Oil, Gas and Sub-Sea

Supplying energy extraction infrastructure projects in a wide range of challenginging environments has long been a staple of Total Connections product offerings. We have a track record of supplying standard and bespoke solutions to the oil, gas and subsea sectors.

Our in-house design and manufacturing team has enjoyed working in partnership with some of the world's market-leading companies in this field. From sacrificial anodes, bespoke busbars, ingenious earthing solutions - the list goes on. Our standard products have a place too, but very often our bespoke stainless steel terminations and earthing solutions are most in demand for energy extraction infrastructure projects.

Oil, Gas and Sub-Sea Case Study

We were approached by a customer for a development project to rectify an ongoing issue with a standard SAK 16 terminal block. The customer had deployed these terminals in a marine environment, but found that the umbilicals on-board their floating production storage and offloading vessels (FPSO) were slowly drawing up sea water and leading to corrosion. The original zinc-plated steel terminals were lasting for just three months at a time.

Total Connections was asked to come up with a solution. The terminals needed to be chemically resistant to hydrogen, sea water and Methanol. We looked at alternative materials in the first instance and settled on two alternatives - Monel and Beryllium Copper (BeCu). We designed an earth block to fit into the original plastic moulding as a means of reducing cost. We then 3d printed the earth block in plastic to ensure a good fit into the casing. We designed the terminals in both materials to ensure that they were rated for 690V (ac) and 16A.

The customer ordered a quantity of terminals in both materials to test which enjoys the greatest longevity in the operational environment.
