actuators. • Mechanical Actuator. Trans- fers power from the transverse drive shaft, creating a lifting movement as the screw moves forward and a closing move- ment as the screw retracts. • Yoke. Installed at the end of the actuator screw. The oppo- site end of the yoke is pinned through the cam action hinge assembly, which is attached to the hatch cover at the break point. Different configura- tions of various designs can be incorporated into cargo access openings. For a larger appli- cation, the size of the actuator and drive shaft would be en- larged, and the number of ac- tuators and the rated hp of the electric motor would be in- creased. Different types of gear

The Main Deck's new ACTU-VATOR hatch cover system can reportedly be operated by one person. reducers can be introduced to maximize power configurations. All the drive system's compo- nents are attached to the underside of the hatch cover panel. All drive mechanisms are held in place by brackets welded to the underside of the top panel and supported by cross beams. This places the drive system out of harm's way and out of the elements.

The ACTU-VATOR drive mechanism is a posi- tive locking system, so unless the motor is en- gaged and the drive system energized, the covers will not move. This design feature reportedly prevents covers from free falling. For emergency operations such as a power failure, a manually operated ratchet assembly is incorporated into the drive train. The Main Deck claims ACTU-

VATOR hatch covers can be operated virtually by anyone who is capable of operating the hand controls (open/close), and there is no need for more than one operator. The covers can report- edly be stopped in an instant in the event of an emergency. Applications for the ACTU-VATOR system include, but are not limited to, ship's cargo hatch covers on coamings and ship's cargo hatch flush hatch covers in the weather and below decks; barge cargo hatch covers; shipboard aircraft hangar covers; large stores hatches; single section stern, bow ramps and side port ramps; ship's interior ramps; bow, stern and side port door openings; submerged door openings for tor- pedo tubes and missile launch tubes; large ship- board doors in bulkheads and deckhouses; inland waterway lock gates; and shore side facility doors — horizontal, inclined or vertical.
