While the problem can be complex, the best solutions should besimple. Our credentials in bespoke engineering – having worked in this field since 2003 – means we’re able to use our experience alongside an ethos of creative problem solving. This gives you a fully turn-key solution. Our capabilities combined with our facilities means that we begin with concepts and see it through design, manufacture, and testing. Following this, our team of engineers and technicians can support or lead the on-site or offshore use of the equipment. With our expansive track record in delivering engineered solutions to oil and gas operators and companies within the energy sector, we can and will provide the best solution.

Engineering Problem Solving and Bespoke Design

So you have a problem you haven’t seen before. Something has stopped working, stopped turning, fallen off. Or, something has been damaged by a technician, an ROV, a cyclone. Perhaps you’ve reviewed one of your processes and thought there must be a better / safer / quicker way. This is where we can help. It’s what we’ve been doing for all the oil and gas majors since 2003. Engineering problem solving and bespoke design are our bread and butter and the essence of Blakemere’s offering. We’re familiar with the unfamiliar. See our list of customers and our track records for assurance that we can help you.

Energy and Infrastructure

Not everything we do concerns oil and gas. Blakemere has been involved in projects outside oil and gas since the very beginning, and our presence in these fields continues to grow at an increasingly rapid rate. From designing connection systems for tidal turbines and wave energy machines, to cutting holes through dams and demolishing wharfs; we’ve been involved in some fascinating civil, energy, and infrastructure projects. Have a look at our track records for some details.

Concept Development and FEED

Got a complex job to do and don’t know where to start? Our
capabilities, backed by a wealth of experience, means that wecan help you arrive at the ideal strategy. Our internal processes follow robust concept selection procedures, FEED studies, and FMEAs to ensure the right path is taken from the very beginning. This gives you comfort and visibility prior to significant capital investment. We apply the same principles in various scales to everything we do, whether it be a small tool or the decommissioning of subsea field.


Blakemere offers a comprehensive range of services and equipment to ensure that your assets continue to perform in the most challenging environments. We excel at developing solutions to combat the degradation of marine assets and restore functionality where it’s been lost.

Damage Remediation

We can fix anything. From catastrophic damage and trawled
subsea infrastructure, to failed mechanisms and broken
interfaces; we will restore functionality to your subsea assets. In fact, some of our flagship projects have come about when it’s all gone horribly wrong:

  • A semi-automated remote flange bolting system after a christmas tree was snagged by an anchor chain.
  • A subsea machining tool that restored the sealing faces of a well head following a (very large) dropped object.
  • Restoring the functionality of a displacement initiator after it was trawled by a rampaging rig in a cyclone.
  • Fixing a leaking subsea safety valve control circuit by replacing a coupler on the tubing hanger. That’s like changing a spark plug on your car with the bonnet shut. Underwater. With a robot.

Sometimes the biggest challenge is convincing the client we can do what we say we can, and this is where our track records and case histories speak for themselves. Check them out.

Marine Growth Removal

From bulk removal of marine growth to polishing hydraulic
sealing interfaces on permanent subsea hardware, we have
developed a tool to address your issue. If not, we’ll create one. We specialise in all manner of cleaning brushes, both custom and generic, and acid supply systems of various capacities and designs. We also have HP and UHP zone rated pumps that we use for cleaning when the growth is more obstinate or the surface finish requirements are greater. Check out our case histories for examples of how we combine bespoke design with a light touch, or brute horsepower, to clean your subsea assets.

Calcareous Deposits

Calcareous deposits are an unwanted by-product of protecting equipment against corrosion and the bane of all operators’ lives. Our track record of equipment that addresses the effects of these deposits is supported by our ability to deliver acid in any quantity required. We specialise in getting acid to where it’s needed and keeping it there long enough for it to do its job. Think you can’t get acid where you need it? Ask us, we love a challenge.

Subsea Distribution System Remediation

Fact: water and electricity do not mix. Our mothers told us this and our professional lives as subsea engineers only support what she said. The operation of many of your subsea assets is reliant upon a complex subsea communications network of EFLs, SDUs, UTAs, UTHs, EDUs, SCMs, EDMs, and many other TLAs.

Fact: Blakemere has an ever-growing track record of restoring functionality and improving the serviceability of many elements of the subsea distribution systems of the oil majors.

SCM Remediation

Your subsea control modules are fundamental in sustaining
subsea production. Yet despite the criticality of uninterrupted service, SCMs typically require intervention or recovery more frequently than planned. Fine tolerances and close-fitting mechanisms combined with calcareous deposits and physical inaccessibility have thwarted many attempts to recover SCMs. Many issues have been encountered recovering SCMs that have been installed only a short period of time, some less than 12 months.

The greatest success during intervention with these production-critical components frequently depends upon the application of acid at the affected interfaces and the maintenance of high concentrations for prolonged periods. However, this fundamental requirement is often absent in the design of SCMs and their interfaces with subsea assets. Over time this has necessitated the development of numerous strategies and equipment to address these oversights in design.

Blakemere has assisted numerous operators in many varied
ways in the recovery of obstinate SCMs and the return of the permanent mounting interfaces to as-new condition. Existing equipment and capabilities within this solution line include:

  • Acid shrouds that envelope the entire SCM and mounting
    base to effectively and efficiently soak all components in acid, reversing the effect of calcareous deposits created by cathodic protection. If the gap between the SCM and the guide funnel is obstructed or insufficient, there’s a jacking tool to create the space required.
  • Shrouds and acid injection systems can be deployed to envelope and soak the mounting base as a method of remediation, or as a precursor to further remedial intervention, once the SCM has been removed.
  • Cleaning tools that safely and efficiently return the permanently installed hydraulic couplers to as-new condition using a combination of cleaning pads and acid delivered directly to the mating faces. For speed and efficiency, the couplers are cleaned four at a time (see the before and after images in the Inpex presentation).
  • Tooling that drills through the lower skirt of some SCMs that obstruct access to the hydraulic couplers and injection wands that deliver acid directly to the affected areas.
  • Jacking tools that apply a force directly between the mounting base and the underside of the SCM. The direct load path allows greater forces to be applied than possible through traditional extraction methods.

Anode Retrofits and Life Extension

Your infrastructure is still working and the price of oil is…ok. You want your asset to keep producing beyond its design life but nothing lasts forever, especially subsea. Blakemere has delivered hundreds of items to field operators seeking to renew the performance of their CP systems, or otherwise extend the serviceable life of their assets. From a simple clamp and a cable through to an anode skid, we have the facilities to design and fabricate what you need.

Sometimes the problem is a little more serious than the addition of an anode skid. You may be unlucky enough to have a fatigue crack in a jacket member and require a subsea machining tool to follow the crack and create a weld preparation, or even cut out a large coupon with an automated tool. And then perhaps you need a dry welding habitat to complete the remediation. Yes, we can do that too because we’ve done it before.


Sometimes it’s straightforward and you can draw from our extensive pool of off-the-shelf solutions. More often that’s not the case. The sheer diversity of offshore infrastructure dictates bespoke decommissioning solutions. Regardless, you can rely on Blakemere’s extensive capabilities supported by an extensive track record of success in decommissioning all manner of assets: onshore, offshore, in air, and subsea. The off-the-shelf solution not ideal? No problem. We specialise in the bespoke application of existing technology, adapting and applying proven methods to meet new requirements.


All equipment is designed in-house and continuously improved based upon experience, feedback, and lessons learned. A selection of our decommissioning equipment includes:

  • Diamond wire saws that will cut through anything. At our facility we keep various saws that span the range of 0-155” with larger sizes being developed as required.
  • Friction disc cutting for structures, pipes, and chains. These are remarkably versatile machines that have been adapted for a large number of bespoke applications.
  • Zone-rated high pressure and ultra-high pressure abrasive cutting for external and internal cutting of structures, pipes, and risers.
  • Flange bolt cutting tools that drive themselves around the flange. It’s able to cut on either side of the flange, including in the gap between the flanges. It’s ROV installed and the cut location is adjustable subsea.
  • For cutting requirements in hazardous areas, our hydraulic equipment is supported by our own zone-rated electric HPUs.
  • Subsea shears.
  • Subsea grapples.


The containment, or exclusion, of fluids and gases is fundamental to the integrity of subsea systems and the safety of people and the environment. So, when you have to decommission, disassemble, modify, or recover your assets and contain any substance in the process, you need a partner with experience developing solutions to suit your requirements. Blakemere is that partner.

Over the years Blakemere has developed a wide range of bespoke plugging solutions for all manner of applications: high and low pressure applications, high excursion and even non-circular solutions sealing against eroded bores, concrete bores, seam- welded pipe. Our track record is expansive and diverse. Many of the designs feature integral retention clamps and back seal testing capabilities. If the ideal solution doesn’t exist, we’ll create it for you.

Buoyancy Removal

Dismantling a string of distributed buoyancy from a riser while subsea is a complicated process. Blakemere has developed a tool to return buoyancy modules to the surface safely, irrespective of their orientation or proximity to other modules. On the other hand, if you want to install buoyancy modules subsea, we’ve done that too.
