Custom Manufacture Through the combination of its in house design capabilities, engineering expertise and extensive offshore installation experience, Sea-Struct can provide clients with custom designed and bespoke products such as Grout Tubes, Pile Plug Bags and Cross-over bags that can be tailored to meet their specific project needs. Additionally, Sea-Struct can manufacture its standard product line in larger dimensions to client specification.
Sea-Struct Groutbags Offshore Grouting
Diver Installed Supports The process of installing supports using divers includes comprehensive procedures for diver intervention. Features such as over-pipe straps, corner tie down fixtures and ball valve water vents that are incorporated into the Groutbag design assist with diver installation.
ROV Installed Supports Sea-Struct has pioneered the installation of Pipeline Freespan Supports in deep water using remotely operated vehicles (ROV). The combination of unique installation equipment and the implementation of procedures that have been successfully utilised to install more than 3000 bags has resulted in an effective and cost saving system. Supports to a massive 5000mm in height have been successfully installed using Sea-Struct ROV installation system.
Grouting Equipment In the field, Sea-Struct can supply all of the equipment required for the installation of its Groutbags including silo bulk cement storage and shipping containers. Please refer to Sea-Struct equipment flyers for further information.

Stabilised Base Pyramids provide an enlarged base, high payload, stable support for pipeline freespan correction. The standard SBP design provides clients with time and cost savings associated with positioning and filling the forms and the cement required. In addition, the SBP form also provides: • Improved load bearing characteristics • Improved lateral stability • Scour reduction • Application on sloping seabed
The SBP form construction comprises multiple compartments with internal structural partitioning and base height limiting straps to provide form shape during inflation.

GM Series Groutbags provide an economical solution to pipeline support and are used for small spans. GM forms can also be used in conjunction with SBP forms to support pipeline crossovers and can be applied, in various sizes, to a pipeline adding weight for stability. Typical examples of Grout Mat stability: • In shallow water where a vessel that is capable of handling pre-cast concrete mattresses cannot access the pipe • Where there are concerns that the application of Sea-Struct’s pre-cast concrete mattresses may cause damage to a cable or umbilical.
