Balmoral has introduced a number of subsea solutions over the past few years, including Balmoral HexDefence and Balmoral FibreFlex, scour and cable protection systems respectively for the offshore wind sector. The latest product solution to be brought to market is a bend stiffener connector.
Bend restricting devices, which include stiffeners and restrictors, are used across the offshore wind and traditional oil and gas sectors where there is a requirement to control the bend radius of a pipe, cable or umbilical.
They are usually attached at topside or seabed connection areas and are typically conically shaped polyurethane mouldings with a cylindrical bore that fits over the asset.
In seamlessly integrating dynamic bend stiffeners with offshore structures, the Balmoral BSC features diverless installation and an elevated level of operational performance.
Balmoral engineering and projects director, Fraser Milne, said: “With the BSC, operational readiness is achieved swiftly and we believe establishes an unparalleled benchmark for reliability and efficiency.
“By enabling a seamless fusion of dynamic bend stiffeners with offshore structures our commitment to pioneering engineering solutions for the offshore energy sector is again demonstrated.”
Diverless installation lies at the heart of this innovation while the design and manufacturing process adheres to API 17L standards. This commitment to operational efficiency is further highlighted by the incorporation of a reusable pull head which not only enhances installation timelines but also adds practicality to the overall process, the company said.
The full system consists of a lead-in cone, BSC and dynamic bend stiffener. The BSC is drawn through a bellmouth located beneath a floating platform. As the BSC latching system engages with the bellmouth the anchoring mechanism comes into action. This latch secures the mechanism during descent and maintains system stability as the anchors find their place on the tapered neck of the bellmouth.
The BSC will be on display at the Balmoral stand at Offshore Europe in Aberdeen.
