spaces, equipment and systems that correspond to a modern ship, in accordance with the with the fol- lowing design criteria: Hospital area located on a single deck, situated as low as possible for mini- mum accelerations in this area. Situated on the same level as the helideck and the rescue equip- ment for direct access from rescue operations and smooth passage of beds and cots to treatment area;

An accommodation deck is arranged between the engine room and the hospital zone to reduce noise. In addition, to reduce noise from the air conditioning system, its machinery is located in the engine room and the air conditioning in the hos- pital zone is separate from the rest of the ship. Air is not re-circulated. This system is described later on in this report; Natural lighting and ventilation are employed to the maximum. Corridors are designed to accommodate a flow of hospital beds with an accompanying person on the side. The doors of the patients' cabins are designed to accom- modate hospital beds. The patients' cabins have access to beds on both sides.

Rescue Equipment

Esperanza del Mar is equipped with efficient means for rescuing victims from accidents at sea, towing operations and assistance in different types of emergencies such as fires, breakdowns, pollution or natural disasters. That equipment includes

FRDC (Fast Rescue Daughter Craft) or "ambu- lance boat", type MP-100, manufactured by Mar- itime Partner and supplied by Pasch, of a 9.95 m length and 3.50 m beam, with capacity for 3 crew and 17 victims. Her engines (2 x 170 bhp) enable her to reach 32 knots. High-tech navigation and communications equipment are installed on her bridge. Three pneumatic rescue craft, each fitted with two outboard motors. • G67 davit for FRDC craft, of a 10 m reach and 6.7 t SWL, and two G15, 1.7 SWL davits for res- cue craft, all produced by Hydramarine and sup- plied by Pasch. • Tow hooks manufactured by Industrias Ferri • Two Pesbo rescue boats • Five D8B life rafts for 5x12 persons, with a launching platform, supplied by Llalco • Service boat with outboard motor

Also arranged on board is a Skum monitor to provide firefighting service to other ships

Propulsion and Maneuvering

Izar Manises participated actively in the con- struction of the hospital ship Esperanza del Mar.

The company also supplied a deck crane, and the complete propulsion pack. The ship is arranged with two separate shaftlines for total engine redun- dancy, to ensure rescue operations at all times.

Each propulsion line consists of a Mak Model 9M25 four-stroke propulsion engine with a power output of 2,700 kW at 750 rpm in compliance with

IMO NOx emission requirements. Each engine is coupled through a Vulkan resilient coupling to a

Reintjes WAF 4545 reduction gear of a reduction ratio of 3.42. Shafting 18.5 m in length and four fixed pitchpropellers by Balino of a nominal speed of 219 rpm. The system is fitted with braking ele- ments and the shafting has a clutch that confers the system broad operating flexibility. The electric power plant installed aboard the Esperanza del

Mar, supplied by Pasch, is composed of three gensets and one emergency set, all designed and manufactured by Demp. Three MAN D 2842

LE301, 12 cylinder in V auxiliary engines and one 500 kWe Stamford electric power alternator. These sets are cooled by means of a water/water heat exchanger with a centralized on-board water cir- cuit. An emergency genset with a MAN D 2842

LE201, 12 cylinders in V and a 500 kWe Stamford electric power alternator, cooled by means of an air/water radiator. Special care has been given to control noise emissions and vibrations, given the mission of this ship.

The weight/power/volume ratio of these gensets is excellent. The main and emergency switch- boards, as well as the control stations of engines 1 and 2 and the control console installed in the engine control room were built and supplied by

Isotron. Hispano Radio Marftima supplied the elec- tronic navigation, external communications and telemedicine.
