Crimp fittings are used in subsea intervention to connect and disconnect two pieces of equipment hydraulically.

• A. JIC
• B. Crimp fittings
• C. ORB
• D. ORFS

Answer: (B)

The main idea is the type of hydraulic fitting method used to join hose ends in a subsea intervention. Crimp fittings are produced by crimping a ferrule and sleeve onto the hose end, creating a tight, integral joint between the hose and the fitting. This crimped connection provides a very strong mechanical grip and a reliable, leak-tight seal that can withstand the high pressures, bending, and harsh environment of deep-water operations. In subsea work, hose assemblies with crimped ends are commonly paired with standard connector interfaces to allow reliable connect–and–disconnect operations between pieces of equipment, even under challenging conditions.

The other options describe different sealing interfaces (such as JIC’s 37-degree flare, ORB’s O-ring boss, and ORFS’s face-seal) that specify how a connection seals, but they are not the crimping method used to form the end connection of a hose assembly. Hence, the term that best fits the description of a hydraulic connection method used in this context is crimp fittings.
