Supply for steering gear, hatch covers, deck machinery brakes, controllable pitch propellers and radio remote control systems.
Vessel Core supplies technical buyers with spare parts for steering gear, hatch covers, deck machinery brakes, controllable pitch propellers, and the radio remote control systems met on cranes and deck machinery.
Deck equipment reaches a parts counter through a name, and on this family the name is the weak point. Ownership moved under the plate on one machine, a yard fitted its own name to another, the plate on a third changed when two brake houses merged, and the maker of a fourth supplies modular units that share one model name across different builds. A request naming only the maker tends to come back with questions. A request quoting the plate as it reads, and saying which sub-assembly is wanted, usually does not.
Commercially useful spare parts supply coverage for survey preparation, deck machinery overhaul and steering gear inspection findings. Maker names and type codes appear on this page only to identify the equipment on board: Vessel Core holds no dealership, distribution, representation or partnership agreement with Kawasaki, MacGregor, Pintsch Bamag, Scanreco, Tenfjord or any other manufacturer, and does not present itself as holding one.
The rotary vane actuator on a spherical rotor is Tenfjord's core design, built the same way across four generations of the lineage, and actuator seals, bearing pads, distribution valves and feedback units are the lines that recur. A plate reading Rolls-Royce or Ulstein Tenfjord rather than Tenfjord is the same machine under a later ownership name, so it is worth quoting the plate exactly as it reads rather than correcting it to the name in use.
Kawasaki offers RV, RM, RE, FM and FE types, a lineup descended from the Hele-Shaw type of 1925 through the BV and LV types to a 2024 Unified-Edition E-series that builds the control box and rudder angle indicator into the actuator. That is a supply fact before it is a catalogue fact: on the newer series those arrive as part of the actuator, on the earlier ones they do not, so the generation decides whether the control box is a separate line at all. Actuator and pump assembly components, seals and control box internals are the recurring lines.
Kawasaki has built controllable pitch propellers under licence from Escher Wyss since 1956 and the current line is the CH Series. The pitch mechanism is worked by a hydraulic unit built into the propeller assembly, with a gearbox-mounted oil distribution box offered on some installations. One maker name therefore covers two mechanically separate product lines, and a request naming only the maker needs one clarification before it moves: steering gear or propeller.
A side-rolling hatch cover is one system built from three parts — panels, the rolling and cleating hardware, and the hydraulic drive — and the cargo carried, not the cover itself, decides which of the three wears first. A MacGregor request that names the cover but not the cargo leaves out the half of the context that points at the wearing item.
The KFB brakes are spring-applied and electromechanically released, fitted as safety brakes on deck machinery drives. The SFB series is the one long used on winch motors in shipbuilding and as service or holding brakes on crane installations, and it exists in a seawater-resistant execution, which the KFB description does not mention. Linings or brake shoes, the release unit, springs, pins and bushes are the items on a Pintsch Bamag line, and the marine execution belongs in the request because the corrosion protection changes the parts.
The RC 400 systems are met on hydraulically driven cranes and deck machinery, and a replacement is paired to the receiver already fitted rather than simply ordered by model. G2 and G2B receivers are supplied with proportional and digital outputs and with a CAN interface, and several can be linked in a master and slave arrangement. Transmitter housings, joysticks and levers, membranes, battery packs and chargers, and the receiver cards are the recurring Scanreco lines.
Three of the makers on this page carry the same difficulty in three different forms. A Tenfjord plate may read Rolls-Royce or Ulstein Tenfjord after the ownership moved. A hatch cover plate may name a builder other than MacGregor outright, since these covers are supplied and serviced under several yard-fitted names. A brake reached for as Pintsch Bamag is usually plated Pintsch Bubenzer, because the two brake houses merged. None of that stops an enquiry. It only means both names belong on the same request rather than one of them being quietly corrected into the other.
Deck machinery is an assembly of separately identified pieces, and the request is read against the piece rather than against the ship it is bolted into. A brake is quoted from its own type plate rather than from the winch it sits on. A receiver is read against the output type and the valve it drives, because one ordered on the model name alone can arrive with the wrong interface. A Mini transmitter is identified by its function count, which is why a front-panel photograph is asked for ahead of the rest of the request. Name the sub-assembly wanted and the machine it belongs to, and the two together usually settle the drawing.

42 models · 16 notes
| Model | Series | Maker | Typical parts |
|---|---|---|---|
| BCP hubs · feathering | Controllable pitch propellers | Berg Propulsion | BCP, for Berg Controllable Pitch Propeller, is the hub name under which Berg launched a feathering design that works inside its standard hydraulic hub, with pitch running from full astern through full ahead to feathered, and later offered the option across its BCP hubs. On twin-screw ships one propeller can be feathered while the vessel runs on the other shaft. Say in the enquiry whether the propeller documents mention BCP or feathering. |
| MTA series | Azimuth thrusters | Berg Propulsion | Berg's steerable thruster, with a controllable or fixed pitch propeller, often in an integrated nozzle. The Z-drive takes a horizontal input shaft from an engine or a motor; the L-drive takes a vertical input shaft from an electric motor. Berg names tugs, ferries and offshore vessels as its usual applications; gear sets, bearings, shaft seals and steering seals as the recurring lines. |
| MTT | Tunnel thrusters | Berg Propulsion | Bow and stern transverse thrusters with fixed or controllable pitch, driven by an electric motor, a diesel engine or a hydraulic motor, and built in modular form so that key components can be exchanged as units. Propeller-shaft seals, gear and bearing parts and, on controllable pitch units, hub seals recur. |
| MPC800 | Propulsion control | Berg Propulsion | Berg's marine control system for its propellers and thrusters, on a redundant dual-processor architecture with interfaces to joystick, autopilot, DP and VDR. Where the panel on board does not show MPC800, a photograph of it settles more than a guess at its name. Control modules, panels and levers are the lines it brings. |
| FU | Tunnel thrusters | Brunvoll | CP or FP tunnel units in L- or Z-drive: propeller shaft seals, blade seals, replaceable blade bearing liners, pitch mechanism and hydraulic parts. |
| FW … R · LowNoise FU | Resiliently mounted tunnel thrusters | Brunvoll | Resiliently well-mounted units and LowNoise double-tunnel units; the LowNoise type shares the FU letters, so state the double tunnel. |
| RDT | Rim driven tunnel thrusters | Brunvoll | Permanent magnet rim drive with no gearbox, shaftless or with a central shaft: motor and drive items. |
| AR | Retractable azimuth and Combi thrusters | Brunvoll | Lifting actuator seals, locking devices, azimuth brakes, stem sealing box and bearing housing; say whether the unit is the Combi. |
| AUP/AWP · PU | Propulsion azimuth thrusters | Brunvoll | Push-ducted and pull-open units, weld-in or bolt-in: shaft and blade seals, blade bearing liners, pitch and steering items. |
| BruCon · Saia PCD | Thruster control | Brunvoll | Controller modules, bridge levers, indicators and pitch feedback units; give the PLC type from the open cabinet. |
| CPC-AF · CPR-AV · CPR-AH · CPC-AR | CPP · A-type Series | Kamome | Kamome's controllable pitch propeller for small and medium-sized ships. The hub is split into fore and aft sections and the blades sit between them, a layout the maker describes as easy to overhaul and reassemble. CPR-AV and CPR-AH carry a built-in reduction gear on a different axis, CPC-AR on the same axis. |
| CPC-BF · CPR-BV · CPR-BH · CPC-BR | CPP · B-type Series | Kamome | The series for medium and large-sized ships, built on a solid hub with each blade assembled individually. Kamome's customer service states that on a CPP it can replace a single blade, so a damaged blade is an enquiry in its own right rather than a reason to price a whole propeller. Reduction-gear builds follow the A-type pattern: CPR-BV and CPR-BH on a different axis, CPC-BR on the same axis. |
| TCB-35 — TCB-270 | Side thruster · controllable pitch | Kamome | A tunnel thruster with a controllable pitch propeller, released in 2004: thrust direction is changed by pitch alone, with no reversing mechanism, and the drive can be an engine, an electric motor or a hydraulic motor. The catalogue section names the parts a buyer meets: blade, propeller hub, piston, guide block, oil distribution, cylinder, compact seal, spherical roller thrust bearing, gear case, propeller shaft and driving shaft. |
| TFA-06 — TFA-110 | Side thruster · fixed pitch | Kamome | A fixed pitch thruster of simple construction; Kamome states that only the seal in the rotating part needs regular replacement. Drive by engine, electric motor or hydraulic motor. With no pitch mechanism, enquiries centre on that seal, the gear set, the bearings and the drive. |
| Compact Seal CX · DX | Oil-lubricated stern tube seal | KEMEL | Kobelco's lip-ring seal for oil-lubricated stern tubes, built in CX and DX types and fitted as an aft seal against the sea and a forward seal against the engine room. Several seal rings sit in line inside the seal casing and run on a chrome steel liner. Seal rings, liner, casing O-rings and gaskets are the recurring docking lines, and the type letters on the plate decide which ring set applies. |
| Air Seal AX | Oil-lubricated · air type | KEMEL | The air-type aft seal of the same oil-lubricated range, run with an air supply from the ship. Rings, liner and the air control items are quoted together, and the plate or the seal drawing shows whether an AX seal or a Compact Seal is fitted at the stern. |
| MODEL XL | Controllable Pitch Propeller | Nakashima Propeller | The CPP model for large vessels. The hydraulic cylinder sits inside the outboard propeller hub and moves the blades directly, and proportional control valves allow fine pitch corrections such as Automatic Load Control. The hydraulics are doubled: normal and emergency control valves, and separate pumps for main and auxiliary pitch control oil. A request should say which circuit an item belongs to. |
| MODEL XS | Controllable Pitch Propeller | Nakashima Propeller | The CPP model for medium and small vessels. The pitch cylinder sits in the inboard intermediate shaft; oil from the hydraulic unit passes a solenoid valve into the OD box, then a pilot check valve, and the piston turns the blades through the pitch rod and crosshead. The hub interior is lubricated with grease instead of oil, which is worth stating on any hub seal request. |
| MODEL NT-F · TFN types | Tunnel Thrusters | Nakashima Propeller | Fixed pitch tunnel thrusters designated NT-F005 up to NT-F130, with the TFN-15S to TFN-75S types listed in the same range. Nakashima has built tunnel thrusters since 1976. The unit can be withdrawn from the hull for overhaul ashore, and its propeller shaft seal is the same type the maker fits as a main propulsion stern tube seal. |
| MODEL NT-C · TC-70N | Tunnel Thrusters | Nakashima Propeller | Controllable pitch tunnel thrusters from NT-C010 to NT-C130, plus the TC-70N type. A high-performance filter in the gravity oil tank keeps the oil clean, and the remote-control unit at the bridge console has a touch-panel display. Nakashima also offers low-noise blades for ships such as research vessels and special shaft seals for ships with large draught changes; state either on the enquiry. |
| ECO-Cap · JET-CAP · Monster Package | Boss caps and stern devices | Nakashima Propeller | Propeller boss caps that break up the hub vortex. ECO-Cap carries thin FRP blades on a copper alloy cap body; JET-CAP carries GFRP fins bolted to a bronze boss cap screwed onto the shaft nut, and a damaged fin can be replaced on its own. The Monster Package combines further flow-improving devices, among them the Ultimate Rudder Bulb and the Neighbor Duct, whose geometry Nakashima works on with Becker Marine Systems, a group company since 2021. |
| Shaft Horsepower Meter · NASCA | Shaft monitoring | Nakashima Propeller | The Shaft Horsepower Meter, developed by group company Shoyo Engineering, uses a detection ring on the intermediate shaft, an electromagnetic induction unit and a processing and display unit; a shaft thrust load meter can be added. NASCA (Nakashima Ship Cruise Assist System) builds speed, shaft power and fuel consumption monitoring on top of it. Name the unit, not just the system. |
| KFB series | Spring-applied electromechanical brakes | Pintsch Bamag | The KFB brakes are spring-applied and electromechanically released, fitted as safety brakes on deck machinery drives. Linings or brake shoes, the release unit, springs, pins and bushes are the items, and the brake is quoted from its own type plate rather than from the winch it sits on. |
| SFB series | Spring-applied electromechanical brakes | Pintsch Bamag | The SFB brakes are the series long used on winch motors in shipbuilding and as service or holding brakes on crane installations, and the series includes a seawater-resistant execution. State whether the marine execution is fitted, since the corrosion protection changes the parts. |
| SC 30T | Tank cleaning machine | Scanjet | A Scanjet tank cleaning machine type. Give the type exactly as marked and photograph every serial on the machine; a nozzle, gear or seal for an SC 30T is matched to those, together with the nozzle size if it is known. Without a serial the line stays open until one is found. |
| SC 90T2 | Tank cleaning machine | Scanjet | A separate Scanjet type. Copy the full designation, digits and letters, because an SC 90T2 and an SC 30T are different machines and no nozzle, gear or seal passes from one to the other by assumption. Send the serials and the nozzle size if known. |
| RC 400 | Radio remote control systems | Scanreco | The RC 400 systems are met on hydraulically driven cranes and deck machinery, and a replacement is paired to the receiver already fitted rather than simply ordered by model. Transmitter housings, joysticks and levers, membranes, battery packs and chargers, and the receiver cards are the recurring lines. |
| G2 · G2B receivers | Receivers | Scanreco | The G2 receivers are supplied with proportional and digital outputs and with a CAN interface, and several can be linked in a master and slave arrangement. State the output type and the valve it drives, because a receiver ordered on the model name alone can arrive with the wrong interface. |
| Mini transmitters | Transmitters | Scanreco | The Mini transmitters are modular, supplied with linear levers or with joysticks and additional buttons and switches, so two units with the same name can have different controls. Photograph the front panel and send it with the request; the function count is what identifies the unit. |
| SRP RudderPropeller | Azimuth propulsion units | Schottel | Fully steerable unit that makes a rudder superfluous; SRP-U and SRP-D variants. Propeller shaft seals, gearbox bearings, bevel gear sets and steering drive items. |
| SRP-R · SRP-RT | Retractable azimuth units | Schottel | Retractable RudderPropeller; the RT variant works as a transverse thruster when retracted. Seal, gearbox and steering items per serial. |
| SRP 1515 | Older SRP designation | Schottel | Schottel's own pages give the SRP 460 as the type formerly called SRP 1515. Send the designation as stamped with the serial; both names belong on one request. |
| SRE EcoPeller | Electric azimuth units | Schottel | Azimuth unit developed for an electric drive, LE-Drive available. LeaCon seal items, gearbox bearings and steering drive parts. |
| STP TwinPropeller | Twin-propeller azimuth units | Schottel | Two co-rotating propellers on one underwater unit. LeaCon seal items, DuroVario clutch parts, gearbox bearings. |
| STT TransverseThruster | Tunnel thrusters | Schottel | Fixed pitch across the range, controllable pitch on part of it. Shaft seals, gearbox bearings, CP hub seals and hydraulic items. |
| SPJ PumpJet | Flush-mounted pump-jets | Schottel | Installed flush with the hull behind an inlet grid. Seal sets, gearbox items and inlet grid parts. |
| SCP ControllablePropeller | Controllable pitch propellers | Schottel | Shaft-line CP propeller, full-feathering optional. Hub seals, pitch mechanism and hydraulic items, stern tube seals. |
| SRT RimThruster | Rim-driven thrusters | Schottel | Electric thruster with no gearbox or shaft, water-lubricated bearings. Stator, rotor and bearing items; no gear-oil lines. |
| RV · RM · RE · FM · FE types | Steering gear | Kawasaki | Kawasaki's current steering gear lineup, descended from the Hele-Shaw type of 1925 through the BV and LV types to a 2024 Unified-Edition E-series that builds the control box and rudder angle indicator into the actuator. Actuator and pump assembly components, seals and control box internals are the recurring lines. |
| CH Series | Controllable pitch propellers | Kawasaki | Kawasaki has built controllable pitch propellers under licence from Escher Wyss since 1956; the current line is the CH Series. The pitch mechanism is worked by a hydraulic unit built into the propeller assembly, with a gearbox-mounted oil distribution box offered on some installations. |
| SS · SL · TS · TL · SP types | Electro-hydraulic steering gear | Tokyo Keiki | The current type list: SS is the standard form, SL carries an independent auxiliary steering hand pump, TS has the auxiliary steering built into the steering stand, TL has both, and SP is a main steering gear in two systems. A leading W, F or H marks a wider hard-over rudder angle and an M after the type letters a higher rudder speed, so HSLM and SL are one family in two executions. Requests concern solenoid valves and coils, pump and hand pump seals, and hose sets. |
| S/T · UN/TN/UP · MP/MU/MT · HMT/HMU | Earlier hydraulic steering gear | Tokyo Keiki | The maker's list of discontinued marine products files its earlier steering gear under the autopilot each was supplied with: UN, TN and UP types for the PR-1000 Series, MP, MU and MT for the PR-1500, HMT and HMU for the PR-1600, and the S and T types, together with SS, TS, SL, TL and SP types without a closing S or R, for the PR-2000. All are shown as no longer maintained, and for the PR-2000 types the list names the current types for the PR-3000 Series as the successor. |
Wear patterns, duty context and plate-reading advice from the maker pages. They help scope a request; they are not designations.
| Topic | Context | Maker | Detail |
|---|---|---|---|
| Controllable Pitch Propeller | Controllable pitch propellers | Berg Propulsion | Berg's main-shaft propeller, the blades turned in the hub by hydraulic pitch control, for diesel-mechanical and diesel-electric plants. The hub circulates its oil with integrated moisture monitoring, and that one oil both lubricates the hub internals and carries the pressure that moves the blades. Blade seal kits, hub components and pitch hydraulic items are the recurring lines. |
| Fixed Pitch Propeller | Fixed pitch propellers | Berg Propulsion | Berg also builds fixed pitch propellers for steady-load operation. With no pitch mechanism in the hub, the hub-oil and pitch-hydraulic items do not apply, and the recurring lines move to the shaft line: stern tube bearings, the stern seal and their gaskets. |
| Power packs and control gear | Hydraulic systems | Hatlapa | Pump unit plate, working pressure and circuit drawing reference are the starting point. Seal kits, filter elements, relief and directional valve parts are the usual scope on these requests. |
| Rotary vane steering gear | Steering gear | Hatlapa | Rotor and stator size designation, rated torque and system pressure identify the unit. Requests usually concern vane seals, bearing bushes, hydraulic pump parts and control valve components. |
| Windlasses and mooring winches | Deck machinery | Hatlapa | Type plate, drive arrangement, hydraulic or electric configuration and brake band details are needed. Common items are seal kits, brake linings, gearbox bearings, clutch parts and hydraulic motor components. |
| Fixed pitch propellers · keyless · high skew | Fixed pitch propellers | Nakashima Propeller | Main propellers made as a single piece for the ship they were designed for, from tankers and container ships to passenger tonnage. Nakashima developed keyless propellers in 1971 and its high skewed propeller in 1981; current designs add tip rake and the minimum blade area NHV (Non-Hub Vortex) propeller. Requests cover a replacement propeller to the original drawing, repairs of bent or eroded blades, the propeller nut and the boss cap. |
| Provision crane | Ship stores and spares | OPCO | OPCO's provision cranes lift ship stores and machinery spares aboard. A provision crane works in short, frequent lifts at the side of the ship, so slewing, hoisting and limit items wear together. Send the crane plate, the SWL plate as it reads and the parts-list page with the item numbers. |
| Hose handling crane | Tanker cargo hoses | OPCO | On tankers the hose handling crane lifts the cargo hoses to and from the manifold. Hook, rope and brake items on such a crane are load-bearing and follow the crane's certificate; hydraulic items are read against the power unit that drives the crane. |
| Deck crane | Cargo and general lifting | OPCO | OPCO also builds deck cranes for cargo work. A deck crane is quoted from its own plate and parts list; nothing is carried over from a provision crane list on the strength of a similar part name. |
| Oriental Precision & Engineering or OPCO on the documents | Maker identity | OPCO | Both names belong to the same Busan company, and the documents of one crane may use either. Send them exactly as written; the crane type, the serial number and the item numbers decide the part, not the form of the name. |
| Pintsch Bamag or Pintsch Bubenzer on the plate | Maker identity | Pintsch Bamag | Buyers reach for the Pintsch Bamag name, while the brake and its linings are usually plated Pintsch Bubenzer after the two brake houses merged, so both names belong on the request. Send the type plate, the disc or drum arrangement and whether the release unit or only the linings are needed. |
| Nozzle housing · gear | Spare items | Scanjet | Nozzle housings, often supplied with their gear and pin, and loose gears are the items that come up for these machines. Each is matched by machine type, serial and nozzle size. Seals go on the same request from the parts list for the type and are checked against the liquid the machine washes with. |
| Scanjet · Alfa Laval | Maker identity | Scanjet | Machines and their manuals carry the Scanjet name. Alfa Laval acquired the company in 2022, so newer paperwork may show either name. With the machine type, either is enough to start a request. |
| Tenfjord rotary vane | Spherical rotor steering gear | Tenfjord | The rotary vane actuator on a spherical rotor is Tenfjord's core design, built the same way across four generations of the lineage. A nameplate reading Rolls-Royce or Ulstein Tenfjord instead of Tenfjord is the same machine under a later ownership name. Actuator seals, bearing pads, distribution valves and feedback units are the recurring lines. |
| Side-rolling hatch cover | Panel, cleat and hydraulic set | MacGregor | A side-rolling hatch cover is one system built from three parts — panels, the rolling and cleating hardware, and the hydraulic drive — and the cargo carried, not the cover itself, decides which wears first. The plate may name a builder other than MacGregor outright; that does not stop the enquiry, since these covers are supplied and serviced under several yard-fitted names. |
| TOKIMEC on the plate | Maker identity | Tokyo Keiki | Founded in Tokyo in 1896 as a pressure gauge works, the company began building gyrocompasses in 1918 and hydraulic equipment in 1954, and its own history records Japan's first marine autopilot in 1926. It traded as TOKIMEC from 1990 and restored the Tokyo Keiki name in 2008, so a plate reading TOKIMEC is the same maker. Send the type code as stamped; it reads the same way under either name. |
Nothing matches. Send the designation from the plate — we also quote items that are not listed here.
This list indicates coverage. It is not stock on hand and not a claim of affiliation with any manufacturer.
Part numbers are helpful, but the plate as it reads, the sub-assembly wanted and photographs of the plate or the front panel can be enough to start cross-checking before supply routes are reviewed. For a hydraulic hose on a crane, winch or hatch cover drive, the hose assembly builder writes the hose type, size, both end fittings and the length as one line. For the wire rope of a crane or winch, the wire rope designation reader explains the construction, core, grade, finish and lay from the reel tag. For a leaking cylinder on the same machinery, the hydraulic cylinder calculator checks the bore and rod against ISO 3320 and writes the seal kit line, and the lubricant code reader reads the oil or grease code from the drum. For a hydraulic pump or motor on a winch or crane, the hydraulic displacement calculator works out flow, speed and torque from the displacement on its plate. For a lift with a deck or provision crane, the weight shift list calculator gives the list from the weight, the outreach and the GM of the present loading condition. The tools for deck machinery and the hull are also gathered on one view of the measurement tools page.
Yes, and on deck machinery that is the normal case rather than the exception. A steering gear plated Rolls-Royce or Ulstein Tenfjord is the same Tenfjord machine under a later ownership name. A hatch cover plate may name a builder other than MacGregor outright, because these covers are supplied and serviced under several yard-fitted names. A brake asked for as Pintsch Bamag is usually plated Pintsch Bubenzer after the two brake houses merged. Send the plate as it reads and the name you use, and put both on the request.
From the brake. A KFB or SFB unit is read from its own type plate rather than from the winch or crane it is fitted to, and the execution weighs as much as the series: a seawater-resistant SFB execution changes which parts are supplied. Say whether the arrangement is disc or drum, and whether the release unit is wanted or only the linings.
Because the model name does not identify the unit. Mini transmitters are modular and come with linear levers or with joysticks and additional buttons and switches, so two units sold under one name can carry different controls and the function count is what identifies them. A G2 or G2B receiver adds its own variable, since it is supplied with proportional and digital outputs and with a CAN interface. An RC 400 replacement is paired to the receiver already fitted rather than ordered by model. A front-panel photograph settles all three.
Yes. Add vessel / IMO, port, ETA and which system is affected — steering gear, deck machinery brake, hatch cover or remote control. This helps prioritize the supply route.
Send the plate as it reads, the sub-assembly wanted, the item list, quantity and port/ETA. Photographs of the plate or the front panel, drawings, manual pages or Excel lists are welcome.
