navigating it can be a drain on resources and testing costs increase considerably through the stages. As a result, many designers can handle the simulated computer modelling of components at the early stages, but struggle when it comes to the rigorous field testing of full-scale prototypes occurring in the latter stages. Te most important stages of TRL begin at level four and five where full- scale prototypes are evaluated within an intended simulated or actual environment often with full interface and functionality tests. Replicating the downhole conditions that equipment will see in the field is not easy. Manufacturers typically use computer simulations or modelling rather than physical testing. Tis carries its own inherent risks, where unforeseen ‘real-life’ conditions are not factored into the models. Also the computer simulation of multiphase flows is often simplistic at best, and often requires physical testing to validate the computer models developed. Manufacturers often use computer modelling until a very late testing stage. Tey also often use expensive competitor owned testing facilities, which
NEW DEEPWATER TEST TANK LAUNCHED S
ubsea technology provider Forum Energy Technologies has unveiled a deepwater test facility and received industry accreditation for the
calibration laboratory at its new European Operational Centre in Aberdeen. The indoor test tank is one of the largest in the
North-east of Scotland and is dedicated to testing subsea tooling and survey sensors as well as work-class remotely operated vehicles (ROVs). Staffed by dedicated personnel, the test tank and
laboratory have a primary purpose to provide full control, certification and faster turnaround in preparing Forum’s rental inventory for hire. In addition, the firm
will also offer a full test and calibration service to customers. Ian Porter, VP for Manufacturing Subsea, says:
“Our continued investment in testing and calibration capabilities ensures that clients can be assured our systems have been prepared to the highest possible standards. This focus on quality products means clients know they are receiving ROV systems that will perform reliably in the field and safeguard the project costs.” The large freshwater tank, measuring 5m x 6m x 4.5m,
is fitted with overhead 10T crane, lighting, cameras and a viewing platform. The calibration laboratory has been accredited by Valeport and conforms to traceable procedures for the recalibration of Valeport CTDs (conductivity, temperature and density) and Sound Velocity sensors and parameters fitted on current meters, tide gauges, wave recorders and loggers. In addition, seven of Forum Subsea Rentals’
(FSR) engineers have undergone extensive training at Valeport on all aspects of the calibration of CTD and Sound Velocity parameters. l
