High Density EPS Foam Block | Seafastening | Umbilical Packing
Overview
The High Density EPS Geofoam Block is a lightweight, high-strength foam solution engineered for offshore seafastening, deck support, and cargo stabilisation.
Constructed from closed-cell expanded polystyrene (EPS), these blocks provide reliable load distribution, shock absorption, and void filling during vessel mobilisation and transport operations.
Used extensively across subsea, renewables, and oil & gas projects, EPS Geofoam ensures safe, efficient, and reusable seafastening configurations — protecting critical cargo and structures during offshore transit.
Key Features
High Load Capacity: Supports static and dynamic deck loads without deformation.
Lightweight & Easy to Cut: Simplifies installation and removal on offshore vessels.
Impact & Shock Absorption: Protects structures and subsea equipment from transit vibration.
Chemically Inert: Resistant to water, salt, and most hydrocarbons.
Reusable Material: Suitable for multiple mobilisations and long-term storage.
Custom Block Sizes: Cut to suit bespoke crating, seafastening pockets, and deck layouts.
