Container Terminal DCT Gdańsk

Light, Strong, Inert Composite Covers Offer Simple Access Solution for Container Terminal DCT Gdańsk

Read the Case Study

Project Overview

Ports are busy highly trafficked areas, with many underground utilities which must be covered while easily accessible. The covering solution must be strong enough to withstand container carrying vehicles, the corrosive environment (saltwater, fuel) and all weather conditions.

As part of the extension of Container Terminal DCT Gdańsk (by construction company Besix) our Polish distributor Corrimex was approached to provide a strong, corrosion-resistant, easy to remove access solution.

Problem

Along the edge of the quay, a number of trench and sealed covers were required to cover access and valve pits. These required quick and easy regular access when cargo ships docked, yet needed to withstand very heavy loads (40-90 tonnes).

Solution

To cover the access pits, modular lightweight trench covers were supplied at a D400 load rating, allowing for safe two-person removal. For the water valve pits, sealed composite covers and frames were supplied at F900 load rating, which are light enough for safe single-person removal.

All Fibrelite covers are designed to be manually removed/replaced by either one or two people using the Fibrelite designed lifting handle(s) even at F900 (90 tonne) load rating. They also have an inherent resistance to corrosion and are hardwearing even in the harshest environment (extensively tested, see reports).
