all round protection for vessel and crew

DFENCE is a new and innovative vessel perimeter protection system, designed to thwart unlawful over-the-side access to ships, oil rigs and other marine platforms and installations.

Developed by our maritime security specialists and internationally-recognised piracy experts at Gray Page, the DFENCE system uniquely combines enhanced anti-climb properties with practical sea-going characteristics and shipboard utility.

#NoEasyTargets
security properties DISRUPTIVE TECHNOLOGY

The DFENCE perimeter protection system incorporates three outboard modules, each with a different profile, which makes climbing over it from below exceptionally difficult.

The planar surfaces of the knuckles, blades and the fishplate protection modules have been designed specifically to repel, deflect and destabilise ladders, poles, and other climbing apparatus.

As part of a layered approach to vessel and platform security, the DFENCE installation is both a highly visual statement of security posture and a physically disruptive obstacle to over-the-side boarding.i

sea-going characteristics shipboard utility

DFENCE not only has great physical security properties, it has also been designed to be easy to work with on board ship, as well as withstand the rigours of the seagoing environment.

  • Genuinely quick and simple to fit, unfit and refit.

  • Nests on standard 1000mm x 1200mm pallets for optimum storage when not in use.

  • As a modular system it will fit readily in the way of fairleads, mooring chocks and accommodation ladders, as well as go around corners.

  • Designed to accommodate different heights of fish plate and the variances in distance between fishplate and railings.

  • Will not trap water on deck.

  • Light and super-tough, the weight of the modules has been kept as low as possible without compromising strength and rigidity.

  • No components that will rust or rot, reducing significantly the costs of replacement modules and fixings.

  • Rotational moulded in UV15 high density polyethylene (HDPE), a material known for its toughness, rigidity and anti-weathering properties.

  • Safe to handle.

  • Recyclable.

  • High quality manufacturing.

  • Manufactured in ‘safety orange’ as standard, to make a highly visual statement of security posture, but can be custom-manufactured in a wide range of colours.

necessity is the mother of invention

Our Asset Protection division has been hardening ships against security threats such as piracy for many years.

Over that time we have devised various ways of protecting the perimeter of ships and other marine platforms, and latterly we have sea-trialled ‘security barriers’ produced by other companies.

The problem has been that while our solutions - and the other barriers that we tested - had some or all of the security properties we were looking for they weren’t as practical as they needed to be.

In the absence of a product on the market that did everything that we wanted it to do, we decided to develop our own.
