Hose Connector Assembly With Latch for Marine Riser Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slip joint designs in marine riser systems are inadequate for managed pressure drilling (MPD) due to limited pressure sealing capacity, especially under wave motion, which prevents the use of these systems for MPD operations.
Innovation Solution
A connector assembly for connecting hoses to a tubular element, featuring a tubular housing with a main passage and a side passage, a hose connector with a pipe portion that mates with a connector tube, and a latch to secure the connection, allowing for hydraulic operation and preventing separation, along with an alignment structure and suspension parts for flexible installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional slip joint designs are used, then the system allows movement accommodation, but the pressure sealing capacity is limited
Solution Approach 1:
The connector assembly is divided into separate components: a connector body with sealing elements, a hose connector, and a latch mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall system flexibility and sealing capability.
Solution Approach 2:
The connector assembly incorporates a latch mechanism that can be moved between engaged and disengaged positions, allowing the connection to be dynamically adjusted. This enables the system to maintain secure sealing during operation while allowing for installation and removal operations.
2Reliability
If the connector assembly uses a latch mechanism, then the connection security is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is designed to be operable by the user without requiring additional tools or complex operating procedures. The latch provides automatic engagement and locking when the hose connector is inserted, and can be easily released by the operator to disconnect the connection.
3Reliability
If the connector tube and pipe portion are securely engaged, then the leak-proof connection is achieved, but the ease of installation and removal decreases
Solution Approach 1:
The latch mechanism transitions between a locked position that secures the connection and an unlocked position that allows easy separation. This dynamic capability enables the connection to be both secure during operation and easily installable/removable when needed.
Solution Approach 2:
The latch mechanism replaces complex threaded fastening or welding systems with a simpler mechanical locking system that achieves equivalent or superior sealing while being much easier to install and remove.

AI summary
A connector assembly for connecting a hose to a tubular element. The connector assembly includes a housing, a hose connector, and a latch. The housing encloses a main passage which is parallel to a longitudinal axis of the housing and which has a side passage extending through the housing from an exterior of the housing into the main passage. The side passage extends through a connector tube mounted on an exterior of the housing. A hose connector is secured to an end of the hose and engages with the connector tube to connect the hose to the tubular element. The hose connector comprises a pipe portion which mates with the connector tube to connect an interior of the hose to the side passage. The latch urges the connector tube and the pipe portion into engagement and prevents a separation thereof.
