Israeli Sub Dakar.

Remember in our last newsletter the story about the tragic loss of the Israeli submarine Dakar on her maiden voyage in 1968, and the discovery by Nauticos Corp. 30 years later. The Dakar was a WWII T-class boat, built by the British and sold to the Israelis after modifications, upgrades, and sea trials. In 1968, the Dakar was en route to Haifa via Gibraltar on her maiden voyage for delivery to the operational fleet. During this transit, communications inexplicably ceased and the submarine disappeared. Under contract for the Israeli Navy, Nauticos -- along with subcontractors Williamson & Associates Inc. (Seattle, Washington) and Phoenix International Inc. (Landover. Maryland) -- set out to find the Dakar in May 1999. The submarine was found badly damaged and resting at depth of 10,000 feet in the Mediterranean.
Well as an addition to this story we received the following letter from Stephen Donaghey.

Dear Alan
Thanks for your info and news letter.
I noticed a feature on the Totem submarine, and just thought I'd let you know my father served on HMS Totem. He told me that there was a totem pole mascot, which they were never allowed to sail without, apparently bad luck. When this sub was sold to the Israeli's we kept the totem pole, and the submarine sunk! ! Submariners are superstitious.
Just thought I would let you know.
Regards Stephen

Taurus Submarine.

Our Taurus submarine (normally six man, depth 1000ft) has recently carried out diving operations at the South African Navy base in Simonstown. In addition to the commercial, salvage, and scientific research operations that this submersible undertakes, Taurus is also designed to operate as a submarine rescue vessel (DSRV). In the rescue mode DSRV Taurus can shuttle twenty passengers at a time from a stranded military submarine. Currently a number of NATO navies as well as the South African navy are discussing this capability.

Hardsuit Diving Systems to Russia.

BOT has delivered four crane-based LARS to Oceanworks International Inc. (Houston, Texas) to be used with its Hardsuit atmospheric diving systems. These systems were supplied to the Russian Navy as part of a major investment in submarine escape and rescue equipment, made in the wake of Russia's Kursk submarine disaster. The four LARS are self-contained, air-transportable modular systems mounted on an ISO container base, allowing for easy shipment and installation on vessels of opportunity.

Ohio Class Submarines.

Electric Boat Corp., Groton, Connecticut, was awarded a $38.3 million contract modification to exercise an option for the procurement and manufacturing of long-lead-time material for the conversion of Ohio-class SSBN submarines to Ohio-class SSGN submarines. The Naval Sea Systems Command, Washington, D.C., is the contracting activity. Raytheon Co., Marlborough, Massachusetts, was awarded a $24.5 million contract for procurement of the Advanced Communications Mast (ACM). The ACM is a super high frequency antenna system to be operated on the SSN-23 submarine. It consists of electronic control equipment located in the radio room and antenna/transmitter equipment located in the sail. The ACM must interface with existing submarine systems as well as unique data source equipment installed only on the SSN-23 submarine.

Dual Deepworker submersibles for sale.

This exciting package of dual (2) Deepworker submersibles is now available for sale.

Each Deepworker is a one-man tetherless submersible capable of working in depths up to 2000ft.

Length: 8.25 ft.
Beam: 5.3 ft.
Height: 5.6 ft.
Weight in Air: 4700 Ibs.
Operating Depth: 2000 fsw.
Payload: 300 Ibs./variable
Life Support: 72 man hrs.
Max Speed: 2.5 knots
Crew: 1 pilot
Sonar: 675Khz Imagenix
Acoustic Modem: Datasonics ATM-870
Hydraulics: 2200psi Hydro-Lek
Manipulator: HLK-CRA6 6 function
Certification: Lloyd's Register of Shipping

Submersible pilots in the past have been constrained to only piloting the vehicle and monitoring his systems, which are critical tasks. Deepworker operators can be alleviated from a number of these tasks due to technology, modernization and the inherent ergonomic design of this particular vehicle. In this design the pilot is seated upright. The view port is a 25" hemispherical dome. The pilot can enter desired depth and heading data into the PLC and Instruct the PLC to maintain that course, depth and heading. The PLC will continue to perform that function until cancelled by the pilot. The versatility of the PLC along with the ancillary computer also allows for other capabilities such as acoustic electronic communication of critical operational information with the surface vessel. The submersible is outfitted with a six-function manipulator. Additional hydraulic tooling is easily integrated such as water jets, suctions, and guillotines. If necessary ,an additional manipulator can be installed for specific dexterity requirements.

Submarine/Auv Autopilot.

H Scientific Ltd. successfully commissioned its 3DMC autopilots on a manned submarine, on a fast RHIB (more than 30 knots), and on an airship. The firm's Dr. Henry Robinson said the firm's autopilot is "the world's first off-the-shelf autopilot for AUVs." The 3DMC, developed in collaboration with Chelsea Technologies Group (West Molesey, Surrey, U.K.), is designed to be applicable to a wide range of vehicles. Software configuration allows the autopilot to be connected to many different sensors and actuators. Recent trials illustrate the versatility of the autopilot, Robinson said, "working not only on such different vehicles in such different speed regimes, but also in different media, air, as well as surface and subsea. These successes demonstrated how effectively it can learn the characteristics of a new vehicle, typically in less than a minute." In each case the learning process worked first time, with no pre-tuning needed, he added. Visit the website at www.h-scientific.co.uk/

Marlin Building a new Submarine.

A small specialist company is currently building a diesel electric manned submarine. Classified as an American Bureau of Shipping +A1 submersible, the Marlin AP6 will be a six-passenger, 18 tonne tourist submarine capable of diving to 302 meters depths. Richard Dawson said the intention is to provide a specialized service to enable interested tourists, scientists, and environmentalists to observe a wider spectrum of marine life and seabed conditions. The passenger section of the pressure hull will consist of two intersecting transparent acrylic spheres, 1.85 meters inside diameter and 100 millimeters thick. The passengers and crew will be treated to a spectacular all round view previously enjoyed only by the most advanced research submersibles, he said. The vessel will be the first ever to employ this twin sphere geometry. Construction is currently well advanced, and delivery of the pressure hull components (the only items that are not made in-house) is expected early in 2003. The craft is due for completion in early summer 2003, and after the completion of the sea trials off Plymouth in Devon, will be available for charter.

Autosub for the Antartic.

Dr. David Vaughn of the British Antarctica Survey will be using Southampton Oceanography Centre's Autosub to investigate the cavity under Pine Island Glacier, one of the fastest Antarctic ice streams. Satellites show that the grounded portion of the glacier thinned by up to 1.6 meters per year from 1992 to 1999. A large iceberg, 42 by 17 kilometers, broke off the Pine Island Glacier in early November 2001. Ice shelves are the floating edges of the ice sheets that cover Greenland and Antarctica. These shelves are involved in the waxing and waning of the ice sheets as climate changes. They contain over 70% of the world's freshwater -- enough to increase sea level by 80 meters if they melted entirely. But what takes place in the vast water cavities beneath ice shelves -- which can be a thousand meters thick -- is largely unknown. The autonomous underwater vehicle Autosub's unique capabilities will allow Vaughn to make the first direct measurements of the newly exposed bed of a retreating ice stream. The AUV will be diving to depths below 1,000 meters to gain access to the glacier cavity. On previous research missions in the open ocean, Autosub has been programmed to surface if she gets into difficulties. The engineering team at SOC designed a completely novel navigation system to overcome the dangers of working in an enclosed space. This research project is the first in the Autosub Under Ice Program funded by the U.K. Natural Environment Research Council.www.soc.soton.ac.uk/

The titanium sphere has now been constructed and tested for an operational depth of 4000m (12,800ft). Internal and external design is currently being undertaken prior to final outfitting. The basic design of this submersible offers the maximum adaptability to optimise the configuration of the vehicle for the roles required by the client. As a very deep diving one atmosphere submersible, the main tasks envisaged will be seabed search and survey, scientific research, and military applications.

Viking Submarine Project Enters New Phase.

The Viking Project has now reached the tendering phase. The Swedish, Norwegian and Danish navies - have recently submitted specifications that will form the basis of this tender. The Viking Submarine Corporation is a joint venture between Kockums AB of Sweden, Kongsberg Defence & Aerospace of Norway and Odense Staalskibsvaerft A/S of Denmark. The company will now submit a tender for project planning, which will form the basis for decision regarding design and construction of ten submarines: four each for Denmark and Norway, and two for Sweden. The submarines will be designed to operate under widely differing conditions, in terms of range, operational duration and deep-diving capability. A document has been drafted outlining the joint specifications of participating countries, covering the special requirements of each country. This is made possible by adopting a joint basic design that is sufficiently flexible to allow for modifications and add-on capabilities as required. This basic design specifies a submarine that combines completely air-independent propulsion with a substantial punch and extreme efficiency. The Viking class submarines will offer significant advances in stealth capability and a dramatic improvement in the surveillance function, featuring advanced sonars. The Norwegian version, with a mission profile involving extended periods on the surface, covering considerable distances, will be fitted with a diesel as well as AIP propulsion system.

SUBSEA, SUBMERSIBLE, ROV ELECTRIC MOTORS.

Silvercrest/SME can design and build Motor-pump sets, ROV HPU, SUBSEA, SUBMERSIBLE, ROV motors to suit any requirement due our totally flexible design capabilities:

      Flexible External Dimensions to suit all applications.

       Dimensions to allow drop in replacement for existing units.

       Anodised aluminium, or, 316 stainless steel.

       Power drive to load using an output shaft with a standard coupling, or, close coupled, etc.

       Single drive shaft, or, a drive shaft at both ends, (double shaft extension).

SME can design and build a motor with a completely new lamination to meet special design requirements, if necessary.

SME design their motors so they do not run hot. Typical motors can run on deck for at least 10 minutes on full load, with no cooling, without overheating. The motors are designed to be compact in size and suitable for heavy duty applications, like trenching.

If weight is important SME can design the motor for minimum weight by utilising an aluminium construction and a hollow motor shaft, etc., while still ensuring the motor is generously rated for full load operation. If the motor is going to drive a hydraulic pump we recommend a close coupled arrangement to save the weight of the coupling and the coupling housing.

SME can design and build motors for all voltages from 24 Volts to 4160 Volts with 50Hz or 60Hz frequencies, or for VVVF requirements. High Voltage motors can have random stator windings, or formed coils, depending on space and weight constraints. The winding wire for the High Voltage motors is double insulated and passes a twisted wire test at 16,000 volts and is rated up to 155 Deg.C. All windings are designed to keep 'turn to turn' voltage to a minimum. All winding materials and cables, etc. are specially selected to be suitable for use in hydraulic oil.

In general the SME SUBSEA motors have low loss lamination steel (3 Watts/kg), which allows for higher flux densities, and less heat, with less material and weight.

All motors are oil filled and we recommend hydraulic oils for good lubrication characteristics in preference to electrical oil which has better di-electric capabilities, but worse lubrication capabilities.

If motors are going to drive a water pump SME can design the motor to take the thrust load from the pump, and keep the sea water out of the motor with a single or double mechanical seal arrangement.

Thruster motors can be designed and built for voltage/speed control, which is a relatively simple speed control system, and they can also be built with a thrust bearing incorporated to take the thrust load from the impeller.

To ensure the integrity of the motor housing SME does not use castings. All components are machined from solid or from extrusions. The external aluminium components are typically 6061 T6 marine grade aluminium and hard anodised to a military specification.

All ball bearings are from well known brands such as SKF, FAG, or NSK. Oil seals are high temperature and typically made from Viton. Mechanical seals are typically Burgmann.

All hardware used on SME SUBSEA motors is 316SS.

All fixing holes are blind except the "oil in" and "oil out" fittings and the stator pack fixing bolt, if applicable.

The preferred power cable entry system for SME motors is to use an "oily tube" connected to an adaptor which is part of an oil tight rubber gland which is fixed to the stator frame. SME do not recommend bringing the power cables through the endshields of the motor because this creates additional complications when the motors are stripped down during service, because the endshields cannot be readily removed from the stator. Subsea connectors can be offered as an alternative to the Oily Tube if requested.

SME strongly recommend that the motors are supplied with PT100s fitted in the windings and also in the bearings and that the internal motor temperatures are monitored and set up to alarm if the temperatures rise above the "norm". SME can also offer additional protection with a water detector, etc. The auxiliary connections for PT100s, etc. can be made through standard high pressure, water tight, plug and sockets as supplied by "Subconn", "Impulse", and "Burton". These are also fitted to a connection block on the stator, not on the endshield.

All finished motors are pressure tested to ensure they are "oil tight" and suitable for compensated operation down to 4000 metres.

All motors are rated for continuous operation and all prototype motors are full load performance tested at rated voltage and rated frequency to confirm their performance characteristics. All motors can be issued with a "Type Test Certificate" or even full load tested at additional cost, if required.

SME can also offer to arrange for hydraulic pumps to be set up and tested on the motors at rated voltage and frequency.

SME can offer to supply Hydraulic Power Units, ROV HPU, complete with the addition of a customer specified Hydraulic Pump. Also motor-pump sets for both hydraulic and water jetting applications.

SME is a fully quality assured company to ISO 9001.2000 for "Design, development, manufacture, and testing of submersible electric motors and electric motors for remotely operated vehicles".

SME Subsea motors can be designed and built for all subsea applications, such as ROVs, Trenchers, Ploughs, Submarines, Dredges, etc.

All makes of subsea motor can be serviced, repaired and tested by SME. In some cases the original motors can be significantly upgraded. If you are having problems with your existing subsea motors please contact SME - we are keen to help and we are very price competitive.

At SME we are continually working on improving the performance of our products and for this reason we reserve the right to make changes without notice to any of the data in this brochure.
