Installation planning

Note For installation in an already installed trunk system, first read

through chapter “Sonar room requirements”. Then for an

already installed SQ4 or SR 240 trunk system, continue to

procedure “Installation of the Hull Unit“.

General

This chapter provides the necessary information for the ship

designer to plan and carry out the installation of the SP270 hull

system according to Simrad’s requirements. Study this chapter

thoroughly to achieve the recommended knowledge of the

procedures.

Note that individual installation drawings must be designed by

the shipyard, and the construction must be approved by the

classification authorities at the customer’s expense.

Simrad offers free advice for installation planning. The proposal

for the arrangement may be sent to Simrad for comments, or

may be worked out by Simrad. If such assistance is required, the

following drawings should be submitted:

• General arrangement

• Body plan and drawings of bottom tanks and cofferdam

• Sheer drawing

Location of the hull unit

The Hull Unit should preferably be located within 1/10 to 1/3 of

the ship’s length between perpendiculars (LBP), measured from

the fore perpendicular (FP). Refer to figure 1. Larger deviations

from this rule should not be made without consulting Simrad.

The Hull Unit may be located symmetrically on the centre line

of the vessel, or alongside the keel. When determining the exact

location, make sure that the transducer will have free view under

the keel (refer to figure 2 on page 3).

The Hull Unit trunk must be installed such that it will be vertical

under normal operating conditions.

Water inlets and protruding details which create turbulence,

should not be located in front of the transducer. For the same

reason, check that the shell plating in front of the trunk is not

damaged.
