Sub-Dimension Engineering Co Ltd

Are British owned, submarine manufacturers. We are a specialist design & manufacturing facility catering specifically to the design of submarines of all types up to 160T in size.  This also includes remote operated submarines, (ROVs) & manned submarines.  We are one of only three submarine manufacturers in the Far Eastern region & the only submarine manufacturers located in Thailand. 

Sub-Dimension Engineering Co Ltd also specialize in remote intervention tooling for use with submarines of all types.  With our in house design & manufacturing capability we can offer the following goods & services:- 

ROV Manufacturing

Launch & Recovery Systems

ROV Components including DC Thrusters & AC Thrusters

Manned Submarines

Remote Intervention Tooling

Subsea Engineering Design

ROV Tooling Rental including Hydraulic Cutters & HID Lights Systems

Pipeline flange assembly tooling sales & tooling rental 

ROV

We offer  4 models of ROV:-

‘Odyssea’

‘Orion’

‘Pulsar’

‘AquaJack’

100HP Timber felling system complete with Launch & Recovery System 

Our ROV manufacturing philosophy is based on a modular approach. All of our ROV systems are designed to a high standard, with a very comprehensive specification using only the best ROV components.  Our systems are modular in construction with designs,  optimised for future upgrade capability.  All of our systems use Siemens PLC based control technology, for reliability, availability & longevity.  OEM ROV manufacturing, or OEM ROV component manufacturing, design variations & bespoke design & manufacturing services are also available. 

Submarines

We offer bespoke designs for new manned submarines for, tourism, research submarines & military applications, from 2 to 50 passengers capacity.  Manned submarines refits, upgrades  & retrofits are also possible.  We presently have one military application build underway.  We have retro-fitted several submarines’ DC Thrusters with our own in house design AC thruster systems with great success. 

Remote Intervention Tooling

An important aspect of ROV manufacturing, is remote intervention tooling.  We offer remote intervention tooling both for sale & also a tooling rental service on specific items such as hydraulic cutters, HID lights & also special ROV components such as compensators, cameras & pan & tilt units – details are available upon request.  Please inquire using our contacts page for tooling rental prices & availability.

Hydraulic cutters are available for wire, from 1” to 4” diameter. We also do a range of hydraulic cutters for cable (telecom's) & soft line from 1” to 3”.  Other tools include; Chop saws, hot stabs, jetting pumps, dredge pumps, borehole cameras.  Trencher , Plough & Diving bell HID lights systems & diver work site ‘flood’ HID lights systems.

We are the licensed agents & OEM manufacturers for the ‘GIT’ range of pipeline flange assembly tools.  These include a range of flange assembly tools for pipelines from from 4” to 40” diameter.  Flange assembly tools such as gasket insertion tools, flange catchers, flange ‘pull in’ accessories, podgers, hydraulic flange splitters & metrology jigs  are available for sale to order or flange tooling rentals may be possible on selected items.  Please contact us for further details. 

Bespoke designs are also possible for: ballasting skids, tooling skids, jetting skids, trenching skids & winch pull in skids. 

Submersible motors & pumps

We offer a wide range of electric submersible motors & matched hydraulic & water pumps:   We have our own models which are drop in replacements for most of the popular models in use today.  We can supply: ROV HPU submersible motors, trenching HPU submersible motors, trenching  jetting  pumps, plough HPU submersible motors, plough jetting pump sets, turbine & centrifugal water pumps, hydraulic pumps, Rexroth A7 & A10 series, Sauer 90 series & Kawasaki.   

We also offer an extensive range of ROV components for; ROVs, trenchers & ploughs:  DC thrusters, compensators, HID lights, halogen lights, control systems, valve packs, electrical junction boxes, pods, pan & tilts.  We also offer AC thrusters as direct replacements to existing DC thrusters from 1kW to 50kW in size –  all enquiries are welcomed. 

Soft Starts & Variable Speed Motor Control Systems

A large part of our business is the design, manufacture & installation of inverter based, variable speed motor drive systems ,used with commercial fishing pumps, DC thrusters replacement, subsea winch drives, subsea trenchers, jetting pumps,  surface umbilical winches.  Soft starts, HVTUs, isolation transformers, induction , capacitance & line filtration components are also available.
