2.1 Mechanical Installation Introduction

The Seakeeper 2 is capable of producing loads up to 1,459 lbs (6.49 kN) at each of the four mounts and careful consideration should be given to foundation design to insure it is capable of transferring these loads into the hull. These loads do NOT include vessel motion accelerations, such as vertical slam loads which can be high for higher speed vessels. Seakeeper suggests a safety factor of 3.0 (yielding a safety margin of 2.0).

There are two methods of installing the Seakeeper 2:
1. Longitudinal Bolt-In Installation
2. Transverse Bolt-In Installation

It is assumed that the installer is familiar with mounting using mechanical fasteners to marine structures and has performed structural analysis to assure the structure to which the Seakeeper mounts can properly transfer the loads the Seakeeper creates into the hull structure. If the installer has any doubt about the ability of the structure to transfer the loads to the hull then the installer should contact a licensed naval architect or marine engineer to do a structural analysis.

The installer should review the following list of reference drawings to ensure the installation procedure is fully understood.
