Paxman History Pages - Valenta and VP1. Applications. Valenta and VP1. Applications. This page shows a selection of the applications of the Valenta range of engines and its successor, the VP1.
The Valenta was introduced to the market in 1. VP1. 85 in 1. 99.
Key markets for both engines have been naval and rail traction applications, continuing Paxman involvements with both which stretch back to the 1. From the late 1. 98. This factor and the capabilities of the VP1. Company to actively pursue additional applications, in particular main propulsion engines for the fast ferry and luxury yacht markets.
There has also been renewed focus on the industrial gen- set market. Although this market is highly competitive the Company has been successful in obtaining orders to supply prime movers for large specialist sets for some prestigious projects. Valenta (Y3. J or RP2. Applications. RAIL TRACTIONThe British High Speed Train (HST) More than 2.
Valenta engines have been supplied for the HST, now better known as the Inter. City 1. 25. The first two engines were delivered in 1. HST. Because 3. 0 years have elapsed since then, the magnitude of the technical achievements involved is often forgotten. The Valenta was not ready for the market until 1. HST project was a major step into uncharted territory. Yet, just a year after it was built, in June 1.
HST with its two Paxman engines established a world speed record for diesel rail traction at 1. In 1. 98. 7 it beat its own previous world record with a speed of 1. More about the HST's story appears on the Diesel Rail Traction page.

The Australian XPT (Express Passenger Train) In 1. State Rail Authority of New South Wales introduced its XPT which was based on the British HST. Originally fifteen XPT power cars were built and Paxman supplied twenty 1. Valentas for the project.
The trains were so successful that in 1. SRA decided to order four more power cars for which a further four Valentas were ordered. NAVALRoyal Navy Type 2.
From jet boats to cruisers, the Air-Dock boat lift can hoist them all.

In most applications, Air-Dock boat lifts can be installed without getting into the water. This is especially nice in the northern climates where boat lifts often need to be installed and removed each winter.
ASW Frigates Designed for Anti- Submarine Warfare, a key requirement for these Duke Class 1. A CODLAG (Combined Diesel- Electric And Gas) propulsion system employs diesel- electric drive when the ship is in 'slow speed silent mode' or when manoeuvring or cruising. For high speed operation the boost is provided by two Rolls Royce Spey SM1 gas turbines. Power for the diesel- electric drive and all other on- board electrical requirements is provided by four gen- set modules built by Paxman. Each module is mounted on a fabricated steel raft, allowing the engine and generator to be installed or removed as a single unit.
The prime mover for each set is a 1. Valenta producing 1. MW at 1,2. 00 rpm. Two of the four modules per ship are located below the waterline.
These are double mounted and fitted with acoustic enclosures to minimise noise. The first set of four engines for the Type 2. Spring 1. 98. 6. Sixteen Duke Class ships were built. Royal Navy 'Sandown Class' Single Role Minehunter The first of twelve boats in this class, HMS Sandown (M1. The twelfth, HMS Shoreham M1. November 2. 00. 1 and commissioned in summer 2.
Built by Vosper Thornycroft, each is powered by two low magnetic 6 cylinder in- line Valentas, each producing 1,5. These 5. 2. 5 metre vessels are one of the very few applications of the 6 cylinder in- line version of the Valenta.
The 6 cylinder Valenta was also supplied for similar Minehunters for the Royal Saudi Navy. Pictured here is the 6 cylinder Valenta used in the Sandown Class Minehunter. In the foreground, at the drive end of the engine, is the Vulcan coupling. The white paint is the preferred finish of the Royal Navy. It has the advantage of making any oil leaks immediately noticeable! United States' Coast Guard Service .
An important weapon in the US Government's war against drug smuggling, these 1. Bollinger Machine Shop and Shipyard Inc at Lockport, Louisiana, USA. Paxman initially received an order for forty eight engines for them in 1. The thirty seven class A and B . In 1. 99. 0 Paxman received an order for thirty two engines for the eight of these 5. US Navy. The boats were built by Bollinger Machine Shop and Shipyard Inc of Lockport, Louisiana.
The first 'boat set' of four engines was despatched from Colchester in March 1. USS Cyclone, the first of its Class, underwent sea trials in the summer of 1. With their four screws, each driven by a 1. Valenta RP2. 00- 1- CM producing 3,3. Cyclone Class boats have a design speed of over 3.
In 1. 99. 1 another five boats were ordered, resulting in an order for a further twenty engines. There are fourteen boats in the Class and at least 6. Valentas have been supplied for the PBC programme. The first thirteen were commissioned as follows: 'Cyclone' and 'Tempest' - Aug 1. Hurricane' - Oct 1. Monsoon' - Jan 1. Typhoon' - Feb 1.

NAVALRoyal Netherlands Navy LCF Air Defence and Command Frigates Paxman supplied the generator set modules for each of four Royal Netherlands Navy frigates built by the Royal Schelde shipyard at Vllissingen in the Netherlands. The 1. 44 metre ships are designed for a crew of 2. Pictured left is one of the modules nearing completion in Paxman's works at Colchester. There are four modules per ship, each powered by a 1.

They generate electrical power for all on board requirements including the weapons systems. The modules have double raft mountings for shock attenuation and are acoustically enclosed. RV Triton This demonstrator trimaran frigate is a two thirds scale prototype of a vessel which could eventually replace the Types 2. Frigates of the Royal Navy. Built by Vosper Thornycroft for the Ministry of Defence's Evaluation and Research Agency, the triple hull design reduces drag by 2. The power for its diesel- electric propulsion is provided by two 1.
