Global deepwater buoyancy and polymer specialist Balmoral Offshore Engineering has received American Petroleum Institute (API) approval for its buoyancy and clamping system for flexible riser pipe and umbilicals 黑料社� the first company in the industry to achieve such accreditation.

The API 17L specification stipulates the minimum requirements for the design, material selection, manufacture, documentation, testing, marking and packaging of flexible pipe ancillary equipment.

The buoyancy modules are supplied in two halves and attached to the flexible pipe using the company黑料社檚 patented clamping system. The modules are spaced along the flexible pipe to achieve certain riser configurations such as 黑料社榣azy黑料社�, 黑料社榮teep黑料社�, 黑料社榩liant黑料社� or 黑料社榃-wave黑料社�. They are a critical component of the riser package and are required to perform for the life of the field.

The API accreditation covers all materials, design, testing and manufacturing methodologies used in the system to provide uplift of up to 4.65Te at water depths to 10 000 ft.

To achieve the approval Balmoral worked closely with independent body, Bureau Veritas, on an 11 month development programme that consisted of four phases: quality audit; design review; material qualification; inspection and testing. Fraser Milne, Engineering and Projects Director with Balmoral, was in charge of the process and said: 黑料社淭he challenge in gaining this kind of approval is that we support our clients in deep

water provinces worldwide and each project uses different types of risers, flowlines and umbilicals according to specific operating environments.

黑料社淥f course, these require varying levels of buoyancy at differing operating depths within the water column. So, from one project to the next, the operating parameters to be considered have a huge impact on the size and shape of the end product.

黑料社淲hat is consistent, however, is the tried and tested design methodology, qualification, production and test method requirements that Balmoral undertakes using standard document templates to capture information complying with API 17L and tailoring the parameters to meet client and project requirements.黑料社�

Some areas where additional work was required to satisfy the accreditation has put Balmoral in a 黑料社渕uch stronger position黑料社� says Milne.

黑料社淲e boast an extensive track record in some of the most onerous operating conditions on the planet carrying out work for extremely demanding clients. As the industry continues its journey into deeper waters we differentiate ourselves by providing fully accredited, safe and highly cost effective design and manufacturing solutions.

黑料社淲e pride ourselves on our robust reliability track record and aim to deliver or exceed client expectations with every clamp and every buoyancy module provided.黑料社�

Other Balmoral products currently under final review by Bureau Veritas include bend stiffeners and restrictors. Full accreditation on these is expected by summer 2015.
