March 4, 2004

Ecuador orders patrol vessels

FBM Babcock Marine and Spanish licensee Astilleros De Murueta have won a contract for construction of three 45 meter (150 foot) Vigilante design patrol vessels for the Coast Guard Command of the Armada de Ecuador (Ecuador Navy).

The Vigilante is a 45 m patrol vessel and is a registered design from the FBM Protector class, designed as a reliable, highly capable but cost-effective patrol vessel. Capable of over 25 knots, the Vigilantes will give Armada de Ecuador a new level of capability for the Armada de Ecuador. They and will be utilized for coastal patrol duties, coupled with an offshore role extending 600 nautical miles into the Pacific Ocean to the Galapagos Islands.

Astilleros De Murueta in Gernika, Spain, has established an excellent reputation for delivering high quality vessels of up to 150 m in length from first class construction facilities. Established in 1943, the yard builds a wide variety of ship types, including tugs, fishing vessels, general cargo carriers, ro-ro's, reefers and container carriers.

Augustín Ortiz de Eribe, Managing Director of Astilleros De Murueta says "This is an important contract for Astilleros De Murueta and is an excellent example of the wide capability and reputation for quality that our yard has established. Our licensing partnership with FBM Babcock Marine has allowed us to enter an important new market in the construction of patrol vessels, and the excellent design of this vessel was a major part in winning this contract. The Vigilante is a class leading vessel and offers a reliable, highly capable vessel coupled with being a cost-effective solution to the customer's requirements."

John Warbey, Managing Director of FBM Babcock Marine says "The selection of the Vigilante for this prestigious contract recognises the excellent design capability of FBM Babcock Marine, coupled with the renowned build capability of Astilleros De Murueta. This 45 m Protector Class vessel provides a highly capable and economical solution for a challenging requirement. With the recent deliveries of six 27 m Protector Class training vessels to the U.K., the continuing build of 33 m Protector Class patrol vessels in Chile, of which 14 have so far been delivered, and the continuing deliveries of 15.5 m aluminum landing craft to the U.K. Ministry of Defense, this maintains FBM Babcock Marine's long heritage in the international patrol boat market and highlights our strong position as a leading designer and builder of commercial, military and law enforcement vessels."

The Vigilante features a steel hull with aluminum deckhouse.

The hull is an all welded steel monohull form, consisting of a chine hull type with deep v-sections forward and large skegs. The design features trawler type bows with generous freeboard and a soft nose stem and large flare. The generous freeboard delivers a boat with excellent seakeeping and is very dry, a feature further enhanced by the camber incorporated aft plus a radiused flared transom to cope with large following seas. The good seakeeping capability of the design is confirmed by their smaller sister Protector 33 patrol vessels which have been in successful operation in the hostile waters around Cape Horn as well as in The Gulf. The Vigilante is a further development of the Protector Class, incorporating a wider hard chine hull variation.

The deckhouse provides an extremely spacious wheelhouse with all round visibility and is fitted with a navigation space, communications room and ship's office, with the control station arranged for three man operation.

The wheelhouse features a walk around bridge wing and a flying bridge/observation deck that incorporates wind protection. The deckhouse is located towards the center of the vessel to minimize vertical accelerations and is designed to allow the vessel to roll up to 15 degrees alongside a larger vessel without the potential for damage to the superstructure.

Other onboard spaces include a laboratory, two berth sick bay, wardroom, spacious cabins, separate officers and crew mess, a well-appointed galley and adjacent storage areas for dry provisions, cold room and deep freeze. 

The vessel is designed for a complement of 27 and is equipped with a single berth cabin for the captain, two 2-berth officers' cabins, and four crew cabins (three 6-berth and one 4-berth), coupled with separate head and shower facilities. Three additional berths can be added in one of the crew cabins to increase the total compliment to 30 if required. The accommodations are designed for maximum habitability and comfort, with careful choice of layout to take account of vessel movement and the minimization of noise and vibration. Onboard air conditioning has been designed for the local climatic conditions and will provide a comfortable working environment when operating in tropical conditions of up to 40°C and 90% humidity.

The flexible propulsion package consists of twin MTU 16V 4000 M90 main engines driving fixed pitch propellers, coupled with a cruise/loiter capability using a smaller single MTU 12V 4000 M90 central engine and a fixed pitch propeller. This arrangement allows the vessel to achieve a maximum speed of over 25 knots, whilst also being designed to maintain slow speeds over long periods of time. The triple screw propulsion system, coupled with two rudders, combines mechanical reliability and simple, efficient operation with ease of maintenance. The engine space facilities include a spacious control room, engineers' store and work area. 

Operational capability of the Vigilante includes extended patrolling, while an emergency towing bit that gives the vessel the ability to tow a craft up to a similar size.

The central cruise/loiter engine allows the vessel to operate at a cruise speed of 12 knots and have a range of over 3,000 nautical miles, whilst provisions space and water, including a desalination plant to supplement potable water supplies, allows the vessel to spend at least 15 days at sea without replenishment when carrying a compliment of 30.

A 5.2 m fast daughter craft for rapid boarding duties is stowed on the aft work deck and launched using a hydraulic crane, which is also used for handling other embarked equipment.

The Vigilante is also designed with the capability of fitting additional fire pollution fighting equipment including oil dispersants and a boom delivery system.
