2 INSTALLATION PLANNING

Note: For installation in a previously installed trunk system, first read

the information about sonar room requirements. Then proceed

to the Hull Unit installation description.

2.1 Introduction

This chapter provides the marine engineers responsible the

information necessary to plan and install the sonar’s Hull Unit

according to Simrad’s requirements. Correct installation of the

sonar transducer is vital to the system’s performance. Several

variables must be taken into consideration, the most important

of which is the vessel’s construction. This guide is for use in

selecting the best location for the transducer and includes a brief

description of areas to be avoided.

Topics

→ Sonar room requirements, page 27

→ SP90 Sonar room layout, example, page 29

Note: Installation drawings must be supplied by the shipyard. The

installation must be approved by the vessel’s national registry

and corresponding maritime authority and/or classification

society. The shipowner and shipyard performing the installation

are responsible for obtaining and paying for installation

approval.

Simrad offers free advice for installation planning. Proposed

arrangements may be sent for commentary or suggestions

supplied by Simrad. The following drawings should be

submitted should assistance be requested:

• General arrangement

• Body plan and drawings of relevant bottom tanks and

coffer-dams

• Lines plan
