Design Validation Testing is a critical step in the path of ensuring a successful installation and operation to meet specifications and life expectancy of subsea products. At AES we execute detailed characterization and qualification programs as part of the initial system requirements.

Our team’s previous involvement with extensive testing programs from Submarine Rescue Diving and Recompression System (SRDSR) and High-Capacity Alongside Sea Base Sustainment (HiCASS) projects provided AES with in-depth understanding of Design Verification Test (DVT) programs.

As part of the DVT, AES performs intensive planning to deliver objective and comprehensive conformance testing and verify product specifications, interface standards, OEM requirements, and survivability requirements for transit, installation and operational loading scenario.

AES was appointed to perform full scale prototype testing on a subsea steel to HDPE joint solution. The extensive testing program is initiated to validate the design solution and the supporting analysis to ensure that the pipeline components will satisfy the stipulated and inferred requirements.

A custom build hydraulic test frame, controlled with a custom written Labview program has been developed that allows the subsea joint solution to be subjected to various load combinations including tensile loads, moment loads, torsion loads and hydrostatic loads in various magnitudes and axes simultaneously.

Case Study 3:

Launch & Recovery Testing of a 1000fsw rated Diving Bell for an increased in air weight

AES was commissioned by Veolia Environmental Marine Services to undertake the altering the in-air weight design of an existing 1000fsw rated Diving Bell not to exceed the Launch & Recovery Systems SWL and also to perform the in water hydro-stability tests of the diving bell and functional load tests of the L&R System under the survey of ABS and Shell. The particular challenge was to solve the diving bell's water entrance problem at the moonpool in a very short time frame without delaying the contractual liabilities. Read more…..
