BASIC INFO

ST High Holding Power Offshore Anchor

A more recent design of high holding power anchor with full class certification, available in sizes from 500kg to 30,000kg. Adjustable flukes are able to produce holding power ratios of between 30–50 times anchor weight. They are favored within the offshore industry for a range of applications from semi-submersible rigs to permanent moorings.

Mooring offshore anchors are currently one of the most versatile anchors available in the offshore rigging industry, so it is one of the most commonly used anchors for offshore rigs. It is an HHP (High Holding Force) anchor with an adjustable shank. This adjustable shank is ideal for replacing anchors to meet soil needs, rather than getting a new anchor every time you use it. Over time, this greatly reduces costs.

 

STS High Holding Power Offshore Anchor

A derivative of the ST with the addition of ‘shark teeth’ on the twin shanks makes this anchor ideal for enhanced performance in hard seabed medium and coral, etc.
