Insulation washer
The insulation washer is integral at fastener location, allowing use of a wide range of fastener materials while minimizing effects of accelerated corrosion due to dissimilar metals.
Fasteners
Can be supplied with a variety of fastening systems, suitable for a range of seabed from hard rock to softer rock options. Fasteners are exclusively 316 Stainless Steel which has a proven longevity in harsh environments.
Anchoring Recommendations
Hard Rock >25mPa: 150mm anchor studs embedded in rock with epoxy resin of tensile strength greater than 25mPa.
Soft Rock <25mPa: Anchor studs up to 1000mm long embedded with either epoxy resin or underwater grade grout.
Soft rock / Hard clay: Ground anchors up to 1500mm long embedded in seabed and pre-tensioned before use.
