Petrol Tank Modification Works

R&D Specific
Challenges

Initially worked with Ricardo site team to understand their requirements (goal) and develop concepts as to how this can be achieved.

Once concept design was finalised and agreed, EAPL then developed the designs in detail, which included sourcing fixtures and fittings needed to meet customer requirements.

This enabled the project to be costed, tendered and awarded.

In the execution phase of the project we had to:

  • Develop and prove stainless steel welding procedures and have these third party approved (WPQR), develop the skills of the team and qualify them against the new procedures.
  • Develop methodology to manufacture the pipes and manway which where bespoke designs developed for the project.
  • Produce a methodology and conduct risk assessment for the conduct of the workson site. We only had access to half the tank farm at a time, with the other half still in use by Ricardo.
  • Continually revise the methods for delivering the installation onsite, adapting to the arrangements as we progressed works to ensure safety, quality and customer satisfaction was achieved.

Project
Scope

Provide development, design, procurement, manufacture and labour on site to complete the below

Item 1: Remove existing MS fuel filling and vapour recovery lines

  • Tanks in scope 11, 11X, 12, 12X, 13, 13X, 14, 15, 16, 17, 18Y, 18X and 18

Item 2: Install 3 off 2” stainless steel vapour recovery lines. (See figure 1)

  • Tanks in scope 11X, 12X, 13X, 17, 18Y, 18X and 18.
  • One line for 11X, 18 - one line for 12X, 18X, 18Y and one line for 13X, 17.
  • Lines manufactured from SCH 10 304L stainless steel seamed pipe and SW 150# fittings with slip on flanges.
  • Supply and install 7 off new 2” isolation valves for vapour recovery pipes installed by manways.  To be accessible from the walkways.
  • Nylon/rubber spacers to be fitted between all new pipes and brackets/clamps.

Item 3 – Install 7 off 3” stainless steel fuel filling lines. (See figure 2)

  • Tanks in scope 11X, 12X, 13X, 17, 18Y, 18X and 18.
  • Lines manufactured from SCH 10 304L stainless steel seamed pipe and SW 150# fittings with slip on flanges.
  • Supply and install 7 off new 3” isolation valves for fill pipes at filling point.
  • Nylon/rubber spacers to be fitted between all new pipes and brackets/clamps.

Item 4 – Replace 7 off existing manways with 600mm diameter manways. (See figure 3)

  • Tanks in scope 11X, 12X, 13X, 17, 18Y, 18X and 18.
  • Manufacture, supply & install 7 off new larger manways fully welded (24” STD A106 pipe with 15mm S275 plate flanges).
  • Mild steel fittings in manway covers to be similar to recently upgraded diesel tanks.  
  • Sounding pipes and strike pads to be moved on 2off tanks to accommodate new larger manways.
  • Gaskets and stainless-steel bolts included.

Item 5 – Supply 5 Blanking Flanges

  • 5 off 2” blanking flange plates required to seal off redundant pipe work on the decommissioned tanks in the middle.

Boskalis, Colwyn Bay Project

Specific
demands

This pipe once assembled would be towed out to sea, lowered to the sea bed, and commence pumping in stages.

EAPL would supply labour and technical support to assemble 83 pieces of very large diameter pipe, 800mm x 25mm wall thickness, each section would be 12 metres long to produce one pipe that measured around 996 metres long.

The whole project would be conducted on the foreshore at Colwyn Bay so extremely high profile with local and national media involved.

As the tender was progressing our client then requested all plant and equipment must be provided by the winning contractor.

Project
timescales

Due to many aspects surrounding this project, the tender process was demanding.

All criteria had to be agreed before being awarded with the initial enquiry received by EAPL on the 28th April 2022 and awarded to EAPL on the 09/05/2022.

The project timescales agreed was commencement on the 22/05/2022 and completed of this mobilization 2 weeks later.

Once completed a smaller team would remain on site to cut pipes back into 12-meter sections.

Development
works identified

To work with our client on feasibility of component assembly within the timeframe permitted, evaluating new assets to achieve the demands and again within the timeframe allowed.

New tenting arrangement and configuration on the beach so allowing weld free issues. Providing ongoing expertise in this project.
