SB-100-XX Operation and Installation Manual

1. INTRODUCTION

SKIPPER SB (Single Bottom) Sea Valve 100 mm

The SKIPPER SB Sea Valve 100 mm is used for installation of: SKIPPER speed log sensors and echo

sounder transducers tted with adaptors for XB-100-XX

1. Echo Sounder transducer type (50, 200 and 50/200 kHz).

2. Speed log sensors: DL2, DL21, DL1, DL850(270kHz), EML224.

Caution! Be aware that the Sea Valve contains high precision parts and therefore proper

handling when mounting is essential for the nal result.

When handling the Sea Valve, all lifting devices must be attached on the outside of the valve. It is very important to not insert any chains, wire, rope or any other device into the valve chamber. This to avoid damaging and any kind of pollution of the Sea Valve.

The SKIPPER SB Sea Valve 100 mm is delivered partly assembled for transport. The parts necessary for

nal assembly will be found packed in a box delivered with the Sea Valve. First of all, it must be decided

where the Sea Valve should be installed. Normally, this will be in the fore part of the ship, in the centerline,

or as close to the centerline as possible. Optimal system operation is achieved by tting the transducer/

sensor as deep as possible on the hull.

• The active surface of the sensor must be installed with front face a maximum of +/-1 degree to the ships horizontal plane. (2 axis Speed Logs).

• The active surface of the transducer must be installed with front face a maximum of +/-7 degree to the ships horizontal plane. (Echo Sounder).

Do not mount transducers close to the bow thruster propeller outlets, or aft of other hull installations (outlets, vents or other protruding details) who may create aeration or turbulence.

It is necessary to select a part of the hull that is submerged and free from turbulence and aeration under all load and speed conditions, and to avoid positions where air is trapped in heavy weather.

If a at, horizontal section is not available for transducer tting, the shipyard must construct a suitable bed. Welding seams in this area should be smoothed and rounded o, in order not to create turbulence or aeration

at speed.

Protect the active element of the transducer/sensors during transport and installation, and

do not paint the surface.

The Sea Valve should be placed in a service accessible place, large enough for installation and disassembly of the sensor unit. See drawing: “Space considerations”.

Important

”Sensors for Speed Log and Echo Sounder are delivered with a xed cable. Attention must be taken

to allow easy replacement/pulling of new cable during maintenance”.

SKIPPER Electronics AS will recommend installation positions if GA-drawings (General arrangements), lines drawings and frame drawings are made available for study.

Condition.

The welding to hull structures and structural support of the items may be subject to separate approval by

classication societies for each installation on board a ship.

Note: All “Item numbers” references on the following pages, can be found on drawing “Illustrated parts list.

Assembled” (unless specied).

Welding the Bottom Flange in Ship`s Hull

SKIPPER Electronics AS

SB-100-XX Operation and Installation Manual

3. WELDING THE BOTTOM FLANGE

• When the position has been decided, a hole for the 220 mm bottom ange is cut in the hull.

• The bottom ange, Item (1), is welded into the hull. Standard welding practice, methods and procedures should be observed, but may vary. (See welding notes).

Attention:

The bottom ange is a part of the Sea Valve that is machined with high accuracy and it should be protected after mounting to avoid damage to the bottom ange surfaces. This to avoid leakage. If the

valve is pre-mounted, be sure to protect the valve from being polluted by welding debris.

WELDING NOTES!

All bottom parts and anges for welding are precisely machined parts. During welding of these parts to the ship’s hull plates, careful attention must be paid to avoid construction strain on the bottom

parts and anges.

• Let parts cool down during welding.

• Over heating may change t and form and result in non-conformity with intended sensor/ transducer.

• Welding to thick hull steel plates will exert high stress on bottom parts and anges.

• Especially care must be taken during welding of stainless steel anges.

• Work must be performed by a qualied and certied welder.

4. SEA VALVE ASSEMBLY.

Caution must be taken when mounting seavalves that all parts are aligned correctly, and that the inside is clean. DO NOT use liguid sealants, and DO NOT paint the inside of a valve.

Assembly SB-100-SA

Step 1

• Place 1.5 mm gasket, Item (18) on top of Bottom Flange, Item (1).

• Then place the Main element, Item (6) on top of the Bottom Flange. The 16 mm nuts and washers should be mounted, not tightened. (Align parts before tighten nuts).

• Place a 1.5 mm gasket (item 18) on top of the main element, Item (6).

• Mount the intermediate element, Item (15) on top of the main element.

Step 2

• Place the aluminium alignment tool (2 x part SB-6033 in mounting kit), all the way, into the sea valve to ensure correct alignment of elements before bolts are tightened.

• Tighten 8 nuts valve to bottom ange.Torque: 130Nm

• Tighten 8 nuts Intermediate element to valve.

• Remove the aluminium alignment tool.

The alignment tool height is about 37mm higher than top of intermediate element on the gate valve SB-100-SA.

13. MAINTENANCE

1: Speed log performance may be eected by growth, shell, etc on sensor head.

Sensors may need carefully cleaned for growth to regain performance.

2: Sea valves consist of moving mechanical parts. Greasing of mechanical parts may be considered to ensure operation and avoid corrosion. Sea valves installed in wet areas (ballast tank etc) should be regularly inspected and greased.

3: Dry docking. Gaskets and o-rings may be considered to be replaced during dry docking period. Inspection of sea valve operation should be considered before a dry docking period to have any spare parts available at dry docking.

4: O-rings are included with sensors and should be replaced when/if sensor is replaced.

Maintenance Tasks for inactive sensors

(If the system is to be o / and the vessel static for over 6 months (cold water), 3 months warm water).

When closing the vessel.

• Turn o unit at power, both Display and transceiver.

• Mark the alignment of the sensor on the gate valve and sensor ange/pole.

• Lift the sensor into the gate valve and close the valve.

• Grease the valves external moving parts When restarting

• Heat the areas containing display, to allow condensation to evaporate.

• Lift and inspect the sensor head (or send diver). Carefully clean away growth.

• Redeploy the sensor taking care with alignment.

• Start the system.

• On rst test, check alignment (Head Err in the calibration screen).

Dry docking in temperatures below freezing point

If vessel is to be dry docked in temperatures below freezing point water remained inside sea valve may cause damage to sea valve or sensor/transducer.
