Subsea control systems support
Through our extensive industry experience and knowledge of subsea production systems, the aim of the support contract is to optimise system availability and reduce operational expenditure over the remainder of the field life, while fully aligning with current industry standards.
Subsea tie-back development
We provide ongoing assistance to an independent operator. This includes engineering and design of both subsea and topsides equipment. We provide interface management from concept through to commissioning prior to production.
Subsea Control Module replacement and span rectification
The project was to reinstate a subsea well the client required to replace the subsea control module and rectify the scour induced spans on the subsea spool. Our personnel developed the procedures for the Subsea Control Module (SCM) replacement and oversaw the testing of the replacement SCM. Additionally organised the survey of the span, performed the spanning calculations, specified and oversaw the span rectification works.
Decommissioning services
We provided subsea engineering support to the client as part of the decommissioning of a subsea field. This was provided on an “as required“ basis to reflect the nature of the workload. This approached provided the required services at a greatly reduced cost compared to the traditional approach.
Valve rectification
Involvement started with the request to inspect a subsea valves prior to its mobilisation on the DSV and we found that te valves supplied were manual operation as opposed to hydraulic. Using our extensive contacts, we sourced the actuators and organised the change out on the valve including flushing all within 48 hours preventing slippage of the vessel mobilisation.
Asset integrity
A client wanted to extend the operating life of their existing offshore structure asset and required to replace the cathodic protection. We carried out a survey to determine the best installation points and provided a ROV-installed retro-fit anode solution to reduce costs.
Pull-in cable method for offshore wind turbines
An offshore operator asked us to review the installation method to install the HV cable from the underwater J-tube of the bottom of the turbine to the topside nacelle. We proposed a method that reduced the installation time and complexity of the operation.
Fast-tract scale squeeze operation
An operator asked if we could provide an emergency quick disconnect system for a scale squeeze operation on a fast-track basis. We identified and selected a cost-effective method which was delivered on time.
