Crewing: The crew of 44 onboard consists of a 5 officers and 39 crew members. Officers include a Commanding Officer, an Executive Officer, a Chief Engineer, a Navigator, and an Operation Officer Crew positions include a Chief of the boat, a Medical Assistant, 6 Communication staff, 3 logistics personnel, a Chief Boatswain, 2 ship’s administrative staff, 2 cooks, 5 deck personnel, 6 electricians, 6 hull maintainers and 6 mechanics / propulsion technicians..

Noise Control: ALLIANCE is one of the most quiet research ship in the world. Special acoustic quietness methodology were incorporated in the design from the onset. The ship’s prime movers are all encased in acoustic hoods and resiliently double mounted to reduce the structural transmission of vibration to the hull and subsequent transmission to the water. Air for combustion and cooling purposes required the installation of air inlet silencers in the supply ducting to prevent breakout of diesel noise into the machinery space. Likewise, exhaust silencers have been fitted in the exhaust system. Piping systems have been fitted with flexible connections and piping design eliminate flow noise through low radius curvatures. Damping tiles have been installed in the sea chests to make them act very much like an absorptive type of muffler and on the underwater hull to eliminate as much as possible sources of noise. Pipes and ducts also vibrate and for those systems that operate in the lower noise states, they have been isolated from the vessel's structure by the use of resilient hangers. Container Capability: In ALLIANCE, there is the capability to embark up to five (5) standard ISO 20 ft and up to three (3) standard ISO 10 ft containers as follows:

2 20 ft on Quarterdeck Port and Starboard (power sockets available)

3 20 ft on Boat Deck Port Midships aft end (power sockets available)

1 10 ft on Forward Working Deck- forward of crane

(power sockets available)

1 10 ft on the Forward Working Deck – Midship

(power sockets available)

1 10 ft on Quarterdeck – Midship aft of main tow winch

(no power sockets available)

Communication and Navigation: Onboard ALLIANCE, there are two (2) independent systems for ship communications and for scientific trials (with some overlap). The ship system, which uses radios complying with SOLAS and GMDSS rules, includes VSAT interface and Inmarsat systems (E-mail, fax and phone) under the control of the Communications Officer. A military radio suite has been fitted to satisfy ITN communication requirement. The scientific network available onboard ALLIANCE is based on VSAT connectivity. The network link all scientific station in the main laboratory and can be configured in various ways to satisfy specific trial/experimentation requirement. A state-of-the-art Kongsberg Maritime K-Bridge INBS and MDM 400 Marine Data Management system are installed in ALLIANCE. This allows precision positioning to 4-5m and when the SEAPATH Real Time Kinematic (RTK) system is used, high precision positioning to 0.5m is achieved. Differential GPS corrections are received via satellite and this provides precise navigation throughout the Mediterranean and North Atlantic. Precise track control and auto pilot navigation is facilitated by direct computer steering between prescribed way points. As part of the INBS, the vessel can operate in a Dynamic Positioning Mode. Although capable to operate in DP mode (basic DP operations with position keeping accuracy of 1-1.5m up to sea state 3 and wind speed of 15 kn), the ship is not officially classed as a DP vessel. Depending on sea state and wind direction, the vessel can operate on DP in higher sea and wind conditions with position accuracy of up to 5m.

Accommodation: The accommodations in ALLIANCE for scientific personnel consists of one single suite, sixteen (16) single cabins and four (4) double cabins for the scientific complement. For the crew, the accommodation incudes five (5) single suites, one (1) single cabin, and nineteen (19) double cabins. Most of the scientific staff accommodation is located on the tween deck. The scientist-in-charge single suite is located on the officer's deck, while 5 single cabins for scientist can be found on the crew deck (starboard side). The lifesaving capacity and therefore maximum complement of the vessel is 69 persons.

ALLIANCE is fitted with a large U frame at the stern and is hinged so that it operates over the transom on the centre line. The underside of the eyebolts under the U-frame is 5.2 m above the working deck when turned inboard; when vertical there is 5.95 m clearance; useable width between the uprights is 5.27 m. The upper horizontal bar is extended outboard each side to cover the full stern width. The loading capacity is 10 t with snap load not exceeding 50 t. The SWL of the eyebolts in central section is 10 t. The A frame, located forward, is similar to the U frame except that it is 3 m wide at its upper horizontal bar which is extended at the forward end to provide support for a large sheave of 1.75 m diameter. The sheave is attached to a trolley traveler on the underside of the extended upper horizontal bar. The frame is hinged to operate over the port side of the vessel. The characteristics of the A-Frame are shown below. The main tow winch onboard is a large capacity double drum winch, located mid-ship on the quarterdeck. The characteristics are found below.

The ship can also be fitted with a towed body winch on the starboard quarter deck. The Data winch, located on the Focsle - Starboard side aft, is a split winch with drum diameters of 1600 mm and of 1000 mm works in conjunction with the A part of the A - frame. The large drum winch, located on the Focsle - starboard side forward works in conjunction with the extended part of the A- frame. An Oceanographic winch, located in a room of the same name (starboard side of the Weather Deck at frame 96) has the following characteristics. The winch design incorporates a telescopic arm capable of extending through a hydraulically rammed door located in the starboard side of the vessel. The telescopic arm is hydraulically operated and when fully extended will reach 5 m beyond the side of the vessel for deployment of oceanographic sensors. The Chum winch is exclusively used for deploying a towed acoustic sound source operated by CMRE specialist staff. The speed is continuously variable from 0 to 60 m/min. The spooling gear is automatically operated and the winch structure can support an unexpected over-tension up to 16000 kg. ALLIANCE is fitted with two workboats (Rigid Inflatable type RIB) which serves as fast rescue boat and workboat for scientific purposes.

The main generators are AEG Type DKBL 634/06, 1799 kW, 60 Hz, self-excited, brushless, AC synchronous machines operating at 1200 r/min. They have IP 44 enclosures with a top mounted, double tube, sea water cooler and are constructed for continuous full power operation at 0.7 power factor. Each generator is driven by a Grandi Motori Trieste diesel engine. The AEG Type DKBH 4504/04 auxiliary propulsion generator is dual-rated at 1300KVa/680KVa, 0.75 pf for 440 V and 680 kVA, 0.6 pf for 260 V. It is a self-excited, self-ventilated, brushless, a.c. synchronous machine operating at 1800 r/min. It has an IP 23 enclosure and is driven in tandem with the silent ship services generator by a Kongsberg gas turbine. The propulsion motors are AEG Type GC312/128/8 KZ 90/24, low ambient noise, low vibration machines developing 1470 kW and requiring 2150 A at 750 V DC at full power. They have separate field windings fitted with discharge protective devices and are designed for fully reversable operation from static regulators. The motors have IP 44 enclosures and top mounted, double tube, air/seawater coolers. Each motor has two flanged fitted friction bearings and is resiliently mounted and coupled to the propeller shaft. The motors are designed for full 100% torque operation from 0-130 r/min and for 100% power operation using field weakening from 130-160 r/min. The electric propulsion system powers the bow thruster and is completely independent of the service and other electrical systems. When the bow thruster is in operation, power sharing is automatically programmed

between the main propulsion motors and the bow thruster. The bow thruster cannot be operated in conjunction with the Gas Turbine. The motors can be operated and controlled from the Machinery Control Room or Bridge. The electrical systems and equipment have been designed and installed in accordance with RINa, ABS and IEC 95 requirements. Grounding in accordance with MIL STD 1310 D and VDE 0875-0877 has been used to reduce the probability of electromagnetic interference. All equipment has been selected and installed for minimum electromagnetic radiation and radiated ambient noise levels.

The electrical system has been designed to provide power only to those items designated for use in the particular noise operating states. Highly stable electrical power for the scientific laboratories and services is provided by three AEG solid state 62.5 kVA inverter units, supplied from the 1050 A h battery bank.
