Single Carcass Submarine Hose

EMSTEC provide a range of high quality, high performance, oil suction and discharge hoses, extensively used at offshore moorings throughout the world. The EMSTEC Single Carcass Submarine hoses are utilized in high integrity sub-sea installations such as MBM, CALM, SALM configurations (i.e. Steep ‘S’, Lazy ‘S’, Chinese Lantern).

The EMSTEC hose fully complies with the requirements of the "OCIMF Guide to Purchasing, Manufacturing and Testing of Loading and Discharge Hoses for Offshore Moorings, Fourth Edition – 1991".

All hoses are designed and manufactured under a quality system in accordance with ISO 9001, and compliance with Pressure Equipment Directive (PED) 97/23/EC module H (hoses carry CE marking as required).
