1 INTRODUCTION The Light Weight Taut Wire Mk 15B is a position reference system designed for use in a deck-mounted port or starboard position on surface vessels. The purpose of the Light Weight Taut Wire system is to provide accurate data of the vessel's movements, relative to a known point, in the fore/aft (along-ship) and port/starboard (athwart-ships) directions.
The equipment includes high voltages, which means that the possibility for getting an electrical shock is present. Before commencing any installation work, read the guidelines for First Aid treatment of personnel with electrical shock. Cables between Taut Wire Unit and Electrical Cabinet must not exceed 50 m. Signal cables must not be located with cables whose charging magnetic field may induce voltage.
Caution The Light Weight Taut Wire Mk 15B is delivered with sufficient hydraulic fluid inside. No refilling or topping of hydraulic fluid should be done by yard/customer during installation or before setting to work.
Note Unless stated otherwise, all mounting equipment referred to within this document is to be supplied by yard/customer. The guidelines for installation presented here must be regarded as a base for detailed plans prepared by the installation shipyard. These plans must include drawings, instructions and procedures specific to the ship in which the equipment is to be installed. These drawings must be approved by the local maritime classification society. Unless stated otherwise, all installation work described in this document is to be performed by yard/customer personnel. It is the responsibility of the yard/customer to assure that their installation personnel are sufficiently qualified, and that proper caution is taken to avoid injuries or damage to life, health, environment, equipment and property. Kongsberg Maritime AS accepts no responsibility for any damage or injury to the system, ship or personnel caused by drawings, instructions or procedures not prepared by Kongsberg Maritime.

3 INSTALLATION This chapter presents the procedures for installation of the Light Weight Taut Wire Mk 15B supplied by Bandak AS.
3.1 General information The overall dimensions of the Light Weight Taut Wire Unit are shown in Figure 1 to Figure 3.
3.2 Location of the units
3.2.1 Light Weight Taut Wire Unit The Light Weight Taut Wire Unit must be installed at the side of the vessel and as close to the water surface as possible. The reason for this is to obtain the maximum possible inboard angle, see Figure 4 for the operational area of the wire. This will also result in the minimum pendulum movement of the depressor weight when clearing the water surface. Excessive pendulum movement stresses the wire and is often the main reason for wire breakage. The unit should not be installed above the thrusters because the water movement from the thrusters (when they are running) may affect the wire and cause the sensor head to send false information to the data processing system. It is important to ensure that the deck supports are sufficiently strong to avoid unwanted mechanical deflection in the deck and foundations, which can affect the measured results. The location on the deck where the Light Weight Taut Wire Unit is to be positioned must have a maximum elasticity of 1.5 mm.
3.2.2 Electrical Cabinet The Electrical Cabinet should be located in an indoor environment, satisfying Environmental Specifications in section 2.
Cables between Taut Wire Cabinet and the Electrical Cabinet must not exceed 50 m. Signal cables must not be located with cables whose charging magnetic field may induce voltage in the signal cables.
Note Ensure that the electrical cabinet has sufficient space both for mounting and for service area, see Figure 5.

178539/D 11
WARNING
3.2.3 Remote Control Unit (optional) The Remote Control Unit should be located in an indoor environment, satisfying the Environmental Specifications given in section 2. For space required, see drawing S-03205 (drop-in unit).
3.3 Logistics Safety: General safety precautions should
be followed when working on/with Light Weight Taut Wire Mk 15B
Personnel qualifications: Two trained mechanical workers, and one trained electrical workers.
Min. no. of personnel: Three. Ship location: No recommendations. Special tools required: None.
3.4 Handling
Never, ever pass or stay, complete or partly, under any lifted object.
3.4.1 Light Weight Taut Wire The Light Weight Taut Wire Unit has three points for the attachment of lifting slings. When the unit is to be lifted, the boom must be lowered down into the operational position and all three slings attachment points must be used. Use three nylon slings. Two are passed through openings in the main structure whilst the third is passed around the foremost upper part of the weight-basket (see Figure 10). All three slings shall have a length from lifting point to the hook of 2 m.
3.4.2 Electrical Cabinet The Electrical Cabinet includes delicate electronic components and should be handled accordingly. Appropriate lifting equipment should be used and care must be taken when handling the Electrical Cabinet. Use the eyebolts (DIN 580) on top of the cabinet for attaching lifting slings (see Figure 6). Minimum angle of the lifting sling at the base is 60°.

3.4.3 Remote Control Panel (optional) The Remote Control Unit includes delicate electronic components and should be handled accordingly. The Remote Control Unit can be lifted by hand.
3.5 Mechanical installation
3.5.1 Light Weight Taut Wire Unit A base frame (see Figure 8) serves as the foundation for the Light Weight Taut Wire Unit. It is constructed of HEB-120 section girders and steel plates that are welded together. It is recommended that the base frame is welded to the deck. In the top of the base frame there are twelve (12) 18.5 mm holes for securing the Light Weight Taut Wire Unit to the base frame with M16 type A4 80 bolts, torque to 214.5 Nm. For the calculated maximum load acting on these 12 attachment bolts, see Figure 9.
Note The frame shall be mounted in such a way that the Light Weight Taut Wire Unit be standing horizontally levelled and 90° on the along-ship axis.
3.5.2 Electrical Cabinet
Note Prior to installation the Electrical Cabinet, ensure that necessary service area is available. For details on service area and general space requirements, see Figure 5. The Electrical Cabinet is attached to a yard/customer supplied base frame that is attached to the floor through welding The Electrical Cabinet is attached to the base frame by use of four M8 bolts (bolts to be supplied by yard/customer). The base frame has to fit the footprint of the Electrical Cabinet, see Figure 8.
3.5.3 Remote Control Unit (optional) The optional Remote Control Unit is supplied as a Drop-in type see drawing 3-7728, where the Remote Control Panel is connected to the electrical cabinet (cable #2) TB 31.
3.5.3.1 Drop-in Remote Control Unit
The Drop-in Remote Control Panel protrudes 80 mm below the cabinet front. Before commencing any mechanical installation, ensure that sufficient space is available inside the cabinet.

The cut out and overall dimensions of the Drop-in Remote Control Unit are shown in drawing S-03205. The Drop-in Remote Control Panel is mounted to the panel by four (4) bolts with nuts on the opposite side.
3.5.4 Pressurised air Pressurised air, usually from the vessel's working air supply, is used to set and regulate wire tension. The pressure connection point is located just underneath the Servo Motor, see Figure 11. The connection for the air supply is GE12LR 3/8".
