1.2 Introduction

The mooring lug insert is fitted into the welded mooring lug ear on the mooring bracket and serves as a replaceable wear lining. The insert can be retrofitted at sea, or delivered pre-assembled on floating collars in production. With the insert, fish farmers only need to replace this wear piece instead of the entire mooring bracket when the insert has wear exceeding the replacement criteria.

Inserts are available in two sizes for FrøyaRingen mooring brackets, one type for FR400, FR450 and FR500. The other type is available for FR560 and FR630.

2 Interaction with other components

The insert consists of two parts and is attached to the mooring bracket with two bolts. The shackle for the bridle is attached to the insert and is connected to the bridle part. The insert is made of Duplex material.

3 Installation of the unit

The insert is attached to the mooring bracket with two bolts that are included in the kit. Figure 3.1 shows how the parts and bolts are assembled.

Figure 3.3: Mooring lug insert mounted in the mooring lug ear in the mooring bracket.

4 Installation on site

Dismantle and secure the bridle, install the insert in the mooring lug ear and reattach the bridle by the shackle in the insert.

5 Use

The mooring lug insert can be used on all pens where the mooring brackets have a U-shaped bracket for attachment of bridles.

6 Inspection and maintenance

Check the inserts when doing the monthly inspection of the mooring lug ears and replace the inserts if visual damage/breakage is observed or significant wear. Check that the bolts are in place and that the shackle is within tolerances.

7 Transport and storage

Shipped as general cargo.
