Fault Within a Wind Farm Inter-Array Cable Overview BPP Tech was engaged by an offshore wind farm operator to investigate a fault in an inter array cable, discovered during a pre-termination test. Testing of the recovered cable identified a faulted 8-metre section of the cable and this was targeted for dissection by BPP Tech at […]

Expert Witness Investigation and Dissection of Defected Cable
Expert Witness Investigation and Dissection of Defected Cable Overview After a subsea cable was observed behaving erratically and exhibiting handling difficulties during transpooling and load out operations, BPP Tech was engaged to investigate and report. Three principal topics were requested: The sum of these investigations revealed defects in cable design, manufacturing and handling, the consequences […]
Investigation into Root Causes of Cable Failure
Investigation into Root Causes of Cable Failure Overview A 1000 mm2 export cable had suffered a failure in the region of an Intertidal Joint (ITJ), located approximately 2.5 km from the onshore transition joint. BPP-Tech was engaged by insurers to perform an independent investigation into the potential root causes of the failure. BPP Tech found […]
Cable Damage Caused During Installation
Cable Damage Caused During Installation Overview BPP was engaged as an independent witness to attend the inspection of a damaged export cable currently undergoing installation. Following receipt of background information, BPP mobilised an engineer to site to witness operations, carry out a visual condition survey, and to report on the suitability of the inspection carried […]
Cable/Umbilical Structural and Installation Analysis
Cable/Umbilical Structural and Installation Analysis Overview Owing to the differing conditions, and hence requirements, of each subsea system nearly every cable and umbilical will have a unique design. In addition, as there is often no redundancy built into the vital communication link the umbilical becomes a very high cost/ risk product. Therefore minimising the risks […]
Umbilicals, Cables and Flexible Pipes: Buyer Beware
Umbilicals, Cables and Flexible Pipes: Buyer Beware Overview Since the earliest applications of flexible pipes and umbilicals in the offshore industry, BPP has been engaged in providing operators, contractors and manufacturers with specialist services for flexible pipes, including risers, and for helically armoured and steel tube umbilicals. These have included third party design verification, preparation […]
Standing the Test of Time
Standing the Test of Time Overview The offshore industry has many over used words and phrases, which often camouflage technical complexity and the criticality of form and function. Control umbilicals have been required since the first offshore installation and over the years they have become complex and vital engineered components for offshore production. Ensuring the […]
Scouring the Shallows
Scouring the Shallows Overview The disturbance to water flow patterns caused by seabed installations can result in localised erosion and, if left unchecked, this so-called scouring may threaten the integrity and stability of sub-sea foundations. With environmental concerns bringing ‘green’ energy sources such as tidal, wave and wind power increasingly into the energy mix, there […]
Risk Management: Science or Art?
Risk Management: Science or Art? Overview In one way or another the technical services that BPP offers are in the business of risk management, whether it be the design of an offshore platform that will not collapse for twenty five years, or the risk assessment of a process plant for the probability of an accident […]
Powering Up: The PowerCab JIP
Powering Up: The PowerCab JIP Overview BPP managed the PowerCab Joint Industry Project (JIP) on behalf of the four participating companies: BG Group; BP Exploration; DUCO (Technip) and Shell UK. The PowerCab JIP Work Programme concerns the development of subsea electrical power cable designs with high dynamic loading capacity. The project was carried out in […]
