Container Manufacture and Modification

Container externals and interior

Container Manufacture

Container-type structures afford the ideal method for installation of plant and equipment that has to be operational upon arrival at site.

Whether built with corner castings or crane lifting points, they are suited for transportation by Road, Rail or Shipping.

You tell us what you want to package and we will produce a packaging system individually designed for that purpose. The design process is fully computerised, utilising Autodesk AutoCAD and Microsoft Office software. In addition, 3-D modelling/CAD software is currently being introduced.

Container Modifications

Whether a transportable facility, or semi-permanent fixture, containers provide very robust, durable and, most importantly, a secure steel environment.

They are an extremely cost-effective alternative to building a traditional structure.  for most purposes planning permission will not be required.

If your need is simply to fit a couple of shelves or installation of valuable plant and equipment to creating a multi-link complex –

We have the expertise to provide the solution

Conversions to containers enable many new uses, limited only by the scope of your  imagination.

SIMPLY tell us what you would like to achieve and leave the rest to us.

We will customise the container to meet your needs

Global Marine

Internal and external views of Global Marine container

Global Marine operate this as a standalone unit or in conjunction with other portable modules to form a complete Cable Management Facility. It was fully fitted and commissioned in the factory prior to being installed on a “ship of opportunity” which was being used for laying under-sea communications cables

The Electrical Power Distribution System was carefully tailored to balance the “on board” power available with the multiple power requirements for the safe and efficient operation of the Cable Jointing Room.  Great care was taken to balance the electrical load and provide a high degree of protection from the diversity of power requirements

Each ship’s power cable was terminated in an MCCB enclosure before being linked to either a Transformer or directly to a Distribution Board.  Each outgoing power cable from a Transformer was also terminated in an MCCB Enclosure before being connected to a Distribution Board.

The Cable Jointing Room shown is provided with three incoming power sources, which feed eight different Distribution Boards wither directly or through a Transformer.  A total of 58 individual circuits are provided at 6 different voltage ratings.

The Cable Jointing Room was designed to operate worldwide and was provided with full air conditioning and climate control.

An array of Power Outlet Sockets are provided ranging from 440V 60Hz 3 pole 63 Amp to 110V 60Hz DP 15 Amp.  The sockets are employed for a variety of uses including portable power tools and sensitive testing equipment.
