Berg Propulsion CPP System Operation & Service Manual – 710 HX/4 HDX-40 Controllable Pitch Propeller

Description

Berg Propulsion CPP System – 710 HX/4 HDX-40 Operation & Service Manual

This is the complete operation and service manual for the Berg Propulsion controllable pitch propeller (CPP) system built around the 710 HX/4 propeller and HDX-40 pitch control unit. The document was issued for the equipment delivered under Order No. 5211 (New Bldg. No. DY611) and gathers every technical section needed to run, maintain and overhaul the CPP installation from the propeller hub through to the bridge control panels.

Chapters Covered

• 1 Technical Specification — propeller and hub, tail shaft and intermediate shafts, hydraulic system
• 2 Propeller & Shaft — HX propeller description, operation, maintenance and repairs, removal and disassembly, installation and re-assembly, mounting of propeller hub, tail shaft and stuffing boxes, blade screw torque table
• 2.2 Propeller shaft and oil pipes — description and operation, removal and disassembly
• 2.3 Lubricating system — description, filling, oil recommendations for propeller hub H/HX
• 2.4 Couplings — description, mounting instruction, dismounting instructions
• 2.5 Appendix — drawings and part lists (shifting arrangement, propeller hub assembly, propeller shaft assembly, intermediate shaft assemblies, lubrication of sterntube and hub)
• 3 Accessories — sterntube seals (IHC Supreme), sterntube bearings, journal bearing (Renk-Radius LRLPW21-205), bulkhead passage gland (Type ND Seal 73090), shaft earthing device, shaft locking device, net cutter
• 4 Hydraulic System — pitch control unit type HDX, oil distributor, pressure oil system, oil recommendations, emergency control and pitch blocking, hydraulic pumps (Denison PV/PVT series), drawings and part lists
• 5 Remote Control System ERC3000 — general description, bridge and engine room control panels, command transfer, manoeuvring, backup control and pitch indication, load control, parameter setting and fault diagnosis, clutch control and shaft speed indication
• 6 Supervising System — propeller system alarms and alarm setting list
• 7 Spare Parts — ordering information and recommended spare parts
• 8 Special Tools — blade screw spanner, leading member spanner, OMC coupling mounting equipment, shaft nut spanner

Across these sections the manual documents the mechanical build of the HX propeller hub, the hydraulic piston and leading member mechanism that converts linear piston travel into blade rotation, the oil pipe feedback arrangement inside the hollow-bored propeller shaft, and the oil distributor that feeds pressure oil to the cylinder. It also carries the wider installation: the tail shaft and intermediate shaft assemblies, the OMC oil pressure coupling procedure, the sterntube seals and bearings, and the ERC3000 PLC remote control system with its parameter menus and alarm codes.

What You Can Do With This Manual

With this CPP system manual on hand a chief engineer or yard technician can check and top up the propeller hub lubrication by the fill-and-spill method, torque the blade screws to the correct figure from the blade screw torque table, remove and refit individual propeller blades without dismantling the whole hub, and strip the hub cylinder and leading member assembly for inspection. It supports the flange coupling drive-up and dismounting procedure with the correct diameter increase checks, and gives the sterntube seal alignment, built-in length and run-out tolerances that must be met before launch. For the hydraulic side it covers the HDX-40 oil distributor, the manoeuvre valve arrangement, working pressure and relief valve settings, and the emergency hand pump take-home device. For the electrical side it walks through ERC3000 control transfer, combinator and constant speed modes, load control parameters, and the alarm setting list.

Why Correct Procedures and Specs Matter Here

A controllable pitch propeller is a closed hydraulic system with tight tolerances — blade root bearing clearances, hub oil fill levels, blade screw torque and coupling drive-up diameter are all values that cannot be guessed. Getting them wrong risks blade damage, hub oil loss or a coupling that will not release when you need it to. This manual supplies the actual figures and step sequences for the 710 HX/4 and HDX-40 configuration rather than generic guidance, which is what makes it worth keeping on board.
