General supply conditions

The following supply conditions are applicable to this Simrad ES60 Fish ﬁnding echo sounder delivery.

Equipment responsibility

The shipyard performing the installation and/or equipment dealer becomes fully responsible for the equipment upon receipt unless otherwise stated in the contract. T he duration of responsibility includes:

• The period of time the equipment is stored locally before installation.

• During the entire installation process.

• While commissioning the equipment.

• The period of time between commissioning and the ﬁnal acceptance of the equipment by the end user ( normally the owner of the vessel which the equipment has been installed).

Unless other arrangements have been made in the contract, the ES60 Fish ﬁnding echo sounder system guarantee period (as speciﬁed in the contract) begins when the acceptance documents have been signed

Receipt, unpacking and storage

Upon accepting shipment of the equipment, the shipyard and/or the dealer should ensure that the delivery is complete and inspect each shipping container for evidence of physical damage. If this inspection reveals any indication of crushing, dropping, immersion in water or any other form of damage, the recipient should request that a representative from the company used to transport the equipment be present during unpacking.

All equipment should be inspected for physical damage, i.e. broken controls and indicators, dents, scratches etc. during unpacking. If any damage to t he equipment is discovered, the recipient should notify both the transportation company andSimrad so that Simrad can arrange for replacement or repair of the damaged equipment.

Once unpacked, the equipment must be stored in a controlled environment with an atmosphere free of corrosive agents, excessive humidity or temperature extremes. The equipment must be covered to protect it from dust and other forms of contamination when stored.

For more information, refer to Equipment handling on page 15

304699/A

General installation requirements

The following installation requirements are applicable to this Simrad ES60 Fish ﬁnding echo s ounder delivery.

Approval by classiﬁcation society

The ES60 Fish ﬁnding echo sounder transducer installation must be approved by Det Norske Veritas (DNV) or another classiﬁcation society. The shipowner and shipyard performing the installation are responsible for obtaining installation approval.

Supply power

The supply voltage to the equipment is to be kept within ±10% of the installation’s nominal voltage. Maximum transient voltage variations on the main switchboard’s bus-bars are not to exceed

-15% to +20% of the nominal voltage (except under fault

conditions).

Introduction

Simrad recommends that the ES60 Fish ﬁnding echo sounder is powered using an Uninterruptable Power Supply (UPS). The UPS should have the capacity to independently maintain power to the system for a minimum of 10 minutes. This ensures that the system can be switched off in a controlled manner in the event of a power failure.

Compass deviation

Once the installation is complete, the vessel m ust be swung with the system in both the operative and inoperative modes. The shipowner and captain are responsible for updating the deviation table accordingly with regard to the vessel’s national registry and corresponding maritime authority.

Noise sources

The vessel’s hull, rudder(s) and propeller(s) should be thoroughly inspected in dry dock prior to installation. Roughness below the water-line deformities in the shell plating and protruding obstacles can create underwater noise. These sources of turbulence must be smoothed or removed as best as possible. It is especially important that the propeller(s) is not pitted or damaged.

Dry d ocking

Make sure that ample clearance under the sonar trunk and/or protection blister is provided when dry docking the vessel. Avoid locating supporting blocks or structures in the vicinity of this equipment.

304699/A 13

Simrad ES60

Note

The location of the transducer and/or protection blister must be noted on the vessel’s docking plan for future reference.

Wiring

All cables running between system cabinets located in different rooms and/or on different decks must be supported and protected along their entire lengths using conduits and/or cable trays. Note that the cables must not be installed in the vicinity of high-power supplies and cables, antenna cables or other possible sources of interference.

Whenever possible, transducer cables must be run in steel conduits.

For more detailed information about cables and wiring, refer to

Basic cable requirements on page 80

304699/A

Equipment handling

This section provides the basic rules for transportation, storage and handling of units. In this context, a unit may be any large or small part of the system. It can be supplied as part of the initial delivery, or a s a spare part.

Transportation

Unless otherwise stated in the accompanying documentation, electronic, electro-mechanical and mechanical units supplied by Simrad can be transported using all m ethods approved for delicate equipment; (by road, rail, air or sea). The units are to be transported in accordance with general or speciﬁc instructions for the appropriate unit(s), using pallets, transport cases, or carton boxes as appropriate.

Note

Introduction

Special local restrictions concerning air transportation may be applied to units containing certain types of batteries. These units must be checked properly, and the regulations must be investigated by the packer/shipper before the unit is dispatched.

All local transportation must be carried out according to the same speciﬁcations as for the initial delivery. In general, all units must be handled with care.

The carton or case containing the unit must be kept dry at all times, and must be sheltered from the weather. It must not be subjected to shocks, excessive vibration or other rough handling. The carton or case will normally be marked with text or symbols indicating which way it is to be placed. Follow any instructions given, and ensure the case is always placed with its “top” uppermost.

The carton or case must not be used for any purpose for which it was not intended (step, table, etc.), and in the absence of other information, no other cartons or cases must be stacked o n top of it.

Lifting

A heavy crate will normally be marked with its weight, and the weights of other cartons or crates will normally be entered on the packing list.

• You must always check the weight of a crate before you attempt to lift it.

• You must always use lifting apparatus that is approved and certiﬁed for the load.

304699/A 15

Simrad ES60

Heavy units may be equipped with lifting lugs for transportation by crane within the workshop or installation area. Before you use a crane:

• You must check the applicable weight certiﬁcateforthecrane.

• You must check the security of the lifting lugs.

Ensure that all available lifting l ugs are used. Ensure the unit remains under control during the operation to avoid damage to the unit, equipment or personnel.

Heavy units may be transported using a f orklift truck. Special attention must then be paid to the position of the unit’s centre of gravity. The units must be properly secured to the truck.

Storage prior to installation or use

When a system, a unit or a spare part has been delivered to the customer, it may be subject to long time storage prior to installation and use. During this storage period, certain speciﬁcations must be met. The equipment must be preserved and stored in such a way that it does not constitute any danger to health, environment or personal injury.

1 The equipment must be stored in its original transportation

crate.

2 Ensure that the units are clearly separated in the shelves and

that each unit is easily identiﬁable.

3 The crate must not be used for any purpose for which it was

not intended (eg. work platform etc.).

4 The crates must not be placed on top of each other, unless

speciﬁc markings permit this.

5 The crates must not be placed directly on a dirt-ﬂoor. 6 Do not open the crate for inspection unless special

circumstances permit so.

• “Special circumstances” may be suspected damage to the crate and its content, or inspections by civil authorities.

• If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Re-preserve the equipment.

• If the units are not damaged, check the humidity absorbing material. If required, dry or replace the bags, then re-pack the unit(s) according to the packing instructions.

7 If the c rate has been opened, make sure that is it clos

and sealed after the inspection. Use the original p

acking

material as far as possible.

304699/A

Introduction

8 The storage room/area must be dry, with a non-condensing

atmosphere. It must be free from corrosive agents.

9 The storage area’s mean temperature must not be lower than

-30° C, and not warmer than +70° C. If other limitations

apply, the crates will be marked accordingly.

Note

Transducers must not be stored in temperatures below -20° C, or higher than +60° C.

10 The crate must not be exposed to moisture from ﬂuid

leakages.

11 The crate must not be exposed to direct sunlight or excessive

warmth from heaters.

12 The crate must not be subjected to excessive shock and

vibration.

13 If the unit contains normal batteries, these may have been

disconnected/isolated before the unit was packed. These must only be reconnected before the installation starts. Units containing batteries are marked.

Caution Units containing lithium or alkaline batteries must

be handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.

Inspection

An inspection must be carried out immediately after the unit(s) have arrived at their destination.

1 Check all wooden or cardboard boxes, plastic bags and

pallets for physical damage. Look for signs of dropping, immersion in water or other mishandling.

2 If damage is detected externally, you will have to open the

packaging to check the contents. Request a representative of the carrier to be present while the carton is opened, so any transportation damage can be identiﬁed.

3 If any units are damaged, prepare an inspection report

stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Send the inspection report to Simrad as soon as possible.

304699/A 17

Simrad ES60

4 If the units are not damaged, check the humidity absorbing

material. If required, dry or replace the bags, then re-pack the unit(s) according to the packing instructions.

Unpacking

General unpacking procedure

Normal precautions for the handling, transportation and storage of fragile electronic equipment must be undertaken.

Note

If the unit i s not to be prepared for immediate use, you may consider storing it unopened in its original packing material. However, it may be useful to open the case to check its contents for damage and retrieve any accompanying documentation.

Do not use a knife to open cardboard cartons - the contents may lie close to the surface, and may be damaged by the blade.

1 Check the carton before opening it to ensure it shows no

signs of dropping, immersion in water or other mishandling. If the carton shows signs of such damage, refer to the paragraph covering Inspection on receipt.

2 Place the carton on a stable work bench or on the ﬂoor with

the top of the carton uppermost.

3 In the absence of other instructions, always open the top

of the carton ﬁrst. The contents will normally have been lowered into the carton from above, so this will usually be the easiest route to follow. Care must be used when opening the carton to e nsure the contents are not damaged. D

o not

use a knife to open cardboard cartons

4 If the carton has been closed using staples, remove the

staples from the carton as you open it. This will reduce the possibilities of scratch injury to yourself and damage to the contents.

5 If a wooden crate has been closed using screws, always

remove them using a screwdriver. Do not attempt to prise the lid off with a crowbar or similar.

6 Once the carton is open, carefully remove all loose packing

and insulation material. Check for manuals and other documents that may have been added to the carton during packing, and put these to one side. Check also for special tools, door keys etc.

304699/A

Introduction

Unpacking electronic and electromechanical units

Electronic and electromechanical units will normally be wrapped in a clear plastic bag. Lift the unit, in its bag, out of the carton and place it in a stable position on the ﬂoor/work bench.

Inspect the unit for damage before opening the plastic bag.

Note

Beware of the dangers of Electro-Static Discharge (ESD) both to yourself and to the equipment, when handling electronic units and components.

Cables must never be used as carrying handles or lifting points. Do not break the seal to open a circuit board package before

the board is to be used. If the board package is returned to the manufacturer with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly.

Assuming all is well, open the bag and remove the unit.

Open the unit and check inside. Remove any packing and desiccant material that may be inside.

Unpacking mechanical units

Mechanical units may be heavy. Using a suitably certiﬁed lifting apparatus, lift the unit out of the crate and place it in a stable position on the ﬂoor/work bench.

Inspect the unit for damage and remove any packing material that may be inside the unit.

Unpacking transducers

Transducers may be supplied mounted to a hull unit (if any), or packed separately. Crates are normally identiﬁed by the order number and the serial number.

The transducer face must be protected by a rigid, padded cover (e.g. a wooden box lined with foam rubber) all the time it is exposed to the risk of physical damage.

Caution Once transducer is unpacked, great care must be taken

to ensure that transducer body and cabling is not exposed to any mechanical stress.

304699/A 19

Simrad ES60

Storage after unpacking

The unit must whenever possible be stored in its original transportation crate until ready for installation. The crate must not be used for any purpose for which it was not intended (eg. work platform etc.).

Once unpacked, the equipment must be kept in a dry, non condensing atmosphere, free from corrosive agents and isolated from sources of vibration.

Note

Do not break the seal to open a circuit board package before the board is to be used. If the board package is returned to the manufacturers with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly.

The unit must be installed in its intended operating position as soon as possible after unpacking. If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must then be reconnected during the installation procedure. Units containing batteries are marked.

Note

Units containing lithium or alkaline batteries must be handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.

Storage after use

If a unit is removed from its operating location and placed into storage, it must be properly cleaned and prepared before packing.

Cleaning cabinets

If a cabinet has been exposed to salt atmosphere while it was in use, it must be thoroughly cleaned both internally and externally to prevent corrosion.

1 Wipe the cabinet externally using a damp cloth a nd a little

detergent. Do not use excessive amounts of water as the unit may not be water tight. On completion, dry the unit thoroughly.

2 All surfaces must be inspected for signs of corrosion,

ﬂaking/bubbling paint, stains etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums for the unit. The mediums to be used will usually be deﬁned in the units’ maintenance manual.

304699/A

Introduction

3 Open the unit, and using a vacuum cleaner, remove all dust

etc. from the unit. Great care must be taken to ensure the circuit boards and modules are not damaged in the process.

Mechanical units

If a mechanical unit may has been exposed to a salt atmosphere while it was in use, it must be thoroughly cleaned both internally and externally to prevent corrosion.

1 If the construction materials and type of unit permits, wash

the unit using a high-pressure hose and copious amounts of fresh water. Examples are the lower parts of hull units (outside the hull) or subsea units

2 Ensure that all traces of mud and marine growth are

removed. Use a wooden or plastic scraper to remove persistent growth, barnacles etc. On completion, dry the unit thoroughly.

Caution Do not use a high pressure hose in the vicinity of

cables or transducers. Do not use sharp or metal tools on a transducer face.

3 If the materials or type of unit prevents the use of a

high-pressure hose, wipe the unit using a cloth dampened with water containing a little detergent. Examples are the upper parts of hull units (inside the hull) and hydraulic systems

4 Do not use excessive amounts of water as some components

on the unit m ay not be water tight. Wipe off the detergent with a damp cloth, then dry the unit thoroughly.

5 All surfaces must be inspected for signs of corrosion,

ﬂaking/bubbling paint, stains etc. Damaged or suspect areas m ust be cleaned, prepared and preserved using the correct preservation mediums. The mediums to be used will normally be deﬁ ned in the unit’s maintenance manual.

Cables

304699/A

Wipe clean all exposed cables, and check for damage. If a cable shows signs of wear or ageing, contact Simrad for advice.

Internal batteries

If the unit contains batteries, these may discharge slowly during storage. If the unit is to be stored for an extended period, disconnect or remove all internal batteries.

Simrad ES60

A suitable piece of insulating material can be placed between the battery and the electrical contacts to prevent electrical discharge. The battery can then remain in the unit, reducing the risk of it being misplaced during the storage period.

Caution Units containing lithium or alkaline batteries must be

handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.

Dehumidiﬁer

Place a suitably sized bag of desiccant material (silica gel or similar) into the unit to keep the electronic components as dry as possible.

Coatings

Spray the unit externally with a corrosion inhibitor (e.g. a light oil) before packing.

Re-packaging

Whenever possible, the unit must be stored and transported in its original packing material and/or crate. In the event that this material is not available, proceed as follows:

• Small units must be protected from damp by being placed within a plastic bag at least 0.15 mm thick. An appropriate quantity of desiccant material should be placed inside this bag, and the bag sealed. The sealed unit must then be placed in an appropriate carton or crate, and supported in t he container by appropriate shock-absorbing insulation ( polystyrene foam chips etc.).

• Large units must be placed in a suitable cardboard box or wooden crate. The unit must be protected against physical damage by means of shock-absorbing insulation mats. The box must be clearly marked with its contents, and must be stored in a dry and dust-free area.

Circuit board packaging

Circuit boards are delicate items. They may work year after year in an advanced product, but then fail due to a small spark of static electricity. For this reason, it is very important that they are properly handled and protected during shipping.

Introduction

Beware of ESD!

When you handle electronic circuit boards, you must beware of the dangers of electrostatic discharge (ESD), both to yourself and to the equipment. In order to ensure safe transport and storage, circuit boards and other electronic units will always be wrapped in a clear plastic protective bag, and the bag will be sealed.
