COFFERDAM - ENGINEERING
DESIGN & FABRICATION
BPM can provide a specialist engineering niche for cofferdam design, fabrication, installation and execution of works as a direct development and support service to Offshore Vessel Operators. Our team have been designing and installing cofferdams of varying types and sizes for 30+ years, from small simple cofferdams to allow minor crack repairs on hulls, to giant 18m diameter 120 tonne cofferdams to fit under jack up rigs and allow repairs to spudcans. Cofferdams are frequently required to execute weld repairs to rig and vessel hulls where wet welding techniques cannot be used, or dry-docking facilities are not readily available. Our Engineering and Consultancy team use the latest CAD software, 3D modelling and Finite Element Analysis programmes to design and analyse a vast range of equipment and systems to support the projects.
COFFERDAM TYPES
Cofferdams fall into three main categories:
Our team of naval architects and marine engineers can design a cofferdam system to suit any application across the marine industry. Although typically manufactured from steel we also offer aluminium cofferdams and even ones created using flexible membrane technology.
Applications for cofferdams are as wide and varied as can be imagined and typically include:
