Scots engineers claim new double-deck platform jack-up barge could save offshore wind and oil companies $100,000 a day (and create 5,000 new shipbuilding jobs)

Glasgow-based Celtic Design Consultants (CDC) have announced that their new double-deck, self-propelled oil platform jack-up  barge could save offshore companies more than $100,000 a day.

The Heron DP2 jackup design features a modular construction which means that it is highly customisable and so can easily and cheaply be redesigned for different projects.

The Naval Architect for the project, said: “The CDC Heron has been created by ‘thinking outside the box’. Nothing is in prototype, or first in series. All equipment and functions comprise tried, tested and proven methods for delivery [which] fully adhere to global legislation, regulatory obligations and safety standards.

“Customers can build and pre-outfit CDC Heron modules in different locations, giving them greater flexibility and control over quality and build costs.”

What is most impressive about the design is the breadth of ways in which it saves time and money. Its creators say the Heron:

  • has a lighter hull and is self-propelled capable of using dual fuel – meaning a reduction in transit and transportation costs.
  • can house 120 people to North Sea Regulations – reducing reliance on weather windows and cutting the cost and downtime associated with rotating personnel on and offshore.
  • can operate in deeper water than traditional jackups. It can operate in harsher environments and accommodate more personnel than any other rigless jackup on the market.
  • has a method of changing all 3 blades on an offshore turbine, (that is 3 blades off and 3 blades on) in less time than it takes to currently rig up and remove 1 blade, all the while not affected by weather.
  • uses the latest in renewable energy, heat recovery and thermal insulation – cutting operating costs and carbon emissions.

The Heron uses modular and mirror design principles meaning you can specify an individual vessel’s size and capacity – without major redesign costs. Heron modules can be built and pre-outfitted in different locations – giving greater flexibility and control over quality and build costs.

The technology uses extensively tried, tested and proven methods to deliver more for less, and all the while adhering to global legislation, regulatory obligations and safety standards.

The system is currently being showcased at DecomWorld North Sea conference in Aberdeen.

Celtic Design Consultants are the owners of the unique design for a multi purpose vessel – with patent pending. Iain Steven at CDC explained:

“We really wish to develop and build the Heron in Scotland.

“There are various facilities where this could be undertaken, Clyde and Fergusons for one would be ideal. If the Germans and the Dutch can develop and build high end vessels – profitably –  why not Scotland?

“Building one Heron jack-up vessel could probably result in more than 5,000 new jobs.

“There are more than 3,000 wells to decommission in the southern North Sea, at around 25 days per well, this equates to a requirement for 10 of our Heron vessels, to carry out  plug & abandon’ work on the wells in the North Sea, which would keep 10 Heron- vessels occupied for over 20 years

“The use of the Heron, has benefits and major costs savings for the offshore wind sector, in helping to bring down the costs per megawatt/ hour, towards parity with shore based generation from coal, gas, oil and nuclear.

“The boost to the offshore sector, providing genuine cost cutting is where we have worked with a two major international service companies, developing the costs for a major oil company contract, with calculated savings to the oil majors of up to US$ 102,000 per day, for each vessel, for each day it operates in the North Sea, when taken as an integrated program.”
