Deck Machinery Review (continued) parts and service capabilities and maintains complete microfilm files of original equipment drawings to provide replacement parts that ex- actly match original specifications. Replacement parts, service and up- grades for Pine Tree Engineering Co. manufactured equipment are available as well. Hyde also offers deck machinery overhaul and refur- bishing services. Experienced Hyde service personnel perform installa- tions, repair and overhaul work worldwide. In recent years, the Korean Navy has installed Hyde steering systems, anchor windlasses and capstans on a total of 29 frigates, corvettes and other naval vessels. Several addi- tional ROK orders are pending. The steering systems supplied for 22 ROK corvettes include an electronic control system which eliminates the conventional differential control system. Hyde recently received an order for the steering gear on a new oiler to be built in Taiwan. Hyde manufactured the anchor windlasses and several types of Re- fueling at Sea winches for the USS Wasp (LHD-1) and is currently building the same equipment for LHD-2 and -3. Hyde is also actively involved in many commercial and Navy projects, including upgrading GEMS Level Switches for Shipboard Service. Where high reliability is required for monitoring liquid levels and signaling alarms. There's a GEMS switch to meet all types of marine liquid level applications...to monitor and control levels, signal alarms, and to provide oil/water interface. Ideal for use with diesel engine fuel tanks, lube oil reservoirs, ballast, bilge, or oil sump tanks or for other common shipboard uses. 1= •f 58000 Series Single or Multi-Level Switches. Custom-made switches, using standard components, are supplied with various mounting methods, lengths, floats, materials, etc. to suit the application. Externally Mounted Switches. LS-35565 (brass)/LS-56060 (stainless steel). For use where access to inside of tanks is limited, such as on lube oil or fuel day tanks. Custom-length housings. Provide ease of maintenance and tank cleaning Slosh Shielded Switches. For corrosive or turbulent liquids. Made entirely of CPVC plastic, these low-cost switches are supplied with either mounting holes or NPT mount- ing. Suited for bilge level indication, slosh tanks and other leak detection locations. Compatible with seawater, many fuels, and hydraulic and lube oils. With Intrinsic Safety. Zener Barrier Safe-Pak relays, FM approved, from GEMS provide intrinsically safe operation when interfacing level switches with your AC or.DC loads.

IMO DELAVAL Circle 225 on Reader Service Card 16 Circle 19 on Reader Service Card Imo Delaval Inc. offers a wide range of liquid cargo-handling equipment through its companies and divisions. The IMO Pump Division of Imo Delaval Inc. has introduced a verti- cal deepwell barge pump designed to unload and strip liquid cargo tanks carrrying heavy pertoleum products at the rate of 1,500 gpm. In addition to #6 fuel oil and asphalt, the positive displacement pump can handle products as light as #2 heating oil. Designed for use on new installations, refits and con- versions, the new pump provides performance for all variations of cargo characteristics and dockside piping arrangements. The Gems Sensor Division of Imo Delaval Inc. offers two liquid level subsystems which provide reliable liquid level indication where closed loading of shipboard cargo is a re- quirement. The two subsystems—a Dipstick Liquid Level Indicator and a Self- Checking Level Switch—provide important "see, hear and feel" fea- tures for tankermen, barge opera- tors and other ship personnel re- sponsible for safe, accurate and reli- able bulk transfer of cargo. The Gems Dipstick Liquid Level Indicator is a compact, entirely self- contained liquid level indicating unit, designed primarily for use in storage drums, vats and tanks. It is excellent for "on-the-spot" level readout applications when electrical power is not available. The Gems Self-Checking Level Switch provides a unique method of confirming, from outside the tank, the operational integrity of all vital components of the self-checking lev- el switch. The level switch was designed specifically for use in closed-loading crude and fuel oil tankers, chemical and other product carriers. A new Hydraulic Liquid Cargo- Handling (HLCH) system for use on board chemical and product tankers has been introduced by IMO AB, an Imo Delaval company. A complete system for cargo han- dling, the HLCH system is designed for dry installation on product tank- ers as well as crude oil tankers. Flows of 1,200 m3/h per pump at a maximum of 120 mlc can be reached. The system allows remote control as well as local control. Additional functions can also be connected to the hydraulic system, e.g.—bow- thrusters, winches, fans, deck cranes and various types of pumps for slop tank, ballast, tank cleaning, fuel oil and emergency unloading.
