SOGREAH CONSULTANTS INVESTS OVER A MILLION EUROS IN ITS PORT REVEL CENTRE

On Thursday 30 April, Sogreah, a firm of consulting engineers working in the fields of water, energy and the environment, launched the "Otello", a 1:25 scale model of one of the largest French container carriers. This event was part of the celebrations to mark the extension of its Port Revel shiphandling training centre. Representing an investment of over one million euros, the new facilities consolidate the centre's worldwide leadership in training pilots in shiphandling operations. Ranked by the American journal Engineering News-Record in 2008 as one of the world's top 5 port and maritime consultants, Sogreah has been meeting the highly specialised training needs of the pilots and captains of very large ships for over 40 years. The idea that lay behind the creation of Port Revel on a shallow lake of the Chambaran hills in North Isθre, France, in the 1960s is still just as valid today, namely using the group's expertise in physical modelling and the simulation of maritime phenomena to recreate navigation conditions as faithfully as possible. This system, which is better than any numerical simulator, uses model ships (at scale 1:25) sailing on a specially developed lake (with waves, currents, wind and shoals) giving the on-board pilots "the same sensations as in the real world".

Launched in October 2007, the Port Revel development programme yet again aims to address the needs of maritime pilots. As maritime trade explodes and the size and tonnage of ships increase, pilots' experience and know-how are increasingly decisive in handling these gigantic vessels safely in port and coastal areas, where there are many kinds of hazard. By extending the lake to cover a total of 5 hectares, of which 70% is shallow water, doubling the number of quays and installing additional current-generating equipment, Port Revel can now offer an extremely varied range of situations and host 10-12 trainees each week as opposed to 8 previously. The construction of Otello, which is a faithful reproduction of a 334 m container carrier capable of transporting 8500 TEU, bears further witness to Sogreah's intention to keep abreast of current developments. With this new model, mariners can experience the sensations of working on one of the giants that now ply the world's oceans. Since the beginning of April, when the centre reopened, numerous French, Canadian, American, Belgian, Danish and Norwegian pilots have already been able to appreciate the new installations. Some 200 are expected in the months ahead to attend conventional courses or customised programmes drawn up by the centre's experienced and highly motivated instructors to suit particular requirements.

1. A major extension of the lake



The shallow parts of the lake (less than 27.5 m in real conditions) have been extended to cover 70% of the total area.

The areas subject to currents now cover half of the entire lake. With these modifications, Port Revel is clearly focussing on shiphandling in the vicinity of ports and coasts, where risks are greatest.

2. A new ship



A model of the CMA CGM Otello has been built to 1:25 scale, the same as that used for all of the 12 other models at Port Revel.

The scale model reproduces the smallest details of the real ship in terms of handling and behaviour at sea.

The main characteristics of the real 8500 TEU container carrier are:
• Overall length: 334 m
• Breadth: 42.8 m
• Draught: from 10 to 14.50 m:
• Windage: 10 000 m2

The first tests carried out with the scale model showed that Port Revel has complete mastery of modelling techniques as the real ship's captain said that the model perfectly imitated the typical behaviour of his own vessel. Further proof that Mother Nature (in the form of hydraulics) is at work on the model as on the real ship without it being necessary to write all the equations for the hydraulic phenomena involved. The realism of scale models is unequalled and for the moment has not been bettered by any other form of simulation. As maritime safety becomes an increasing concern, Port Revel is even more relevant than ever in training ships' captains and pilots to handle emergency situations.

The European and North American pilots who make up 80% of the Centre's trainees are well aware of this, and it is expected that other European captains and pilots will soon attend also … In order to answer these needs, Port Revel proposes several types of shiphandling training on manned models:

• Basic pilot & master courses
• Refresher course
• Escort tug course
• Emergency shiphandling course
• Offshore course
• Gas carrier/car carrier/container vessel course
• ULCC course
• Pods course

The Port Revel Centre was the first of its kind to be be created in the world, and it offers significant advantages:

• over 6000 experienced pilots and captains have been trained there since 1967 (mainly from the USA, Canada and Europe), and many of them are now coming for the second (and even third) time in their career,
• instructors are highly experienced and motivated maritime pilots,
• the fleet of 10 models at scale 1:25 reproduces 20 different vessels,
• 3 escort tugs are operated by a real tug master at the pilot's orders,
• Port Revel has inherited Sogreah's century of experience with scale models, numerical simulation, port planning, design & construction,
• the 5 ha lake is most versatile with very little interference from wind; it also features extensive shallow water areas, a long canal, the new Panama locks, an SBM and numerous quays; it is also equipped with wind, wave and current generators and a DGPS for accurate debriefing of the exercises performed on the lake.

A few technical details
The ships are precisely reproduced to a 1:25 scale and are equipped with indicators giving rudder angle, engine speed, ship speed and heading, wind speed and direction, etc. Most of the ships are equipped with bow and stern thrusters and with perfectly operational anchors. They behave like real ships.

Two of the three tugs are fitted with Voith Schneider propulsion and the other with a Z-peller system. The tugs are controlled by the pilot via a remote-control system.

35 years' experience has shown that trainees quickly learn how to control the models just as they do the real ships that they are used to manoeuvring.

A few words of background history …

After three years spent with Esso captains at the end of the 1960s, the Centre was taken over by Sogreah in 1970.

During the 1970s, most trainees were captains, while the first pilots came to discover the centre. During the 80s, the ratio of 9 captains to 1 pilot was reversed.

In the 90s, the first refresher courses were organised for pilots, who returned every 5 years. These courses are less directive and leave more room for customisation, which is a way of optimising port operations to increase port accessibility.

During the current decade, we have seen a change in our relations with mariners. We are now moving towards a closer partnership in which students use our installations at their convenience. Courses and equipment are specially designed in close collaboration with them, such as the courses on operations using escort tugs, with our friends from San Francisco.
